To resolve an exclamation mark, a red ×, or a down arrow indicator:
1. Make sure your device is enabled:
a. Right-click on the entry that has the indicator.
b. If you see Disable, the device is enabled; if you see Enable, the device is disabled.
•
If the device is enabled, continue with troubleshooting steps.
•
If the device is disabled, click Enable. If this does not remove the indicator, continue to the
next step.
2. Unplug the USB cable either from the Safety Controller or from the computer, wait a few seconds and plug
it back in. If this does not remove the indicator, continue to the next step.
3. Try plugging in the Safety Controller to a different USB port. If this does not remove the indicator,
continue to the next step.
4. Reboot your computer. If this does not remove the indicator, continue to the next step.
5. Uninstall and re-install the software from Add/Remove Programs or Programs and Features located
in the Control Panel. If this does not remove the indicator, continue to the next step.
6. Contact a Banner Applications Engineer.
9.2 Finding and Fixing Faults
Depending on the configuration, the Safety Controller is able to detect a number of input, output, and system faults,
including:
•
A stuck contact
•
An open contact
•
A short between channels
•
A short to ground
•
A short to a voltage source
•
A short to another input
•
A loose or open connection
•
An exceeded operational time limit
•
A power drop
•
An overtemperature condition
When a fault is detected, a message describing the fault displays in the Fault Diagnostics menu (LCD models). For
models not equipped with an LCD, use the Live Mode views in the PC Interface on a PC connected to Controller with the
SC-USB2 cable. Fault diagnostics are also available over the network. An additional message may also be displayed to help
remedy the fault.

Steps to resolve
1.1
Output Fault
Check for shorts
A Safety Output appears On when it should be Off:
•
Check for a short to the external voltage source
•
Check the DC common wire size connected to the Safety Output loads. The wire
must be a heavy-gauge wire or be 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
on page 88)
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 a short between Safety Outputs
•
Check for a short to the external voltage source
•
Check load device compatibility
•
Check the DC common wire size connected to the Safety Output loads. The wire
must be a heavy-gauge wire or be 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
on page 88)
