Hydraulic Output Signal
An optional hydraulic output signal is available on the
valve. An optional cam lobe on pilot valve #6 is used on the
camshaft assembly to initiate the hydraulic output signal
during regeneration or backwash (Figure 13). The
hydraulic line pressure signal is available through the
1/4-inch connection on the back of the valve marked
"AUX". See Figure 14. Remove the tube cap installed for
shipping.
Optional cam lobes available are:
P/N 1000554 Provides a hydraulic signal from the
beginning of BACKWASH through the start
of REFILL.
P/N 1000553 Provides a hydraulic signal from the
beginning of BACKWASH through the end
of REFILL.
P/N 1041064 Breakaway cam. Can be programmed to
send a hydraulic signal at any time during
the REGENERATION or BACKWASH cycle.
Note: The camshaft must be turning for
the signal to change states, i.e. switch
from OFF to ON, or from ON to OFF.

Magnum Tank Adapter
The tank adapter on the control valve is designed to be
compatible with a 4 inch-8UN (8 threads per inch) tank
opening. In addition, the adapter is designed to accept a
full 1-1/2-inch (3.81-cm) riser pipe with outside diameter of
1.90 to 1.91 inches (48.26 to 48.51 mm) (Figure 15). The
riser pipe is sealed by an O-ring on the inside of the tank
adapter (Figure 15). It is recommended that the riser pipe
extend beyond the top of the tank by 1/4 inch ± 3/8 inch (6
mm ± 9 mm).
Optional Switch Assembly
A single optional feedback switch kit is available to provide
an electrical signal during the entire regeneration or
backwash cycle (Figure 16). The switch may be wired in
the "Normally Open" or "Normally Closed" position and is
rated for 0.1 amp at 125 volts AC. An optional 5.0 amp
switch at 1/10 HP 125/250 volts AC is available upon
Optional Cam
request.
