3.10 Changing the start delay time
Generally it will make sense to let the turbomolecular pump
run up immediately after applying the start command.
However when operating two or more turbomolecular
pumps off a single power supply unit, it may make sense to
start the pumps one after the other. One way of achieving
this is to enter a start delay time differing from 0.
To set up the start delay time proceed as follows:
With the aid of a Windows PC and the PC software
“TURBO. DRIVE Server” change the setting for the parame-
ter 36 “Start delay time”. The possible values for parameter
36 can be varied within the limits of 0 to 25.5 minutes (0 to
255).
So as to retain the value saved for parameter 36 when
switching the pump off, the parameter value needs to be
saved permanently. For this enter any value (for example 1)
for parameter 8. Thereafter changed parameters will be
saved permanently.
