37246, Emergency Stop relay conflict
Description
Only one of the two emergency stop chains was opened internal
on safety interface board (SIB).
Consequences
The system remains in the Emergency Stop status.
Recommended actions
Press emergency stop and reset emergency stop once again.
Replace SIB if faulty.
37247, Circulation Fan arg malfunction
Description
Circulation fan for the drive systems at the cabinet rear side
has stopped or is rotating very slowly.
Consequences
The drive systems temperature will rise.
Probable causes
Faulty fan, cabling or power supply. See the circuit diagram!
Recommended actions
Check the fan cables. Check the power supply. Check the fan.
37248, Circulation Fan arg malfunction
Description
Circulation fan in the cabinet front door has stopped or is
rotating very slowly.
Consequences
The temperature in the cabinet will rise.
Probable causes
Faulty fan, cabling or power supply. See the circuit diagram!
Recommended actions
Check the fan cables. Check the power supply. Check the fan.
37249, Glitch in Emergency Stop circuits
Description
Two or several status changes detected on signal within few
milliseconds. This message is most likely caused by bad
connections in ES_INPUT circuits.
Consequences
Motors and paint equipments are maybe switched off.
Recommended actions
Check cables and connections on the safety system for
ES_INPUT.

37250, Glitch in Auto Mode Stop circuit
Description
Two or several status changes detected on signal within few
milliseconds. This message is most likely caused by bad
connections in MODE_STOP circuits.
Consequences
Motors are maybe switched off.
Recommended actions
Check cables and connections on the safety system for
Auto_Mode_Stop (or Test_Mode_Stop / Enabling Device).
37251, Glitch in Delayed Stop circuit
Description
Two or several status changes detected on signal within few
milliseconds. This message is most likely caused by bad
connections in DLY_STOP circuits.
Consequences
Motors are maybe switched off.
Recommended actions
Check cables and connections on the safety system for
DLY_STOP.
37252, Glitch in General Mode Stop circuit
Description
Two or several status changes detected on signal within few
milliseconds. This message is most likely caused by bad
connections in GM_STOP circuits.
Consequences
Motors are maybe switched off.
Recommended actions
Check cables and connections on the safety system for
GM_STOP.
37253, Glitch in Run Chain on SIB
Description
Two or several status changes detected on signal within few
milliseconds. This message is most likely caused by bad
connections in safety interface board (SIB) Run_Chain circuits.
Consequences
Motors are maybe switched off.
Recommended actions
Check cables and connections on the safety system. Check for
other error messages for external connections (interlocks).
