INITIAL PREPARATION & INSTALLATION
Material needed:
• a 3-wire power cable (to connec the
HI 8931
)
• a PVC insulated 4-core cable (to connect the
HI 8931
to
HI8936
)
• rubber seals and a pipe sealant (for installation of
HI 7635
)
INPUT FROM TRANSMITTER (HI8931 & HI8936)
• Remove the 4 screws and the top of the
HI 8936
conductivity trans-
mitter.
• Connect the 2 wires connected to
the "4-20mA" and "COM" termi-
nals of the 4-core signal cable
from the
HI 8936
to the termi-
nals marked "mA input" paying
careful attention to polarity.
Connect the other 2 wires to the
"+20 V" and "COM" terminals,
while paying attention to the
polarity.
