Anleitung Zusammenfassung
If the condensate volume deviates from the set values (see 4.6.1.6) the adaptation to the specific characteristics of compressed air system is possible (see 4.6.1.6) Once the container has filled with condensate, so that the capacitive level sensor emits a signal, the internal solenoid valve opens and the condensate is forced by the working pressure into the discharge pipe. The condensate drain electronic system ensures the closing of the outlet opening before any compressed air can escape. For functional safety a minimum pressure of 2 bar is necessary. 1 2 3 Alarm Test Power Alarm Test Power Alarm Test At faulty condensate discharge (blocked discharge pipe, pressure below minimum operating pressure), the unit changes to the alarm control after 60 seconds.The green LED flashes and a potential-free contact is activated. While in alarm control mode, the solenoid valve will open every 4 minutes for a period of 7,5 seconds, in order to remove any possible obstructions in the discharge pipe automatically. A unit filled during a pressureless state will additionally be emptied automatically, as soon as the minimum pressure within the condensate drain has been reached. 16 11.02 Part 4 Operation Part 4 Operation 4.1 Commissioning 4.2 Starting 4.3 Operation 4.4 Stopping After installation the CA-dryer is supplied with power via the power cable (fig. 5/1) or by operating the main switch (fig. 5/13). Before operating the operation switch (fig. 3/14), a waiting period of at least 6 hours is absolutely necessary. The CA-dryer is switched on via the operation switch (fig. 5/14). After approx. 5 minutes the compressed air admission is possible by connecting the compressed air compressor. The CA-dryer is designed for continuous operation and may remain switched on during periods of no load, as it adapts to the required performance automatically. Operation is indicated by the luminous operation switch (fig. 5/14). The electronic regulator shows the pressure dew point reached by the CA-dryer. At standstill periods, the CA-dryer is switched off with operation switch (fig. 5/5). For service works, the CA-dryer is switched off by pulling the power cable (Fig 5/6). At restarting proceed acc. to item 4.1. 1711.02 18 11.02 Part 4 Operation Following operation data can be recalled by operating the data selector key ( ): - Pressure dew point - Summer operation - Percentage running time of CA-dryer in relation to total running time of the system - Next condensate drain in 3 minutes 1.
