2200 Temperature Controller User’s Guide When “SET” is pressed the display will show the set-point memory that is cur- rently being used and its value. Eight set-point memories are available. Access set-point selection Set-point 1, 25.°C currently used Press “SET” to select this memory and access the set-point value.
Setup Installation Setup The 2200 controller is a precision instrument which should be located in an ap- propriate environment. The location should be free from excessive dirt, mois- ture, vibration, or temperature variations. There should be no present danger of spilled liquids.
2200 Temperature Controller User’s Guide located in close proximity to the heater. Observe the maximum temperature rat- ing of the probe and be careful it is not exceeded. Rear Panel Probe Connector RTD Sensor Figure 2 RTD Probe Wiring Set the high limit (HL) less than or equal to the probe maximum temperature.
4 Installation Fuses Fuses CAUTION: Never use this instrument in a system that uses more power or current as listed in Section 2.1, Specifications on page 9. The controller is shipped from the factory with fast acting fuses rated for the maximum capacity of the instrument.
5 Parts and Controls Front Panel Parts and Controls Front Panel The following controls and indicators are present: (1) the digital display, (2) the control buttons. (see Figure 3) (1) The digital display of the temperature controller displays the set and actual temperatures and various controller functions, settings, and constants.
2200 Temperature Controller User’s Guide EXIT – Used to exit from a menu. When EXIT is pressed any changes made to the displayed value will be ignored. Back Panel The following features are found on the rear panel of the controller: (1) the power entry module, (2) the heater power connector, (3) the control probe input connector, and (4) the RS-232 interface connector (see Figure 4).

5 Parts and Controls Back Panel (C) The power entry module is provided with a dual voltage selector inte- grated into the fuse holder. The controller has been specially designed to allow either 115 or 230 VAC operation. The voltage indicator window no- tifies the user of the voltage selected.
General Operation Control System The 2200 temperature controller is not specified for use with a particular sys- tem. Its flexibility enable it to be used with a large variety of control systems. Often the controller is used with a precision constant temperature bath.
7 Controller Operation Process temperature Controller Operation This chapter discusses in detail how to operate the temperature controller using the front control panel. Using the front panel key switches and LED display the user may monitor the process temperature, set the temperature set-point in de- grees C or F, monitor the heater output power, adjust the controller proportional band, and program the probe calibration parameters, operating parameters, and serial interface parameters.
7 Controller Operation Temperature Scale Units Set-point memory 1, 25.°C currently used To change the set-point memory press “UP” or “DOWN”. Increment memory New set-point memory 4, 40.°C Press “SET” to accept the new selection and access the set-point value. Accept selected set-point memory 7.2.2 Set-point Value...

Change units New units selected Un= F Press “SET” to accept the new selection and access the scan.
7 Controller Operation Set-point Resistance 7.4.2 Scan Rate The next function in the main menu is the scan rate. The scan rate can be set from .1 to 99.9°C/min. The maximum scan rate however is actually limited by the natural heating or cooling rate of the instrument. This is often less than 100°C/min, especially when cooling.
2200 Temperature Controller User’s Guide 100.0 P Heater power To exit out of the secondary menu press “EXIT”. To continue on to the propor- tional band setting function press “SET”. Return to temperature display Proportional Band In a proportional controller such as this the heater output power is proportional to the process temperature over a limited range of temperatures around the set-point.
7 Controller Operation Controller Configuration The proportional band width is easily adjusted from the controller front panel. The width may be set to discrete values in degrees C or F depending on the se- lected units. The optimum proportional band width setting may be determined by monitoring the stability with a high resolution thermometer or with the con- troller percent output power display.
2200 Temperature Controller User’s Guide 7.10 Calibration Parameters CAUTION: Care should be exercised when adjusting these parameters as they affect the accuracy of the set-point. This procedure is explained in de- tail in Section 9. The calibration parameter menu is indicated by, Calibration parameters menu Press “SET”...
7 Controller Operation Operating Parameters 7.10.5 Integral time adjustment The integral time should be adjusted for the quickest settling time without caus- ing instability. As a general rule, the optimum integral time is about 80% of the period of the natural oscillation of the system. 7.11 Operating Parameters The operator of the controller has access to setup constants.

8 Digital Communication Interface Serial Communications Digital Communication Interface The 2200 controller is capable of communicating with and being controlled by other equipment through the digital interface. The RS-232 serial interface is standard. Hart recommends the use of shielded RS-232 cables for all remote communication.
2200 Temperature Controller User’s Guide Press “UP” repeatedly until the serial interface menu is indicated with “SE- rIAL”. Finally press “SET” to enter the serial interface parameters menu. In the serial interface parameters menu are the BAUD rate, sample rate, duplex mode, and linefeed parameters.
8 Digital Communication Interface Interface Commands ASCII character strings terminated with a carriage-return character (CR, ASCII 13). Interface Commands The various commands for accessing the controller functions via the digital in- terface are listed in this section (see Table 2). All commands are terminated with a carriage-return character.

9 Calibration Procedure Single Point Calibration Calibration Procedure Single Point Calibration For a quick calibration to a single point, R may be adjusted by itself without any calculations. If the system is reading high, adjust R in the calibration menu higher by small increments until the temperature of the system is correct. NOTE: This method may cause other temperature settings to be off by a degree or two.

9 Calibration Procedure Three Point Calibration Procedure 9.2.3 Accuracy & Repeatability 1. Check the accuracy of the calibrator at various points over the calibrated range. 2. If calibrator does not pass specification at all set-points, repeat the Calibra- tion Procedure.
Factory Reset Sequence. Hold the SET and EXIT buttons down at the same time while powering on the instrument. After the instrument displays -init-, release the buttons. The display shows -init-, then displays 2200, and then displays the firmware version. After performing the master reset sequence, all of the configuration parameters are reset to their default values.
