LPH800 TREATER
1. PUMP #1 VOLTMETER:
Displays the DC voltage for pump #1. As pump #1 speed
is increased or decreased, this number will also increase or decrease.
2. HAND / OFF / AUTO SWITCH (for Pump #1 & #2):
This switch controls pump #1,
pump #2, and any device connected to the auxiliary port. This switch must be
activated before either pump will operate in forward or reverse.

HAND POSITION:
When the switch is placed in HAND, the pump(s) will run only
when you have turned the pump(s) switch to forward or reverse and the speed has
been adjusted.

AUTO POSITION:
When the switch is placed in
AUTO, the pump(s) will only run when the lower
proximity switch located in the supply hopper is
covered and the atomizer is running. The proximity
switch determines when seed is present in the
hopper. When the proximity switch does not detect
seed, a timer relay located inside the control panel
will automatically shut off the pump(s) a pre
-
determined amount of time after the hopper has
emptied. The timer relay (right) located in the control
panel is set to Mode “D” and has an adjustable knob
with settings from 0
-
6. Each number represents the
number of seconds from the time the hopper empties
until the pumps will shut off. The time delay allows
all seed in the hopper to have an equal coverage.
3. PUMP #1 DIRECTION:
This switch allows the operator to change the pump
direction between forward and reverse. It has a safety feature that will not allow the
operator to switch from forward to reverse or vice
-
versa without momentarily stopping
and releasing the switch in the center position.
4. LIQUID ADJ. PUMP #1:
This dial allows the operator to adjust the speed of
pump #1. The setting should be chosen in relation to the application rate for the
treatment being applied to the seed.
5. PUMP #2 VOLTMETER:
Displays the DC voltage for pump #2. As pump #2 speed
is increased or decreased, this number will also increase or decrease.
6. PUMP #2 DIRECTION:
This switch allows the operator to change the pump
direction between forward and reverse. It has a safety feature that will not allow the
operator to switch from forward to reverse or vice
-
versa without momentarily stopping
and releasing the switch in the center position.
7. LIQUID ADJ. PUMP #2:
This dial allows the operator to adjust the speed of
pump #2. The setting should be chosen in relation to the application rate for the
treatment being applied to the seed.
