400.6 Goyen T-4 and P-4 Automatic Timer Controller
The T-4 Automatic Timer Controller uses a solid-state timer control to continuously clean the cartridges
with the user inputting the length of pulse and the interval between pulses. The P-4 Automatic Timer
Controller uses a differential pressure transmitter connected to a solid-state timer control to initiate the
cleaning cycle at user input differential pressure set points. When the differential pressure across the
filter elements reaches the high set point, the control will begin the cleaning sequence until the low
differential pressure set point is obtained. The control will then end the cleaning cycle until the high set
point is reached again. At this point, the controller will re-initiate cleaning, beginning with the next to last
row cleaned.
Installation
Connect Line Input Power, AC voltage to the terminals marked L1 and L2, DC voltage to the Negative (-)
and Positive (+) terminals.
Connect the output terminals to the pilot valve solenoid coils. Connect common side of the coil, AC
voltage to terminal L2, DC voltage to the Positive (+) terminal. Note: Line voltage must match coil voltage.
Blowdown: If the blowdown feature is used, disconnect the jumper between terminals B1 and B2 and
connect them to the auxiliary contacts on the fan motor starter. The contacts are to open when the fan is
stopped.
Ground: Connect the circuit ground to the green terminal. Ground the control enclosure separately using
the grounding stud inside the box.
Connect the high and low pressure taps on the bottom of the control housing to the collector pressure
taps, using ¼” diameter metal or other tubing (not provided). The “high” tap connects to the “dirty” side of
the tube sheet and the “low” to the “clean” side.
