Pulse-signal PNP / PNP-LP:
The ER-420 is suitable for use with flowmeters which have a PNP output signal 3 2V is offered on terminal 11 which has to
be switched by the sensor to terminal 10 (SIGNAL) For a reliable pulse detection, the pulse amplitude has to go above 1 2V
Signal setting PNP-LP employs a low-pass signal noise filter, which limits the maximum input frequency (see "Details of Setup
Functions" on page 15 )
For a signal detection level of 50% of the supply voltage, see "Terminal 05-06; scaled pulse output R1:" on page 25
Active signals 8.1V to 12V and 24V
If a sensor gives an active signal, see "Details of Setup Functions" on page 15 The detection levels are 50% of the selected
supply voltage; approximately 4V (ACT_8 1) or 6V (ACT_12) or 12V (ACT_24)
