Note
All external cables to be connected to the rear panel should be
ended with cable lugs
.
•
Analog output: Connect an external recorder with a 2-wire
cable to these terminals (#2 on page 7) paying attention
to the correct polarity. A wide variety of output signals,
either in V or in mA, is available to fit most standards.
•
Contact 1 and 2: Connect the dosing devices to these terminals (#5 and #8 on
page 7) in order to activate and deactivate them according to the selected control
parameters.
•
mA Input: to switch to mA input signal from a conductivity
transmitter (e.g. HI8936, HI98143 or HI98144 series) see
setup procedure (code 6). Connect the two signal wires from the
transmitter to terminals #12 on page 7, paying attention to the
correct polarity.
An unregulated 10 to 30 VDC - 50 mA max. power supply output
(#11 on page 7) is provided to power the transmitter, if needed.
Once the installation is completed, select the appropriate working range, the reference
temperature (20 or 25 °C) and perform conductivity or TDS calibration as described in
this instruction manual. Set the control parameters according to the process.
