D**ALARMS**
01 ALARM STATUS (monitor)
The status shows TRUE when an alarm is active.
02 FIRST ALARM (monitor)
This will display a message of possible alarm conditions:
o
NO ALARMS
o
ANALOG INPUT #1 FAIL
o
ANALOG INPUT #2 FAIL
o
LOAD SENSOR FAIL
o
LOAD SHARE LINE FAIL
03 ANALOG INPUT #1 FAIL (monitor)
When TRUE indicates a signal input failure.
Analog Input #1 will indicate a failure if the following conditions exist:
Set for 4
–20 mA, 2 mA > value < 22 mA
Set for 1
–5 Vdc, 0.001 Vdc > value < 5.5 Vdc
Set for ±2.5 Vdc,
–2.73 Vdc > value < 2.73 Vdc
04 ANALOG INPUT #2 FAIL (monitor)
When TRUE indicates a signal input failure.
Analog Input #2 will indicate a failure if the following conditions exist:
Set for 4
–20 mA, 2 mA > value < 22 mA
Set for 1
–5 Vdc, 0.001 Vdc > value < 5.5 Vdc
Set for ±2.5 Vdc,
–2.73 Vdc > value < 2.73 Vdc
05 LOAD SENSOR FAIL (monitor)
When TRUE indicates a load sensor failure.
A Load Sensor failure is indicated when the CT current drops below
–0.15 mA.
06 LOAD SHARE LINE FAIL (monitor)
When TRUE indicates a load share line failure.
07 RESET ALARMS dflt = FALSE (FALSE, TRUE)
This switch resets the alarm status.
