General SAFETY, EMC AND GENERAL INFORMATION Please read this section carefully before installing the controller This controller is intended for industrial temperature and process control applications when it will meet the requirements of the European Directives on Safety and EMC. Use in other applications, or failure to observe the installation instructions of this handbook may impair the safety or EMC protection provided by the controller.
General Without change of the hardware the main process variable input of the instrument can be configured to suit various thermocouples and resistance thermometers, (PtlOO). Recalibration is not necessary for this procedure. Signals up to 25V can be accommodated by using input adapters in the linear input option. Linearisation is scaleable within the display range of -999 to 9999, with tenths display resolution. The controller is also equipped with a ramp to setpoint function.

Before wiring, verify from the instrument label (on the side) which options have been built into the instrument and how the instrument is configured. The terminals at the rear of the instrument are numbered from 1 to 20.
Installation will read the line voltage even though the output is off. This does not indicate that the output is faulty. Such a test should only be carried out when the output is loaded appropriately.
Installation output 1 Output 1 can be fitted with four output module types: triac (Tl), relay (Rl), logic (Ll) or DC (Dl). Check the relevant code on the instrument label. The external connections depend on the type of output module installed. If output 1 is configured as time proportioned with power feedback, the mains supply of the instrument must be connected to the same Live as the load supply.

Operating structure The operation of the instrument is structured on two access levels. Within these levels, three operating modes and four control algorithms with their parameters may be selected. Operator level: The operator level is intended for normal, everyday operation of the controller at the plant, The modifiable parameters on this level are fixed by the commissioning engineer in the ACCESS menu. Configuration level: The configuration level is intended for commissioning the instrument.
Operation Operating modes The controller can function in three different operating modes. In automatic or closed loop, the output of the controller is determined by the control algorithm. In the base condition, the process value and the setpoint appear on the LED display. The setpoint is modified by the raise and lower buttons. Changeover to manual is through the A/M button (if not locked out, see section 5.4).
Oaeration Front panel identification The instrument is operated and also configured by means of four pushbuttons and displays on the front fascia (Figure 5.4.1). Displays: The upper display indicates the measured value when in the base condition. On selecting a parameter, the appropriate parameter abbreviation appears. If one of the configured alarm conditions occurs, the display flashes. The lower display indicates the setpoint when in the automatic mode and the output level set when in the manual mode.

Operation operating mode to the manual mode. Depressing the button again returns the controller to automatic. The changeover is bumpless, the output level at the time of the changeover is transferred into the required operating mode. If the instrument is configured as an ON/OFF controller, the output level can only assume one of two values (0 or 100%). This button can be locked out in the configuration level, so that the instrument remains in the operating mode chosen before lockout.

Operation Alarms Two alarm outputs may be installed in the controller. Three different types of alarm can be set up with these alarm outputs by configuration: . Full-scale high alarm (H AO) . Full-scale low alarm (L AO) . Deviation band alarm (d AO) In the alarm condition, the alarm outputs fitted and configured with the appropriate modules are energised. Alarm output 1 and alarm output 2 possess different characteristics.
Operation Alarm output 1 (fitted with the appropriate module) operates as the collective alarm for all configured alarm types, i.e. it operates if at least one of the configured alarm conditions occurs. The function of the alarm output can be configured for each type of alarm as ‘latching’ (LAt), ‘non-latching’ (nLAt) or as ‘not active’ (OFF). If the appropriate alarm type is configured as non-latching, it is then a ‘soft-alarm’ in the instrument.
Operation the nearest EUROTHERM branch for inspection. Under no circumstances should the faulty instrument be used.
Configuration CONFIGURATION LEVEL, OPERATOR LEVEL Configuration link/switch There are over 30 parameters maintained in the non-volatile memory of the instrument. These parameters are pre-set according to the product code and corresponding standard values, but can, however, be modified at any time by commissioning staff allowing for the available and externally connected hardware.
Configuration R Configuration Link open = operator level M Link closed = configuration level OP1 OP2 Figure 6.1.1 Configuration link/switch Hardware configuration It is important to note in the configuration of the instrument that the configuration parameters possible for an output (OP 1, OP 2 or AL 1) depend on the output module installed. Depending on the output module, only certain configuration values may be selected. Figure 612.
Configuration Parameter list All parameters available in the instrument are listed on the following pages. The sequence of parameters corresponds to the sequence in the instrument, as it appears after pressing the PAR button. Some parameters influence the appearance, and similarly the disappearance (HidE), of other parameters, e.g. the cool cycle time is hidden if no cool output channel is configured. Other parameters depend on the firmware options of the instrument.

Configuration Pre-configuration, parameter setting A large number of parameters are installation-dependent, and as such only need setting once before commissioning. This setting should take place before connecting the instrument to the plant, e.g. at a bench. In addition, these parameters should, for security reasons, be removed from the operator’s ACCESS menu (HidE). WARNING Never configure the instrument while it is controlling a process.
Configuration To adjust cutback, both parameters are set in the first instance to match the proportional band. Thus cutback is cancelled (switched off). The data is always in display units and must therefore be recalculated in percentage for proportional band: Hcb=Lcb=Pb for Pb in units: H cb = L cb = Pb(%) x measurement range/100 for Pb in %: Now the process is started up with a large control deviation and the degree of over- and undershoot is registered.
Calibration Parameter access protection This menu defines the parameters which are modifiable at the operator level. The menu is only available when the configuration link/switch is closed. Here, each parameter is defined as to whether at the operator level it is: . ‘readable and alterable’ (Altr) ‘readable only, not alterable’ (rEAd) . ‘hidden’ (HidE). With the configuration link/switch closed, scroll down to the mnemonic ACCS using the PAR button.

