Q: Whe n will happe n “Batte ry c irc le c irc uit bro ke n alarm”?

A: 1/ Powe r s witc h of the batte ry

on EPS 90 rack is off

2/ Powe r s witc h o f the batte ry

in battery c abine t is off

3/ Co ntac to r o f BLVD ins ide the EPS 90 rac k is open

The “battery circle circuit broken alarm” will happen, if one of the up

presupposition exist.

3/ Che c k the batte ry bank voltage

 If all the Power switch of battery is on, and AC(EVN) shut down, and battery bank voltage lower than 43V, the APM30 is working normal The generator should be start to supply power (read next page)

A: When AC(EVN) shut down, the battery discharge to supply the load.

 When battery voltage lower than 44V, APM30 will open LLVD contactor, disconnect the load of LOAD1.

 When battery voltage lower then 43V, APM30 will open BLVD contactor, disconnect the load of LOAD2

Note: LLVD: Load Low Voltage Disconnect

Step1: Install PMU and PSU, Connect AC input, disconnect battery, Disconnect

Load1 and Load2, Put off Power switch of the battery;

Measure the Voltage between BAT.(+) and BAT.(-), voltage between RTN(+) and Load1(-), Voltage between RTN(+) and Load2(-) All of the voltage should

be about 53.5V.

Step2: Uninstall (take off, hot plug ) PMU;

Measure the Voltage between BAT.(+) and BAT.(-), it should be 0V;

Step3: Install PMU, Put on Power switch of the battery;

Use one cable to short circuit BAT.(-) and LOAD2(-), the voice of contactor be put on should be heard.

Step4: Remove the short circuit cable;

Measure the Voltage between BAT.(+) and BAT.(-), it should be 53.5V.

Step5: Uninstall (take off, hot plug ) PMU;

Measure the Voltage between BAT.(+) and BAT.(-), it should be 53.5V.

If all results as same as the up-step, the EPS90 sub-rack is working normally.

 The pro ble m de s c riptio n:

1/ There is no output in Load1;

2/ If the AC shut down the battery can’t supply the load, both load1 and load2

The problem happen on 144077/144076 sites.

The function of the temp sensor:

1/ Use for temperature compensation The float charge voltage is 53.5V at 25 , ℃

if temperature over 25 , APM30 will reduce float charge voltage, ℃ 80mV/bank/ The function will protect battery against expand ℃ 2/ For high temperature alarm If the temperature of battery cabinet over

50 , PMU will send high temperature alarm and then cut off the battery ℃

Wrong Ins tallatio n:

The battery temp sensor extend by ground cable

The battery temp sensor cable bend too much
