Section 1 - Introduction
General
The Network Terminal is used in multiple On-Board pump installations to
provide control of up to 20 pumps from a single point. The Terminal has a
built-in keypad and display that allows monitoring and control of any
pump on the network. The Network Terminal is available in two different
configurations; half panel and right hand panel as shown in Figure 1-1.
The Network Terminal can be connected to a host computer through the
Host RS-232 serial port so that the host can also address any pump on the
network. The Network Terminal also coordinates the use of roughing
valves in a specified group of pumps. This prevents cross contamination of
the pumps through the roughing lines during regeneration. On-Board
Pumps can be mapped together and the roughing valves in that map are
controlled through a token pass protocol. The Network Terminal allows
you to initiate regenerations simultaneously to two or more pumps. Refer
to Section 4 - Operation for more information.
NOTE: All personnel with installation and operation responsibilities
should become familiar with the contents of this manual to ensure high
quality, safe, and reliable Network Terminal performance.
On-Board NetLink Option
The Network Terminal can be connected to an On-Board NetLink
that allows On-Board Central Control (OCC) for Windows software to
communicate with multiple Network Terminals.
NOTE: The Network Terminal must either have the communication ports
or be upgraded to communicate with the On-Board NetLink. Refer to the
On-Board NetLink Installation, Operation, and Maintenance manual
