D750M
CONTROL CARD FOR TWO SINGLE-PHASE MOTORS 230 Vac
The D750M panel features an electronic photocell control system which switches the external
photocell transmitter on and off thereby causing the control unit microprocessor to check wheth-
er the relay switches correctly. If this does not happen, the control unit is automatically blocked

TESTING
When all connections have been made:
All the green LS LED’s must be on (each corresponds to a Normally Closed input).
They only turn off when the commands they are associated with are active.
All the red LS LED’s must be off (each corresponds to a Normally Open input) they only turn
on when the commands they are associated with are active.
