Active signals 8.2V and 24V
The E115-P is suitable for flowmeters with an Active signal. The detection levels are about 50% of
the selected supply voltage; approximately 4V (ACT_8.1) or 12V (ACT_24). See paragraph 3.3.7 for
more information.
Active signal selection may be desired in the case of power supply type PD being supplied for
sensor supply.

4.6.4 TERMINAL E1-E2 – EXTERNAL RESET WITH CLEAR-LOCK – TYPE IB
With this function the total can be reset to zero with an external switch. The total resets at the
moment a falling edge is detected (the moment the switch closes).
To disable the function ”Clear Total” through the glass (IR keys - see chapter 2), keep this input
closed.
Make sure the contact resistance of the switch is less than 0.8V@2uA=400k Ohm. A reset pulse
should last for at least 200ms
The input must be switched with a normally open contact to GND.
