switch, and to the 3-port valve actuating pump would be
connected to the terminals from No. 3 through No. 10.
・Electrical wiring of control signal, alarming signal and etc.
will be connected to the terminals through cord-lock.
・After completion of the wiring, attach the cover firmly to
the original position.
・Twin timer or programmable controller should be prepared in advance separately for the
interval oil shot operation of the pump in the Micron-Lub lubrication unit. (MC9 models
with electrical control circuit are excepted)
