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 local and remote. When

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

load dropped.

2.2.6 Microprocessor 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 microprocessor shall monitor each step, thus prompting itself to the next step of

the instructions. The following instructions shall be available as a minimum:

a. Inverter stop.

b. Inverter start.

c. UPS shutdown.

d. UPS startup

e. Transfer of critical load to static bypass source.

f. Equalize charge to system battery.

2.2.6.2 Microprocessor Controlled Diagnostics

The UPS shall provide microprocessor controlled diagnostics capable of retaining

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

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

control panel. The following alarm/status information shall be provided as a

minimum:

a. Load on Inverter

b. Inverter Operation

c. Battery Operation

d. Battery Low Voltage

e. Output Overload

f. Remote Operation

g. Battery Depleted

h. Battery Temperature Abnormal

i. Rectifier Operation

j. DC Breaker Open

k. Rectifier Input Out of Range

l. Equalize Charge Activated

m. Inverter Running Synchronously

n. Load on Bypass

o. Static Bypass Input out of Range
