IB-23C650 INSTALLATION INSTALLATION GENERAL Read these instructions thoroughly before starting installation. Installation personnel should be qualified technicians. Observe all electrical code requirements and safety standards during installation. Installing the controller involves: • Unpacking • Mounting • Wiring Connections Displays and Cleaning The display is protected by an overlay that can be removed after installation.
IB-23C650 INTRODUCTION Notes: 1. When mounting housing in panel cutout or rack and panel mounting bezel, turn retaining screws until point of screw touches rear of panel or bezel. Overtightening of retaining screws will distort housing. Housing must be square after retaining screws are tightened. 2. MODCELL 2051R does not use the gasket and has a bezel width of 2.735” (69.47 mm). The panel cutout may be for the 2050R Figure 1. Mounting Dimensions.
IB-23C650 INSTALLATION MOUNTING The controller must be installed in an approved enclosure or installed in a means acceptable to the authority having jurisdiction for electrical installations. Select a mounting location where there is minimum vibration. The ambient temperature must be between 32 and 131°F (0 and 55°C) with a relative humidity of 25-95% RH (noncondensing). The panel must provide rigid support for the 3.2-pound (1.45 kg) controller and any other panel devices.
IB-23C650 INSTALLATION WIRING GUIDELINES The power wiring connections and input/output (I/O) connections are made with the controller installed in its operating location and with the power off. The rear view of the controller housing in Figure 2 shows the terminals available for inputs and outputs (rear cover removed). CAUTION Do not connect any wires to terminals 36, 37, 38, 39, and 40. Connections to these terminals can cause an instrument malfunction. The recommended wiring procedure is as follows: 1.

IB-23C650 INSTALLATION POWER CONNECTIONS WARNING Avoid electrical shock. AC power wiring must not be connected at the distribution panel (ac source) until all wiring procedures are completed. All power wiring must be in compliance with the requirements of the National Electrical Code or Canadian Electrical Code. In any installation where the power source does not have one side of the line connected as a neutral conductor, both sides of the line must be overcurrent protected.
IB-23C650 INSTALLATION GROUND CONNECTIONS The primary power ground system consists of the plant electrical ground (equipment grounding conductors). AC ground and chassis ground are connected when the termination housing is connected to the control module. If this path is insufficient to dampen out noise spikes on the ac line, the chassis ground may be connected directly to panel ground. The circuit common for all signals is negative.
IB-23C650 INSTALLATION The combination device suppresses transients and effectively reduces other noise forms such as electromagnetic (EMI) and radio frequency (RFI) interferences. These devices can be connected to multiple units to reduce overall cost. Input signals • Twisted wire pairs are essential. The wire type should be stranded, not solid. The largest wire gauge allowed is best and the more twists per foot the better. A 2-inch lay (6 twists per foot) should be the minimum used.

