    GETTING STARTED Install the control as described on page 5. Wire your control following the instructions on pages 5-11. If you are using a two- wire transmitter as an input, see the drawing and instructions on page 7. Option wiring instructions are on pages 8-11. Option descriptions and specific instructions start on page 19.

  • Page 5: Installation

    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. If more than one instrument is required, maintain the minimum of spacing requirements as shown on the drawing below.

  • Page 6: Input Wiring

    For supply connections use No. 16 AWG or larger wires rated for at least 75°C. Use copper 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 and 15 VDC is rated CLASS 2.

  • Page 14: Notation Conventions For The Menus

    NOTATION CONVENTIONS FOR THE MENUS Because of the number of features available in this control, information is included that may not apply to your specific control. All usable features are included in this book, but may not be used in your process. To increase clarity the following conventions are used: 1.

  • Page 15: The Home Display

    Theory of Operation The 2600 Series controls offer a very simple approach to programming a ramp. Rather than requiring the operator to calculate an approach rate (usually in degrees per minute), the 2600 does the calculation internally. Thus, the operator only needs to program the target set point and the time desired to reach that point.
  • Page 16 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.
  • Page 17 The last menu item for the ramp / soak function is P E n d . P E n d determines what the control does when the program has ended. You may choose to have the program repeat (L o o P ), H o l d the last set point (1 6 S P ), revert to the local S P 1 , or turn the outputs off (O o F F ).

  • Page 18: Auto / Manual Operation

    Self Tune allows automatic selection of the necessary parameters to achieve best control operation from your 2600 Series control. If you are using the control output as a simple on-off function (O u t 1 set for O n O F ), none of the following will apply.

  • Page 19: Operation And Programming Of Options

    Program Setup and Operation Do not cool the process or add heat while the tuning is occurring. In the secondary menu set t u n E to S E L F . Skip L E r n and check to make sure that d F A C is set to the desired value. Back up to L E r n and set to Y E S .

  • Page 20: Option 934, 936, Isolated Analog Retransmission

    Option 934, 936, Isolated Analog Retransmission. The analog retransmission option allows the Process Variable or the Set Variable to be sent as an analog signal to an external device. The signal may be either 0 to 10 VDC (Option 936) or 0 (or 4) to 20 mADC (Option 934). The output may be changed in the field from one to the other by the toggle switch located on the top printed circuit board.

  • Page 21: Option 948, 4-Stage Set Point

    Option 948, 4-Stage Set Point. The 4-stage set point option allows four different values to be used for S P 1 and all of the values associated with the t u n E menu items. The control will switch to a given stage when an external contact or contacts are made or opened across the appropriate terminals at the rear of the control (S P S A , Set Point Switch Action, set for remote, r E ), or when the stage is selected from the Secondary Menu, S P (when S P S A is set for I n t ).

  • Page 22: Serial Communications Options And Nonvolatile Memory

    This is the type of memory that Love Controls uses to save the settings you program in your control. The reliability and longevity of the data retention is what allows us to guarantee a 10 year data retention without power.

  • Page 23: Menu Selections

    Adding one of the computer communications options (e.g. 992, 993, 995, 996) changes the picture. The speed of computer communications is such that hundreds of instructions can be made in less than a minute. In such a situation, the million erase / write cycles could be used up in a couple of months causing the chip (and the control) to fail.

  • Page 24: Secondary Menu

    SECONDARY MENU Hold UP ARROW & ENTER. Press INDEX to advance to the next menu item. Press UP ARROW or DOWN ARROW to change the value in the display. Press ENTER to retain the value. If your instrument is not equipped with alarms (third character of part number is ‘0’), the Secondary Menu starts with O u t 1 , below.
  • Page 25 # # t P Time Proportioning Cycle Time. Select 1 t P to 8 0 t P . A setting of 1 t P is recommended for solid state outputs (SSR or 1 t P 15 VDC). 2 t P to 8 0 t P Time Proportioning Control is adjustable in 1 second steps.
  • Page 26 # P u L Pulsed Time Proportioning Output: Select 1 P u L to 7 P u L . 1 P u L = Linear and 7 P u L = most nonlinear. Changes output linearity for use in cooling applications or for extremely fast response processes.
  • Page 27 Damping factor, Select O F F , 1 to 7. Sets the ratio of Rate to d F A C Reset for the S E L F t u n E mode. 7 = most Rate. Factory set to 3. For a fast response process the value should be lowered (less Rate).
  • Page 28 Approach Rate Time: Select O F F , 0 . 0 1 to 9 9 . 9 9 minutes. The function defines A r t E the amount of Rate applied when the input is outside of the Proportional Band. The A r t E time and the r t E time are independent and have no effect on each other.
  • Page 29 Ramp/Soak: Select O n or O F F P r o 9 Allows Programmed Ramp/Soak function to be started by the Run/Hold key on the control front panel. Turns Ramp/Soak function O F F and resets program to beginning. O F F Programmer function set: Select O n or O F F .
  • Page 30 Input Correction: Select - 5 0 0 to 0 to 5 0 0 °F, °C, or counts. This feature allows I n P C the input value to be changed to agree with an external reference or to compensate for sensor error. Note: I n P C is reset to zero when the input type is changed, or when decimal position is changed.
