Emergency Stop Switches / E-Stop Switches ILLUM ESTOP,TWIST REL, 24-240V RED LED
Research Notes
1. What this is
A6X30120577 is a Siemens command/signalling device identified by an internal material (order) number. These map to real 22mm/30mm SIRIUS pushbuttons, indicators, and mushroom/E-stop operators, but the 8-digit number is a catalog reference and is not structurally decodable from the code alone.
2. Part-number decode
- Type: Siemens material / order number (
A6X30120577) — resolve on the Siemens Industry Mall for the exact device
3. Compatibility & ordering
Look up the material number on the Siemens Industry Mall (mall.industry.siemens.com) or a distributor to get the exact device, then cross-reference by size, function, color, and contact arrangement to an equivalent from another line (Schneider Harmony, Allen-Bradley 800F, IDEC HW, Eaton M22) if needed.
4. Data-quality note
This is a Siemens internal material (order) number. It corresponds to a real Siemens command/signalling device (a 22mm/30mm SIRIUS pushbutton, indicator, selector, or mushroom/E-stop operator), but the number itself does not structurally encode the specs — the exact function, color, contact arrangement, and voltage must be looked up on the Siemens Industry Mall or a distributor datasheet. Kept and documented; flagged needs-verification rather than guessed.

설치 빠른 참조
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.

문제 해결
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.
