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 6.
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 (16B, 8B, and 4B). For the 32B, slide the mounting collar over the housing from the rear of the panel. Step 3: Push the mounting brackets forward until the bracket stops at the panel wall.
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.

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.
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 (the temperature, pressure, flow, %RH, etc.) that is being measured on the top display and the Set Variable on the bottom display. Items that can change the HOME display are the Ramp and Soak function and any error messages. Descriptions of these special displays follow.
Heating, Cooling or Dual Loop Control Temperature Control can be achieved by either heating or cooling. In the B series controllers, heating and cooling can be operated simultaneously using Dual Loop Output Control to maintain a temperature set point. When Dual Loop Output Control is used, control outputs must be connecting to the heating and cooling devices. Please refer to the following for the operation of each setting.
RAMP/SOAK PROGRAMMING AND OPERATION The ramp/soak feature offers a great deal of flexibility by allowing changes in the set point to be made over a predetermined period of time. Theory of Operation The B series controls offer a very simple approach to programming a ramp function. Rather than requiring the operation to calculate an approach rate (usually in degrees per minutes), the B series does the calculation internally.
Program Setup All of the programming for the Ramp/Soak function is done in the Initial Setting Mode. You may wish to work out your program on paper before going into the programmer menu sequence. In the Initial Setting Mode, go to the Control Mode (CtrL) parameter. Set the parameter to ProG. Press INDEX to the Pattern Editing parameter (PAtn). Use the arrows to select the desired pattern to edit.
Execution The execution of the ramp and soak feature is initiated through the Run/Stop parameter, (rS) in the Operation Mode. The Run/Stop parameter has four possible values. If the Run/Stop parameter is set to rUn, the program will start to execute in order from step 0 of the start pattern. If the Run/Stop parameter is set to Program Stop (PStP), the program will stop and maintain the temperature of the last set point before the program was halted.
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.
DESCRIPTION OF MENU STRUCTURE The programming for the controller is broken down into three menus (Operation, Regulation, and Initial Setting). Upon normal operation, control will be in the Operation Menu. OPERATION MENU Pressing the INDEX key will cycle through the below menu items. The parameter will be displayed in the top display, while its value will be displayed in the bottom display, except for the set point which is displayed in the bottom display on the Home Display.
AL1L Alarm 1 Low Set Point. May not appear depending on ALA1 setting in Initial Setting Menu. AL2H Alarm 2 High Set Point. May not appear depending on ALA2 setting in Initial Setting Menu. AL2L Alarm 2 Low Set Point. May not appear depending on ALA2 setting in Initial Setting Menu. AL3H Alarm 3 High Set Point. May not appear depending on ALA3 setting in Initial Setting Menu. AL3L Alarm 3 Low Set Point. May not appear depending on ALA3 setting in Initial Setting Menu.
REGULATION MENU Press the ENTER key while at the Home Display in order to access the Regulation Menu. Pressing the INDEX key will cycle through the below menu items. The parameter will be displayed in the top display, while its value will be displayed in the bottom display. The UP and DOWN arrows change the values of the parameters. The ENTER key must be pressed after any changes. Auto Tune. The controller will evaluate the process and select the PID values to maintain good control.
PdoF PD Offset Correction Setting. only available when control mode is set to PID and integral time = 0. See Programming and Operation of PID function for moving information. HtS Heating Hysteresis (Differential) Setting. Sets the value for the amount of difference between the turn off point (set point) and the turn on point. Figure A shows the output behavior for a heating (reverse acting) application. Only available when control mode set to on/off control.
CoEF dEAd Proportional Band Coefficient. Sets the value of the proportional band for output 2. The proportional band of output 2 is equal to the proportional band of output 1 multiplied by the proportional band coefficient. This parameter is only available when the control mode is set to PID and Dual Loop Output Control. Dead Band. The zone centered on the set point in which the control is thought to be at the desired set level.
INITIAL SETTING MENU Press and hold the ENTER key for at least 3 seconds while at the Home Display in order to access the Initial Setting Menu. Pressing the INDEX key will cycle through the below menu items. The parameter will be displayed in the top display, while its value will be displayed in the bottom display. The UP and DOWN arrows change the values of the parameters. The ENTER key must be pressed after any changes. inPt Input Selection. Select one of the following input types from the below table.
Control Mode. Select method of control operation. Can be set to PID, On-Off, Manual, or Ramp/Soak Programming. CtrL PAtn Ramp/Soak Pattern Selection. Allows user to select which of the 8 ramp/soak patterns to program. Each pattern has 8 steps which gives a total of 64 possible steps in a single program. When finished programming all ramp and soak patterns, the parameter should be set to off. (n = 0 to 7) SPnY tinY Segment Time for pattern n and step y.
SALA System Alarm Setting. Selects which of the alarm outputs is used if a system alarm occurs. The system alarms would be an input error or a process control failure. This feature can be disabled by turning this parameter to oFF. CoSH Communications Write Function Feature. Allows parameters to be changed via the RS-485 communications. Setting to oFF prevents any changes from remote users. C-SL Protocol Selection: Select whether to communicate using ASCII or RTU Protocol.
