Product Description 1.1 1.1.1 GENERAL The instrument is a microprocessor based circular chart Recording Profile Controller capable of measuring, displaying, recording and controlling a variety of inputs. Applications include temperature, level, pressure, flow and others. The instruments can be specified as either a single or as a dual pen model. The second pen can be selected as a profile control or a single setpoint control.
1.1.2 RECORDING The instrument records the selected process variable on a 10-inch circular chart. One box of standard charts is provided with each recorder. Charts are available in a wide selection of ranges. Chart rotation speed is programmable from 0.1 to 999.9 hours per revolution in 0.1 hour increments. The instrument can be ordered with one or two pens. Pen 1 is red and Pen 2 is green. Pens are the disposable fiber-tip type. 1.1.
1.1.7 DIGITAL COMMUNICATIONS The instrument can be ordered with a Digital Communications option that provides the capability of bi-directional communications with a supervisory computer. A dual pen instrument can have an individual address selected for each pen. Refer to the Communications Protocol Manual (Form 2878) for more details regarding the communications option. This manual is included with the unit when the communications option is specified.

2.5.2 SENSOR PLACEMENT (THERMOCOUPLE OR RTD) Thermocouple lead resistance should not exceed 300 ohms. If this is exceeded, instrument accuracy could be affected. Two wire RTD's should only be used 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. The probe should be positioned to reflect true process temperature: In liquid media - the mose agitated area.
RTD LEAD RESISTANCE RTD lead length can affect instrument accuracy. Size (gauge) and length of the wire used affects lead length resistance. To determine the temperature error resulting from the lead length resistance, use the following equation: Terr = TLe * L where; TABLE 3 3 Wire RTD AWG No. 10 12 14 16 18 20 24 TABLE 4 AWG No. 10 12 14 16 18 20 24 TLe = value from Table 3 if 3 wire or Table 4 is 2 wire. L = length of leadwire in thousands of feet. Error °C +/-0.04 +/-0.07 +/-0.10 +/-0.16 +/-0.

Direct action is typically used in cooling applications.
Proportional Output 1 Action P1EC on error condition does not apply to position proportioning control. In an error condition, the unit goes only to 0% output (fully closed). With Position Proportioning control, it may be necessary to adjust the Sensitivity Tune SEnS mode parameter to reduce or eliminate oscillations of the motor around setpoint. If oscillation occurs, increase the SEnS value until the motor stops oscillating.
To return to the Control mode of operation from the Manual mode, press the specified AUTO/ Man key. If the Automatic Transfer feature is selected in the Program mode, the instrument will switch from Manual mode to the Control mode when process value reaches the setpoint value. Alarm Operation 4.2 There are two alarms available per pen. The type of alarm is selected in the Program mode as follows: 1. Process Alarm Direct - the alarm will be On if the process value is greater than the process value selected.
Tune Mode Operation 4.3 Proportional output controllers may require the adjustment (tuning) of the PID and other related parameters. This provides a means for the instrument's control algorithm to be adjusted to meet specific application requirements. 4.3.1 SYSTEMATIC TUNING METHOD 1. Changes in tuning parameters should be made one at a time. 2. After making any changes in tuning parameters, a disturbance should be introduced into the process so that the process reaction may be observed.
To aid in determining the process oscillation, the instrument configuration parameters can be adjusted. By reducing the chart upper value Cru and increasing the chart lower value CrL, the resolution of the oscillation can e better observed. Also the chart rotation time Crt can be reduced to improve the observation of the oscillation cycle time. Determining Ultimate Proportional Band and Ultimate Time Period 1. Set Manual Reset rSet to 0.0, set ArSt to 0.0 and set rAtE to 0.0. 2.

Appendix B Glossary Assured Soak The instrument may be programmed to interrupt the Profile Soak segment if the process value exceeds a selectable deviation from setpoint value. The Profile will restart from where it was stopped when the process value does not exceed the deviation value selected from setpoint. Automatic Reset (Integral) This parameter is used so that the instrument will compensate for process variable deviations from setpoint that occur when the process load characteristics change.
Input Correction This parameter is adjustable from -300 to 300 units and is used as a method to compensate for a linear sensor error. Factory default is 0=no correction. Display code iCi1 and iCi2. Manual Reset This parameter is adjustable from -1500 to 1500 units representing a manual shift of proportional band(s) relative to the normal position which is an even strattle of the setpoint.
Rate (Derivative) This parameter is adjustable from 0.0 to 10.0 minutes and specifies how the control action responds to the rate of change in the process variable. For example, if the process variable is rising rapidly to setpoint, power is turned off sooner than it would be if the rise were slow. In effect, derivative action anticipates lags within the system and shifts the proportioning band by an amount determined by the rate of change of the input sensor.
