Necessary Conditions for responding to a call
The board can respond to a call when:
•
it is not running and "inspection" manoeuvre.
•
It is not overloaded.
•
None of its photocells or barriers are obscured.
•
It is not in a non-recoverable error mode (see par. 5.2 "Fault table and fault finding").
•
It is not in board or timer/variable-function programming mode.
•
The following leds are on: OK / WD / D1 / D2 / D3.
If the above conditions are satisfied, the system responds to the call by closing the doors (REMP2: red led CP/
CP1) and, once safety chain closure has been verified (REMP2:led D4), it closes the retiring cam, if present
(REMP2: led PAT) and the contactors, in the sequence high speed+up or high speed+down.
The control signals for exciting the drive contactors are output by connector J8 on board MP3, while the red leds
light up on the REMP2, depending on the type of actuation:
