2–Pump 12-Station Controllers Chapter 3: Installation 17
Main Power
Your 12-station controller system can operate from a 115 VAC or 220 VAC source at 50 Hz
or 60 Hz. The main power switch on the controller is located on the right side of the housing.
Built into the power switch are the controller fuses. Also, the configuration of the fuse holder
determines the voltage setting of the controller (115/220 VAC).
Marked on the faceplate of the fuse holder shows the configuration for the desired voltage.
Using a small screwdriver, remove the fuse holder. To select the operating voltage, align the
arrow marker on the holder and the switch as shown in the following section.
The 12 station controller has a standard IEC power cord. Plug the cord into any standard 115
VAC outlet. If you selected the 220 VAC option, remove the end connector and install a
standard 220 VAC plug. Doing so does NOT effect the controllers warranty.
DC Controller Power Sources
Although main controller power is 115/220 VAC, control power is actually unregulated 24
VDC. The 24 VDC control power supplies the power for all solenoids, sensors, and the
controller itself. The unregulated supply can deliver up to five (5) amps of continuous current
to drive a very large system.
Inputs
• Station connections
• High vacuum connections
• System error connections
Outputs
• Station connections
• Pump/blowback
• Spare
3-4 Setup
This section provides the procedures for configuring your 2-pump, 12-station controller.
Configuration of your controller includes setting the number of stations and pumps, setting
variables such as convey time and blow-back interval, and setting up passwords. We
recommend that you carry out these procedures in the order given here.
Note: Before carrying out these procedures, install all equipment as
described in this section and in the Mechanical Components manual.
To help you set up the controller quickly, this section walks you through the setup using the
menu system. This procedure will work for most applications, but you may need to perform
some minor adjustments afterwards to achieve the best conveying performance.
Note: The controller must be in Offline mode to permit access to the menu
system.
