When more than one Heater is used in a Samuel Jackson drying system, it is common to
have one after mix temperature controlling the before mixpoint set points of all the
Heaters. The “HEATER 1”, “HEATER 2”, etc. buttons are referring to which Heater is
connected to the after mixpoint thermocouple. Heater 1 will have its network ID set for
Heater number 1 by the setting of the DIP switches on its Ethernet port card on the
Heater’s PLC.
Network ID number settings for Heaters 1 – 8 are shown on the drawing titled
“
NETWORK ID SETTING FOR VULCAIN OIL-FIRED HEATERS
” included in this
manual.
Go back to the ANALOG SOURCE setup screen by pressing the
button. Press the
“AFTER-MIX SET-POINT” button. If no automatic dryer temperature control is
available, the ginner (user) will set the after mixpoint temperature. This is activated when
the “USER SP” button is green.
If the Moisture Mirror X is used with an incoming moisture sensor, then select “MMX
BANK-1” button. The BANK-2 and BANK-3 buttons are used when multiple stages of
Heaters are connected and the user wants the temperatures to be different between the
stages.
For example, more heat for collision air and less heat for the Hot Box pickup for a
Samuel Jackson Collider Drying System may be desirable. The percentage of difference
between the banks is set on one of the additional settings screens accessed from the
INCOMING MOISTURE screen of the Moisture Mirror X.
Go back to the ANALOG SOURCE setup screen by pressing the
button. Press the
“BEFORE-MIX SET-POINT” button. On this screen, normally the “AM CONTROL”
button is selected and will be green. This means that the before mixpoint temperature is
set automatically based on the after mixpoint control. This is the default setting.
As the actual after mixpoint temperature changes based on incoming cotton moisture
conditions, the before mixpoint temperature setpoint is automatically changed to maintain
the desired after mixpoint temperature. This temperature control logic has been a
standard on Samuel Jackson Heaters for a number of years.
After-Mix Set-Point Setup Screen
The “USER SP”
button is green when
the ginner sets the
after mixpoint
temperature.
One of the BANK
buttons will be green
when a Moisture Mirror
X is automatically
controlling the set point
temperature.
