The parallel normal and analogue output signals gives valid pump status information at
all times under mixed parallel and serial operation. The analogue output voltages are
given in Table: Logic interface technical data on page 27 .

6.5 Operation with a TIC
For operation with the manufacturer's Turbo Instrument Controller or
TIC Turbo Controller, the pump can be connected to this type of unit, which gives the
power necessary to drive the pump. Instructions on the setup and operation with the
TIC or TIC Turbo Controller can be found on CD ROM part number D39700879 which is
supplied with the TIC or TIC Turbo Controller.
6.6 Decelerating and venting
Switch off the backing pump immediately after applying the stop command (by the
parallel or serial interface or by the TIC). The system can be vented in accordance with
the advice given in Vent options, vent valve connection and control on page 52 .
CAUTION: RATE OF INCREASE IN PRESSURE
Risk of damage to equipment. Do not open a manual vent valve until the pump
rotational speed decreases below 50%, otherwise the rate of increase in pressure can
be too high, which can damage the pump. In an emergency, open the vent valve
quickly to decelerate the pump rotor in the shortest possible time.
