Frame 6B,
MK4 Controls.
ADAC 90RC 250QT
-(Quarter Turn) Electric Valve Actuator (275 ft-lbs)
-Single-phase Motor (cap, limit switches, torque switches)
90CJ-1A
-receives 120VAC from dist pnl,
-sends to 90CJ-1B,
-has off switch
90CJ-1B
-valve controller/brake board,
-120VAC from 90CJ-1A,
-Sends ~10V AND COM to <RELAY 2>
-Takes Run and Dir signals from <RELAY 2> (L60WQRUN, L60WQDIR)
We've had troubles with these boards and our inventory is depleted. Documentation is not much in the manuals for the electrical operation, but it seems pretty straight forward. The MK4 side seems to be working well.
RUN & DIR => CLOSE signal
RUN => OPEN signal
Based on that;
-when both relays are open, there should be 0V from M1 to M3 and 0V from M2 to M3 on the brake board.
-when the RUN relay closes, there should be 120V from M2 to M3 and 0V from M1 to M3 on the brake board.
-when the RUN and DIR relay closes, there should be
0V from M2 to M3 and 120V from M1 to M3 on the brake board.
Currently, on both a "repaired" and a "last in stock" brake board, I have 120V from M2 to M3 and 120V from M1 to M3.
This is true for any input combination. Inputs do make the red light blink on the board.
The results are the same with the motor disconnected.
Motor resistance is a few ohms both M1,M2 to M3 in mid position (no limits made).
I have talked to valve vendors for a replacement setup (valve and/or actuator) but none of the newer options seem to handle the RUN & DIR scheme. I could use relays to turn run and direction into OPEN and CLOSE. But I'm hoping I'm not overlooking something simple.
Do you have experience with this setup and/or any advice that may help?
Have you successfully replaced one of these actuators or actuator/valves with something newer and interfaced it with the RUN and DIR relays?
