SECTION 1: PRODUCT DESCRIPTION 1.1 General This instrument is a microprocessor based single loop controller capable of measuring, displaying and controlling temperature, pressure, flow, and level from a variety of inputs. Most outputs are easily tuned using the instrument Pre-Tune and Auto-Tune, or RaPID (Response assisted PID) functions. Control functions, alarm settings and other parameters are easily entered through the front keypad.
1.2 Displays Each instrument is provided with dual displays and status indicators as shown in Figure 1 -1. The upper display (RED) displays the value of the process variable. The lower display (GREEN) displays the setpoint value. 1.3 Control The instrument can be programmed for on-off, time proportioning, or current proportioning control implementations depending on the model number. A second control output is an available option.

2.2 Wiring Guidelines Electrical noise is a phenomenon typical of industrial environments. The following are guidelines that must be followed to minimize the effect of noise upon any instrumentation. Installation Considerations Listed below are some of the common sources of electrical noise in the industrial environment: • • • • Ignition Transformers Arc Welders Mechanical contact relay(s) Solenoids Before using any instrument near the device listed, the instructions below should be followed: 1.
AC Power Wiring Neutral (For 115 VAC) It is good practice to assure that the AC neutral is at or near ground potential. To verify this, a voltmeter check between neutral and ground should be done. On the AC range, the reading should not be more than 50 millivolts. If it is greater than this amount, the secondary of this AC transformer supplying the instrument should be checked by an electrician. A proper neutral will help ensure maximum performance from the instrument.
Noise Suppression At The Source Usually when good wiring practices are followed no further noise protection is necessary. Sometimes in severe electrical environments, the amount of noise is so great that it has to be suppressed at the source. Many manufacturers of relays, contactors, etc. supply "surge suppressors" which mount on the noise source. For those devices that do not have surge suppressors supplied, RC (resistancecapacitance) networks and/or MOV (metal oxide varistors) may be added.
FIGURE 2-5 2.3 Sensor Placement (Thermocouple or RTD) Two-wire RTDs should be used only with lead lengths less than 10 feet. If the temperature probe is to be subjected to corrosive or abrasive conditions, it should be protected by the appropriate thermowell.
FIGURE 2-6 Wiring Label 1/4 DIN 11
2.4 Input Connections In general, all wiring connections are made to the instrument after it is installed. Avoid Electrical Shock. AC power wiring must not be connected to the source distribution panel until all wiring connection procedures are completed. Caution: This equipment is designed for installation in an enclosure which provide adequate protection against electric shock. Local regulations regarding electrical installation should be rigidly observed.
FIGURE 2-7A 24V Nominal AC/DC Supply The supply connection for the 24V AC/DC option of the instrument are as shown below. Power should be connected via a two pole isolating switch and a 315 mA slow-blow (anti-surge type T) fuse. With the 24V AC/DC supply option fitted, these terminals will accept the following supply voltage ranges: 24V (nominal) AC 50/60 Hz 24V (nominal) DC - 20 - 50 V 22 - 65 V FIGURE 2-8 Thermocouple (T/C) Input Make thermocouple connections as illustrated below.

SECTION 3: OPERATION 3.1 Control Capability The capabilities available in a specific unit are dependent upon the hardware options specified when the instrument is ordered. Refer to Appendix E for the decoding of the instrument model number. Current proportioning control cannot be implemented if a current output was not ordered.
3.3 Direct/Reverse Operation of Outputs Direct operation is typically used with cooling applications. On-Off direct output(s) will turn on when the process variable exceeds setpoint. Proportional direct output(s) will increase the percentage of output as the process value increases within the proportional band. Reverse operation is typically used with heating applications. On-Off reverse output(s) will turn off when the process variable exceeds setpoint.
When the unit is operating in the Control Mode, the control algorithm determines the output % required to correct for any difference between the process value and the setpoint. The output calculation is affected by Tune Mode parameter adjustments. See Figure 3-1 for proportional bandwidth effect on the output. 3.6 Current Proportioning Control Current Proportioning control can be implemented on units provided with mADC current output(s).
FIGURE 3-1 Proportional Band 1 24
3.7 Power Up Procedure Verify all electrical connections have been properly made before applying power to the instrument. If the instrument is being powered for the first time, it may be desirable to disconnect the controller output connections. The instrument will be into control following the power up sequence and the output(s) may turn ON. During power up, a self-test procedure is initiated during which all LED segments in the two front panel displays appear and all LED indicators are ON.

