High Process Alarm Setpoint
Use this menu to select the setpoint (temperature or other value within
the scaled sensor range) at which the high process alarm activates. The
high process alarm activates when the process variable (PV) goes above
the high process setpoint. It deactivates when the PV goes below the
high process setpoint minus the deadband value, if you have set a
deadband value.
Selectable range: Any point within the scaled sensor range.
High Process Alarm Type
Use this menu to turn off the high process alarm or set it to the alarm or
control function.
Selectable values: Alarm, Control, Off.
High Process Alarm Output Number
Use this menu to choose the digital output that activates when the loop
is in high process alarm. You can use this output to activate a second
alarm horn or buzzer. You can also use it to control your process. For
example, you can set the output you have chosen to activate heating or
cooling mechanisms, or to turn off the system.
Selectable values: Any output number between 1 and 34, as long as it’s
not already used for control or the SDAC clock. You may also select
NONE.
