4.3.3 Connect frequency signal
You can connect a passive sensor with PNP (= +Ub switched PNP Output,
High-side switch...).when measuring Frequency and Speed (rpm). When
the configuration is "Switch Contact PNP" a Pull-down resistor (~7 kOhm
against GND) is switched-on within the equipment. In this way, senders
with PNP Output and Speed (rpm) can be used without need for an
external resistor. During Frequency and Flow-volume measurements >
2kHz, the enclosed 4.7 KOhm resistor must be connected between pins
10 and 12.
Hint
Check to make make absolutely certain that the permissible input voltage
and/or the permissible input current of the frequency input connection is
not exceeded.
