ARI-PACO Actuator
1. Automatic travel adaption
In a manual started initialization run the real valve travel is determined and the control-and the feedback-signals are automatically adjusted. The initialization run is indicated optical and mechanical. With deactivated voltage limitation the initialization run is additional indicated by a 13 Volt feedback signal.
2. Direct control open/stop/close
A priority sequence ensures, that the manual-mode switch to the actuator has always the highest priority before the following direct control and at last the automatic mode. This function guarantees the correct working of the actuator in every operating situation. The direct connection of the frost protection switch without cutting-off the control signal from the actuator is enabled to be done by this function.
3. Manual-mode switching
For safety reasons the actuator is automatically switched in the manual mode by removing the hood. In this mode the actuator doesn’t obeys the automatic control signal or the direct control signal. To get the function checked during the installation, the actuator can be switched back in the automatic mode by an internal magnetic switch. With deactivated voltage limitation the manual mode is indicated by a 13 Volt feedback signal.
4. Variable control-and feedback-signals
The range of the control signal can be switched from 0……10V to 2……10V and also be inverted to 10……0V or 10……2V. The feedback signal 0……10V can also be inverted to 10……0V. If the voltage limitation is deactivated error messages and some specific working modes of the actuator are signalized by a 13V feedback signal.
5. Wearless actual value sensing
The value of the actual valve position is calculated from wearless sensed signals of a reed contact, which is mounted on the motor shaft. Trouble-free durability of the actuator is ensured by this construction.
6. Non-contact motor travel switching
The travel switching in the final positions is done electronically, when the number of counts to get the nominal thrust force is reached. This function also ensures the trouble-free durability of the actuator.
7. Switchable valve blocking-protection
Dependent on the plant process it is possible to activate the blocking-protection. In the activated mode the valve is opened for a short time, after every 24 hours in a closing position without any moving, to protect the soft sealing against sticking to the valve seat.
8. Automatic valve blocking signalising and removing
If a valve blocking is detected, the actuator tries automatically to eliminate the blocking by means of different moving commands. With deactivated voltage limitation this function is indicated by a 13 Volt feedback signal.
9. Dynamic hysteresis
Interferences on the control signal lines are suppressed by the dynamic hysteresis automatically. By this means the actuator and the valve is protected against unnecessary movings and in consequence unnecessary wear and shorter lifetime.
10. Zero crossing
By connecting the neutral lines of the DC control signal and the AC power input, the economic 3-wire-connection is realised. To minimize errors caused by voltage drops of long wires on the control signal Y, the control signal Y is only read in the zero crossing.