* The Hardware Definition Code and input jumper configuration may need to be changed. See Appendices A and B. ** If Remote Setpoint Input has been selected in the Hardware Definition Code, this parameter will appear in the normal Program Mode parameter sequence. The upper display shows a product code which defines the input range. The factory setting depends on code selected, see Appendix B.
8.2 Hardware Definition Code The Hardware Definition Code is used to represent the hardware installed (input type, Output 1 type, Output 2 type and Output 3 type); this must be compatible with the hardware actually installed. It can be accessed, with the instrument in Configuration Mode (with a prompt inPS, etc. displayed), by simultaneously depressing the DOWN and SCROLL keys.
The displayed code may be incremented/decremented using the UP/ DOWN keys as required. The maximum setting available is 4777. For example, the code for a thermocouple input, DC 4-20 mA Output 1 and relay Output 3 would be 2701. When the code is first altered, the code display will flash, until the desired value is displayed and confirmed by pressing the Auto/Manual key.
NOTE: It is essential that this code is changed whenever there is a change to the instrument's hardware configuration (change of input/output type, alarm/ retransmit output added/removed etc.). The instrument's software depends upon this code to ensure that the instrument operates correctly. To exit from the Hardware Definition Code display, depress the DOWN and SCROLL keys simultaneously.
SECTION 9: CALIBRATION MODE 9.1 Entering Calibration Mode To enter the Calibration Mode from Setup Mode: 1. Press the SCROLL key until CAL appears in the message display 2. Press the DOWN key to enter the Calibration Mode. NOTE: Calibration should be attempted only on Controllers on which calibration errors have been encountered (see CALIBRATION CHECK). 9.2 Calibrating The Universal Input Equipment Required 1. Input source with an accuracy better than +/- 0.05 of reading: a.
3. Enter Calibration Mode (Section 9.1). The upper display will then show Input Type Number, in the form: iP_I and the lower display will show: CAL Using the UP/DOWN keys, change the input type number as required (see Table 9-1). NOTE: If required, only one input type may be calibrated. Exception: If it is required to calibrate the thermocouple input (Input Type 5), it is necessary first to calibrate the DC 0 - 50 mV input (Input Type 1). Table 9-1 Universal Input Type Selection Input Type No.
9.3 Calibrating The Secondary Analog Input Equipment Required 1. DC linear input source (0 - 5 V and 0 - 20 mA) with an accuracy better than +/0.05% of reading. 2. Case assembly, wired for appropriate input supply (90 - 264V AC 50/60 Hz, 20 50 VAC 50/60 HZ or 22-65 VDC). Calibration Procedure 1. Ensure that the Controller is powered off and that the line power lead is disconnected. On the CPU PCB, configure link jumpers LJ10 and LJ11 (see Figure A-2).
6. To calibrate all inputs, repeat Steps 1 to 4 for each of the other input types (see Table 9-2) until all three secondary analog input types have been successfully calibrated. Table 9-2 Secondary Analog Input Type Selection Input Type No.
SECTION 10: ENABLE MODE 10.1 Enable Mode Description The Enable Mode controls access to the various modes available. To access the Enable Mode from the Control Mode, press the SCROLL key until Mod is displayed. Press the DOWN key. This puts the control in Setup Mode. Press the SCROLL key until EnAb is displayed. Press and hold the DOWN key for five seconds. The lower display will read PASS. Use the UP and DOWN keys to change the upper display to the correct Pass Code. Press the SCROLL key.

SECTION 11: PRE-TUNE MODE 11.1 Pre-Tune Mode Description The Pre-Tune Mode may be used to set the instrument's PID parameters to values which are approximately correct, in order to provide a base from which the Auto Tune Mode may optimize tuning. To engage the Pre-Tune Mode, with the instrument in Control Mode, press the SCROLL key until Mod is displayed. Press the DOWN key. Press the SCROLL key until Pre is displayed. Press the UP key until the AT LED flashes.
58
SECTION 12: AUTOTUNE MODE 12.1 AutoTune Mode and Description The Auto-Tune Mode is used to optimize tuning while the instrument is operating. To access the Auto-Tune Mode, with the instrument in Control Mode, enter the Setup Mode. Press the SCROLL key until Auto is displayed. To engage Auto-Tune, press the UP key. The AT LED will light red.
New instruments supplied by the factory contain PID terms set at "DEFAULT" values which have been found to give adequate and safe control over a wide range of applications. In the "Pre-Tune" mode of operation, the "default" PID terms are loaded and the controller demands 100% power until the process value has moved approximately halfway to the setpoint. At that point, power is removed thereby introducing a deviation oscillation.
SECTION 13: RaPID FEATURE 13.1 RaPID Description The RaPID (Response assisted PID) range of controllers have been designed with a unique "fuzzy" logic algorithm which dramatically reduces overshoot and improves settling times on start-up, setpoint changes and disturbances by 70%, without complicating set-up and usage. The fuzzy logic based algorithm enhances the traditional PID function, continuously reblending the P, I and D control building blocks on line.

For DC Inputs Note: Input conditioning jumper LJ1, LJ2. or LJ3 needs to be changed, see Appendix A.
APPENDIX C: RaPID CONTROL FEATURE The RaPID (Response - assisted PID) feature offers dramatic improvements in control quality compared with conventional PID techniques. It responds much more effectively than PID techniques to load conditions. With this feature, the instrument's response at start-up, during setpoint changes and during disturbances shows considerably reduced overshoot and much more shorter settling times (see below). RaPID works best with well-tuned terms.
In conditions of frequent change in load characteristics, it is recommended that the Auto-Tune facility is used. Note: With Auto-Tune and RaPID engaged together, Auto-Tune is suspended until RaPID is disengaged, whereupon Auto-Tune will operate automatically.
