Ratio
- 5/5 25000/1 600/1
Enter the primary and secondary values
for the current transformer.
Voltage Transformer
Ratio
- 0 5000 1.0
Voltage transformer ratio. This ratio is
multiplied by the values measured in
the voltage and power measurements.
If no transformers are used, this value
must be set to 1.0.
Alarm End Timer Sec 0 255 20
When the alarm cause is removed, the
alarm ends after this duration unless it
is latching type.
Phase Order Check - 0 1 0
0: phase order not checked
1: alarm occurs if phase order is faulty.
Low Voltage Alarm V 0 65000 0
If one of the phase voltages drops
below this value, the unit concludes that
mains power is lost.
If this value is set to 0, it is not checked.
High Voltage Alarm V 0 65000 0
If one of the phase voltages exceeds
this value, the unit concludes that mains
power is faulty.
If this value is set to 0, it is not checked.
Voltage Fault Delay Sec 0 255 30
If phase voltages are outside the limits
for this duration, the unit concludes that
mains power is faulty.
Voltage Alarm Latching - 0 1 1
0: non-latching
1: latching
Low Frequency Alarm Hz 0 400 0
If the mains frequency drops below this
value, an alarm occurs.
If this value is set to 0, the alarm is not
checked.
High Frequency Alarm Hz 0 400 0
If mains frequency exceeds this limit, an
alarm occurs.
If this value is set to 0, the alarm is not
checked.
Frequency Alarm Timer Sec 0 255 30
