However, when power supply variations are large, set the alarm to a slightly smaller value. In addition, when two or more heaters are connected in parallel, set the alarm to a slightly larger value so that it is activated even with only one heater is broken.

CWhen the heater break alarm set-value is set to “0.0" or the current transformer is not connected, the heater break alarm is turned ON. CUsually set the set-value of the LBA to a value twice the integral time (I). OSet data locking procedure This controller is provided with a set data locking function which disables each set-value change by the front key and also the auto-tuning function.

Thus the set data 1.Do not change the upper 2 digits “01" of the set-value, as it may cause malfunction. 2.Checking each set-value is possible during data locked. O CDo not use the auto-tuning function in a control system where hunting causes trouble. In this case, set each PID constant appropriate to the controlled object. CConnect the input signal wiring, and then turn ON the power. If the input signal wiring opens, the controller judges that input is disconnected to cause the upscale or downscale of measured-value display. Upscale ............... For TC or RTD input Downscale .......... For TC (To be specified when ordering) C more, the controller performs the same operation as that at the time of power-ON after power recovery. (This applies only when alarm action is turned OFF). CWhen the set-value (SV) is changed during progress in the auto-tuning function, suspend the auto-tuning to perform PID control using the values before auto-tuning start. CWhen the auto-tuning function is suspended halfway, no values of PID and control loop break alarm are changed. (The value before auto-tuning function start is maintained). -8- No influence is exerted upon the controller for power failure of 20 msec. or less.
