RUN EXCITE: Service & Maintenance Manual - rev. 1.5
6.9. “EMERGENCY STOP” MESSAGE ON THE DISPLAY
This error message may appear when:
• the digital plan and 386 boards have detected a dangerous fault;
• the user has pressed the emergency button;
• the emergency button is defective and has transiently opened the contact.
In the above cases the message is justified: simply press the “Clear” key and the machine will
resume operating normally. However, if a problem occurs during the machine’s operation resulting
in:
• loss of communication between the lower and upper assemblies;
• interruption of the power supply to the inverter;
• a non-resettable opening of the emergency button contact.
The display keeps showing the “EMERGENCY STOP” message. If it has been turned on and then
at on again, the “THE EQUIPMENT IS BLOCKED” message will appear in place of the
“EMERGENCY STOP” message, because the machine is unable to actuate any movements with
the inverter turned off. In these cases, follow the troubleshooting procedure described in paragraph
6.10. “THE EQUIPMENT IS BLOCKED” message on the display”.
It might also be helpful to refer to the theoretical explanation of the emergency stop
logic, provided in paragraph 3.4. “Emergency stop management”.
Turn
the machine of f and on again.
