CT Scale Amp rating of CT used (integer) AV3 Amps 0 30 Sets the size of the external 5-Amp CTs used. Range is 1 to
5999. E.g. for 10A:5A CTs, set register to 10; for 4000A:5A
CTs, set register to 4000.
Over Voltage (AV6) Alarm
Threshold
Alarm if L-L Voltage>threshold
> 10 sec
AV4 Volts 0 31 Occurs if the average L-L voltage (AI6) is greater than
this threshold for at least 10 seconds. Units are absolute
voltage (using integer multiplier). Range = 0 to 65535;
Default = 65535
Under Voltage (AV6) Alarm
Threshold
Alarm if L-L Voltage<threshold
(ever)
AV5 Volts 0 32 Occurs if the average L-L voltage (AI6) is less than this
threshold at any time. Units are absolute voltage (using
integer multiplier). Range = 0 to 65535; Default = 0
Over Current (AV8) Alarm
Threshold
Alarm if Avg Current>threshold
(ever)
AV6 Amps 0 33 Occurs if the average current (AI8) is greater than this
threshold at any time. Units are absolute current
(usinginteger multiplier). Range = 0 to 65535; Default
= 65535
Under Current (AV8) Alarm
Threshold
Alarm if Avg Current<threshold
(ever)
AV7 Amps 0 34 Occurs if the average current (AI8) is less than this
threshold at any time. Units are absolute current
(usinginteger multiplier). Range = 0 to 65535; Default
= 0
Over kVA (AV5) Alarm Threshold Alarm if kVA>threshold (ever) AV8 kVA 0 35 Occurs if the total apparent power (AI5) is greater than
this threshold at any time. Units are absolute kVA (using
integer multiplier). Range = 0 to 65535; Default = 65535
Under kVA (AV5) Alarm
Threshold
Alarm if kVA<threshold (ever) AV9 kVA 0 36 Occurs if the total apparent power (AI5) is less than this
threshold at any time. Units are absolute kVA (using
integer multiplier). Range = 0 to 65535; Default = 0
Meter Alarm Status (Latching) bitmap of 8 alarms - bits 9-15
are all 0
AV10 n/a 0 37 Holds the state of the meter alarm latches. These alarms
are latching and must be cleared by the user. To reset any
alarm, read the register and then write the register with
the desired alarm bit cleared. Writing a 1 to any bit has
no effect.
bit 0 = over current
bit 1 = under current
bit 2 = over kVA
bit 3 = under kVA
bit 4 = over voltage
bit 5 = under voltage
bit 6 = phase loss A
bit 7 = phase loss B
bit 8 = phase loss C
bits 9-15 = 0
Phase Loss Threshold Integer % of other phases AV11 Percent 0 38 Phase Loss Threshold (0 to 100%, default = 65535): these
exist independently for all 3 phases (A, B, C). This register
sets the alarm threshold for all three phases. This setting
is the percent deviation of a phase from the average of
all 3 phases (register 8). The decision logic is constructed
so that normal power-ups do not trigger alarms. A phase
loss alarm will occur only if the following conditions are
met:
1. The average L-L voltage (register 8) is greater than 25V.
2. The L-N voltage on a phase (register 20, 21, or 22) is less
than the percent deviation set by this threshold.
3. This threshold is set between 0 and 100%.
