Each trigger can be defined as a high or low setpoint. Additionally, an optional deadband value can
be set. A deadband prevents the trigger from rapidly changing between active and inactive states
when the measurement value is near the setpoint. Refer to Figure 15.

Option Description

the setpoint trigger becomes active. The program starts when the delay time expires.
Note: Setpoint control and delay options are global settings that are applied to all triggers.
