6. Conguraon
Be
fore operang the pump, congure the motor controller sengs so that they are
suitable for the applicaon.
If the system is designed to operate with parallel control and monitoring, there is no
facility to change the majority of the motor controller sengs once the pump is installed
on the system.
The pump is supplied with all sengs at factory default values, as shown in Table:
Summary of commands that can be sent to the pump. If any of the motor controller
sengs are to be changed, change them before installing the pump on the system.
The pump can be congured using the customer serial comms over the serial interface.
Congure the pump using serial commands on page 66 details the commands that will
be needed to congure the motor controller. Alternavely use the Edwards TIC Turbo
and Instrument Controller, TIC Turbo Controller or TAG Controller. Further informaon
regarding this is detailed in Congure the pump using a TIC on page 74. The Edwards
nST2 PC soware can also be used to congure the pump, either via the serial interface
or via the USB service port.
Note:
The st
andby speed may be adjusted using the buon on the motor controller as
described in Standby speed seng on page 70.
If the pump is operated with parallel control and monitoring and the controller sengs
will not be recongured, go straight to Before starng the pump on page 75.
