2.2.5.2 LED indication

The Operation/Display Panel contains the following LED indication:

a. Load on Inverter (Green)

b. Battery operation (Orange)

c. Load on Bypass (Orange)

d. Overload (Orange)

e. LCD Fault (Red)

f. UPS Fault (Red)

2.2.5.3 Emergency Power Off (EPO) button

The UPS shall be provided with a set of terminals which may connect to a remote

EPO contact signal. Remote contact shall be non-powered normally open. UPS shall

also have a unit mounted EPO button.

When the UPS Module EPO button is activated, the EPO function shuts down the

UPS module. The EPO function can be performed both locally and remotely. When

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

dropped.

2.2.6 Micro processor Interface/Diagnostics

2.2.6.1 Microprocessor Controlled Operator Guidance

The UPS microprocessor logic shall, as standard equipment, provide menu-driven

operator instructions detailing the operation of the UPS system. The instruction menu

shall be accessible via a LCD touch screen display located at the control panel. The

micro processor shall monitor each step, thus prompting itself to the next step of the

instructions. The followin g instructions shall be available as a minimum:

a. Inverter stop.

b. Inverter start.

c. Transfer of critical load to static bypass source.

d. Equalize charge to system battery.

2.2.6.2 Microprocessor Controlled Diagnostics

The UPS shall provide microprocessor controlled diagnostics capable of ret aining

fault alarms along with metering parameters in the event of a UPS failure. The

microprocessor memory data shall be viewed via an LCD display or LED located at

the control panel. T he following alarm/status information shall be provided as a

minimum:
