Mori Seiki Ex Alarm List Free -
This guide is designed to help operators and maintenance technicians understand the alarm structure, common codes, and troubleshooting steps for Mori Seiki EX lathes (typically running on Mori Seiki MS/MSC or Fanuc-based controls).
- EX1040 – PALLET NOT CLAMPED: Pallet clamp sensor is off – machine will not move axes.
- EX1041 – PALLET CHANGE NOT COMPLETE: Cycle start inhibited; check pallet cone seats and hydraulic pressure.
- EX1042 – APC DOOR INTERLOCK: Auto pallet changer door open during pallet swap.
- EX1043 – TOOL MAGAZINE NOT HOME: ATC magazine position sensor failure.
- Cascading alarms: A single root failure—for example, a hydraulic pump breaker tripping—can trigger multiple EX alarms (low pressure, unclamp fault, turret index error). The operator must resist the urge to reset each alarm individually and instead identify the primary fault.
- Sensor dependency: An EX alarm is only as good as its sensor. A faulty level switch can falsely trigger “EX0210 LUBE TANK EMPTY,” leading to unnecessary refills or even an erroneous machine lockout.
- Documentation access: Older machine models may have the EX list only on paper or embedded in the ladder diagram, not easily searchable on the control panel. Newer DMG MORI machines with CELOS (the company’s control and operation software) integrate the EX list digitally, but legacy equipment requires diligent record-keeping.
- Description: Hydraulic pressure below required threshold.
- Typical causes: Low fluid, pump failure, leak.
- First-line actions: Check oil level, inspect for leaks, verify pump operation.
