7.1. SAMPLE PROBLEMS AND THEIR SOLUTIONS
There is no power to the unit
Check the power cabling and the integral fuse in the IEC mains socket at the rear of the
frame.
Check that the power switch at the rear is in the on position.
The bargraph display does not have the desired ballistics or color transition points
Check that the appropriate scale and color transition points have been selected with the
internal DIL switches.
Check that the chosen ballistics setting and bargraph scale graticules match.
An alarm continues to sound even though normal signals have been restored
Mute the alarm with the ALARM MUTE switch or reset all alarms with the ALARM RESET
switch by holding it upwards for more than 3 seconds.
An input signal has failed but no alarm was asserted
