5. Configuration
Before you operate the pump, configure the motor controller settings that are applicable
for the application.
If the system is designed to operate with parallel control and monitoring, you cannot
change the motor controller settings when the pump is installed on the system. The
pump is supplied with the settings at factory default values, as shown in Table: Summary
of commands that can be sent to the pump . If you want to change the motor controller
settings, change the settings before you install the pump on the system.
To configure the pump, use one of the methods that follow:
▪ Use the customer serial comms over the serial interface to configure the pump.
Refer to Configure the pump using serial commands on page 62 for the necessary
commands to configure the motor controller.
▪ Use manufacturer's TIC Turbo and Instrument Controller, TIC Turbo Controller or
TAG Controller.
Refer to Configure the pump using a TIC on page 69 for more information.
▪ Use manufacturer's nST PC software to configure the pump through the serial
interface or through the USB service port.
Note:
Use the button on the motor controller to adjust the standby speed. Refer to
Standby speed setting on page 65.
If the nEXT pump is operated with parallel control and monitoring and the controller
settings will not be configured again, refer to Before starting the pump on page 71.
5.1 Configure the pump using serial commands
Refer to Table: Summary of commands that can be sent to the pump for the summary of
the serial commands, parameter ranges and factory defaults for each setting. Refer to
the sections that follows for more information about settings.
5.1.1 Message structure
The message structure and command set are same for RS485 and RS232 options. To
send a message to the pump, the characters must be sent in a specific order. If the
message is in incorrect structure it will be ignored and no reply will be sent.
The correct structure is as follows:
▪ a valid start character
▪ a '!' character for a store operation or
▪ a '?' character for a query operation, followed by
▪ a command: an upper case alphabetical character, followed by
▪ an object number: has three decimal digits, followed by
▪ a data field (for some commands only,): has a sequence of characters separated
from the object number by a space, followed by
▪ a terminating carriage return.
