Troubleshooting
This section is intended to provide you with some basic troubleshooting assistance
with your readout system. If you cannot correct the problem after following these
instructions, contact your authorized ACU-RITE distributor or OEM/OEI for
repair or replacement procedures.
No Operation
If the readout display will not operate, check the following conditions:
•
Check AC power source.
If the readout cannot be powered up, confirm that
line voltage is present at the source and that the line voltage meets the
required specifications
.
• Check power cord.
Remove the power cord at the electrical input module on
the back of the readout. Determine if line voltage is present at this end of the
cord.
• Check fuse.
With the power cord removed, use a thin straight-blade
screwdriver to remove the cover of the electrical input module. Refer to page
12. Slide out the fuse holder and check the fuse. If necessary, replace it.
Replace the input module cover by snapping it back into place, and reconnect
the power cord.
!
CAUTION
Replace fuses only with the specified type. Using incorrect
fuses can present a safety hazard. The readout may also be
permanently damaged. Refer to the Readout Specification
chart on page 13 for the correct fuse.
NOTICE
If you turn power off, you must wait at least 5 seconds before
turning it back on, or the readout may not power up. This is
because the power supply, in order to withstand brief power
outages and brownouts, requires several seconds to reset
itself.
