10.1 Front Panel Indicators
There are four LEDs on the front of the Master Station that provide a visual reference of the overall
health of the Master Station and MOV network. These LEDs are described as follows:
A. Battery - An orange LED indicated that the unit is operating on internal battery power.
B. Network Alarm - A red LED indicates a field network communication fault.
C. MOV Alarm - A red LED indicates an MOV device alarm is present.
D. Power - A green LED indicates that the unit has power.
10.2 Network Status Screen
The Network Status screen provides a visual reference of the overall health of the MOV network.
See Section 5 for instructions on viewing the MOV and communication channel status. MOV faults
can be examined by clicking on the desired unit. Communication channel faults can be examined
and corrected by reviewing log files (see Section 9), verifying correct configuration parameters (see
Section 8), and checking wiring connections and/or network surge protection module on rear of unit.
10.3 Blank Display
A blank display can be the result of the activated screen saver feature. If setting adjustments are
required, please see Section 8. Additionally, the lack of AC/DC power to the Master Station will also
cause a blank screen. After verifying power is available to the unit, disconnect the power and check
the power fuse on the rear of the unit. If it is good, remove the power surge protection module and
check for continuity.
