Alarm Outputs
Alarm Types
The Bulletin 900-TC8 supports up to three alarm outputs, Bulletin 900-TC16
supports two alarm outputs, and Bulletin 900-TC32 supports one alarm
output..
The controller alarm output conditions are determined by the combination of
the selected Alarm Type, Alarm Value, Alarm Hysteresis, and Set Point (SP)
parameters.
Alarm types are configured independently for each alarm output using the
Alarm 1 and Alarm 2 Type parameters (Initial Setting function group).
Note:
The default Set Value is 2: Upper-Limit (deviation).
Configure the alarm type and alarm output operation based on pre-defined
conditions using the Set Value number.
Note:
The following table describes the Alarm Type, Alarm Value,
Upper-Limit Alarm, and Lower-Limit Alarm parameters.
