Notes:
- 4-20mA is the standard factory setting for the input signal of this PCU.

Depending the system environment a suitable output (feedback) signal can be selected by adj
usting the SW8 DIP-switches as follows:
Note: 4-20mA is the standard factory setting for the output signal of this PCU.
CAUTION: “(1) Selection of input signal” ZERO SWITCH (SW7.3) Usage Notes
D) Deadband Setting
- Max. allowable value of actuator position error by input command signal.
- Min. variation range of the input command signal to start operating the actuator.
- Range of DEAD BAND setting: 0.3 ~ 7.5% (setting in 16 steps)
① Step 0 : 0.1% increase per step (0.3% ~ 0.7%)
② Step 1 ~ 4 : 0.2% increase per step (1.0% ~ 1.8%)
③ Step 5 ~ 15 : 0.5% increase per step (5.0% ~ 7.5%)
④ Factory setting : “2”
- In case the DEADBAND is set too narrow, the actuator may run back and forward repea
tedly not finding the target position. This is called as HUNTING.
- DEADBAND should be properly adjusted in order to prevent HUNTING.
