Chapter 4: Operation
4-1 Overview
Your 7/50D Plus or 7/50D 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
•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
Note: 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
Note: 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 yellow when they need material. Icons for enabled pumps are yellow. Enabling stations and pumps is described on p. 60.
A button to start and stop the system is located in the lower right of the Station Summary, Pump Summary, 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.
Note: 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.
