• If you want to use a Controller with position-proportional control to monitor
the amount of valve opening or perform closed control, connect a potenti-
ometer (PMTR) as shown below.

• For information on the potentiometer, see the manual for the valve you
are connecting. Terminal number meanings are as follows:
O: OPEN, W: WIPE, C: CLOSE
The input range is 100 Ω to 2.5 k Ω (between C and O).
• To use the event inputs with the E5AR, connect event inputs 1 and 2 (EV1
and EV2) to terminals K1 to K3 as shown below.
• To use the event inputs with the E5ER, connect event inputs 1 and 2 (EV1
and EV2) to terminals E1 to E3 as shown below.
