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.
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.
