MANIFOLD WIRING HARNESS
(See Figure 30)
The manifold wiring harness provides electrical
connections for the manifold valve block (solenoids
PF1 and PF2), the electronic control box cable, the
CAN receiver, temperature sensor and the power
supply cable. Electrical power is only present in the
manifold harness when the Power ON/OFF switch is
in the “ON”.
Temperature Sensor (See Figure 30)
The temperature sensor is located in the upper section
of the block in port “EX”. The sensor is a temperature
activated normally open switch. The sensor monitors
the hydraulic fluid temperature as it enters the top
dresser from the truck. The sensor wires are -
● The red wire in the connector is “TEMP POWER IN”
and provides positive (
+
) power to the sensor. The
wire will only have voltage (
+
) present when the
Power ON/OFF switch is in the “ON” position.
● The blue wire in the connector is “TEMP POWER
OUT” and goes to pin 11 on the gray CAN receiver
connector. The wire is positive (
+
) and provides
power for the high temp warning signal. The
wire will only have voltage (
+
) present when the
Power ON/OFF switch is in the “ON” position and
the temperature of the hydraulic system is 205°F
degrees (96°C) or higher.
With a temperature over 205°F degrees, the message
“HIGH HEAT - SHUTDOWN!” will flash on the control
box display. The warning will appear for at least 15
minutes. If the temperature has not lowered to a
safe level, the sensor will continue the warning in 15
minutes increments until the temperature has reached
a safe level under 205°F. The power switch must be
On to power the control box to keep the 15 minute
cycle active. If the power is off, the 15 minute cycle will
restart as of when the power is returned.
The sensor
WILL NOT
shut down the system, the
operator must stop the top dresser and allow the trucks
hydraulics to cool down. If the sensor has failed, it will
not keep the top dresser’s hydraulics from operating
- the sensor only monitors the fluid temperature level
coming from the truck.
Manifold Connector
-
PF1 Solenoid (Figure 30)
The PF1 solenoid coil controls the operation of the
spinner speed hydraulic valve. PF1 is located on the
upper section of the hydraulic manifold. The wires in
the PF1 connector are -
● The orange wire in the connector is “SPINNER
PF1” and plugs into solenoid coil PF1. The orange
Spinner PF1 wire is positive (
+
). The wire is power
to the solenoid coil and routes back to the pin 1 in
the black CAN receiver connector.
● The black wire in the connector is negative (
-
)
ground for the PF1 solenoid coil. The ground wires
route back into the harness, is joined to other ground
wires.
The Power ON/OFF switch must be in the “ON” position
and electronic control box switch must be in the “ON”
position for the spinners to test for voltage at solenoid
coil PF1. When the solenoid is activated, it controls the
PF1 valve in the manifold block and controls hydraulic
flow to the spinner hydraulic motors which controls
motor speeds. Amperage levels will change in relation
to the speed settings (%) shown at the control box.
Manifold Connector - PF2 Solenoid (Figure 30)
The PF2 solenoid coil controls the operation of the
conveyor belt speed hydraulic valve. PF2 is located
on the lower section of the hydraulic manifold. The
electrical connection is -
● The tan wire in the connector is conveyor “BELT
PF2” and plugs into solenoid coil PF2. The tan Belt
PF2 wire is positive (
+
). The wire is power to the
solenoid coil and routes back to the pin 2 in the
black CAN receiver connector.
● The black wire in the connector is negative (
-
)
ground for the PF2 solenoid coil. The ground wires
route back into the harness, is joined to other ground
wires.
The Power ON/OFF switch must be in the “ON”
position and electronic control box switch must be in
the “ON” position for the spinners and conveyor belt to
test for voltage at solenoid coil PF2. When the solenoid
is activated, it controls the PF2 valve in the manifold
block and controls hydraulic flow to the conveyor belt
hydraulic motor which controls motor speed. Amperage
levels will change in relation to the speed settings (%)
shown at the control box.
