Actuator Function
Momentary = springs back when released. Maintained/latching = stays pressed until pressed again.
|
Push-pull
|
|
Actuator Type
The button head style. Flush sits level with the bezel (prevents accidental presses). Extended protrudes for easy access.
|
Mushroom 38mm
|
|
ATEX Zone
The hazardous area classification. Zone 1 = gas likely present. Zone 2 = gas unlikely. Zone 21/22 = combustible dust.
|
Zone 1, Zone 21
|
|
Certifications
Third-party safety certifications. UL = required for US NEC installations. CE = EU compliance. CSA = Canadian standards.
|
ATEX, IECEx, CE, UL
|
|
Color
Button/actuator color. Green = start/go, Red = stop/emergency, Yellow = caution, Blue = reset (per IEC 60204-1).
|

Hướng Dẫn Cài Đặt Nhanh
Panel cutout: 22.5mm. 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.

Sơ đồ đấu dây
Khắc phục sự cố
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.
