Definitions
- the invention relates to a method for checking the functionality of a control device, with a control valve which is adjustable via an actuator by means of an actuating element acting on the control valve, a position encoder, which detects the actual position of the control element, and an electro-pneumatic positioner which generates a pneumatic manipulated variable as a function of the actual position and a setpoint position, which is supplied to the actuator via an activated solenoid valve which can be deactivated for venting the actuator, the actuator being briefly actuated via a partial stroke test moves a part of its travel while the adjusting movement is detected and for testing the solenoid valve this is briefly deactivated, so that the actuator moves ment only over part of its travel.
- the solenoid valve To test the solenoid valve, it is temporarily deactivated by interrupting its power supply, thereby monitoring the pressure difference between the side connected to the positioner and the side of the solenoid valve connected to the actuator. The test of the solenoid valve is considered successful if, during the short-term deactivation n
- the invention has for its object to simplify the review of the functionality of the actuator, which also can be dispensed with special pressure sensors and corresponding pneumatic connections to the positioner or the solenoid valve.
- this object is achieved in that in the method of the type specified, the partial stroke test and the test of the solenoid valve in a single test procedure by the solenoid valve is deactivated, detects the actuating movement of the actuating element and upon reaching a predetermined Path change is monitored and when the predetermined path change the solenoid valve is activated again.
- the actuator When deactivating the solenoid valve, the actuator is pneumatically separated from the positioner and vented instead, so that the pressure in the actuator is reduced and the actuator with the control valve, for example, under the action of a spring in the actuator, moves.
- the solenoid valve is reactivated and the positioner controls the actuator via the actuator back to its original position. In the single test procedure so the functionality of all parts of the actuator including the solenoid valve is tested.
- the actuating movement detected during the test procedure and / or the path change achieved are stored.
- the time required for deactivation of the solenoid valve until reaching the predetermined path change can be detected and stored.
- test progress is logged and it can be determined whether the actuator responds quickly enough to changes in requirements.
- the solenoid valve is activated again when the time interval is exceeded ,
- the test can be automatically initiated, monitored and evaluated by an I & C device outside the actuator.
- the computation cycle times of control technology devices are generally too long to directly control and evaluate the sequence of a partial stroke test.
- the solenoid valve receives from the process control device a supply voltage which can be switched off in an emergency of the control device, and that the supply voltage is supplied to the solenoid valve via a controllable switch, which for starting and Termination of the test procedure is opened or closed by the positioner.
- the actuator is moved to the control valve in a safety or emergency position, while the test of the actuator is controlled and monitored by the faster compared to the process control device positioner.
- the positioner can be triggered by the process control device to start the test procedure and, after the test procedure, communicate the test results to the process control device.
- FIGURE of the drawing shows an ⁇
- the actuator 1 includes a pneumatic actuator 2, which operates via a control element 3, here in the form of a lifting rod, a control valve 4 and thereby controls the fluid flow in a pipe 5.
- the actuator 2 is connected via a pneumatic line 6 with a solenoid valve 7 disposed therein to a positioner 8, which is fed from a supply line 9 with compressed air.
- a position sensor 10 detects the actual position of the control element 3 and supplies it to the positioner 8, which adjusts a variable pressure in the line 6 in response to the actual position and a predetermined desired position as manipulated variable to the actuator 3 with the Valve 4 to move to the desired position.
- the positioner 8 is connected via a communication line 11 to a control device 12.
- the solenoid valve 7, which may be disposed within the actuator 1 or outside of it, is designed as a three-way valve and receives from the control device 12 via a line 13, a supply voltage Vs supplied.
- the supply voltage Vs is turned on, so that the solenoid valve 7 is activated and pneumatically connects the positioner 8 with the actuator 2.
- the control device 12 switches off the supply voltage Vs, so that the then deactivated solenoid valve 7 separates the actuator 2 from the positioner 8 and instead vented via a solenoid valve outlet 14.
- the actuator 2 is then depressurized and moves the actuator 3 with the valve 4, for example, under the action of a spring in the actuator 2, in a safety position.
- the deactivation and subsequent reactivation of the solenoid valve 7 can also be made on the actuator 1 itself by a controllable switch 15th ⁇
- the control device 12 For regular checking of the functionality of the actuator 1, the control device 12 is automatically each time a corresponding command via the communication line 11 to the positioner 8 from. This then generates a control signal to open the controllable switch 15, so that the solenoid valve 7 is deactivated and as a result of the actuator 2 is vented.
- the subsequent onset of movement of the control element 3 is detected by the position sensor 10 and stored in a memory 16 of the positioner 8.
- the positioner 8 monitors the adjusting movement of the actuating element 3 to achieve a predetermined parameterizable path change and generates when reaching the predetermined path change a control signal to close the controllable switch 15, so that the solenoid valve 7 is reactivated and the pneumatic connection between the positioner 8 and the Actuator 2 is restored.
- the positioner 8 now controls the control element 3 with the control valve 4 back to the starting position before the test, whereby now also the adjusting movement is detected and stored.
- the times are also detected that the actuating element 3 requires from deactivating the solenoid valve 7 until reaching the predetermined path change and subsequently from reactivating the solenoid valve 7 until reaching the starting position before the test.
- the time required for deactivation of the solenoid valve 7 to reach the predetermined path change is monitored for exceeding a predetermined, also parameterizable, time span and the solenoid valve 7 is reactivated when this time span is exceeded in order, in the event of a fault, for example if the actuating element gets stuck, to prevent permanent ventilation of the actuator 2.
- a predetermined, also parameterizable, time span is monitored for exceeding a predetermined, also parameterizable, time span and the solenoid valve 7 is reactivated when this time span is exceeded in order, in the event of a fault, for example if the actuating element gets stuck, to prevent permanent ventilation of the actuator 2.
- the positioner 8 transmits the test results, that is the stored positioning movements and associated times to the process control device 12.
- the test results transmitted during successive tests of the actuator 1 can be compared and analyzed for trend changes, so z. B. to diagnose increased wear in the actuator 1.
