GND CURR
HHALARM When there is no TRIP function enabled, the second
level higher ground/earth leakage current alarm will au-
tomatically clear when the second high ground/earth
current alarm event clears. This event is reported as
a GND CURR HHALARM (high-high alarm).
LOW AMPS
ALARM The amperage being read on this circuit is below the
value programmed as the lowest heater operating cur-
rent allowed before an alarm condition is reported.
HIGH AMPS
ALARM The amperage being read on this circuit is above the
value programmed as the highest heater operating cur-
rent allowed before an alarm condition is reported.
When there is no TRIP function enabled, the first level
heater operating current alarm setting will automatically
clear when the high heater current alarm event clears.
This event is reported as a HIGH AMPS ALARM.
HIGH AMPS
TRIP The amperage being read on this circuit is above the
value programmed as the highest heater operating cur-
rent allowed before a TRIP condition is reported. When
the amperage exceeds the TRIP level, the condition
must be ACKNOWLEDGED and the heater operating
current level must drop below the TRIP set point value
before the circuit will re-energize.
HIGH AMPS
HHALARM When there is no TRIP function enabled, the sec-
ond level higher heater current alarm will automati-
cally clear when the second higher heater current alarm
event clears. This event is reported as a HIGH AMPS
HHALARM (high-high alarm).
CKT FAULT
ALARM A circuit fault condition is reported if during the SELF
TEST procedure of energizing each circuit, it is deter-
mined that the heater current does not change between
the ON and OFF states.
GND FAULT
ALARM A ground fault condition is reported if during a TRIP-
TO-TEST procedure of applying a test leakage current
to each circuit, it is determined that the test leakage
current is not sensed.
