Flexibility and adaptability are key factor when designing a machine. The possibility to change the application parameter during operation such as for example the speed of a cylinder or the force generated by a rotary actuator are beneficial to the designer. In the past it was necessary to design complicated pneumatic circuits based on pneumatic logic elements which required a lot of space and complicated set up, today, thanks to the electronic proportional regulators such operations are extremely easy to achieve and offer even more flexibility. Pneumax miniaturized proportional regulators series integrates all the main features of the 521 series with the exclusion of the display and analogue/digital output. High precision in pressure regulation, fast response speed, assembling options and reduced dimensions are the main advantages. * Request during ordering process Operational characteristics Linearity Hysteresis Repeatability Sensitivity Assembly position Protection degree Environment temperature < ± 0,3 % F.S. <0,3 % F.S. < ± 0,5 % F.S. < ± 0,5 % F.S.

This parameter allows the automatic switch-off of the control solenoid valves for up to 20 seconds to be enabled. This function is used to safeguard the solenoid valves over time. The protection is triggered if the desired pressure is not reached and the outlet pressure does not undergo significant variations within a 4-seconds control of the solenoid valves. A significant variation is defined as a variation that is greater than the defined insensitivity value, parameter P1. After the 4 seconds have elapsed in which the regulator attempts to reach the desired pressure, the protection is triggered. This protection switches off the solenoid valves for a maximum of 20 seconds. If the 20 seconds have elapsed or if during the 20 seconds during which the solenoid valves are switched off the required pressure (reference) varies or the outlet pressure varies the regulator will again start to control the solenoid valves for another 4 seconds, trying to reach the desired pressure. If this does not occur, the protection is reactivated. From this point on 4 seconds of controlling the solenoid valves and 20 seconds of switch-off alternate cyclically.
