Condition

Possible Cause

DNCT does not operate when power is applied, No
text or backlight on display

Check for proper wiring of the 5 pin DeviceNet connector

Check for 24V DC on the DeviceNet Network

Verify that the DNCT cable is plugged in to the unit

DNCT powers up, but never continues past the
"PowerUp" Screen

Verify that there is traffic on the DeviceNet Network.

Press the ESC key. At the Terminal Setup screen, disable "Auto Baud"
and manually adjust the baud rate

Password is set, and then forgot

Using RsNetworks for DeviceNet, find the DNCT on the network, and
set parameter 2 - "Password Override" to override. This will
temporarily override the password in the DNCT. The old password can
then be viewed and changed from the DNCT. The password is only
overridden until the DNCT is powered down
