Problem Solution
You applied power to the
unit, but the display does
not come on.
1. Check fuse F1. If blown, replace.
2. If the fuse is okay, check to see if the green power LED (in the middle of the
motherboard inside the enclosure) is illuminated. If it is not illuminated:
a. Check if the power switch (inside the enclosure in the upper right corner
next to the AC connection) is on. Turn on if necessary.
b. Check if there is voltage coming to the unit. Fix power supply or wiring to
the unit if necessary.
3. Check the contrast setting for the display. It could be set too light for you
to view the display. Follow this exact sequence to check and increase the contrast.
a. Press the Scan/Hold key to put the controller in Manual Mode.
b. Press the Menu key to access the Main/Display Menu.
c. Press 17
d. Press Enter
e. Press the Up/Down Arrow keys repeatedly to darken the contrast. You may
need to press them 20 to 40 times to see any effect on the display.
4. Turn off the unit, then while holding the period key, turn unit back on.
5. If the display still does not illuminate, contact the Bindicator Service
Department.
You applied power to the
unit and want to perform
