4.3ACCESSING THE LM1/LM2 SET LIMITS FROM OPERATING MODE

The DMVA100 is designed with two manual set limits. The set limits monitor the instantaneous readings, warning the user of abnormal conditions. Each limit can detect readings above or below the set level. SET LIMITS: the point when the relay changes position, if the DMVA100 is equipped with the Relay Option (Suffix -NL).

If a limit is exceeded, the annunciator LM1 and/or LM2 indicator glow and the display flashes, alternating between the instantaneous reading.

4.4VOLTAGE PHASE REVERSAL AND IMBALANCE FROM OPERATING MODE

In a three phase power distribution system, the normal phase shift between each line is 120°. The EPM3000P detects an abnormality and displays a PH message every six seconds.

VOLTAGE PHASE REVERSAL:

If there is an incorrect connection, such as mistaking line A for line B, a PH message appears. The correct sequence is a-b-c.

VOLTAGE PHASE IMBALANCE LIMIT:

Can be detected using the phase imbalance limit in the Programming Mode. The phase imbalance is expressed in a percentage with 0% indicating a 120° phase shift between each line. A PH message appears if the limit is exceeded.
