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 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 open the cover of the electrical input module. Refer to page 25. Slide out the
fuse holder and check the fuse. If necessary, replace it. Close the input module
cover by snapping it back into place, and reconnect the power cord.
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.
CAUTION
Only replace fuses 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 30 for
the correct fuse.
