Minuteman Continuous Power Series UPS
FAILED SELF TEST
If the UPS fails its self test, the alarm will sound. Push the reset button for 3
seconds to conduct another self test. If the alarm sounds again (indicating a
second failure), see section 7, Troubleshooting Guide, for instructions.
LINE FAILURE
If AC input fails, the audio alarm sounds and one of the LED above the AC
input icon turns red while the UPS switches to battery power. Press the Test/
Reset button to turn off the audio alarm. The alarm resets when power returns.
See section 7, Troubleshooting Guide, under the AC Input icon for instruc-
tions.
OVERLOAD
When the UPS is overloaded on either line 1 or line 2 the audio alarm sounds and
the top LED on line 1 or line 2 (above the load icon) turns red. The unit will go into
auto bypass. Overloading occurs when loads attached to either line draw more
current than the UPS can provide. See section 7, Troubleshooting Guide, for
instructions about correcting an overload. Press the Test/Reset button to turn off
the alarm. The alarm automatically resets itself once overload problem is cor-
rected.
OVERTEMPERATURE
The audio alarm sounds when the UPS is overheating. Turn off your loads first,
then turn off the UPS. Check to see that the UPS has enough ventilation
space around the unit and that the ventilation grating on the rear panel is clear
of dust and debris. If overheating continues see section 7, Troubleshooting
Guide, for further instructions. Press the Test/Reset button to turn off the
alarm. The alarm automatically resets itself.
SITE WIRING FAULT
The site wiring fault alarm is for single phase models. The alarm sounds and
the middle AC input icon flashes green if the UPS is not grounded properly,
(Hot and Neutral are reversed). See section 7, Troubleshooting Guide, for
further instructions about correcting a site wiring problem. Press the Test/
Reset button to turn off the alarm. The alarm automatically resets itself.
LED I
NDICATORS
The LED indicators, shown in Figure 4-2, are located on the front panel of the
UPS. They tell the user how the UPS is functioning in areas that include AC
input condition, battery level, and percentage of load capacity. There is also an
ON LED, a battery service LED, and a bypass LED. Figure 4-2 shows the
information each LED indicates. See section 7, Troubleshooting Guide for
explanations and solutions for LEDs that indicate a problem.
