speed if it has been commanded to do so by a serial standby command. When Serial
enable is inactive and the RS485/CAN/RS232 switch is in RS232 position, the pump will
run at standby speed when the parallel standby line is active.
In serial control mode, the state of the parallel Start line will be ignored but the serial
enable line provides an interlock function as shown in
flowchart. This interlock function 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 information
at all times under mixed parallel and serial operation. The analogue output voltages are
described in

7.6 Operation with a TIC or TAG

The nEXT pump can be connected directly to an Edwards TIC Turbo Instrument
Controller, TIC Turbo Controller or TAG Controller.
Instructions on the setup and operation 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 Decelerating and venting

Allow the pump to decelerate before venting.
