Emergency Stop Switches / E-Stop Switches PB LGMSHD BKBZ R
Research Notes
1. What this is
E22JLB2N8 is an Eaton E22 economy 22mm command switch / contact element (compact 22mm control device).
2. Part-number decode
- Series: E22
- Panel cutout: 22mm
3. Compatibility & ordering
Eaton's M22 (RMQ-Titan, 22mm) and E30 / 10250T (30.5mm heavy-duty) are its principal command-switch ranges. This is a complete/integrated device. Match by size (22 / 30.5mm), function (pushbutton/selector/indicator/E-stop), color, illumination, and contact arrangement; cross-reference to Schneider Harmony, Allen-Bradley 800F/800T, Siemens 3SU, or IDEC HW by the same attributes if needed.
4. Data-quality note
The Eaton series/family is identified; the exact configuration (color, contact, function) is left to the Eaton datasheet rather than guessed. Flagged decoded-partial.

Référence rapide d'installation
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.

Dépannage
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.
