Alarm Types
Each alarm can be independently set to one of the following 17 alarm types. The default is 2: Upper limit. (See note.)
Auxiliary outputs are allocated to alarms. ON delays and OFF delays (0 to 999 s) can also be specified.
Note: In the default settings for models with HB or HS alarms, alarm 1 is set to a heater alarm (HA) and the Alarm Type 1 parameter is not displayed.
To use alarm 1. set the output assignment to alarm 1.

1 Upper- and lower-limit *1 *2
Set the upward deviation in the set point for the alarm upper
limit (H) and the lower deviation in the set point for the alarm
lower limit (L). The alarm is ON when the PV is outside this
deviation range.
2
(default) Upper-limit
Set the upward deviation in the set point by setting the alarm
value (X). The alarm is ON when the PV is higher than the
SP by the deviation or more.
3 Lower-limit
Set the downward deviation in the set point by setting the
alarm value (X). The alarm is ON when the PV is lower than
the SP by the deviation or more.
4 Upper- and lower-limit
range *1 *3
Set the upward deviation in the set point for the alarm upper
limit (H) and the lower deviation in the set point for the alarm
lower limit (L). The alarm is ON when the PV is inside this
deviation range.
5 Upper- and lower-limit with
standby sequence *1 *4 A standby sequence is added to the upper- and lower-limit
alarm (1). *6
6 Upper-limit with standby
sequence A standby sequence is added to the upper-limit alarm (2). *6
7 Lower-limit with standby
sequence A standby sequence is added to the lower-limit alarm (3). *6