Pressing the UP key provides ramp/soak status such as run/hold, time left per segment, active segment, cycle, reset and skip. See operation of Ramp/Soak.
IB-23C650 BASIC OPERATION BAR GRAPHS Three 50-segment bar graphs provide visual indication of process, set-point and either output or deviation. Process Variable Set-Point Variable Output Process Variable Set-Point Variable Deviation (as set up in the Inputs Menu) Deviation bar shows a minimum of two highlighted lines (both highlighted when deviation is zero). Deviation is shown above or below these lines.
IB-23C650 BASIC OPERATION RESTART Power up mode, set-point and output conditions can be defined so that at an instrument power up condition the controller will assume these positions and values. Power up data is stored in non-volatile memory and is read into the operating memory at instrument power up. Controller mode at power up is defined in the BASE CFG MENU and may be set at auto, manual, or last, where last causes the controller to power up in the same mode as it was when power was lost.
IB-23C650 BASIC OPERATION OPERATION IN AUTOMATIC MODE This section describes operations for local set-points, remote or multiple setpoints, and A/M ratio bias while the controller is in the automatic mode. For automatic ramp/soak and totalizer operations, refer to those operations sections. Note: If tune or configure passwords have been employed, the passwords will be required to change any values. Automatic Operation with Local Set-Point [AUT] indicates that the controller is in automatic mode.
IB-23C650 BASIC OPERATION Automatic Operation with Remote or Multiple Set-Points The controller may be in either auto or manual as selected in the power up mode section of the BASE CFG MENU. If the controller is in automatic, the front face will resemble the example below. Note: Remote set-point requires the option board be installed. [AUT] indicates that the controller is in automatic. The set-point may be [LOC], [LO2], [LO3], [LO4] or [REM], depending on which set-points were enabled in the SETPTS MENU.
IB-23C650 BASIC OPERATION To perform a set-point bumpless transfer, complete the following steps: 1) With set-point displayed, press the R/L key to advance the controller through the menu-enabled set-points. [BAL] appears in the third status display. 2) Press the UP or DN key until the lower engineering display reaches “0.“ This adjusts the active set-point to the value of the new set-point, in this case the value of LO2. 3) Press the scroll key to enable the new set-point.
IB-23C650 BASIC OPERATION Automatic Operation with A/M Ratio Bias If ratio, bias or ratio/bias was enabled in the RAT BIAS MENU, the instrument display will resemble the examples below. [AUT] indicates that the station is in automatic mode. Ratio and/or bias source is local or remote as selected in RAT BIAS MENU (remote requires installation of an option board). Remote/Local switch is disabled [RAT] indicates that the ratio value is displayed in the lower engineering display.
IB-23C650 BASIC OPERATION AUTO/MANUAL TRANSFER Transfer from auto to manual is accomplished by pressing the manual key. Either of the digital inputs may be used to select manual if configured to do so. When the controller is in manual mode the upper status display will show [MAN]. Transfer from manual to automatic is made by pressing the auto key. Either of the two digital inputs may be used to select auto if configured to do so. When in automatic, the upper status display will show [AUT].
IB-23C650 BASIC OPERATION Auto/Manual Transfer for On-Off Control If the controller is set up for on-off control, the bumpless transfer feature does not apply when switching from automatic to manual. When switched to manual, the on-off controller output is always initialized at 0%. The transfer is bumpless only if the automatic output happens to be at 0% when switched. Operation in manual is the same as for a time proportioning controller.
IB-23C650 BASIC OPERATION OPERATION IN MANUAL This section describes operations for local set-points, remote or multiple setpoints, and A/M ratio bias while the controller is in the manual mode. For manual ramp/soak and totalizer operations, refer to those operations sections. Manual Operation with Local Set-Points The instrument is initially in manual mode with set-point displayed in the lower engineering display, as indicated by [SPT] in the third status display.
IB-23C650 BASIC OPERATION When the controller is set up for on/off control, the manual output is a time proportioning signal. This gives the output infinite adjustability between 0 and 100% rather than limited to the two-state 0 and 100% values of the automatic mode. In manual the output can be adjusted to any value needed to maintain the process at the set-point.
IB-23C650 BASIC OPERATION Press the scroll key to display the output in percent in the lower engineering display. [OUT] appears in the third status display. DN/UP status display indicates the UP and DN keys are active and can be used to adjust the output value in manual. Press the scroll key again to return the set-point in the lower engineering display. Remote or multiple set-point transfer is made by pressing the R/L key (press and release) [BAL] appears in the third status display.
IB-23C650 BASIC OPERATION Use the following steps to prepare to switch from a local to a remote set-point: 1) Press the R/L key until [REM] is displayed in the middle status display. 2) [BAL] appears in the third status display with the difference between the remote set-point and the current setpoint displayed in the lower engineering display. 3) Press the UP or DN key until the lower engineering display reaches “0.“ 4) Press scroll to enact the remote source as the new set-point source.
IB-23C650 BASIC OPERATION Manual Operation with A/M Ratio Bias If ratio, bias, or ratio/bias was enabled in the RAT BIAS MENU, the instrument display will resemble the examples below: [MAN] indicates that the station is in manual mode. Ratio and/or bias source is local or remote as selected in RAT BIAS MENU (remote requires installation of an option board). [RAT] indicates that the ratio value is displayed in the lower engineering display.
IB-23C650 BASIC OPERATION OPERATION USING DIGITAL INPUTS Digital inputs 1 and 2 can be used to control auto/manual transfer, acknowledge alarms, start totalization or ramp/soak operations, and select between enabled local or remote set-points. This section discusses using digital inputs for auto/manual transfer and set-point selection. For information on totalization and rampsoak operations, refer to the Totalization Operation and Ramp/Soak Operation sections.
IB-23C650 BASIC OPERATION If the digital input action is configured to be REVERSE, a closed contact will be treated as an open contact and vice versa. Note: Unless “A/M key lockout” is enabled in the DIG INPT MENU, the controller mode can be changed at the front panel regardless of the digital input state, causing possible conflict. To effect auto/manual transfer using digital inputs, complete the following steps: 1.
IB-23C650 BASIC OPERATION 2. Select whether to lock out the front panel from making set-point transfers, whether transitions are allowed between local and remote set-points, and the digital input action (DIRECT or REVERSE). 3. Choose which set-points to select between in the digital set-point selection list (e.g., LOC, LO2). Refer to Table 3 for information on the DIG INPT MENU. 4. Enable the digital input in the DISPLAYS MENU.
IB-23C650 BASIC OPERATION A transition in the state of either digital input (opened to closed, or closed to opened) will now cause a set-point transfer. For example, if the digital inputs are set up for set-point selection between LOC, LO3, LO4, and REM (using DIRECT action, with Input 2 enabled and local/remote transfer allowed), a state change of the digital inputs to DI-1 closed and DI-2 opened will cause a transfer to LO4.
IB-23C650 BASIC OPERATION combination of the four display alarms. Monitoring and acknowledging alarms are basic operator activities. Acknowledgment of alarms may or may not be required depending on the alarm set up in the ALARMS MENU. During power-up the alarm relay(s) remained powered down until an accurate process input reading was made. Relays selected as alarms will be in a fail-safe condition (powered when alarm is not active) until the alarm is active.

