Operating Manual
7.5.4 Sensors for condensation
The condensation sensor Type SHS delivers a “1“ Signal when condensation has been
detected and a “0“, if no condensation is detected. This connection can be configured
in
LoggerSetup/SensorSlot
- SlotMode:
Condensation [ ].
7.5.5 Pulse Count - potential-free contacts
The YL-M41/42 and the YL-M90 data loggers can process signals from external switch
contacts. The sensors need to be connected to the YY-CS cable. Just connect cable
colours according to the scheme below:
With both asynchronous and synchronous signals a pulse is counted when the
switch is closed.
This connection can be configured in
LoggerSetup/SensorSlot
- SlotMode:
Frequency [Hz].
Important:
Connecting voltages higher than 3 Volts will damage the device.
7.5.6 Pulse Count - Voltage pulses <3Volts CMOS
If the pulse signal is not a voltage-free signal but has a potential,
which is less than
3V
then the standard YY-CS cable can be used. Connect pins 3 and 4 according to the
following image:
With both asynchronous and synchronous signals a pulse is counted on the
falling edge (from high level to low level).
This connection can be configured in
LoggerSetup/SensorSlot
- SlotMode:
Frequency [Hz].
