c. Battery Operation

d. Output Overload

e. Rectifier Operation

f. Inverter Running Synchronously

g. Static Bypass Input Out of Range

h. Minor Fault Data

i. Major Fault Data

B. LED indication

The Operation/Display Panel contains the following LED indication:

a. Load on Inverter (Green)

b. Battery operation (Yellow)

c. Load on Bypass (Green)

d. Overload (Red)

e. LCD Fault (Red)

f. UPS Fault (Red)

C. Emergency Power Off (EPO) button

When the UPS Module Emergency Power Off (EPO) button is activated, the

EPO function shuts down the UPS module. The configuration of the UPS

MMS will depict the subsequent system operation. Refer to previous section

Individual UPS Module EPO. The EPO function can be performed both locally

at the UPS Module and remotely from the CLC System EPO button. When

remote EPO is performed, all system UPS Modules will be shutdown and the

critical load dropped.

2.2.8. UPS status and function interface

In addition to the communication capabilities of the UPS Module LCD, the

following communication methods are available: RS-232C/RS-422

Communication Port: The UPS Module will have as standard a RS-232C/RS-422

port allowing the user to interface to the UPS module offering the following

functions:

2.2.9. Additional UPS Module Monitoring functions

1. Via Personal Computer (PC) - Mitsubishi Electric Diamond Link Software

2. Via Netcom (SNMP/Web Card)

2.2.10. Service functions via PC

Waveform capture trace information: Upon UPS failure, a trigger will initiate

capture of UPS Module Waveform, logic and control signals. The capture duration

will be for 10 cycles, 5 cycles pre trigger and 5 cycles post trigger. The sampling

frequency shall be 7.2kHz, therefore a total of 120 samples per cycle will be taken.

The captured data can be downloaded to a PC and displayed on Mitsubishi

Electric Software. The Software allows selection of UPS Module Waveform, logic

and control signals for display and zoom functions. Waveform capture information

assists service personnel for troubleshooting and undertaking UPS Module failure

root cause analysis.
