Alarm message

 

Description

 

 

 

The temperature of the inverter heat sink is too high to keep inverter running. This alarm is triggered

 

 

 

by the signal from a temperature monitoring thermostat on the inverter bridge heat sink. The UPS will

 

Inverter overtemp.

 

recover automatically after a 5 minute delay from the disappearance of the overtemperature signal. If

 

 

 

the overtemperature condition is true, then check for and verify: 1. high ambient air temperature. 2.

 

 

 

blocked cooling airway. 3. any fan failure. 4. prolonged inverter overload

 

 

 

 

 

Fan fault

 

At least one of the cooling fans has failed

 

Inverter STS fail

 

At least one of the static switches of inverter side is open or short circuit. This fault is locked until

 

 

power off

 

 

 

 

 

 

 

 

Bypass STS fail

 

At least one of the static switches of bypass side is open or short circuit. This fault is locked until

 

 

power off

 

 

 

 

 

 

 

 

Operation invalid

 

This record is registered following an incorrect operation

 

 

 

The UPS is confirmed to be overload when the load arises above 105% nominal rating. The alarm

 

 

 

automatically resets once the overload condition is removed. 1. Confirm that the alarm is true by

 

Unit over load

 

checking the load percent indicated on the LCD to determine which phase is being overloaded. 2. If

 

 

the alarm is true, measure the actual output current to verify that the indications are valid.

 

 

 

 

 

 

Disconnect unnecessary load and ensure the safety. In a parallel system, a severe load sharing error

 

 

 

can also leads to the alarm

 

 

 

 

 

 

 

The UPS parallel system is confirmed to overload when the total load arises above 105% nominal

 

 

 

rating for the set basic number of UPSs. The alarm automatically resets once the overload condition

 

 

 

is removed.

 

System over load

 

1. Confirm that the alarm is true by checking the system load percent indicated on the LCD to

 

 

determine which phase is being overloaded. 2. If the alarm is true, measure the actual output current

 

 

 

 

 

 

to verify that the indications are valid.

 

 

 

Disconnect unnecessary load and ensure the safety. In a parallel system, a severe load sharing error

 

 

 

can also leads to the alarm

 

 

 

 

 

 

 

The UPS is confirmed to overload and the overload times out.

 

 

 

Note 1: the highest loaded phase will indicate overload timing-out first. Note 2: When the timer is

 

 

 

active then alarm “unit overload” should also be active as the load is above nominal.

 

 

 

Note 3: When the timer has expired, the inverter Static Switch is opened and the load transferred to

 

Unit over load timeout

 

bypass. The inverter shutdown and will restart after 10 seconds. Note 4: If the load decreases lower

 

 

 

than 95% after 5 minutes, the system will transfer back to inverter mode.

 

 

 

Confirm that the alarm is genuine by checking the load percent indicated on the LCD. If an overload

 

 

 

is indicated then check the load, and investigate any additional load connected prior to the alarm (if

 

 

 

applicable)

 

 

 

 

Byp. abnormal shutdown

Both bypass and inverter voltages unavailable. Load interruption

 

Inverter over current

Inverter pulse width modulation module overloaded

 

 

 

The phase sequence direction of bypass voltage is reversed. Normally, the phase of phase B lags

 

Bypass phase reverse

 

120 degrees behind phase A, and the phase of phase C lags 120 degrees behind phase B.

 

 

Verify that the phase rotation of the bypass supply presented to the UPS is correct, and rectify it if it

 

 

 

 

 

 

is found to be in error

 

 

 

 

 

Load impact transfer

 

A transfer to bypass occurred due to a large step load. The UPS should recover automatically. Turn

 

 

on connected equipment in sequential order to reduce the step loading of the inverter

 

 

 

 

 

 

 

 

Transfer time-out

 

The load is on bypass power due to excessive number of transfers that occurred within the last hour.

 

 

The UPS will recover automatically and will transfer the load back to inverter power within an hour

 

 

 

 

 

 

 

 

Load sharing fault

 

UPS modules within a parallel system are not sharing the load current equally

 

DC bus abnormal

DC input voltage to inverter beyond limits. Inverter shuts down. Load transfers to bypass

 

System transfer

 

The whole paralleled UPS system transferred to bypass at the same time. This message will appear

 

 

on the UPS which passive transfer to bypass

 

 

 

 

 

 

 

 

Parallel board fault

 

Malfunction of the paralleling control circuits of this UPS module. Can cause system transfer to

 

 

bypass

 

 

 

 

 

 

 

 

 

 

The parallel cables are not connected correctly in a parallel system.

 

Parallel connect fault

 

Reset the fault by pressing the FAULT CLEAR button, then restart the inverter by pressing the

 

 

 

INVERTER ON button

 

 

 

 

Bypass over current

Bypass current is over limit above 135% rating. The UPS just alarms and does nothing

 

LBS Active

 

Load Bus Synchronization is active. The UPS is acting as an LBS master or slave in a dual bus

 

 

configuration

 

 

 

 

 

 

 

 

LBS abnormal

 

UPS set to LBS mode (master or slave), but no LBS signal on LBS bus. Check the LBS bus

 

 

connection

 

 

 

 

 

 

 

Byp. induct overtemp.

Bypass load sharing inductor overtemperature. Check the environment and ventilation

 

Static Sw. overtemp.

Overtemperature of static switch on bypass or inverter side. Check the environment and ventilation
