Troubleshooting

Due to the many features and functions of the scanner, it’s possible that the setup of the scanner does not agree with

what an operator expects to see. If the scanner is not working as expected, refer to the

Diagnostics

menu and consult

the recommendations described below.

Troubleshooting Tips

Symptom

Check/Action

No display or faint display Check power connection.

Press and hold

Menu

key for 5 seconds to check for Standby mode. If “

WAKEUP?

” is

displayed, press the

Enter

key to awaken the scanner from Standby mode.

SafeTouch Buttons do not

respond

If

is displayed, hold

Menu

SafeTouch button to leave power save mode.

If is flashing, wait 60 seconds to leave mechanical pushbutton lockout mode.
If the cover was recently tightly secured, you may need to wait up to 2 minutes for

buttons to self-calibrate to the new cover position due to glass reflection.
Verify THRU-GLASS BUTTONS switch on display module is in ON position.
Sunlight can interfere with the sensors. It is recommended to shield the window while

operating the buttons by standing so as to block direct sunlight.

Scanner channel display

NONE

Verify that the polling parameters (slave address, register, etc) are correct. If the

channel is a math channel CV, verify the chosen math function does not include any

NONE selections or un-programmed Modbus PVs.

Long time between

channel value updates

Verify all channels are communicating. Errors, combined with long timeouts and high

allowable number of failures when polling Modbus devices, will combine to

significantly delay the polling speed. Reduce the number of allowable timeout errors

to check that communications are successful, and if there are errors, reduce the

timeout if possible.

Rate display unsteady

Increase low gate setting in Ad

vanced

menu.

Scanner displays span

error message during

scaling

Verify minimum input span requirements

Scanner flashes maximum

display

Check slave device registers are valid. Check math channels are not exceeding

maximum possible display. Check input signal is within scaled range of 99999.

Rate display response is

too slow

Check if gate settings can be lowered

.

If the display locks up or

the scanner does not

respond

Perform hard reset by removing the display module or by removing DC power.

Backlight does not

appear.

Backlight is intended for viewing assistance in dim lighting. It may not be noticeable

under good lighting conditions.

Other symptoms

Call Technical Support for assistance.

Note: Certain sequences of events can cause unexpected results. To solve these issues, it is best to start fresh from

factory defaults and map changes ahead of time, rather than at random.
