Selecting an EIA/TIA-232 to EIA/TIA-485 Converter 12 V GN ( GND dc) TD D ( TD B) (A ) When choosing an EIA/TIA 232 to 485 converter, look for one with the following features: Two-wire capability EIA/TIA-485 can be implemented as a two-wire system or a four-wire system. Most Watlow controllers, including the Series SD, use two-wire communications when working with EIA/TIA-485. The converter selected must have a two-wire mode. Some converters can only be used in a four-wire mode.
Ethernet Gateway The EM00-GATE-0000 is a bridge that allows up to 32 Watlow controllers to be directly connected to an Ethernet network. The gateway provides a bridge for Modbus messages between the Ethernet bus and EIA485 or EIA-232 links. The Gateway supports full product configuration monitoring and configuration of runtime parameters via MODBUS TCP over TCP/IP using a software package such as Watlow’s WATVIEW™. The Series SD can be configured using WATVIEW with or without the EM Gateway.

Saving and Restoring User Settings 1. Be sure all profiles are programmed as desired. Recording setup and operations parameter settings for future reference is very important. If you unintentionally change these, you will need to program the correct settings back into the controller to return the equipment to operational condition. After you program the controller and verify proper operation, use [USr;S] to save the settings into a special section of memory.
change the selected parameter in the top display. If you do not want a parameter to appear for that location, select [nonE]. To change the other 19 selections, press the Advance Key ‰ to select a place in the page, [``P1] to [`p20] ( [~P23] for the profiling version), in the bottom display and use the Up ¿ or the Down ¯ key to change the parameter selected in the top display. Changes made to the Operations Page will persist until changed by the operator or defaulted by full defaults or user defaults.
over which the controller will continuously tune the control parameters, or enter a fixed value. This parameter is provided for use only in the unlikely event that the controller is unable to automatically tune and stabilize at set point. This may occur with very fast processes. In that case select a large value, such as 300. Otherwise, leave this parameter set to auto.
Access Lockout The user’s access to the Operations Page can be controlled through the [`LOC] parameter. The [`LOC] parameter appears at the end of the Setup Page. It does not affect the Setup, Factory or Programming Pages. [```0] All the Operations Page parameters may be viewed or changed. Full access to profiles on profiling version. [```1] The set point, process value, auto-manual selection and alarm settings are the only visible Operations Page parameters. Set point is adjustable in this level.
High Scale and Low Scale Auto (closed loop) and Manual (open loop) Control When an analog input is selected as process voltage or process current input, you must choose the value of voltage or current to be the low and high ends. For example, when using a 4 to 20 mA input, the scale low value would be 4.00 mA and the scale high value would be 20.00 mA. Commonly used scale ranges are: 0 to 20 mA, 4 to 20 mA, 0 to 5V, 1 to 5V and 0 to 10V.
mode and it is off while in the auto mode. For the profiling controller, the letter P appears in the left side of the lower display followed by the manual % power set point value. For example, [P~75] indicates the profiling controller is in Manual Mode at 75% power output. You can easily switch between modes if the Auto-Manual Mode [A-M] parameter is selected to appear in the Operations Page. To transfer to manual mode from auto mode, press the Advance Key ‰ until [A-M] appears in the lower display.
Proportional plus Integral (PI) Control the process temperature to the set point. When the dead band value is zero, the heating element activates when the temperature drops below the set point, and the cooling element switches on when the temperature exceeds the set point. Adjust the dead bands with Dead Band Heat [db;ht] and Dead Band Cool [db;CL] (Operations parameters). The droop caused by proportional control can be corrected by adding integral (reset) control.
[nLF3]) in the Setup Page. 50% would result in an actual output power level of 50%. But if the PID calculated power output is 100%, then the power level will be 70%. Power scaling establishes the maximum power output and the minimum power output. The output power is then linearly scaled within that range. The default values of Output Power Scale Low of 0% and Output Power Scale High of 100% in effect disable power scaling.
ing is done only at the zero cross of the ac line, which helps reduce electrical noise (RFI). Variable time base should be used with solid-state power controllers, such as a solid-state relay (SSR) or silicon controlled rectifier (SCR) power controller. Do not use a variable time base output for controlling electromechanical relays, mercury displacement relays, inductive loads or heaters with unusual resistance characteristics.
Alarm Hysteresis The process temperature has to enter the normal operating range beyond the hysteresis zone to activate the alarm function. An alarm state is triggered when the process value reaches the alarm high or alarm low set point. Alarm hysteresis defines how far the process must return into the normal operating range before the alarm can be cleared. Alarm hysteresis is a zone inside each alarm set point.
RTU protocol to read or write to registers in the controller. See the parameter tables for information about the Modbus registers. These registers contain the parameter values that determine how the controller will function and current input and output values of the system. The address in the tables have been offset by subtracting 40,001 from each one. Two consecutive registers are addressed for 32-bit data types. The first word, or lower register number, contains the two higher bytes.

Advantages of this feature include automated logging of key process variables, increased accuracy and ease of use for recipe or configuration setups, and easier controller data exchange in physically restricting environments, such as semiconductor clean rooms. This feature reduces the use of paper to record instrument information as well as human transposition errors. 7. Start communications with the controller.
Troubleshooting Indication Probable Cause Corrective Action No power. Controller appears dead. No display indication in either window. Power to unit may be off. Fuse may be blown. Breaker may be tripped. Safety interlock door switch, etc. may be activated. Separate system limit control may be latched. Wiring may be open. Input power may be incorrect. Check switches, fuses, breakers, interlocks, limit devices, connectors, etc. for energized condition and proper connection.
Troubleshooting Indication Getting alarm message [A1hi], [A2hi], [A3hi], [A1Lo], [A2Lo] or [A3Lo]. Probable Cause The process value is beyond an alarm set point. Alarm is occurring when it should Alarm settings are incorrect. not. Corrective Action Determine when alarms messages will display and the proper response to an alarm message. Adjust the alarm settings to be correct for the application. Input may be in an error condition. See error messages. Alarm may be latched.
Troubleshooting Error Messages Indication Probable Cause Corrective Action [Er;In] Input Error The sensor may be improperly wired. Sensor wiring may be reversed, shorted or open. The input may be set to the wrong sensor or the controller may not be calibrated. Calibration may have been corrupted. Check sensor connections. Check sensor connections and sensor wiring. Change Sensor Type [`Sen] (Setup Page) to match the sensor hardware. Restore factory calibration.
