WIRING
Do not run thermocouple or other class 2 wiring in the same conduit as
power leads. Use only the type of thermocouple or RTD probe for which the
control has been programmed. Maintain separation between wiring of
sensor, auxiliary in or out, and other wiring. See the Initial Setting Menu for
input selection.
For thermocouple input always use extension leads of the same type
designated for your thermocouple.
For supply connections use No. 16 AWG or larger wires rated for at least 75˚
C. Use conductors only. All line voltage output circuits must have a common
disconnect and be connected to the same pole of the disconnect.
Input wiring for thermocouple, current, and RTD; and output wiring for
current 14 VDC is rated CLASS 2.
Control wiring as show below:

FRONT KEY FUNCTIONS
Key functions are as follows:
INDEX: Pressing the INDEX key advances the display to the next menu
item.
UP ARROW: Increments a value or changes a menu item. If pressed
during the Operation Mode, the set point value will be increased.
DOWN ARROW: Decrements a value or changes a menu item. If pressed
during the Operation Mode, the set point value will be decreased.
ENTER: Stores the value or item change. If not pressed, the previously
stored value or item will be retained. When pressed during the Operation
Mode, the controller switches to the Regulation Mode. If held for more
than 3 seconds during the Operation Mode, the controller switches to
the Initial Setting Mode. If pressed during the Regulation Mode or
Initial Setting Mode, the controller will return to the Operation Mode.
SECURITY FEATURES
The C series controller has two built in security lock settings to prevent
unauthorized personnel from changing parameter settings. These
parameters are set in the Operation Mode.
The LoC1 setting affects all parameters in the controller. If LoC1 setting is
enabled, the operator will have to unlock the controller to make any changes
to the controller’s parameters.
The LoC2 setting affects all parameters except the set point. If LoC2 setting
is enabled, the only parameter that the operator will be able to change is the
set point. In order to change any other parameters, the operator will have to
unlock the control before making a change.
In order to unlock the control, the operator must depress the ENTER and
INDEX key simultaneously.

PROGRAMMING AND OPERATION FOR PID
Theory of Operation
The PID method of control is based on the individual tuning of proportional
band values, integral time values, and derivative time values to help a unit
automatically compensate for changes in a control system. The proportional
band is the range around the set point in which the control’s proportioning
takes place. The control increases or decreases the output proportionately
to the process temperature’s deviation from the set point. The integral time
eliminates undershoot and overshoot of the set point by adjusting the
proportioning control based on the amount of deviation from the set point
during steady state operation. The derivative time eliminates undershoot and
overshoot by adjusting the proportioning control based on the rate of rise or
fall of the process temperature. The integral deviation offset correction (ioFn)
improves the speed in which the process value reaches the set point value.
If this parameter is set to zero, the output will be zero when the process
value is equal to the set point value. If the integral time parameter is used
only to eliminate steady state error, it may take a long time to reach the set
point because it needs time to accumulate the error. This parameter defines
the default output level on start up. When the integral time is set at 0, then
the proportional derivative offset correction (PdoF) would replace the integral
deviation offset correction, but serves the same function.
Program Set Up
In order to use the PID function in the C series controllers, the Control Mode
will have to be set to PID in the Initial Setting Menu. After changing the
Control Mode, the PID parameters can be accessed in the Regulation Menu.
The PID parameters can either be programmed manually or they can be set
by the controller using the auto tune function. The auto tune will use trial and
error to tune the PID parameters to give the control the most precise control.
Since the time to accurately tune the control may differ depending on the
process, the controller can also be manually tuned to known PID values
prior to running auto tune. The Run/Stop parameter must be set to run in
order to start auto tuning.

Verify that sensor is wired to proper
terminals. Next, check that the controller
is programmed for the correct input type.
Most commonly seen when controller is
programmed for a RTD, while a
thermocouple is connected.
Verify that the input is wired to the proper
terminals. Next check to see if the input
type is set to the proper value. Most
commonly seen when controller is
programmed for a 4 to 20 mA input and
0 to 20 mA signal is wired to the
controller.
Input signals may normally go above or
below range limits. If not check input and
correct the process temperature or
increase temperature range limits using
tP-H and tP-L.
Attempt to reset the factory default
settings using the instructions in the next
section. If still has error, call customer
service for a return goods authorization
number to have the controller evaluated
at the factory.
