B) Selecting Output Signal (SW8 on PCU-A or SW3 on PCU-D)
User can select different types of output signals by adjusting the DIP switch as follows:
4 - 20mA DC
Output Signal
Switch
Input signal switch No. 3
(PCU-A SW7 or
PCU-D SW2) “ON”
0 – 10V DC
Input signal switch No. 3
(PCU-A SW7 or
PCU-D SW2) “OFF”
2 – 10V DC
Input signal switch No. 3
(PCU-A SW7 or
PCU-D SW2) “ON”
0 – 5V DC
Input signal switch No. 3
(PCU-A SW7 or
PCU-D SW2) “OFF”
1 – 5V DC
Note 1: If not specified, the factory setting of the output signal is 4 - 20mA.
Note 2: If the ELA150~3000, 115/230VAC actuators only will be operated by open and close
commands on terminal 11 and 12, the following procedure must be followed in order to select
the desired feedback signal:
• Select the output signal by adjusting the DIP switches as mentioned in this paragraph.
• Connect the power supply; Neutral on terminal 5 and Live on terminal 13.
• Make a link between terminal 13 and 14 and connect a multi-meter to terminal 17 and 18.
• Push “auto adjust” (red button on the circuit board) for 2 seconds.
• The actuator will now “auto adjust” itself.
• After the adjusting cycle has stopped, remove the link between 13 and 14.
• Now the actuator van be operated by giving the open and close commands on terminal 11
and 12. The feedback signal will be given on terminal 17 and 18.
• The feedback signal however still needs to be checked and if necessary adjusted. Therefor
measure the voltage or current on terminal 17 and 18, while opening and closing the
actuator. If necessary adjust the potentiometers “zero” and “span” on the bottom of the
circuit board until the output values are correct.
