4.2 Basic Monitor Panel
Basic Monitoring provides transformer overtemperature alarm, transformer overtemperature
shutdown and Emergency Power Off controls only.
Display Controls and Indicators
• Power Indicator (Green LED) - illuminates when power has been applied to the Liebert Power
product.
• Alarm Status Indicator (Red LED) - illuminates when an alarm is present. The LED will
remain illuminated until the alarm condition is cleared.
• Audible Alarm speaker (represented by the speaker symbol) - a speaker behind the bezel will
sound when there is an alarm condition.
• Silence/Reset Push Button - pressing the Silence/Reset button will silence the audible alarm.
Press the button a second time to clear the alarm and turn off the red alarm indicator LED.
• LCD - Not used
• Emergency Power Off (EPO) Push Button - pressing the EPO button shunt trips the input
circuit breaker to turn the unit off.
• Navigation keys (soft function keys F1 through F4 and Help) - Not used.
If an overtemperature condition occurs—when the transformer temperature exceeds 356°F (180°C)—
it should be investigated and corrected. Possible causes include transformer overload, excessive non-
linear loading, inadequate ventilation, high or low input voltage and monitoring malfunction.
Failure to correct the overtemperature condition may result in an automatic system shutdown due to
the second stage of overtemperature sensing, when the transformer temperature exceeds 392°F
(200°C). After the alarm condition is corrected, the alarm will automatically reset.
See Figure 13 for remote summary alarm and Remote Emergency Power Off switch connections.
