Setting the pump start delays

In the event that power to the SITRANS LUT400 has been lost, the pump start delay
ensures that all of the pumps do not start at once to avoid power surges. There are two
parameters used here: Pump Start Delay and Power Resumption Delay.
Example:
The delay between pumps is set to 20 seconds and the delay of the first pump is set to 60
seconds.
