Wireless controlled Pro Force Debris Blowers (Models 44552, 44552TE, and
44553) use a Toro Electronic Controller (TEC) to manage machine electrical
functions. The TEC is a 2403 series microcontroller that monitors the condition
of various machine switches (inputs) and directs electrical power to control
appropriate machine functions (outputs) based on the state of the inputs. The
TEC works in conjunction with the Toro Wireless Modules (TWMs) to manage
power to the engine start relay and the nozzle control relays. The TEC also
manages power to the following Kohler engine components: governor control
unit, the fuel shut-off solenoid, and the ignition modules.
The TEC is attached to the machine control tower. Power for the TEC logic and
memory is available at all times (unswitched). The logic and memory circuit is
protected by a 2 Amp fuse (F−4). Power for the TEC outputs is available when
the main power relay is energized (key switch is in the ON or START position). A
pair of 7.5 Amp fuses (F−1 and F–2) protect the TEC output circuits.
