speed if it has been commanded to do so by a serial standby command. When Serial
enable is inacve and the R
S485/CAN/RS232 switch is in RS232 posion, the pump will
run at standby speed when the parallel standby line is acve.
In serial control mode, the state of the parallel Start line will be ignored but the serial
enable line provides an interlock funcon as shown in Figure: Serial and parallel control
owchart. This interlock funcon only operates with serial start commands and
therefore only in serial control mode. In serial control mode, the pump cannot be
commanded to standby speed by the standby line, instead a serial standby command
must be used.
The parallel normal and analogue output signals provide valid pump status informaon
at all mes under mixed parallel and serial operaon. The analogue output voltages are
described in Table: Logic interface technical data.

7.6 Operaon with a TIC or T
AG
The nEXT pump can be connected directly to an Edwards TIC Turbo Instrument
Controller, TIC Turbo Controller or TAG Controller.
Instrucons on the setup and operaon with the TIC Turbo Instrument Controller, TIC
Turbo Controller or TAG Controller can be found on CD ROM part number P450-00-000,
which is supplied with the TIC or TAG.
7.7 Decelerang and venng
Allow the pump to decelerate before venng.
