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.
Red LED Green LED Indication

Red LED Green LED Indication
On Off Fatal hardware error occurred. Replace
logic module (700-1500) or the terminal
(400 and 600).
On Blinking Fatal hardware error occurred in Display.
Replace the display module (700-1500) or
the terminal (400 and 600).
After a successful startup, both LEDs are
off and controlled by the application
running on the terminal.
