5.4 Soft Start Timer
The soft start timer is used to start a process at a reduced setpoint and power. The soft start
setpoint is used as a threshold only and is not a control point.
Example:
Main Setpoint = 800°C
Max power limit = 75% (This maybe set at the factory)
Soft Start Setpoint = 600°C (Threshold)
Soft Start Power Limit = 50% (Cannot be set above max power Limit)
When the timer is running the maximum power is controlled by the Soft Start Setpoint of
600°C and the Soft Start Power limit of 50%, this will continue until the timer ends or the PV
(Process value) exceeds the Soft Start Setpoint.
When the timer ends or the PV exceed the Soft Start Setpoint the instrument will start to
control using the main Setpoint of 800°C and the Max Power Limit of 75%.
