Wireless Remote Base Unit - Toro ProPass 200 Service Manual

Wireless Remote Base Unit (Machines with Electronic Hydraulic Controls)
The base unit is a solid state electrical device that re-
ceives signal inputs from the wireless remote and uses
those inputs to control machine electrical operation. The
base unit is attached to the front hopper wall next to the
hydraulic control manifold (Fig. 22).
Inputs from the wireless remote are monitored by the
base unit. Outputs from the base unit to the floor and
rear option (twin spinner or conveyor) solenoid valve
coils are controlled based on the inputs received by the
base unit.
NOTE: Use the wireless remote LCD display to make
sure that association exists between base unit and wire-
less remote (see Wireless Remote (Machines with Elec-
tronic Hydraulic Controls) in this section).
The base unit does not connect to an external computer
or hand held device, can not be re--programmed and
does not record any fault data.
Because of the solid state circuitry built into the base
unit, there is no reliable method to test it. The base unit
may be damaged if an attempt is made to test it with an
electrical test device, such as a digital multimeter.
IMPORTANT: To prevent damage to the base unit,
disconnect the wire harness connector from the
base unit before performing any welding on the ma-
chine.
LED Operation
Four (4) status/diagnostic LED's can be used to de-
termine the state of the base unit (Fig. 23).
The OUT LED will be green when an output is active.
This LED will be amber if there is an output issue. If this
LED is not illuminated, check the wireless remote LED's
and LCD display for correct remote operation.
The HEALTH LED will pulse green when communica-
tion between the base unit and the wireless remote is
functioning. If this LED is blinking amber, an internal
base unit problem exists. If this LED is blinking red, an
over temperature situation exists.
The TX/RX LED will be amber when the base unit is
communicating with the wireless remote. If this LED is
not illuminated, check for obstructions preventing line--
of--sight transmission with wireless remote and make
sure that wireless remote is active. It may be necessary
to re--associate the wireless remote with the base unit.
The POWER LED will be amber when power exists to
the base unit. If this LED is either red or green, an intern-
al base unit problem exists.
