Operation 3.2 Behaviour after power-on After supply voltage switch-on, the unit starts with the operating level. The unit is in the condition which was active before power-off. If the 8800 process controller was in manual mode at supply voltage switch-off, the controller will re-start with the last output value in manual mode at power-on. 3.3 Operating level The content of the extended operating level is determined by means of 8800/8840 configurator (engineering tool).
Operation 3.4 Error list / Mainenance manager With one or several errors, the extended operating level always starts with the error list. Signalling an actual entry in the error list (alarm, error) is done by the Err LED in the display. To reach the error list press Ù twice.

Operation g g Saved alarms (Err-LED is lit) can be acknowledged and deleted with the digital input di1/2/3, the è-key or the Ò-key. Configuration, see page 37: ConF / LOGI / Err.r If an alarm is still valid that means the cause of the alarm is not removed so far (Err-LED blinks), then other saved alarms can not be acknowledged and deleted. Self-tuning heating ( ADA.H) and cooling ( ADA.
Operation 3.5 Self-tuning For determination of optimum process parameters, self-tuning is possible. After starting by the operator, the controller makes an adaptation attempt, whereby the process characteristics are used to calculate the parameters for fast line-out to the set-point without overshoot. The following parameters are optimized when self-tuning: Parameter set 1: Pb1 - Proportional band 1 (heating) in engineering units [e.g.
Operation 3.5.2 Optimization after start-up or at the set-point The two methods are optimization after start-up and at the set-point. As control parameters are always optimal only for a limited process range, various methods can be selected dependent of requirements. If the process behaviour is very different after start-up and directly at the set-point, parameter sets 1 and 2 can be optimized using different methods. Switch-over between parameter sets dependent of process status is possible (see page 25).
Operation The controller attempts to calculate the optimum control parameters from the process response. If this is done successfully, the optimized parameters are taken over and used for line-out to the set-point. With a 3-point controller, this is followed by “cooling”. After completing the 1st step as described, a correcting variable of -100% (100% cooling energy) is output from the set-point.
Operation Optimization-at-the-set-point procedure: The controller uses its instantaneous parameters for control to the set-point. In lined out condition, the controller makes a pulse attempt. This pulse reduces the correcting variable by max. 20% 1, to generate a slight process value undershoot. The changing process is analyzed and the parameters thus calculated are recorded in the controller. The optimized parameters are used for line-out to the set-point.
Operation Optimization at the set-point for 3-point stepping controller With 3-point stepping controllers, the pulse attempt can be made with or without position feedback. Unless feedback is provided, the controller calculates the motor actuator position internally by varying an integrator with the adjusted actuator travel time. For this reason, precise entry of the actuator travel time (tt), as time between stops is highly important.
Operation 3.5.4 Self-tuning start Start condition: w For process evaluation, a stable condition is required. Therefore, the controller waits until the process has reached a stable condition after self-tuning start. The rest condition is considered being reached, when the process value oscillation is smaller than ± 0,5% of (rnG.H - rnG.L). w For self-tuning start after start-up, a 10% difference from (SP.LO ... SP.Hi) is required.
Operation 1. Press keys Ù and È simultaneously: The controller continues controlling using the old parameters in automatic mode. The Err LED continues blinking, until the self-tuning error was acknowledged in the error list. 2. Press key Ò (if configured): The controller goes to manual mode. The Err LED continues blinking, until the self-tuning error was acknowleged in the error list. 3. Press key Ù : Display of error list at extended operating level.
Operation 3.5.7 Examples for self-tuning attempts (controller inverse, heating or heating/cooling) X Start: heating power switched on W 2 Heating power Y is switched off (1). When the change of process value X was constant during one minute (2), 100% Y the power is switched on (3). 0% 1 t reversal point Start r 3 At the reversal point, the self-tuning attempt is finished and the new parameter are used for controlling to set-point W. X Start: heating power switched off W The controller waits 1,5 minutes (1).
Operation 3.6 Manual self-tuning The optimization aid can be used with units on which the control parameters shall be set without self-tuning. For this, the response of process variable x after a step change of correcting variable y can be used. Frequently, plotting the complete response curve (0 to 100%) is not possible, because the process must be kept within defined limits.

Operation 3.8 Alarm handling Max. three alarms can be configured and assigned to the individual outputs. Generally, outputs OuT.1... OuT.6 can be used each for alarm signalling. If more than one signal is linked to one output the signals are OR linked. Each of the 3 limit values Lim.1 … Lim.3 has 2 trigger points H.x (Max) and L.x (Min), which can be switched off individually (parameter = “OFF”). Switching difference HYS.x and delay dEl.x of each limit value is adjustable.
Operation g The variable to be monitored can be selected seperately for each alarm via configuration The following variables can be monitored: w process value w control deviation xw (process value - set-point) w control deviation xw + suppression after start-up or set-point change After switching on or set-point changing, the alarm output is suppressed, until the process value is within the limits for the first time. At the latest after expiration of time 10 ti1, the alarm is activated.

Configuration level 4.4 Switching behaviuor With 8800 process controller, configuration parameter CYCL (ConF/ Cntr/ CYCL) can be used for matching the cycle time of 2-point and 3-point controllers. This can be done using the following 4 methods. 4.4.1 Standard ( CyCl= 0 ) The adjusted cycle times t1 and t2 are valid for 50% or -50% correcting variable. With very small or very high values, the effective cycle time is extended to prevent unreasonably short on and off pulses.
Configuration level Parameters to be adjusted: ( PArA / Cntr) E.H2O: minimum temperature for water cooling t.on: pulse duration water cooling t.off: minimum pause water cooling 4.4.3 Switching attitude non-linear ( CyCl= 2 ) 70 -95% -67% -80% -100% -92% Parameter: t.on = 0.4 sec t.off = 0.2 sec 60 Effective controller output -90% -87% -82% With this method, the cooling power t.on t.off is normally much higher than the heating power, i.e.
Configuration level 4.4.4 Heating and cooling with constant period ( CyCl= 3 ) 1 and t2 are met in the overall tp output range . To prevent t1/ t2 unreasonably short pulses, parameter tp is used for adjusting the shortest pulse duration. With small correcting 30% 20% 50% values which require a pulse shorter than the value adjusted in tp, this tp pulse is suppressed. However, the t1/ t2 controller stores the pulse and totalizes further pulses, until a pulse of duration tp can be output.

Special functions 7 Special functions 7.1 DAC®– motor actuator monitoring (Digital Actor Control DAC®) With all controllers with position feedback Yp, the motor actuator can be monitored for functional troubles. The DAC® function can be started by chosing the parameter C.Fnc = 5 or 6 at the configuration level ( ConF): w ConF / Cntr / C.Fnc = 5 3-point-stepping controller with position feedback Yp as potentiometer w ConF / Cntr / C.
Special functions Functioning of the DAC function No input filter should be defined for the Yp input ( PArA / InP.x / t.Fx = 0 ). Therewith no wrong detection of blocking or wrong method of operation can be recognized. The automatic calibration can be used with drives outfitted with spring assembly. Execution of the calibration: It is controlled if the mean alteration between two messurements is enough for the DAC monitoring.
Special functions 7.2 O2 measurement This function is available only on the instrument version with INP3. As the O2-measurement result range can extend over many decades, automatic display switch-over between “ % ” and “ppm“ was realized. The instantaneous unit is displayed in the lower line. With set-point changing via keys I or D, the unit of the set-point and of the other parameters is displayed. Lambda probes (λ probes) are used as sensors.