Depress ‘lower’ button until desired access appears 5. Depress ‘raise’ button to advance to next parameter Assign access for all parameters Figure 7.1 .
Calibration Factory calibration is stored in the non-volatile memory of the instrument, and can be retrieved at any time without the aid of calibration sources. For factory calibration, follow the instructions given in Figure 7.2.1, the instrument must be set to configuration mode by closing the configuration link/switch. Factory calibration must not be attempted while the instrument is controlling a process. Field calibration of the instrument should only be performed by trained and qualified personnel.
Calibration Depending on the measurement range, different reference voltages must be calibrated in the instrument. The necessary references are listed in Figure 7.2.2 and must be calibrated in the sequence given in the table. REFERENCE 1. 2 0 . 0 0 m V 2. 5 0 , 0 0 0 m V 3. CJC 4.

Programmer/Controller PROGRAMMER/CONTROLLER Programmer/controller - Function Models 808 and 847 with option QLPS contain an in-built setpoint generator in addition to the controller function. This setpoint generator can produce a temperature/time profile with four segments. When the program is running, the current setpoint from the setpoint generator is fed to the control algorithm. The current setpoint is continuously shown on the lower display.
Programer/Controller the ramping rate in units per minute (0.01 to 99.99), parameters L1 and L2 the appropriate target setpoint in display units (adjustable over the configured measurement range, but not restricted by SP H and SP L). The starting setpoint for ramp 1 is always the current measured value (servo). Even during a program repeat, the starting setpoint is always set equal to the current measured value at the moment of reset.
the program on the current setpoint. From the Hold state, the program can be continued (run) or reset (IdlE). Setpoint Setooint >I Figure 8.2.1 Programmer/controller states Programmer/controller - Holdback The holdback state (Hb) is a special case of Hold. It is activated of its own accord by the programmer/controller and cannot be selected by the user. The Hb parameter allows the user to set the difference tolerated between the current setpoint and the actual value while the program is running.
Programmer/Controller Setpoint/actual value Process value Time Process value oscillates during dwell period: HOLDBACK stops the time base when process value outside holdback band Figure 8.3.1 Holdback Programmer/controller - Setpoint programming The state of the programmer can be modified in three ways. All three have the same priority and the last action from any of them is acted upon: .

LED on *run Hold or Holdback . LED flashing Programmer/controller - Parameter modification Modifications to the parameters specific to a particular program are differently interpreted according to the state of the programmer/controller.
Programmer/Controller Ending a program At the end of a program, the programmer/controller returns to the IdlE state and switches back to the normal control setpoint (SP). According to the target setpoint of ramp 2 and the normal control setpoint, different conditions ensue. The setpoint can be modified as in normal closedloop operation whilst the program is running and influences the end of the program. Figure 8.5.1 shows a combination of all possibilities.
Programmer/Controller Program recovery following loss of power All the instrument parameters are stored in non-volatile memory. When power is lost, the current point in the program is also stored in the memory. When power is restored, the programmer/controller resumes the program in the appropriate segment at the point reached at the moment of interruption, as soon as the process value re-enters the holdback band. Setpoint/actual value Process value Time Power failure A.
Self-tuning SELF-TUNING Self-tuning - General 808 and 847 controllers have in-built self-tuning as a standard feature, which can be activated by the user on demand. According to a special procedure, the instrument examines the process reaction curve and calculates by means of a complex computer algorithm the optimum control parameters, using the data measured during the procedure. The parameters thereby obtained after successful tuning are automatically set into the instrument.
Self-tuning band for the cool channel. Here, too, a correct setting of rEL.C is necessary before activating self-tune. Self-tuning - Activation Self-tuning can be activated under the following conditions: Operator level (not in configuration level) . Automatic operating mode (closed loop) . PID control algorithm (Pid, r SP, or Prog) In the following circumstances, self-tuning is halted or overridden: Tuning is halted when the controller is switched over from automatic to manual.
Self-tuning Tune from ambient: The desired setpoint for tuning can be adjusted with the raise or lower buttons for about one minute. During this time the output level is reset to zero. Also at this time the influence of adjacent zones on the specific zone is observed and compensated for in the algorithm. After this the actual tuning operation begins, the instrument commands heat (if setpoint is greater than actual value) or cool (if setpoint is smaller than actual value) with maximum output strength.
Self-tuning Process value Process reaction curve output Tune from ambient - cool down Figure 9.3.
Self-tunina Tune from setpoint: After initiating a self-tune from setpoint, the output power is fixed for one minute at the original value. If during this time a new setpoint is set, the instrument automatically switches to tuning from ambient. Again at this time, the influence of adjacent zones on the specific zone is observed and compensated for in the algorithm. After this, both outputs are switched off for a short while and the process reaction curve is observed.

Self-tuning Self-tuning - Abort conditions In some cases, the self-tune routine aborts spontaneously due to external influences in the process being tuned for by the instrument. In a heat-only controller, this is the case when, for example, through the influence of an adjacent zone, the process is heated up to the setpoint without its own heat source. The tuning algorithm recognises such a case and aborts the tune of its own accord after a time (depending on the process reaction).
