Starting the Unit—Auto Start Diesel
Operation
Auto Start is included with the cab control box.
1. Place the Diesel/Electric switch in the Diesel
position and place the power receptacle
On/Off switch in the On position.
2. Place the control box On/Off switch in the On
position.
3. Press the
O
N
key in the cab control box.
4. The unit should preheat and start
automatically. If the unit fails to start, press
the
O
FF
key and place the On/Off switches in
the Off position. Determine and correct the
cause of the failure. Push in the reset button
and repeat the starting procedure.
NOTE: The Auto Start system, included with
the cab control box option, functions like the
CYCLE-SENTRY system except that once
started the unit does not shut down on
thermostat demand. The unit runs
continuously until it is turned Off manually.
The start sequence, once initiated, is the
same for both systems. Refer to the
CYCLE-SENTRY sections of this manual for
further information on the start sequence, as
it applies to the Auto Start system.

The Thermo King CYCLE-SENTRY system is
designed to save refrigeration costs. The savings
vary with the commodity, ambient temperatures
and truck insulation. However, not all temperature
controlled products can be properly transported
without continuous air circulation.
