If there is a lot of noise in the power line, insert an insulating transformer into the primary side of the line and use a line filter (recommended part: ZAC220500U from TDK) on the secondary side. As a countermeasures against noise, do not place the primary and secondary power cables close to each other. 2) For thermocouple input, use shielded compensating lead wires for wiring. For RTD input, use shielded wires that have low conductor resistance and cause no significant differences in resistance between the three wires. The cables to be used for wiring, terminal specifications, and recommended parts are as shown below. 3) Control output relays may be replaced. However, because they have a life of 100,000 times that of the resistance load, use auxiliary relays to turn on/off a load. 4) The use of inductance (L) loads such as auxiliary relays, motors and solenoid valves causes malfunction or relay failure; always insert a CR filter for use with alternating current or a diode for use with direct current, as a spark-removal surge suppression circuit, into the line in parallel with the load. 5) When there is possibility of being struck by external lightening surge, use the arrester to protect the instrument.

The type of control output can be set/changed using the parameter “OT”. At this point, the controller must be wired correctly according to the selected type of control output. Check the wiring first if the controller provides no control output. To do this, refer to “6. Terminal Wiring Diagrams,” in Installation User’s Manual . With the parameters “OH” and “OL”, it is possible to set/change the high and low limits of control output. The control output may not change at all, however, because of restrictions on these parameters. Also check the restrictions on these parameters. • The control output can only be changed when the controller is in the MAN mode. If the MAN lamp is off (i.e., the controller is in the AUTO mode), you cannot change the control output using key operation. Correct errors. Is key lock enabled? Yes No communication capability. No Does the code include a communication option? Check the communication-related parameters. ● The control output does not change soon after the target setpoint SP has been changed. • If this happens, check the setpoint of the parameter “C.MD”. In cases where fixed-point control is selected as the PID control mode (C.MD = 1), tracking based on the I-term works to prevent the control output from changing suddenly even if the target setpoint SP is varied. The control output therefore may appear to be working incorrectly at first; however it gradually adapts itself to the new target setpoint. Check communication wiring.

The control output begins with the preset output value. • The UT350/UT320 controllers have a universal input. The type of PV input can be set/changed using the parameter “IN”. At this point, the controller must be wired correctly according to the selected type of PV input. Check the wiring first if the controller fails to show the correct PV. To do this, refer to Initial Settings User’s Manual . With the parameters “RH”, “RL”, “SDP”, “SH” and “SL”, it is possible to scale the input signal and change its number of decimal places.

If the temperature difference target setpoint before switching is greater than the target setpoint after switch70°C/min ing, the controller operates according to the settings of the Setpoint Ramp (140°C/2 min) rate of Down (DNR) and Ramp Time Unit (TMU) parameters. The figure on the 1.SP=500°C temperature change right shows an example when the Target Setpoint Number (SP.NO) param2-minute interval of eter is switched. The 1.SP and 2.SP parameters are set to 500°C and 640°C, temperature rise respectively. Thus, there is a temperature difference of 140°C between the Switching from 1.SP to 2.SP parameter 1.SP and 2.SP parameters. This example shows how the temperature is changed by as much as this temperature difference over a period of two minutes. In this NOTE example, the UPR parameter is 70°C and the TMU parameter is 1 minute. When using target setpoint ramp setting function, PV tracking works Setting Method: [1] Set the Zone PID Selection (ZON) parameter to “ON”. [2] Define a reference point. When using two zones, define only reference point 1 (1.RP) between the minimum and maximum values of the PV input range. When using three zones, define reference points 1 and 2 (1.RP and 2.RP) in the same way as noted above.

A cycle time refers to one period consisting of on- and off-state time lengths. The ratio of the on-state time to the off-state time differs according to the value of the control output. The figure on the right shows on-to-off time ratios of the control output when the cycle time is set to 10 seconds. Setting a shorter cycle time allows the controller to perform elaborate control at short time intervals. This significantly reduces the on- and off-state times, however it shortens the service life of a relay.
