10. Regulation with PID controller

Basic information:The AERtronic AS 300 is equipped with a software PID controller. It is used to control the suction pressure or discharge pressure. The actual value is read in at the analog input for the system pressure. The set value for the pressure can either be predefined over the operation panel or the communication Modbus/Profibus. A corresponding analog output (for example pressure control) then predefines the rotational speed for a frequency converter. An external speed pre-set is also possible with an analog input (ext. predefinition) or over the communication Modbus/Profibus, if available and configured.

Opening the control parameters

Set value for the PID controller. The control output attempts to keep the system pressure at this value.

If the system pressure exceeds this value, the machine is switched into idling mode if there is a load/idle control. If the pressure falls below the set pressure, the system switches back into operation under load. (Refer also to Run/Shutdown mode)

Controller in manual mode

If the PID controller is set to manual mode in the controller parameters, the selected value can be changed by using the shown cursor buttons.

Load/idle and cut-off/continuous mode

If the machine is equipped with load/idle valves, these can be controlled by the AERtronic AS 300. The configured digital output (load valve) takes over the control of the interphase transformer and discharge magnet valve. In idle mode the volume flow on the input side of the compressor is reduced by a suction valve and the pressure side is balanced by a discharge valve.

The machine always switches to idle mode while starting and stopping and during stoppages.

Change of the selected value or the speed in manual mode.Cursor keys appear only after the engine starts up.

Selected value


ENG

LISH

After the start command and expiration of the set run-up time, the machine switches into operation under load.

The system pressure is used as the actual value for the load/idle control. If it exceeds the limit value for Idle pressure the machine automatically switches to idle mode. If the system pressure falls below the Set pressure it switches back to load mode. The parameter minimum idle time in the machine parameter menu causes a delay switching between load and idle and prevents quick switches between loads.

ENG

LISH

The load/idle mode can also be controlled externally by a configured digital input (remote load/idle) or the communication Modbus-/Profibus.

Cut-off modeIf the cut-off operation mode is active the machine additionally switches to standby. It also switches off the main motor and the AERtronic AS 300 remains keyed.

This is indicidated by the standby symbol .

To prevent the main motor from being switched on and off all the time there is a Run-on time in the machine parameter menu. Only after the run-on time is expired and the machine switches to idle mode it is switched to standby. If the system pressure falls below the set pressure the machine is restarted from standby mode and takes over the load mode.

Ctinuous modeIf the continuous operation mode is active, the machine switches to idle mode but does not enter standby mode.

Parameter Range of values / basic settings / notes Parameter

Set pressure

-1.0 16.0 bar default : 0.5 bar

- Set value for PID regulator- If the system pressure falls below this value, the machine

switches into operation under load, the contact of the digital output "On-load" closes, and the solenoid valves are triggered.

- If the system pressure falls below this value, the machine starts from Standby mode. The parameter "Cut-off mode" must be selected under "Control system Miscellaneous".

User

Idling pressure/Max. pressure

-1.0 Maximum machine pressure (machine parameters)default : 0.7 bar

- If the system pressure exceeds this value, the machine switches into idling mode when there is load/idling regulation. The contact of the digital output On-load opens.

- If the system pressure exceeds this value, the analog speed output Pressure regulation is set to 0.

User

Speed setpoint

Auto / Manual / External default : Auto

- Auto: The internal PID controller is in Automatic mode and with the aid of the analog speed output Pressure regulation attempts to keep the system pressure constant. See also parameter Set pressure

- Manual: The internal PID controller is in Manual mode. After the start and run up of the machine, the speed can be changed using the cursor keys in the Selected value screen.

- External: The speed can be preset via an externally active 4-20mA signal. To do this, an analog input must be configured as Ext. allocation. In this context, 4mA=0%=min. speed and 20mA=100%= max. speed.

User

- None: The PID controller is inactive- Discharge side: The internal PID controller regulates

the discharge side of the machine.- Intake side: The internal PID controller regulates the

intake side of the machine. The setting is used with vacuum machines.

