15. 4~20mA TRANSMITTERS
Depth sensors: Global Water’s WL400, WL450, etc.
PH sensors: Global Water’s WQ201, etc .
CONNECTION:
Connect the first sensor to screws 8 [+BAT Ext] on the right screw
terminal and 3 [CH2] on the left screw terminal.
Connect the second sensor to screws 8 [+BAT Ext] on the right screw
terminal and 4 [CH3] on the left screw terminal, etc.
Wire polarity does matter (see drawing): For the WL450 depth sensor, the
red wire of the sensor connects to screw 8 [+BAT Ext] on the right screw
terminal. The black wire of the sensor connects to an analog channel only.
For connection of other sensors (depth sensors and pH sensors), and their
setup, see the table below.
ATTENTION: Always connect the sensors without external power supply.
IN CASE IT DOESN’T WORK:
Make sure that the ANALOG input is
configured as current and that the +VA
PULSED output is setup for 12V or 18V.
With the sensor connected to the logger,
select from the main menu:
SETUP>MODE>CONTINUOUS> [ENTER]
With a multimeter check the current in series
with one of the sensor’s wires: it should be
4mA or greater.