IB-23C650 BASIC OPERATION Alarm Messages An alarm is active when the process input (PROC), input 2 (INP2), control output (OUT), or deviation value (DEV) exceeds its alarm limit. When an alarm is active, the alarm indicator flashes and the front panel alarm message for the appropriate high (HI) or low (LO) turns on and flashes alternately with the process display. Any such configured alarm output relay is also active.
IB-23C650 BASIC OPERATION When the alarm finally stops, the alarm indicator will go out. If there is an alarm at one limit that has not been acknowledged (e.g. HI), and then the process subsequently trips the alarm at another limit (LO, HI-HI, or LO-LO), only the highest priority unacknowledged alarm will flash. If the low alarm remains when the alarm is acknowledged, the high alarm will extinguish and the low alarm will assume a steady-on condition.
IB-23C650 BASIC OPERATION STARTUP Procedures may vary from application to application, depending upon individual requirements and controller setup. The initial operating mode (usually manual), the set-point source (usually local), set-point value, and controller output can be configured for specified safe values when power to the controller is first applied. Each time a control application is first started up, check all these items before turn-on.
IB-23C650 BASIC OPERATION 4. Manually adjust output of controller to bring process variable up to final value. Ramping the output should be slow enough to allow the process to respond without overshooting the required control point.
IB-23C650 TUNING TUNING MANUAL TUNING The controller response parameters: Gain (P), Integral (I), and Derivative (D) are adjustable over a wide range of values to accommodate many different process characteristics. After the controller is installed in a specific control application, these response parameters must be tuned to the characteristics of the process so that overall system performance is at its best.
IB-23C650 TUNING Tuning Procedure The following procedure for tuning a controller is applicable to controllers set up for P (gain), PI (gain plus integral), PD (gain plus derivative), and PID (gain plus integral plus derivative) responses. If a recorder is available to record the process variable, it will be helpful in determining optimum controller settings. 1. Start up controller in manual mode as described in the Setup section. 2. When process and set-point are together, switch to automatic mode. 3.
IB-23C650 TUNING Figure 17. Process Recovery Cycle with Optimum Response Settings Increasing the gain setting increases cycle B relative to cycle A. If the controller has gain response only, no further adjustment is required. If the controller has two or three responses, proceed to Step 7. 7. Measure the period (P) of oscillation in minutes. The period is the time required for one complete cycle. 8. Calculate I (integral) and D (derivative) values as follows: a.

IB-23C650 TUNING AUTOMATIC TUNING Automatic tuning (autotune) is an on-demand user activated feature which automatically calculates either PI or PID response values based on process reaction during an autotune cycle. This is accomplished by manipulating the controller output to effect a periodic response by the intended process. The autotune cycle requires 6 process oscillations to determine the tuning parameters. The controller output and a typical process response are as shown in Figure 18.

RESPONSE LIMITED The controller is using the high limit for proportional band or reset. Check tuning constants.
IB-23C650 TUNING Autotune Completion Autotune will generally result in successful calculation of tuning constants. When a completely successful autotune cycle is completed, the controller will be in the automatic mode using the newly calculated tuning constants, and will display the process variable and the controller set-point. If autotune was activated while in the automatic mode, or in manual without set-point tracking, the set-point will be at the same value it was at prior to autotune.
IB-23C650 TUNING Cancellation During Execution Press the manual key to cancel the autotune cycle during execution by the controller. This will prevent completion and will place the controller in the manual mode. The controller output will be changed to the starting output value prior to the execution of autotune. If the controller is in automatic mode when the cancellation is executed, the controller will cancel the autotune cycle and will change to manual mode.

