For Figures 9A and 9B 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.
In ML7984,“T5” and “W” terminals are connected internally. Device is compatible with 3 conductor wiring.
Use configuration DIP switches to select device functions:
Direct acting function (actuator stem moves downwards with
signal increases to 10V/20mA) or Reverse acting function (actuator stem moves upwards with signal increases to 10V/
20mA).
Always turn power off before setting the DIP switches.
ML7984 will accept 0-10 Vdc control input, but will be at the end of stroke at 2 Vdc.
