ALARM TYPE AND ACTION
Caution: In any critical application where failure could
cause expensive product loss or endanger personal
safety, a redundant limit controller is required.
When setting the alarm value for a deviation alarm (
A1t
=
dE
or
A2t
=
dE
), set the difference in value from the Set
Point (
SP1H
) desired.
Since the input for the MPC is driven from a transmitter,
the input display can be programmed in different ways.
Regardless of the position of the decimal point, a change
of one in the right most digit is referred to as a count.
For example, if there were no decimal point selected, a
change from 235 to 236 is a change of one count. If the
decimal point were selected at
0.0
, a change of 23.5 to
23.6 is a change of one count.
When setting up an alarm for deviation the deviation is
set in counts. For example if a low alarm is required to
be 5 counts below the
SP1H
, then set
A#Lo
to -5. If a high
alarm is required 20 counts above the
SP1H
, then set
A#Hi
to +20. If
SP1H
is changed, the alarm will continue to hold
the same relationship as originally set.
When Alarm Power Interrupt,
A#P
, is programmed ON
and Alarm Reset,
A#rE
, is programmed for Hold, the
alarm will automatically reset upon a power failure and
subsequent restoration if no alarm condition is present.
If Alarm Inhibit,
A#iH
is selected ON, an alarm condition
is suspended upon power up until the process value
passes through the alarm set point once. Alarm inhibit
can be restored as if a power up took place by pressing
both the
INDEX and ENTER keys for 5 seconds.

IF INHIBIT IS ON AND A POWER
FAILURE OCCURS DURING A

CAUSE THE ALARM TO OCCUR IF THE PROCESS
VALUE DOES NOT FIRST DROP BELOW THE HIGH
ALARM SETTING. DO NOT USE THE ALARM INHIBIT
FEATURE IF A HAZARD IS CREATED BY THIS
ACTION. BE SURE TO TEST ALL COMBINATIONS OF
HIGH AND LOW ALARM INHIBIT ACTIONS BEFORE
PLACING CONTROL INTO OPERATION.
WARNING

absolute alarm (
A1t
=
AbS
or

=
AbS
), simply set the value at which
the alarm is to occur.
