FIG. 10 — ML7984 WIRING WITH 135Ω (SLIDEWIRE) CONTROLLERS
Allow 0.5 amps maximum for each device.
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) or Reverse acting function (actuator stem moves downwards with signal
increases).
*Series 90 (mech/electronic) operation can be reversed without changing wiring by using DIP switch #3
(opposite as shown).
NOTE:
1) Turn power off before setting the DIP switches.
2) For common transformer and common controller application, please consult the factory.
