Edwards nEXT nEXT85 - Operation with a TIC or TAG; Decelerating and Venting; Figure 22 Serial and Parallel Control Flowchart

▪ RS485/RS232 switch is in RS232 posion and
▪ 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 gives an interlock funcon as shown in Figure: Serial and parallel control
owchart on page 77. This interlock funcon only operates with serial start commands
and in serial control mode only. 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 give valid pump status informaon at all
mes under mixed parallel and serial operaon. The analogue output voltages are given
in Table: Logic interface technical data on page 25.

6.6 Operaon with a TIC or TAG
The pump can be connected to manufacturer's TIC Turbo Instrument Controller, TIC
Turbo Controller or TAG Controller. The TIC gives the power necessary to operate the
pump, but the TAG requires a separate PSU to be connected.
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.
6.7 Decelerang and venng
Decelerate the pump before venng.
