Fault Code
Fault Code Description
Steps to resolve
2.8 – 2.9
Input Fault
Input stuck high:
•
Check for shorts to other inputs or other voltage sources
•
Check the input device compatibility
2.10
Input Fault
•
Check for a short between inputs
2.11 – 2.12
Input Fault
•
Check for a short to ground
2.13
Input Fault
Input stuck low
•
Check for a short to ground
2.14
Input Fault
Missing test pulses:
•
Check for a short to other inputs or other voltage sources
2.15
Open Lead
•
Check for an open lead
2.16 – 2.18
Input Fault
Missing test pulses:
•
Check for a short to other inputs or other voltage sources
2.19
Open Lead
•
Check for an open lead
2.20
Input Fault
Missing test pulses:
•
Check for a short to ground
2.21
Open Lead
•
Check for an open lead
2.22 – 2.23
Input Fault
•
Check for an unstable signal on the input
2.24
Input Activated While
Bypassed
A Two-Hand Control input was activated (turned On) while it was bypassed.
2.25
Input Fault
After the associated Safety Output turned Off, the AVM input did not close before its AVM
monitoring time expired:
•
The AVM may be disconnected. Check the wiring to the AVM
•
Either the AVM is disconnected, or its response to the Safety Output turning Off is too
slow
•
Check the wiring to the AVM
•
Check the timing setting; increase the setting if necessary

2.26
Input Fault
The AVM input was open, but should have been closed, when the associated Safety Output was
commanded On:
•
The AVM may be disconnected. Check the wiring to the AVM
3.1
EDMxx Fault
EDM contact opened prior to turning On the Safety Outputs:
•
Check for a stuck On contactor or relay
•
Check for an open wire
3.2
EDMxx Fault
EDM contact(s) failed to close within 250 ms after the Safety Outputs turned Off:
•
Check for a slow or stuck On contactor or relay
•
Check for an open wire
3.3
EDMxx Fault
EDM contact(s) opened prior to turning On the Safety Outputs:
•
Check for a stuck On contactor or relay
•
Check for an open wire
3.4
EDMxx Fault
EDM contact pair mismatched for longer than 250 ms:
•
Check for a slow or stuck On contactor or relay
•
Check for an open wire
3.5
EDMxx Fault
•
Check for an unstable signal on the input
3.6
EDMxx Fault
•
Check for a short to ground
3.7
EDMxx Fault
•
Check for a short between inputs
3.8
AVMxx Fault
After this Safety Output turned Off, an AVM input associated with this output did not close before
its AVM monitoring time expired:
•
The AVM may be disconnected or its response to the Safety Output turning Off may be
too slow
•
Check the AVM input and then perform a System Reset to clear the fault
