Other sensor arrangements are available including a floating sensor (called the
SLED
) for
cotton module feeder belt conveyors. Call the factory for more information.
During automatic moisture control, the PRIMARY TEMP CONTROLLER also has RSP
displayed in front of the setpoint temperature indicating that it is communicating with the
moisture control system. A setpoint (SP) is provided on the moisture control to allow the
ginner to bias the general drying temperature level upward or downward.
Raising the SP up on the moisture control will provide lower drying temperatures, while
lowering the SP will provide higher temperatures. A decal is provided on the face of the
moisture control as a reminder of the SP logic.
Notes:
A -
Use this arrangement for tower drying systems where both first and
second stage heater temperatures are adjusted automatically with the
moisture control.
B -
This arrange ment is used for Samuel Jackson drying systems using more
than one heater. One PRIMARY TEMP CONTROLLER is used for
measuring the temperature after a
dryer. Its SP temperature is
automatically adjusted by the moisture control as
before. The one
PRIMARY TEMP CONTROLLER adjusts the temperature RSP’s of each
of the heaters’ HIGH TEMPERATURE LIMIT CONTROLLERS.
