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 B 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 (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.
If the Ramp and Soak feature is active, then bottom display will show the current execution pattern and current execution step. The UP and DOWN arrows can be pressed to change the bottom display to show the Set Point (SP) of the current execution step or the Time Remaining (r-ti) of the current execution step. After changing the bottom display to either the Time Remaining or the Set Point, the ENTER key must be pressed to display the values.
Error Messages are shown on page 26.

OPTIONS

Event Input
When the controller is ordered with the Event Input Option (See page 3 for ordering information), two event inputs are available. The event input is triggered by contact closure between event 1 (EV1) or event (EV2) contact terminal and signal ground (SG) contact terminal.
Event 1 controls the output operation of the control. When the event 1 contact terminals are open, the output is active. When the event 1 contact terminals are closed, the output is deactivated.
The outputs can also be controlled via the Run/Stop parameter using the front keypad or by using the RS-485 communications.
Event 2 allows the user to switch between two temperature set points. Each temperature set point has independent control parameters.
Current Transformer Alarm Function
The current transformer option allows the user to have an alarm contact trigger due to a loss of current or a surge in current to the control output. When using the current transformer input, the desired alarm contact should be set to alarm type 13 in the Initial Setting Menu (Page 21). The current transformer should be wired according to the appropriate wiring diagram on page 6 and page 7. The high and low alarm set points can be set from 0.5 to 30 Amps. The display resolution is 0.1 Amps and the accuracy is ±0.5 Amps with the included current transformer.

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.
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. If selected, output 2 will become alarm 3.
Select CooL, for cooling or direct acting control for output 1. If selected, output 2 will become alarm 3.
Select H1C2 or C1H2 for Dual Loop Output Control for output 1 and 2. If H1C2 is selected, output 1 would be fore heating or reverse acting control and output 2 would be for cooling or direct acting control. If C1H2 is selected, output 1 would be for cooling or direct acting control and output 2 would be for heating or reverse acting control.
Setting the control mode to PID when the controller is set for Dual Loop Output Control Activates the Proportional Band Coefficient (CoEF) parameter and the Dead Band (dead) parameter.
The Proportional Band Coefficient (CoEF) sets the Proportional band value for Output 2 based on the Proportional band of output 1. The Proportional Band of Output 2 would be equal to the Proportional Band (Pn) of Output 1 multiplied by the Proportional Band Coefficient (CoEF). The Integral Time (in) and the Derivative Time (dn) will be the same for both Outputs.
The Dead Band (dEAd) parameter sets an area in which the heating and cooling outputs are operating at 0% on. The Dead Band is centered on the Set Point in Dual Loop Output Control mode. Please see the Dead Band illustrated on page 19.

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. Thus, the operator only needs to program the target set point and the time desired to reach that point. When the ramp segment is executed by the control, it calculates the ramp required to move the process from the starting value (current PV) to the desired value (programmed SP) in the time allowed.
Soaks (or dwells) are ramp segments where the target set point is the same as the beginning process value. This allows for multistage ramps without wasting intermediate soak steps.
Care must be taken, however, that the process does actually reach the soak value before the soak time starts. If not, the next segment will calculate a slope from the starting PV to the target SP. Depending on your process requirements, this difference may be important.
Make sure to test any program for desired results before running production material.
Do not operate auto-tuning while a ramp function is operating. The ramp function will prevent self tune from operating properly. Make sure that all tuning is set up before
operating ramp/soak.

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. By setting the Pattern Editing parameter to off, pressing the INDEX key brings up the next parameter in the Initial Setting mode. The Ramp and Soak function is supported by 8 different patterns (pattern numbers 0 to 7). Each pattern contains 8 steps (step numbers 0 to 7) for set point and execution times, one link pattern (Linn) parameter, one cycle parameter (CyCn), and one actual step parameter (PSYn).
The default of step 0 in pattern 0 is a soak function. The control should be programmed to reach the Set Point (SV) temperature, X, after the execution time, T. The unit will control the process temperature (PV) to reach temperature X and the keep the temperature at temperature X. The execution time T is determined by the execution time (ti00) for step number 0. The target set point (SP00) for step number 0 should equal the Set Point (SV) temperature.
After the first step, program SP01 and ti01 through SP07 and ti07 for the first pattern. The target set point value (SP0n) is in actual units just like your Set Point (SV). If the control is set for temperature, then the target set point displays are in temperature. If the control is programmed for some other engineering unit, the target set point displays will be set in that unit. The target execution time (ti0n) is in units of time, (hh.mm). The step parameters will be followed by the Actual Step parameter, Cycle parameter, and the Link parameter for each pattern.
The Actual Step parameter (PSYn) sets the last executable step for the current pattern. For example, if the Actual Step parameter is set to 2 for pattern 0, then the program will only run steps 0, 1, and 2 for pattern 0.
The Cycle parameter (CyCn) determines how many times the current pattern is repeated.
For example, if the Cycle parameter for pattern 0 is set to 2, the steps in pattern 0 will be repeated twice before moving on to the next pattern.
The Link parameter (Linn) assigns the next pattern for the program to execute. For example, if the Link parameter is set to 3 for pattern 0, the program will skip patterns 1 and 2 and start executing pattern 3 after pattern 0 is complete. If the Link parameter is set to oFF, the program will stop after executing the current pattern and the temperature will be maintained at the set point of the last step executed.

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. When the Run/Stop parameter is restarted, the program will restart and execute from step 0 of the start pattern.
The start pattern selection (Ptrn) is only available when the Run/Stop parameter is set to Program Stop.
If the Run/Stop parameter is set to Program Hold (PHod), the program will be paused and the temperature will be maintained at the set point temperature that was active prior to the program hold. Once the Run/Stop parameter is set back to run, the program will follow the step before the hold and start to execute through the rest of the program.
Display
During ramp and soak program control, the SV default display is P-XX, where P indicates the current execution pattern and XX indicates the display item to Set Point Value (SP) or Residual Time (r-ti). The Set Point Value will display the temperature set point of the current execution step in the SV display. The Residual Time will display the remaining time of the current execution step in the SV display. After selecting the Set Point Value or Residual Time, the ENTER key must be pressed to accept the display change.

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 (PdofF) would replace the integral deviation offset correction, but serves the same function.
Program Set Up
In order to use the PID function in the B 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.
The B series controller has four user-defined profiles (PID0 to PID3) of PID values along with an auto selection function (PID4). Each set of PID values includes a set point value (Svn), proportional band (Pn), integral time (in), derivative time (dn), and integral deviation setting (iofn). If PID4 is selected, the controller will pick which set of user defined parameters to use based on how close the set point value of the profile is to the current process value.
