2.3 or 2.5 Concurrency Fault Cycle Input
On a dual-complementary input, with both inputs of one complementary pair in
the Run state, one input of this complementary pair changed to Stop then back
to Run:
•
Check the wiring
• Check the input signals
• Check the power supply providing input signals
• Consider adjusting the debounce times
2.4 or 2.6 Simultaneity Fault Cycle Input
On a dual-complementary input, one input of a complementary pair went into
the Run state, but the other input of the same complementary pair did not follow
the change within the time limit:
•
Check the wiring
• Check the input signal timing
2.7 Internal Fault

2.8 – 2.9 Input Fault Check Terminal xx
Input stuck high:
• Check for shorts to other inputs or other voltage sources
• Check the input device compatibility
2.10 Input Fault Check Terminal xx • Check for a short between inputs
2.11 – 2.12 Input Fault Check Terminal xx • Check for a short to ground
2.13 Input Fault Check Terminal xx
Input stuck low
•
Check for a short to ground
2.14 Input Fault Check Terminal xx
Missing test pulses:
•
Check for a short to other inputs or other voltage sources
2.15 Open Lead Check Terminal xx • Check for an open lead
2.16 – 2.18 Input Fault Check Terminal xx

2.19 Open Lead Check Terminal xx • Check for an open lead
2.20 Input Fault Check Terminal xx
Missing test pulses:
• Check for a short to ground
2.21 Open Lead Check Terminal xx • Check for an open lead
2.22 – 2.23 Input Fault Check Terminal xx • Check for an unstable signal on the input
2.24
Input Activated While
Bypassed
Perform System Reset A Two-Hand Control input was activated (turned On) while it was bypassed.
2.25 Input Fault
Monitoring Timer
Expired Before AVM
Closed
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
• Contact Banner Engineering
2.26 Input Fault
AVM Not Closed When
Output Turned On
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 Check Terminal xx
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 Check Terminal xx
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 Check Terminal xx
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 Check Terminal xx
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 Terminal xx • Check for an unstable signal on the input
