What the 15000 alarm means

The safety controller reports the E-stop or safeguard chain open; all servo power is cut. Codes around 15000 are safety-level events from the xCore safety unit. This fault ranks high in our ROKAE xCore (XB / CR / NB series) service records, and the first site inspection usually finds the source.

Most common causes

  • E-stop pressed on pendant, cabinet, or cell
  • Safety gate open
  • External scanner/mat triggered
  • Dual-channel safety wiring mismatch
Field note: The first cause shows up most on real machines, so verify it before you go further.

Step-by-step field fix

  1. Release every E-stop and close all gates
  2. Clear triggered scanners or mats
  3. Press safety reset on the pendant
  4. If the chain stays open, meter both channels for a mismatch
  5. Re-enable servos and test manual motion
Safety first: For ROKAE 15000, this alarm is the safety circuit itself: jumpering a door switch or forcing a contactor removes the protection entirely - no protective action when something happens, and no defensible account of responsibility. What you can check yourself first is Release every E-stop and close all gates; the e-stop chain and safety circuit handling is not a DIY job.

How we diagnose safety-chain faults on site

ROKAE 15000 belongs to the safety chain & e-stop family. On ROKAE 15000 the failing stage is safety circuit plus collaborative safety functions on the ROKAE xCore controller - continuity of one series loop: e-stop buttons, door switches, light curtains, safety relays and the enabling device. We start reading ROKAE 15000 at the pendant alarm list; codes segment as 1xxxx / 5xxxx / 6xxxx.

The chain involved in ROKAE 15000 runs: e-stop / door / curtain -> safety relay (dual channel) -> controller safety input -> motor-off and brake apply.

On ROKAE 15000 the field usually reports E-stop pressed on pendant, cabinet, or cell, but the check that matters is not continuity: The point of a safety loop is not whether it conducts but whether both channels conduct together. The relay compares channels; if one opens tens of milliseconds early it latches as a channel fault. The commonest causes are plain: oxidised door-switch contacts raising contact resistance, or one loose terminal. We measure segment by segment - pendant e-stop, panel e-stop, external e-stop, safety door - and lock onto whichever segment reads differently on the two channels.

Frequently asked questions

QWhat does the ROKAE 15000 alarm mean?

The safety controller reports the E-stop or safeguard chain open; all servo power is cut. Codes around 15000 are safety-level events from the xCore safety unit. This fault ranks high in our ROKAE xCore (XB / CR / NB series) service records, and the first site inspection usually finds the source. ROKAE 15000 sits in the safety chain & e-stop family; on our work orders the highest-frequency trigger for this code is "E-stop pressed on pendant, cabinet, or cell".

QCan I clear a ROKAE 15000 alarm myself?

Whether ROKAE 15000 clears on its own depends on the outcome of "Release every E-stop and close all gates". Finish the flow with "Re-enable servos and test manual motion" to confirm ROKAE 15000 - do not skip it. If that step is clean, the second most frequent cause on ROKAE 15000 is "Safety gate open". Do not chase takt through a repeating ROKAE 15000. Left alone, safety chain & e-stop faults tend to graduate from repairable to must-replace.

QA safety-chain fault like ROKAE 15000 stops the line - how fast can you be here?

The commonest causes we see on ROKAE 15000 are "E-stop pressed on pendant, cabinet, or cell, Safety gate open, External scanner/mat triggered", so we stock the van against those. For ROKAE 15000 specifically, we stock along the loop: safety relays, common door switches, e-stop buttons, light-curtain pairs and terminal blocks. For ROKAE 15000, a safety-chain fault stops the whole line, so we rank it top priority and pre-triage by phone: door switch, e-stop or relay. Before we roll, tell us what ROKAE 15000 shows on the pendant alarm list; codes segment as 1xxxx / 5xxxx / 6xxxx and what the machine was doing - phone or video triage is free.
