Circuit Connection Example
• Do not connect the indicators to the safety contact terminals (11-
12-31-32) or the safety circuit side.
• When using indicators, connect them to the auxiliary circuit side
(monitor circuit) or the solenoid input terminals as shown below.
• The indicators can be used to confirm the open/closed status of the
door, the ON/OFF status of the power supply, and the ON/OFF sta-
tus of the solenoid.

• Do not connect the indicators in parallel with the direct opening
contact. If the indicators are broken, a short-circuit current may
flow, causing equipment to malfunction.
• The 24-VDC solenoid terminals have polarity. Confirm the polarity
before wiring.
• Be sure to use a special pushbutton switch to stop and start
machinery and release locks.
