Notes: With extension cables Without extension cables For ease of connection, especially when using cable trunking, all the terminals are designed to accept wires from the left (when looking from the rear of the unit). If using a pre-wired, 2-wire Pt100 RTD, without connecting extension cables, a link should be added between terminals 9 and 10. If using extension cables, a third wire should be added from point C, one of the joins, as in the diagram above and all three wires should be the same gauge and length. If a simple link is added between terminals 9 and 10 in this case, no compensation for lead length will be applied. As there is no fuse inside the temperature controller, it is recommended that one is provided in the external wiring to the power supply terminals. The sensor wires should not be run adjacent to an AC power supply or the wires to the power supply terminals. When using the relay contact output version it is recommended to provide an auxiliary relay to protect the contacts of the temperature controller's built-in relay, even if the intended load capacity is smaller than that of the built-in contacts. For ease of replacement without disconnecting the wiring, or to gain access to the internal programming switches, the unit can be withdrawn from the housing by pressing the release lever under the bezel and pulling firmly, holding the indents in the top and bottom of the bezel.

The following are set internally: Multi-Sensor Input - 8 Types Selectable The FCS can be user-selected for any of the following sensors: Input Rated scale K -200 to 1370C -320 to 2500F J -200 to 1000C -320 to 1800F R 0 to 1760C 0 to 3200F B 0 to 1820C 0 to 3300F PL-II 0 to 1390C 0 to 2500F N 0 to 1300C 0 to 2300F DIN Pt100 -199.9 to 850.0C -199.9 to 999.9F J Pt100 -199.9 to 500.0C -199.9 to 900.0F Control Action - 4 Operating Modes The FCS can operate in four user-selectable control modes: Adaptive Fuzzy-logic Self Tuning PID In this mode, tuning is performed automatically if the setpoint is changed, if hunting (oscillation) occurs, if an offset is introduced or any deviation occurs due to external influences. In this way, the optimum P, I, D and ARW values are always used for initial ramp-up, normal level control or deviations from normal. PID with Autotune The P, I and D values can be manually set through the front keypad or the autotune can be activated to calculate and program them automatically, together with the ARW. The FCS has several pre-programmed algorithms within its microprocessor and chooses the most suitable one to calculate the values according to when the autotune is activated. For example, if autotune is started when the system is first turned on, an algorithm is chosen to set the P, I and D values that give the minimum overshoot. If the autotune is started when approximately level control is achieved, a different algorithm is chosen to ensure that the most accurate, stable temperature is maintained. The autotune is activated through the front keypad. PD control with reset function PD control can be selected, e.g., in low thermal-mass systems where an integral function can cause overshoots and oscillations. The inherent offset between PV and SV caused by PD control can be eliminated by the reset function which is selectable in 0.1C or F increments. The reset value can be adjusted via the front keypad. On/Off Control with Adjustable Hysteresis If On/Off control is required, the hysteresis can be set in 0.1C or F increments up to 100.0C or F via the front keypad. Heating or Cooling Operation According to the process required, heating or cooling modes can be selected.

The first eight alarm types are deviation alarms. The alarm turns on if the PV (Process variable) deviates from the SV (Setpoint value) by the amount programmed in the alarm, e.g. if a High Limit Alarm is set at 10C and SV = 40C, the alarm turns on when PV rises above 50C. If the alarm is set at -10C and SV = 40C, the alarm turns on when PV rises above 30C. In the four absolute alarms, the actual value of alarm required is programmed, e.g. to alarm at PV=50C, the alarm should be set at 50C. The standby function prevents the alarm from registering if an alarm condition exists when power is initially applied to the controller. This also happens if the setpoint value, SV, is changed to a level which places the current PV into an alarm. When PV has moved out of the alarm level into the normal control area, then any further alarms will be registered. The alarm function is set using internal switches, but the actual value at which the alarm occurs is programmed via the front keypad. Features programmed using the front keypad 3 Levels of Keypad Security Locking To prevent unauthorised modifications to the programming, one of three levels of keypad security locking can be set, to give partial or no access to change the parameters: Level 1 - No setting values can be changed. Level 2 - Only the setpoint can be changed, all others are locked. Level 3 - All setting values can be changed temporarily. When the power is turned off and on again, all settings return to their former values. Adjustable Setpoint Limits The setpoint can normally be programmed within the full range which varies according to the chosen sensor, e.g. -200 to +1370C for type K thermocouples. The upper and lower limits can be restricted to prevent unauthorised or accidental changes beyond these points. % Output Power Display The FCS normally shows the actual process temperature on the PV display and the required setpoint on the SV display, but can be programmed to show the equivalent output power in % on the SV display if required with a resolution of 0.1%. The decimal point flashes as a reminder that it is not a setpoint. This value reflects the ON time of proportional control as a percentage of the total cycle time for the relay and voltage output models, or the mA output as a percentage of full scale for the current output model. PRICE INFORMATION AND ORDERING FCS-13A Features programmed using the front keypad (continued) Wide Alarm Setting Adjustment The setting values of the two alarms are programmed independently and are variable over the full scale span, e.g. for type K thermocouples: Deviation alarms 200C or 200F Absolute alarms -200 to +1370C or -320 to +2500F Adjustable Alarm Hysteresis The hysteresis between the points at which the alarm turns on and resets can be adjusted in 0.1C or F increments between 0.1 and 100.0C or F. Control Output Off If the control is required to stop, or one of several FCS models in a process is not used, the control action can be turned off, with the PV display showing `OFF' as a clear indication. This setting is retained, even if power is turned off and on again, until it is cancelled. Sensor Correction (Input Shift) This function can be used when a sensor cannot be located at the ideal position for control and is placed where the temperature may deviate from that in the ideal position. Also, when using several temperature controllers, this function can be used to correct the apparent temperature difference due to the tolerances of the sensors and the controllers. PV Filter Time Constant Setting If the PV is found to fluctuate due to external disturbances to systems with short time constants then the PV filter feature of the FCS can be used to slow down the response of the whole system (not just the display). Variable Reset in PD Control If the FCS is set for PD control action, a reset function is available to correct the inherent offset associated with this form of control. This is programmable in 0.1C or 0.1F increments. Reset applied Setpoint value Offset is corrected automatically Wide Adjustment of P, I and D Values P - Proportional Band I - Integral time D - Derivative time Offset Temperature 0.1 to 100.0% 1 to 3600 seconds 1 to 3600 seconds Time Fully Variable Proportional Cycle Proportional Cycle 1 to 120 seconds Other features Warm-up Indication When power is first applied to the controller, the PV and SV displays show the type of sensor selected, C or F selected and the scale maximum value in C or F accordingly for approximately 2 seconds, as shown in the table below: FCS-13A Other features (continued) Fast Sampling The sampling period is how often the temperature of the process is measured and the display updated. The FCS has a sampling period of 0.125 seconds, four times as fast as conventional controllers for closer process control. Sensor Break/Overscale/Underscale Indication If the sensor breaks or burns out, or the input temperature exceeds the scale maximum value +5% of the scale span, the PV display flashes and the control output turns off. At the same time, the A2 alarm turns on, e.g. for type K, 1370+(5% x 1570)=1448.5C. If the input temperature falls below the scale minimum value -1% of the scale span, the PV display flashes and the control output turns off, e.g. for type K, -200 - (1% x 1570) = -215.7C. Heater Burnout The FCS is available with heater burnout detection as an optional extra which must be specified at the time of ordering. This function monitors the current through the load heater elements via a current transformer. If the current falls below a userprogrammed level, alarm A2 turns on and latches and will only be reset if the fault is rectified and then the power to the FCS turned off and on again.
