General Troubleshooting
This section provides a list of general troubleshooting steps to follow
when trying to isolate problems.
•
Check for adequate power . An under-powered unit could
result in unpredictable behavior.
– The 400/600 DC powered terminals require 24V dc at 1.0 A.
– The 400/600 AC powered terminals require 85 to 264V ac.
– The 700-1500 DC powered terminals require 24V dc at 2.9 A.
– The AC Power Supply (2711P-RSACDIN) for 700-1500
terminals meets Class 2/SELV requirements.
•
Check LED indicators on the terminal at startup . Is power
on? Is the unit attempting to start? The red LED should be Off,
except for a few brief flashes, and the green LED should be On.
– If the LEDs remain Off on the 700-1500 terminals, the power
supply or logic module has failed. Check the power cable.
Replace the logic module if the power is within range; if not,
replace the power supply.
– If the LEDs remain off on the 400/600 terminals, check the
power cable.
If the terminal powers up and stops during startup, the state of
the LEDs indicate:
Blinking red LED indicates a recoverable error .
Solid red LED indicates a non-recoverable, fatal error.
