Case N°1: actuator starts closing and stops before the close limit switch.
Turn actuator potentiometer progressively to bring the actuator on the close limit
switch, LED on. Turn potentiometer slowly in opposite direction until the red LED
goes off.
Case N°2: actuator starts closing, stops on the close limit switch, and the LED indicating
closing is still on.
Turn actuator potentiometer progressively to off the LED.
10.7

ADJUSTMENT OF 100%

The local/off/remote selector must be on remote position. Move local control switch to position
100% for the actuator to receive an opening command (20mA).
Case N°1: actuator starts opening and stops before the close limit switch.
Turn potentiometer ADJ 100% (adjustment of 100%) progressively clockwise to bring the
actuator on the open limit switch. Turn slowly this potentiometer in opposite direction until
the green LED is switched off.
Case N°2: actuator starts opening, stops on the close limit switch, and the LED indicating
closing is still on.
Turn potentiometer ADJ 100% (adjustment of 100%) progressively counterclockwise
until the green LED is switched off.

SPLIT RANGE

The positioner board can be configured for split range.
Split range means input signals 4-12mA and 12-20mA. The end user signal is normal: 4-20mA.
A first actuator is set to receive a signal from 4 to 12mA and a second actuator is set to receive
a signal from 12 to 20mA. Each actuator receives the signal 4-20mA. The first one opens completely
from 0 to 50% of the signal and the second from 50 to 100% of the signal.
Switches 1 and 2
Move switch 1 to position B for the actuator to receive an input signal 12-20mA.
Move switch 2 to position B for the actuator to receive an input signal 4-12mA.
lector must be on remote position. Move local control switch to position
ve a closing command (4mA).
