6.7 Soft Start Timer

The timer is used to start a process at reduced power and/or reduced setpoint. Timing starts at power up or when ‘Run’

is selected.

When the Timer Status = Run, the controller power is limited by the soft start power limit parameter. The Soft Start

setpoint is a threshold which, when exceeded, sets the timer to end. If the temperature is already above this threshold

when the timer is set to run, the timer will time out immediately.

When the timer status = reset, the controller is controlling at SP1
