The limit of the required High Temperature Alarm value can be entered in
currently selected units, in increments of 0.1 degree within the range of -19.9
°C to 70.0 °C. If a High Alarm occurs, and SSR output is assigned to the
High Temperature Alarm event (see Setion 6.4.13.5), the SSR output will be
activated when the Temperature reading is greater than the High
Temperature Alarm value.
The High Temperature Alarm condition is also indicated on the corresponding
Proess Information Screen by alternating every second between units of
measure and the “H” alert, meaning High.

The Temperature Alarm Action Delay is a time period in seconds that the
Temperature reading value may remain above the High limit or below the
Low limit before an Alarm condition is activated. Valid settings are in the
range of 0 to 3600 seconds. The default valus is 0: no delay.

Sometimes it is convenient to enable the Temperature Alarm only after a
specified power-up delay interval. The “Temperature Alarm Power On Delay”
option allows the user to set a specified time interval that will have to elapse
from the device power-up event before the Temperature Alarm function will
be activated. Valid settings are in the range of 0 to 3600 seconds. The
default value is 0: no delay.
