Electronic Series 90
Reverse Acting
For Figures 11A and 11B the following apply:
Power supply provides overload protection and disconnect means.
1
Allow up to 0.5 amps for each device. Actuators and controller can share same transformer providing the VA rating of the
2
transformer is not exceeded and proper phasing is observed. Do not mix a.c. and d.c. power sources.
Do not mix M984/6 or Modutrol Motors with the ML7984 in the same circuitry.
3
Use configuration DIP switches to select device functions: Direct acting function (actuator stem moves upwards with
4 signal increases to 10V/20mA) or Reverse acting function (actuator stem moves downwards with signal increases to 10V/
20mA).
5
Turn power off before setting the DIP switches.
