Overview
PS-3 series safety edge controller.
The PS-3 series of single-channel/dual-channel controllers can be used with all GREIN safety contacts and strip switches to increase the safety level of safety contacts and control system compatibility.
Electrical wiring diagram for safety contact edge controller
Depending on the internal wiring of the safety contact edge, the wiring of the safety contact edge controller can be divided into 2-wire and 4-wire types.
2-wire type (for manual reset: connect the 1NO self-reset button between terminals 4-6; for automatic reset: directly short-circuit terminals 4-5).
4-wire type (for manual reset: connect the 1NO self-reset button between terminals 4-6; for automatic reset: short-circuit terminals 4-5 directly).
Note: Multiple 4-wire safety contacts can be connected in series and controlled by a single controller.
4-wire series wiring method (for manual reset: connect the 1NO self-reset button between terminals 4-6; for automatic reset: directly short-circuit terminals 4-5).
Note: The maximum length of the safety contact edge that can be connected in series is 60m. The maximum length of the connecting wire is 250m, with a cross-sectional area of 0.35mm.
Controller function status indication
Note: The safety edge has no safety function when used alone. The 2-wire edge has 1 NO contact, and the 4-wire edge has 2 NO contacts (the red wire and the black wire each form a pair of NO contacts).
