EVENT Function

This controller provides a maximum of 3 EVENTs (EV1~EV3) for respectively setting EV functions as shown in the following Table <1>. For example, if EV1 is used for Run/Stop selection, when the controller is set to RUN status, if terminals in the Option1 slot are open, the controller is in RUN status; if terminals in the Option1 slot are shorted, the controller switches to STOP status.

Run/Stop: This function switches the controller between RUN and STOP status.

SV 1/SV 2: This function selects SV 1 or SV 2 as the active setpoint.

Auto/Manual: This function selects PID and Manual control.

¾Insert EV1, EV2 PCB to Option1 or Option2, or insert hardware with a built-in EV3 function

¾Set EV functions as listed in Table <1> EVT Function Setting by parameters , , inRegulation Mode. Note: Selection of “Evt‘x’” items must match with the inserted PCB; if only Option1 is inserted, then only “Evt1” will be displayed.

Limits of temperature ranges

Different input sensors have different application ranges (e.g.: J type factory setting is -100 ~ 1200), adjust parameters

(upper

limit) /

(lower limit) in Initial Setting Mode.

 

If lower limit is altered to 0 and upper limit is altered to 200, the limit function will be enabled in the following conditions:

 

¾When setting the SV value, the limits may set for 0~200

¾In ON-OFF, PID, FUZZY and Self-Tuning control conditions, the control output will be forced to shut off if the PV value exceeds the upper/lower limit. (Alarm output is still normal)
