Further Steps and Checks
0.0
Input Fault
Cycle Input
• Check for unstable input signal.
• Turn input OFF to clear the fault indication.
1.1
Output Fault
Check for
Shorts
A Safety Output appears ON when it should be OFF.
• Check for short to external voltage source.
• Check DC common wire size connected to the Safety Output loads. The wire must
be heavy-gauge wire or as short as possible to minimize resistance and voltage
drop. If necessary, use a separate DC common wire for each pair of outputs and/or
avoid sharing this DC common return path with other devices (see section
on page 49).
1.2
Output Fault
Check for
Shorts
A Safety Output is sensing a fault to another voltage source while the output is ON.
• Check for short between Safety Outputs.
• Check for short to external voltage source.
• Check load device compatibility (too much capacitance?).
• Check DC common wire size connected to the Safety Output loads. The wire must
be heavy-gauge wire or as short as possible to minimize resistance and voltage
drop. If necessary, use a separate DC common wire for each pair of outputs and/or
avoid sharing this DC common return path with other devices (see section
on page 49).
1.3 – 1.4
Internal Fault
Internal failure – Contact Banner Factory (see section
9.2 Repairs and Warranty Serv-
on page 82).
1.5
Output Fault
Check Output
Wiring
A Safety Output appears ON prematurely.
• Check DC common wire size connected to the Safety Output loads. The wire must
be heavy-gauge wire or as short as possible to minimize resistance and voltage
drop. If necessary, use a separate DC common wire for each pair of outputs and/or
avoid sharing this DC common return path with other devices (see section
on page 49).
1.6
Internal Fault
Internal failure – Contact Banner Factory (see section
9.2 Repairs and Warranty Serv-
on page 82).
1.7
Output Fault
Check for
Shorts
An overload is detected on the Safety Outputs.
• Check each output terminal for a short to ground or overload condition (a fault on
only one output may cause other outputs to indicate a fault).
• Verify system power supply rating with system load requirements.
1.8
Internal Fault
Internal failure – Contact Banner Factory (see section
9.2 Repairs and Warranty Serv-
on page 82).
1.9
AVM Input Fault
Perform System
Reset
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.
1.10
AVM Input Fault
Perform System
Reset
An AVM input associated with this Safety Output was not closed when the Safety Out-
put was commanded to turn ON.
