Table 5-3. SLC Events (Continued)
Probable Cause
A failure of the DC to DC converter in
the device type at address Addr.

Corrective Action
• Check SLC wiring. Refer to
Paragraph 2-8. Ensure that wiring-
resistance and -capacitance
limitations have not been
exceeded.
• Visually inspect the device to
ensure that its red LED is flashing
(if applicable). Use Handheld
Programmer to test the device.
Refer to Appendix D. Replace the
device if it fails the Handheld-
Programmer test.
• List the device's line-voltage level.
Refer to Paragraph 3-2.5.2.3.10.
Line-voltage level must be a
minimum 18 Vdc. Consider using
larger wire gauge if line voltage is
too low.
• Conduct an initiating device test if
the device is an initiating device.
See Paragraph 3-2.5.2.5.1. Be sure
to observe the warnings called out
in this chapter.
• Conduct an output device test if the
device is a control module. See
Paragraph 3-2.5.2.6. Be sure to
observe the warnings called out in
these paragraphs.
• Activate and confirm a proper
operation for the device.
• Replace the device if any of the
above tests are unsuccessful.
• Look for blockages in the HSSD's
piping system
• Use OCS to troubleshoot the HSSD.
The airflow may need to re-
normalized.
• Refer to ORION-XT Installation,
Operation, and Maintenance
Manual, P/N 89.200.
• Register the device if part of
system
configuration. See
Paragraph 3-2.5.2.4.14.
If this procedure is insufficient, try
one of the following procedures:
• Run the AutoLearn Procedure. Refer
to Paragraph 3-2.5.2.4.26.
• Upload a new application program
that includes the previously
unregistered device.
