3.6 Electrical data
The pumps can be operated by the customers system or by the manufacturer's TIC Turbo
Instrument Controller or TIC Turbo Controller.
If using the customer system, the size of the power supply depends on the application.
The rate of increase in the pump speed is dependent on the power limit setting. The
power limit setting overrides the necessary power supply setting. If the serial
communications or an access to the manufacturer's TIC is available, the power limit
setting of the pump can be selected. Refer to
Table: Logic interface technical data on
for the maximum power limit settings for the pumps. If the rapid cycling of the
pump is necessary for an application, you can get the faster rate of increase in the pump
speed if the power supply supplies higher current, up to a maximum in accordance with
Table: Logic interface technical data on page 27
.
