INSTALLATION MANUAL
The inspection control is activated when the car top inspection switch is switched from “
NOR
” to “
ISP
” position.
RM
relay is energized and sends the information that inspection control has been activated to terminal
J11/6(RM)
of the board; “HH” signal will appear on board display.
The contactors are controlled by the board
which actuates the control signals received from the inspection control panel as follows:
•
Inputs J7/1
(▼)
and J7/2
(▲)
receives the control signals from the “down” and “up” buttons (if both
signals are present, no control signal is output).
•
The same buttons, via their diodes, terminal 2A or BSQ/BQD and the RM contact, power the safety chain; the
board checks for voltage at input J7/8 (led D3 REMP2) and outputs the close doors signal.
•
When full closure of the safety chain is confirmed via the pick-up point at input J7/10 (led D4 REMP2), the
slide and contactors are activated.
•
Depending on the signals at inputs J7/1
(▼)
and J7/2
(▲)
the board activates the high speed+down
outputs (GV+D) or high speed+up outputs (GV+S) and monitors their excitation and de-excitation as in
normal operation.
•
To prevent repeated jog operation in a single direction of travel and immediate reversal of direction, a delay
of 1 second has been introduced between the release of a button and the response of the board to the next
operation of the same or another direction button.
•
The faults indication is also active during the inspection activity.
•
The run of the car is limited by CRS and CRD mechanical switches or by bistable CRSB / CRDB switches at the
top and bottom floors.
•
Once the inspection is completed, the car, if it has been moved, resets to the lowest floor, or to its former
destination.