P-portion

0 100%default:50%The P-portion represents the proportional part of the PID controller. If this parameter is increased, then the step response (controller output or speed) with an actual value change (system pressure) is accordingly higher. The P-portion is thus only proportional to the actual value signal. P-portion = Controller response = Controller faster

User

I-portion

0 100%default:20%The I-portion represents the integral portion of the PID controller. If this parameter is increased, then the control speed of the controller output (speed) also increases when there is a regulation variance (fference between set pressure and system pressure). The I-portion is thus integrated in terms of timing with the controller output as long as there is a regulation variance.

I-portion = regulation speed = controller faster

User

D-portion

0 100%default:0%The D-portion represents the differential portion of the PID controller. The D-portion does not react to a regulation variance (difference between set pressure and system pressure), rather, only to its rate of change. Thus, the faster the system pressure changes, the higher is the controller output (speed).With normal pressure controllers, this D-portion is usually zero.D-portion = Controller response to changes in actual value = Controller faster

User

Switch-on temperatureHeating

-20 120Cdefault : 0CIf the Ambient temperature drops below this set value, the contact of the digital output Heat is closed and the heat is thereby switched on. This function is active both the when the machine is stopped and during operaiton. The following parameters absolutely must be set:

- An analog input must be parameterized to "ambient temperature".

- A digital output must be parameterized to Heat.

User

16.2 Connection example for the digital inputs

A42: A01-DI1 EMERGENCY STOP permanently assigned input for the connection of an EMERGENCY STOP device supplied by the customer. If this input is not used, a wire jumper should be installed from X3.1 to X3.2, because otherwise the fault message E002 Emergency Stop is active. Note: The input does not correspond to the EMERGENCY STOP function according to DIN EN 60204-1

A42: A01-DI2 Input for motor protection device of the main motor, 0-signal triggers a cut-off or malfunction. If this input is not used, a wire jumper should be installed from X3.1 to X3.3, because otherwise the fault message E003 Main motor overload is active.

A42: A01-DI3 Remote start / stop of the rotary piston machine, 1-Signal = Start, 0-Signal = Stop.

Comment: If the machine fails due to a malfunction, the start signal must be set to 0. If all faults are cleared and the machine is ready to start again, it is possible to restart via this digital input. This prevents an inadvertent starting of the machine after a malfunction is acknowledged.

Attention: The illustration is only one wiring example. The exact wiring can be seen in the respective circuit diagram.

A45: A02-DO1 Collective fault message, contact closed if there is no malfunction. Contact open with pending malfunction also results in an open Line protection contact. The main motor is switched off.

A45: A02-DO2 Collective warning message, contact closed if there is no malfunction. Contact open with a warning pending has no effect on the Line protection output while the machine is running but prevents the restart when stopped.

A45: A02-DO3 Message of readiness for operation, contact closed if there is no warning / no malfunction / no starting block. With the closed contact, the machine is ready to start. Important: The contact also remains closed when the machine is running and opens only when there is a malfunction or a stop command.

16.4 Connection example for activating a frequency converter

A47: A04-AI1 System pressure, actual value for PID controller. If the controller is activated (refer to menu Regulation with PID controller), an attempt is made using the analog output Set value frequency converter to keep the system pressure equal to the set pressure. Example: If the system pressure falls below the set pressure , the speedpreset is increased If the system pressure increases above the set pressure, thespeed preset is reduced

A47: A04-AI2 If the speed preset is not to be made via the internal PID controller, they can also be externally predetermined. In so doing the parameter Speed set point" must be set in the menu (Main menu Control system Regulation) to external. Then the speed preset is carried out by the AERtronic and at this analog input and output again at the A011-A01 output.

Attention: A speed preset is not possible in idling mode and with the machine turned off.

A51: A011-AO1 Frequency converter set value, the speed for the frequency converter is preset here. The output signal 4mA 20mA presets the minimum maximum speed in the range. This means a mandatorily required limitation of the minimum and maximum speed in the frequency converter. Operation outside of these speeds would result in damage to the machine.

Attention: In idling mode and with the machine switched off, 4mA (0%) is output. The analog output emits the correct signal only after the engine is started and up to speed.
