• In addition the value before the last reset is saved� This value can also be displayed� The meter saves the totalled consumed quantity every 10 minutes� After a power failure this value is available as the current meter reading� If a time- controlled reset is set, the elapsed time of the set reset interval is also saved�...
4.5 Volumetric flow or temperature monitoring / switching function OUTx changes its switching state if it is above or below the set switching limits (SPx, rPx)� The following switching functions can be selected: 4.5.1 Hysteresis function Normally open: [OUx] = [Hno] Normally closed: [OUx] = [Hnc] First the set point (SPx) is set, then the reset point (rPx) with the requested...
4.6 Volumetric flow or temperature monitoring / analogue function • Analogue start point [ASP] determines at which measured value the output signal is 4 mA� • Analogue end point [AEP] determines at which measured value the output signal is 20 mA� Minimum distance between [ASP] and [AEP] = 25 % of the final value of the measuring range�...
The unit can be set to different standard conditions: • Via the menu item [rEF�P] the standard pressure is set, which serves as a refer- ence for the measured and display values for volumetric flow (→ 9.5.8). • Via the menu item [rEF�T] the standard temperature is set, which serves as a reference for the measured and display values for volumetric flow (→ 9.5.9).
• If compressed air is fed into the main pipe through parallel pipes, the unit should be mounted in the main pipe� • Installation downstream of the maintenance unit is also possible (if oil is used for the loads, the units must be mounted upstream of the oiler)� 5.2 Installation conditions Recommendation: ►...
