Main power relay
The electrical system of the Pro Force Debris Blower uses 4 identical electrical
relays that have 5 terminals. A tag near the relay wire harness connector can
be used to identify each relay.
The main power relay is used to provide electrical power to the machine. When
the key switch is in the R
UN
or S
TART
position, the main power relay is energized.
The start relay is used in the engine starting circuit to provide a current path
to energize the engine starter solenoid. On machines with a wireless remote
(model 44552, 44552TE, and 44553) the start relay is energized by the TEC
when an engine start signal is received from the handheld remote, or when
the key switch is set to the S
TART
position. On machines with a tether control
box (model No. 44554) the start relay is energized when the key switch is set
to the S
TART
position.
The 2 nozzle relays are used for energizing the nozzle rotation motor. On
machines with a wireless remote (model 44552, 44552TE, and 44553) the relays
are energized by the TEC when a nozzle rotation signal is received from the
handheld remote. On machines with a tether control box (model No. 44554) the
relays are energized when the nozzle direction switch is pressed for nozzle
rotation.
The relays are secured to the rear of the machine control tower.
