alarm state.
Values:
l
Yes
- The alarm will be acknowledged, but the alarm
state may remain until the required conditions are met.
l
No
- The alarm is not acknowledged and the controller
remains in an alarm state.
Note: This parameter is also available when logged in at
Operator Level 1.
thld
Threshold
Only available if an "Absolute High" or "Absolute Low" alarm
has been configured. The desired alarm type must be
specified at the time of order.
Used to set the temperature threshold that will determine
when an alarm relay will activate for High (
Abs.H
)or Low
(
Abs.L
) alarms.
l
High - the alarm relay will activate when the tem-
perature exceeds the threshold value
l
Low - the alarm relay will activate when the tem-
perature drops below the threshold value
Note: If a deviation alarm is specified at time of order,
the
THLD
parameter will be replaced by the
DEV
(deviation) parameter.
Note: If more than one Absolute High and/ or Absolute
Low alarm is specified at the time of order, multiple
THLD
parameters will be available. They appear in the order
that the alarms were set up, so if Alarm 1 is an
AbS.H
,
and Alarm 2 is an
AbS.L
, the threshold value for the
AbS.H
alarm will be appear first when scrolling though
the parameter list.
DEV
Deviation
Only available if a Deviation alarm has been configured.
The desired alarm type must be specified at the time of
order.
Used to set the amount by which the temperature can
deviate from the Reference (
REF
) value (see section 9.0 for
more details on
REF
values).
l
Deviation High - The alarm relay will activate if the
temperature rises above the sum of the Reference and
Deviation values [
REF
±
DEV
], and will remain activated
until the temperature drops below the sum of the Refer-
ence and Deviation values minus any Hysteresis value
set [
REF
+
DEV
-
HYST
]
l
Deviation Low - The alarm relay will activate if the
temperature drops below the sum of the Reference and
