GETTING STARTED

1. Install the control as described on page 4.

2. Wire your control following the instructions on page 6. Please read the Precautions section located at the end of this manual before wiring the control.

3. For best results when programming changes are necessary, make all changes to the Initial Setting mode (Pages 13-14) before making changes to the Regulation Mode (Pages 11-12) or Operation Mode (Pages 10). If any error messages occur, check the Diagnostic Error Message Section (Page 18) for assistance.

INSTALLATION

Mount the instrument in a location that will not be subject to excessive temperature, shock, or vibration. All models are designed for mounting in an enclosed panel.

Select the position desired for the instrument on the panel. Prepare the panel by cutting and deburring the required opening per the panel cut out dimensions listed below. Follow the mounting instructions listed on page 5. Lastly, wire the controller per the appropriate wiring diagram listed on page

MOUNTING METHOD

Step 1: From the front of the panel, slide the controller housing through

the cut out. The housing gasket should be against the housing flange before installing.

Step 2: Insert the mounting brackets into the mounting grooves on the

top and bottom of the controller (4C, 8C, and 16C).

Step 3: Push the mounting brackets forward until the bracket stops at

the panel wall.

Step 4: Insert and tighten the screws on the bracket to secure the

controller in place. (The screw torque should be 0.8 kgf-cm).

RTD

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.

CONTROL OPERATION DESCRIPTION

The HOME display is the normal display while the control is operating. If no errors or functions are active, the HOME display will indicate the Process Variable that is being measured on the top display and the Set Variable on the bottom display.

Error Messages are shown on page 18.

Heating or Cooling

Temperature Control can be achieved by either heating or cooling. Please refer to the following for the operation of each setting.

Control Modes are selected by changing the S-HC parameter in the Initial Setting Mode.

Select HEAt, for heating or reverse acting control for output 1.

Select CooL, for cooling or direct acting control for output 1.
