INTRODUCTION . . The CAL 9000 temperature controller is based on proven temperature control techniques, but it incorporates substantial improvements due to the use of modern digital technology involving a microprocessor . Good functional design ensures that the versatile features of the 9000 have made it simple to use . For the majority of applications it is only necessary to key in the sensor type . It will then automatically operate with Default (factory) settings for the PID Control terms making it suitable for a wide range of applications which
require a single setpoint, slow cycle, proportional output controller .
To use the 9000 with Default settings see Sections Bt - BS. For more complex or difficult applications the Default settings can be overridden by more appropriate values, alternative control modes or enabling of the second set point . When the appropriate parameters are keyed in, they can be 'locked' to prevent unauthorised adjustment . Sec Section B6-8 9

For ease of use in normal applications, the CAL 9000 has been preset with factory or DEFAULT settings in place of customers OPTIONS . These preset parameters enable the instrument to operate in PID Control mode with single setpoint . slow cycle, prooortional output . This configuration should give good results where the heater is adequatel y
rated and the control sensor is sited reasonably close to it . Default settings (for SP1 only) are : Prooortiona, Time .' 30 secs Cycle rate Proportional Band/ =2,5% of Default Gain full scale Derivative Time/Rate =25 secs Integral Time/Auto Reset =350 sec s
Default Range Table be keyed into the instrument . The Default Range will limit the setpo nt values only. The instrument will indicate process temperatures over the full linearised range shown in the table in Section 89 . It is important to ensure that the range maximum is compatible with safety. Proceed as follows : Apply power . All LED segments will be briefly illuminated during the self check routine, then the display will request sensor selection, ie . The Option number for Function 16, and will not respond to any further instructions until this is made.
To use the controller with Default settings requires only that the Option number of the sensor, selected from the Sensor

SECTION C I Tunin g If the preset PID DEFAULT values prove to be unsuitable for a particular application, the following method can be used to establish new settings which should be acceptable and which can be adjusted to give optimum control . This method of tuning may differ from that used on other controllers. The first step is to control the system with the instrument in ON/OFF mode and use these results to calculate the new Parameter values for SP1 . Check that all settings are in DEFAULT . If required, range adjustments should be made first . Refer to Section 36. Check that Parameter Lock is in the Parameter Setting position (Section 811) and proceed as follows : i . Adjust Proportioning Time to ON/OFF (This switches off all other control terms and sets Hystersis to 1 .25% of full scale) . ii . Key in Set-point temperature. iii . Switch on and allow the process to stabilise . Then monitor process temperature, ideally using t . chart recorder, or alternatively by taking readings from the display at regular interv ls, as frequently as possible . The results should look similar to the example .
iv . Using the figires obtained for the oscillation period (T) seconds and amplitude (A) degrees, the following Parameter values can be calculated . a. Proportonal Time/Cycle Rate = T If 10 seconds or less use SSR . 20 b . Proportional Bend %/ = A x 1,5 x 100 Set to next LARGER % setting. Gain % full scale c . Derivative Time/ Rate = T Set to next SHORTER time setting . 10 d . Integral Time/Auto Reset = T Set to next LONGER time setting . ' (Approach control will be activated in DEFAULT setting = 1 .5 x prop band . If the warm up characteristic is unacceptable, refer to Section C6) . v. Enter these new values and restart the process from cold .
The above settings can be further adjusted to give optimum performance . The following curves and notes will provide guidance for tuning the individual contro l
terms. _

Ideal Setting Setting Too Lon g This term is employed to smooth out the Oscillating control characteristic typical of ON/OFF control . A feature: of proportional control is that the system may run at a slightly different temperature to the set-point (Offset), and have a slower reaction to disturbances .

The purpose of the integral term is to automatically correct for offset errors Caused by the introduction Of PROPORTIONAL control . If incorrectly set this can cause instability or increase warm up time .
Setting too short Ideal setting Setting too lon g

The derivative term is added to PROPORTIONAL control action to speed up response to disturbances aid to suppress overshoot . In applications where these two requirements would need different settings, the use of Derivative Approach Control for adjusting warm up characteristics allows the Derivative setting to be biased in favour of disturbance behaviour.

Setting too long Ideal setting Setting too short
This feature allows the warm up characteristics to be tuned separately from normal running conditions and is particularly useful for applications where the sensor is some distance from the heater . The setting determines where the derivative action starts with respect to set-aoint . The smaller the setting, the closer to set-point .
Setting too small Setting ideal Setting too large Where a given application cannot be tuned to give acceptable results over the required range of process temperatures and conditions, it is possible that better results may be obtained with Proportional, Derivative and Approach Control terms only . 'Cann . Ideal settings for these systems are very dependant on the application, and are often best determined by experiment.
The following general points may prove useful for initial consideration . A common characteristic is that there is a considerable difference between the syste m
response to the input of heating and of cooling energy .
In general, bosh channels can be set independantly using the Tuning guidelines for settings for Proportional Time and Proportional Band, and where it is known that one channel has a dominating and rapid effect on system temperature, the employment of narrow hysteresis ON/OFF settings for this may give excellent results . Where both sirtpoints are required to be set close together (small deadband), wide proportional or hysteresis band settings will overlap allowing simultaneous operation of outputs, which may give the best overall control .
