RAMP-SOAK
This feature enables the controller to ramp up or down from
current temperature to a target setpoint at a pre-
determined rate. It then controls at the target setpoint for
an adjustable soak period before switching off the heat
output.

Notes
In Ramp on configuration, if power is removed from the
controller, the Ramp will re-start when power is restored.
The Ramp hold option suspends the ramp at its last value.
If no Soak period has been set, control at target setpoint
continues indefinitely.
SP2 deviation alarms follow the ramp setpoint and can be
used to alarm “out of limits” ramp rate.
WARNING
The Soak timer is triggered when the ramp setpoint reaches
the target setpoint. If the ramp rate is set too fast for the
process, the Soak timer will be triggered before the process
temperature reaches the target setpoint.
