Imer Control; Olenoids - Farr Gold Series Installation, Operation And Maintenance Manual

330.2 Timer Control
This discussion refers to standard equipment that uses 120/220 VAC, single phase, 50/60 Hz power.
Refer to your General Dimensions drawing to confirm the electrical requirements of your equipment.
Connection instructions are the same regardless of the voltage source. Refer to the documentation
attached to this manual and the timer control box for further information regarding the installation of your
specific control.
If equipped, mount the Automatic Timer Control on a wall or stand close to the collector. It is important to
mount the timer near the collector so that you can monitor the performance. Keep in mind that both
pressure gage and electrical connections need to be made to the timer control. Note: Do not mount the
timer control to the dust collector! Vibration from the pulsejets may damage the sensitive
electronic equipment.
330.3 Solenoids
To wire your solenoids, follow Figures 330.1 and 330.3.1. Each solenoid will have two wires attached –
one specific for the numbered row of cartridges and a second wire that will be attached to all of the
solenoids (called the Common). The Common is factory pre-wired on the solenoids, therefore only one
connection will need to be made. Once the solenoid has been wired, the corresponding wires will then be
attached to the control board as shown in Figure 330.3.2. The Common will share a terminal with the L2
terminal (120 volt "return" power line). Note: The Controllers will have a separate Common
connection terminal on the board; this terminal is internally connected to the L2 power terminal
and has the same effect as wiring into the L2. Connect the first wire (other than the Common) from a
solenoid on a row of cartridges, to the corresponding numbered terminal on your control board. Once this
is done for all of the rows, you can connect the L1 and L2 Terminals (L1 is "Hot", L-2 is "Return") to your
120-volt power source. For more information on the diaphragm and solenoids see the attached
specification sheets.