IB-23C650 RAMP/SOAK OPERATION RAMP/SOAK OPERATION DESCRIPTION OF RAMP/SOAK PROFILE The Ramp/Soak Profile option complements any type of control implementation by adding a ramp/soak set-point profile with up to 10 ramp or soak segments. The ramp function changes the local set-point up or down at a specified rate. The soak function maintains the set-point at a fixed value for a specified period of time. Figure 19 shows a typical profile and some of its features.
IB-23C650 RAMP/SOAK OPERATION Figure 19.
IB-23C650 RAMP/SOAK OPERATION OPERATION IN AUTOMATIC The ramp/soak sequence is initiated and monitored in the DISPLAYS MENU where the instrument display appears similar to the example below. To access Autotune or remote set-point capabilities, the ramp/soak profile must be turned off. If tune or configuration passwords were configured in the BASE CFG MENU, these codes are required to initiate a reset or segment skip.
IB-23C650 RAMP/SOAK OPERATION After selecting RUN or HOLD at the beginning of the ramp/soak display sequence, scrolling accesses the segment status display as shown below: Segment number Time base Time remaining In this example, 1.4 minutes are left in segment 1 of the profile. The initial value for time remaining in a segment is 0.1 units more than the configured value even though the actual time a segment runs is the configured time.
IB-23C650 RAMP/SOAK OPERATION If the [SKIP] or [RESET] prompts do not appear, a password has been configured in the BASE CFG MENU and is required to access these prompts in addition to making changes in other menus. CONTROLLING RAMP/SOAK PROFILE Control of the ramp/soak profile is accomplished in the DISPLAYS MENU where the ramp/soak functions for reset and skip may be manipulated while ramp/soak is on [RSK] [RUN].
IB-23C650 RAMP/SOAK OPERATION • If the skipped segment is the last segment in the profile and the cycle is configured to repeat, the skip returns the profile to the start of the first segment. This action is the same as a reset except that cycle number is not changed. The controller responds in the manner described for a reset.
IB-23C650 RAMP/SOAK OPERATION Ramp or Soak Hysteresis The hysteresis function provides for setting up a band of process variable values relative to the set-point. For example, a temperature hysteresis value of 10*F provides a band between 290 and 310*F when the set-point is 300*F. The band also applies to the set-point, preventing a profile from starting if the set-point is outside the band.
IB-23C650 RAMP/SOAK OPERATION manual set-point is not at the same value as the ramp/soak profile set-point (the ramp/soak profile is paused at its current set-point value when the controller is put in manual). The switch back to automatic causes the process variable to be under automatic control in response to the ramp/soak set-point.
IB-23C650 TOTALIZER OPERATION TOTALIZER OPERATION DESCRIPTION OF INTEGRATION/TOTALIZATION FUNCTION The integrator/totalizer provides the capability to integrate process signals and display totalized values on the front panel. Signals which have a linear relationship can be integrated and totalized directly. Flow signals, which are proportional to differential pressure, require the application of square law linearization which is available as a standard function.
IB-23C650 TOTALIZER OPERATION • Scale Factor This feature allows custom scaling of the totalized value. The reciprocal of the entered value (0.001 to 30000) is used as the totalizer scale factor. OPERATION OF CONTROLLER USING TOTALIZATION The operating procedure for integration/totalization is very similar to that of a controller without totalization enabled.
IB-23C650 TOTALIZER OPERATION Preset Value The preset value is the number from which the totalizer starts counting after a wrap or when the totalizer was first initiated. This value is typically 0. Leading zeros are not suppressed. Predetermined Count The predetermined count is the value at which the totalizer resets and starts over when the wrap function is enabled. If a totalizer event relay is enabled in the RELAYS MENU, the relay transfers to signal that the predetermined count has been reached.
IB-23C650 TOTALIZER OPERATION EXAMPLES OF TOTALIZER COUNT FACTORS There are three configurable factors that affect what one totalized count equals in actual engineering units and how quickly the totalizer counts. The first factor is the engineering units configured in the TOTALIZE MENU. The other factors are the rate (engineering units time base), and the totalizer scale factor. Table 14 and its notes give several flow examples of how these factors affect the totalizer count.
IB-23C650 TOTALIZER OPERATION Table 14. Examples of Totalizer Count Factors Actual Flow at 100% Configured Engineering Units (Note 1) Scale (Disp. Mult.) Configured Rate Scale Factor (Note 2) 1 Count Equals (Note 3) Minimum Rollover Time (Note 4) 6,000,000 gal/day 0 to 4167 gal/min x1 MIN 1 1 gal 40.0 Hrs 6,000,000 gal/day 0 to 416.7 gal/min x 10 MIN 0.1 1 gal 40.
IB-23C650 TOTALIZER OPERATION 2.) Configured scale factors are 0.001 to 30000. The unscaled total is divided by the configured scale factor to get the scaled count. 3.) The calculation for 1 count is based upon the display multiplier and scale factor. Since the scale factor is a divisor of the count, it has an inverse effect on the display multiplier when calculating count and so a multiplier of 10 times a scale factor of 0.1 equals 1, or 1 count equals 1 unit. 4.
IB-23C650 RATIO BIAS CONTROL RATIO BIAS CONTROL RATIO BIAS CONTROLLER Ratio bias control systems maintain two or more process variables at a predetermined relationship, or ratio. In a ratio bias controller the ratio or bias value is applied to the remote set-point input before the set-point is passed to the PID algorithm. The output of the PID algorithm controls the dependent flow valve in order to maintain the correct ingredient relationship.
IB-23C650 RATIO BIAS CONTROL The independent (wild) flow changes from time to time, and in order to maintain the correct proportions of the blend the other (dependent) flow must be controlled to change in a like manner. The dependent flow must change in the same relationship, or ratio, to changes in the independent flow. The wild flow is not necessarily uncontrolled; it is only wild insofar as the ratio system is concerned.
IB-23C650 RATIO BIAS CONTROL correct ratio value. When the streams do not have the same flow range, the variables must be expressed in engineering units to obtain the correct flow and signal ratio values. Most applications require direct ratio; the dependent variable increases as the independent variable increases. If the signal representing the variable is not linear, it can be linearized using the square root extraction function.

