tion, their overload protective switches should be con-
nected in series and then connected into the dryer
safety circuit. For recommended connections, refer to
motor overload protection connections shown in the
SAFETY CIRCUIT portion of the control circuit wiring
diagram in Section 8.

NOTES:
1. The motor current and maximum dryer running loads listed
above are based on auxiliary conveyor motor sizes shown.
The maximum size motor that can be powered directly through
the dryer's ASC control is listed in the Aux. Motor Data chart.
All larger than maximum auxiliary conveyor motors require
separate contactors and overload protectors with coil circuits
connected to the dryer for automatic operation.
IMPORTANT: All standard Model C-2100A dryers are factory
equipped with overload relay heater elements sized for auxil-
iary motors listed in charts above. If the actual auxiliary motors
used are of a different size, the elements must be changed.
2. Auxiliary motors are controlled by the top and bottom auger cir-
cuit breakers.
