LOW voltage field wiring

The MV4000 is powered from the air conditioners that it is controlling, 24 VAC (18-32V) low voltage only.

Circuitry in the MV4000 isolates the power supplies of the two air conditioners so that no back feeds or phasing problems can occur. Additionally, if one air conditioner loses power, the MV4000 and the other air conditioner are unaffected and will continue to operate normally.

Connect the low voltage field wiring from each unit per the low voltage field wiring diagrams in Section on “Controller Wiring”. note: Maximum of 18-gauge control wiring should be used. Using heavier gauge wiring can create excessive stress on the control board as door is opened and closed. Create a wiring loop so the door can open and close without stressing terminal blocks.

controller grounding

A reliable earth ground must be connected in addition to any grounding from conduit. Grounding lugs are supplied for this purpose.

controller power-up

Whenever power is first applied to the controller, there is a twenty (20) second time-delay prior to any function (other than display) becoming active. This time-delay is in effect if the controller On/Off button is used when 24VAC from air conditioners is present, and also if controller is in “ON” position and 24VAC from air conditioners is removed and then restored.
