Controller block diagram（Refer to the previous page and the final page for wiring）
＊1 The array of the terminal in the above figure is different in sequence order from the actual terminal array.
＊2 0V of the input circuit and 24V of the input/output circuit are all common.
＊3 The input circuit of IN1, IN2, B1 and B2, and the circuit configuration of the output circuit of P0, P1 and P2
are the same circuit configuration respectively.
(1) Remove the panel
①Loose two fixing M3-screws on operation panel and
remove operation panel. They are drop-out
protection types and if they are turned 3 to 4 times,
they will come off. If they are turned excessively,
they may drop out.
②Operation panel is connected to internal main circuit
board with cable. Pull out connector of operation
panel side, then remove operation panel.
Note) Wiring work while operation panel remains
connected, may load to the connector of main circuit
board side and result in loose connection. Be sure to
perform wiring work after cable is removed from
operation panel.
Danger
Do the wiring work after turning off the
main breaker without fail.
