FIG. 11 — ML7984 WIRING WITH ELECTRONIC SERIES 90 “SUPERMOD” CONTROLLERS
FIG. 11A — ML7984 WITH COMMON TRANSFORMER,
INDIVIDUAL CONTROLLERS
FIG. 11B — ML7984 WITH INDIVIDUAL
TRANSFORMERS, COMMON CONTROLLER
For Figures 11A and 11B the following apply:
Power supply provides overload protection and disconnect means.
Allow up to 0.5 amps for each device. Actuators and controller can share same transformer providing the VA rating of the
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.
Use configuration DIP switches to select device functions:
Direct acting function (actuator stem moves upwards with
signal increases to 10V/20mA) or Reverse acting function (actuator stem moves downwards with signal increases to 10V/
20mA).
Turn power off before setting the DIP switches.
