Alarms 

In the case one or more of the Alarm setting parameters is exceeded, the alarm event is stored in the nonvolatile memory of the device and indicated on the display as explained below:

ALARM RECORDS

RESPONSE

DEFINITION

CURRENT LIMIT

·        Alarm Led is lit

·        The alarm duration and starting time are recorded

·        The name of the alarm and the current limit value is displayed consecutively.

·        The output voltage is decreased to hold the current at the specified current limit

This alarm informs the user of overload case

OVERVOLTAGE

·        Alarm Led is lit

·        The alarm duration and starting time are recorded

·        The name of the alarm and the output voltage are displayed consecutively.

·        In case this alarm occurs 6 times a day, the module stops its operation and “DISABLED (OVL)” is displayed. The module should be reset to be put into operation.

This alarm informs the user that the output voltage is higher than the pre-specified  voltage level. This level can be adjusted between 54V – 59V in normal mode, and between 63V – 68V in equalizing mode

LOW VOLTAGE

·        Alarm Led is lit

·        The duration and starting time are recorded

·        The name of the alarm and the output voltage are displayed consecutively.

This alarm informs the user that the output voltage is lower than the pre-specified voltage level. The level can be adjusted between 45V – 48V. This alarm is disabled in AUTO mode.

EXTREME LOW VOLTAGE

·        Alarm Led is lit

·        The duration and starting time  are recorded

·        The name of the alarm and the output voltage is displayed consecutively.

This alarm informs the user that the output voltage is lower than the pre-specified voltage level. The level can be adjusted between 42V – 45V. This alarm is disabled in AUTO mode.

AC OUT OF LIMITS

·        Alarm Led is lit

·        The alarm duration and starting time are recorded

·        The name of the alarm and the input voltage are displayed consecutively.

·        No output will be generated

This alarm informs the user that the input voltage is not between 60V and 275V. Once this alarm occurs, the module start to operate when the input voltage falls below 260V, or rises above 76V.

OVERTEMPERATURE

·        Alarm Led is lit

·        The alarm duration and starting time are recorded

·        The name of the alarm is displayed.

·        No output will be generated

·        In  the case this alarm occurs 6 times a day, the module stops its operation and “DISABLED (TEMP)” is displayed. The module should be reset for putting into operation.

This alarm informs the user that the temperature of the heat sink  is higher than 80°C.
