Edwards nEXT730D - Operation with a TIC or TAG; Decelerating and Venting

speed if it has been commanded to do so by a serial standby command. When Serial
enable is inacve and the R
S485/CAN/RS232 switch is in RS232 posion, the pump will
run at standby speed when the parallel standby line is acve.
In serial control mode, the state of the parallel Start line will be ignored but the serial
enable line provides an interlock funcon as shown in Figure: Serial and parallel control
owchart. This interlock funcon 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 informaon
at all mes under mixed parallel and serial operaon. The analogue output voltages are
described in Table: Logic interface technical data.

7.6 Operaon 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.
Instrucons on the setup and operaon 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 Decelerang and venng
Allow the pump to decelerate before venng.