IB-23C650 RATIO BIAS CONTROL A typical A/M Ratio Station application where a plant master steam flow controller provides an input to two boiler masters (A/M ratio stations) is shown in Figure 25.. Each of the two A/M Ratio Stations receive the same process signal from the plant master but their outputs to the combustion control system are different due to different ratios applied to their common process inputs. This is done to balance boiler loading in an effort to optimize boiler efficiency.
IB-23C650 RATIO BIAS CONTROL Instrument Set-up To implement an A/M Ratio Bias Station, enter into the BASE CFG **MENU**, Table 1, and enable A/M Ratio Bias Station at the RAT BIAS ENABLE prompt. If the ratio or bias value is to come from an external source, input two must also be enabled. Configure the station using the RAT BIAS **MENU**, Table 7. The station type can be designated as ratio only, bias only or both ratio and bias.

IB-23C650 TIME PROPORTIONING CONTROL TIME PROPORTIONING CONTROL DESCRIPTION Time proportioning control permits PID control to be used in applications where the control element is an on/off device. The control output is provided by a mechanical SPDT relay. The local set-point and manual control adjustments are made using front panel keys. Process and set-point values are displayed in engineering units, and the calculated output is displayed in percent of output span.

IB-23C650 CURRENT PROPORTIONING CONTROL CURRENT PROPORTIONING CONTROL DESCRIPTION The controller provides an adjustable dc current output signal for current proportioning (analog) control applications. The maximum output load is 1000 ohms for 20 mA and 400 ohms for 50 mA. Control adjustments, displays, and calculated outputs are similar to the time proportioning controller. The calculated output goes to the output driver which generates the current output signal.

IB-23C650 POSITION PROPORTIONING CONTROL POSITIONING PROPORTIONING CONTROL DESCRIPTION Positioning proportioning control permits PID control to be used in applications where the control element is an on/off positioning device such as a motorized valve. The controller output is provided by two SPDT relays. One relay actuates opening of the valve, and the other closing of the valve. Positioning proportioning control requires the option board to receive the valve position feedback.
IB-23C650 POSITION PROPORTIONING CONTROL Reasonable values for Position Proportioning Deadband and Preact can be determined using the following procedure. 1. Perform the valve calibration in the BASE CFG MENU. 2. In the TUNE MENU, set the controller gain to 0.1, Reset to OFF. and Preact to 0. Due to the very slow control action with these settings, valve position can now be read by switching to Auto and quickly observing the output display.
IB-23C650 DIAGNOSTICS DIAGNOSTICS INPUT FAILURE AND POWER FAILURE DETECTION The fault detection level for volt inputs is determined by the percent of volt input span value entered in the INPUTS MENU. If there is a process input signal failure, the controller responds as follows: • If the recovery option is manual, the controller in the automatic mode is forced to manual with local set-point and the output value is switched to the fault output value.
