Alarms group prompts
Table 4-10 lists all the function prompts in the Alarms setup group and their definitions. These prompts
repeat for all 6 alarms.
TIP
To configure an alarm for a setpoint program segment event, program either type (AxS1TYPE
or AxS2TYPE) as EVENT. It is not necessary to configure any other alarm prompts.

Parameter Definition
AxS1 VAL
Value in engineering units
ALARM x SETPOINT 1 VALUE
— this is the value at
which you want the alarm type chosen in prompt
"AxS1TYPE" to actuate. The value depends on what the
setpoint has been configured to represent. NO setpoint
is required for Communications SHED. For SP
Programming the value is the segment number for
which the event applies.
AxS2 VAL
Value in engineering units
ALARM x SETPOINT 2 VALUE
— this is the value at
which you want the alarm type chosen in prompt
"AxS2TYPE" to actuate.
The details are the same as “AxS1 VAL”.

ALARM x SETPOINT 1 TYPE
— select what you want
Setpoint 1 of Alarm 1 to represent. It can represent any
of the Inputs, Relative Humidity, Deviation (loop 1 or 2),
Output (loop 1 or 2), and if you have a model with
communications, you can configure the recorder to
alarm on SHED. If you have setpoint programming, you
can alarm when a segment goes ON or OFF (loop 1 or
2).
An alarm can also be set to activate if a totalizer value
has exceeded a configured alarm value.
