Events (alarms and messages)

TLE Scalable Series 40 to 150 UL S1 UPS User Manual / REV-B

Each of the following listed events, alarm or message, can be displayed on the LCD screen, on a PC with the software “Data Protection” installed or with the monitoring system “iUPSGuard”.

Alarms and Messages are differently specified because the alarms are indicating an abnormal functioning of the

UPS (which are additionally signaled with the LED ALARM and acoustically with the buzzer ), while the messages indicate the various states of operation of the UPS (stored in the events list, but not activating the LED ALARM and the acoustical alarm).

Description

The alarm signals an Inverter outlet fuses fault, causing it to switch off immediately.

It may only be manually switched on after the alarm has ceased.

K7 not closed despite a closing command.


Load will be supplied by Utility.

K7 not open despite an opening command.


Load will be supplied by Utility.

The temperature sensor of the Inverter Transformer indicates overtemperature.

Elapsed “stop operation” time, Inverter shut-down.

With Utility OK, Load is transferred on Utility.

Blown input DC fuse(s) F1 of the Inverter.

Inverter cannot be started as long as present.

An abnormal condition has been detected on one or more power modules of the Inverter (temperature or overcurrent).

Inverter shut-down and cannot be started as long as the alarm is present.

Indicates a failure on the driver board or the Rectifier IGBT bridge. The Rectifier is shut-down.

Driver Booster error signal.

Inverter Output Voltage is out of the tolerances ( ± 10%).

Inverter is switched OFF.

Detection of Inverter Bridge (Is) current limit causing the

Inverter OFF and automatic re-start.

After 3 times the Inverter switches-Off and it can be restarted manually.

A high exchange current value is detected between the UPS of the RPA Parallel System.

The “Slave” oscillator is not in synchronized with the

Master; thus causing the shut-down of its Inverter.

If after a restart the condition remains, the LED inside the

Inverter symbol on the panel will not light up, indicating that this Inverter cannot supply the Load anymore.

Auxiliary contact signal (normally closed) indicates that one fuse of the Bypass Utility (F16/17/18) is open.

K6 open despite a closing command being issued.


The Load cannot be supplied by Automatic Bypass.

K6 closed despite an opening command being issued.


A faulty current has been detected in the static-switch causing the opening of the contactor K6 for 10 seconds.

After 3 times K6 remains definitively open.

Only an ABB Service Technician can reset the alarm.

The Utility Bypass Voltage is out of the tolerances ( ± 10%).

K6 opens, synchronization with Utility is inhibited and transfer to Utility is blocked.

K3 open despite a closing command.

Inverter is switched OFF.

It can be restarted manually after recovery of the alarm condition.

Alarm Description

K3 OPENING FAILURE

NO INVERTER POWER

FAN FAILURE

LOAD LOCKED ON UTILITY

LOAD ON UTILITY BY ERROR

DETECTOR

K3 not open despite an opening command.

Be aware the DC Capacitors could remain charged.

The Load supplied by Utility exceeds the Inverter power.

The Load remains supplied by Utility until the alarm stays ON.

The Fan Control Board indicates a malfunction of one or more ventilators.

Load is locked on Utility because 3 transfers on Utility have been detected in a short time (default 30 sec.).

The transfer will be free after a time defined in parameter

(default 30 sec.).

Load is transferred to Utility because the error detector detected a disturbance on the output voltage.

EMERGENCY OFF ACTIVATED

OVERLOAD

OVERLOAD: LOAD ON UTILITY

INVERTER AND UTILITY

NOT SYNCHRONIZED

ECO CONFIG FAILURE

Alarm after detection of an EPO (Emergency Power Off) from an external safety device connected on Customer Interface

Board. Consequently K4, K6, K7 open, Rectifier, Inverter and

SSM are switched Off.

The UPS system is in an overload condition > 105% on

Inverter, or > 150% on Utility.

With Utility unavailable, a sequence of “stop operation” starts. Time out depends on degree of overload.

With Utility Bypass supply available and Load > 115%, the

Load is transferred on Utility. Load will be transferred again automatically on Inverter when Load < 100%.

The voltages of Utility and Inverter are not synchronized, which causes the opening of K6.

The propagation of the eBoost / IEMi configuration to other

Units in an RPA Parallel System failed.

Detection of a failure on the Power Supply Board, in particular from the DC supply.

Can be enabled or disabled with respective parameter.

A time of lost redundancy superior than specified in respective parameter was detected.

The Load is locked on Inverter after 3 Load transfers within

30 seconds.

After time out (default 30 sec.) Bypass will be free.

An overtemperature condition has been detected on Inverter.

Elapsed “stop operation” time, Inverter shut-down.

With Utility OK, Load is transferred on Utility.

Load Off after time-out of “stop operation” for overload on

Inverter (time depending on the % of overload).
