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 8840 profiler 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 / Maintenance 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.

Operation ti2 td2 t2 - Integral time 2 (cooling) in [s] r only, unless set to OFF - Derivative time 2 (cooling) in [s] r only, unless set to OFF - Minimum cycle time 2 (cooling) in [s] r only, unless Adt0 was set to “no self-tuning” during configuration by means of 8800/8840 Configurator . Parameter set 2: analogous to parameter set 1 (see page 25) 3.5.1 Preparation for self-tuning w Adjust the controller measuring range as control range limits. Set values rnG.L and rnG.
Operation Optimization at the set-point: (see page 18) For optimizing at the set-point, the controller outputs a disturbance variable to the process. This is done by changing the output variable shortly. The process value changed by this pulse is evaluated. The detected process parameters are converted into control parameters and saved in the controller. This procedure optimizes the control loop directly at the set-point. The advantage is in the small control deviation during optimization. 3.5.
Operation Pulse attempt after start-up Condition: - tunE = 1 and sufficient set-point reserve provided. The controller outputs 0% correcting variable or Y.Lo and waits, until the process is at rest (see start conditions page 15) Subsequently, a short pulse of 100% is output (Y=100%) and reset. The controller attempts to determine the optimum control parameters from the process response. If this is completed successfully, these optimized parameters are taken over and used for line-out to 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 3.5.5 Self-tuning cancellation By the operator: Self-tuning can always be cancelled by the operator. For this, press Ù and È key simultaneously.With controller switch-over to manual mode after self-tuning start, self-tuning is cancelled. When self-tuning is cancelled, the controller will continue operating using the old parameter values. By the controller: If the Err LED starts blinking whilst self-tuning is running, successful self-tuning is prevented due to the control conditions.
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% At the reversal point, the self-tuning 1 t reversal point Start r 3 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 should 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 4.5 8840 profiler cooling functions With the 8840 profiler , 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. 4.5.1 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.
