Omron D4BL manual Circuit Connection Example

■Circuit Connection Example

•Terminals 11 and 32 are connected internally and so connect terminals 12 and 31 for safety-circuit input. (GS-ET-19).

•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 status 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.
