24-Pump, 128-Station Controller Chapter 4: Operation 51
Chapter 4: Operation
4-1 Overview
Your 24/128 controller electrically controls valves and solenoids to convey material from a
central location to individual stations as needed. The controller senses demands for material
at the stations and responds to the demands in a timely fashion.
This section gives the procedures for using your controller, and it covers tasks that can be
carried out with no password or with an operator’s password. The section is divided into four
sub-sections:
• Starting and stopping the system
• Basic tasks: tasks normally carried out by a station operator
• Advanced tasks: tasks normally carried out by setup personnel
• Alarms: silencing and clearing alarms
Before you carry out any of the procedures in this chapter, the system must be set up as
described in the previous chapter.
4-2 Starting and Stopping the System
In an emergency, you can use the power switch on the upper right-hand side of the controller
cabinet if a password is required to stop the system and you do not know the password.
Normally, all the stations and pumps you want to use should be enabled before
you start the system. When the system is stopped, icons for enabled stations are
blue when full and dark yellow when they need material. Icons for enabled
pumps are blue. Enabling stations and pumps is described on p. 55.
A button to start and stop the system is located in the lower right of the Station Status, Pump
Status, and Alarm Log screens. When the system is off, the button is red and reads Push to
Start System. When the system is on, the button is green and reads Push to Stop
System. Depending on the setup at your facility, the system may prompt for a password
when you touch this button.
If conveying does not begin when you start the system, check to make sure that all needed
pumps are enabled. If they are, check that all needed stations are enabled.
