PITgatebox E-Stop with Guard Locking

Pilz PITgatebox Series Introduced circa 2018

Pilz PITgatebox — safety gate box with integrated e-stop and guard locking.

Common Applications

All-in-one safety station for machine guarding. Combines e-stop mushroom button, guard lock monitoring, and reset button in a single IP67 enclosure. Mounts at the machine gate entry point. Wire to Pilz PNOZ safety relay or PNOZmulti controller for SIL 3 / PLe rated safety circuits. Eliminates the need for separate e-stop, guard switch, and reset button.

Installation Quick Reference

Panel cutout: 22mm. Mount with the yellow backing plate visible (required by EN/ISO 13850).

Wiring: Wire NC contacts in series with the safety relay input channels. Use dual-channel wiring for SIL 3 / PLe applications. Never wire directly to a motor contactor.

Testing: Press the e-stop and verify the machine stops within the required time. Test the reset mechanism. Repeat monthly per EN/ISO 13850.

Troubleshooting

E-stop won't reset (twist/pull doesn't release)

Check for debris in the mechanism. For twist-release: turn clockwise 45-90 degrees. For push-pull: pull straight out firmly. If the mechanism is stuck, the internal latch may be damaged — replace the entire head assembly.

Machine doesn't stop when e-stop is pressed

Critical safety issue. Immediately lock out the machine. Check wiring — NC contacts must be in series with the safety relay. Verify the safety relay is functioning. A broken wire in an NC circuit should cause a stop, so check for a wiring bypass.

Safety relay faults after e-stop reset

The safety relay detects a cross-fault between the two monitoring channels. Check that both NC contacts on the e-stop are switching simultaneously. One contact may be welded closed — replace the contact block.
