CONNECTIONS
REAR CONNECTIONS FOR HI 8931
• Power Connection Terminals
4-screw-terminal-strip for connection
to a 3-wire power cable according to
the indicated voltage (115 or 230V).
• IN/OUT Transmitter
2 wires of the 4-core signal cable
from the conductivity transmitter
(HI8936) have to be connected to
the mA input terminals and the
other 2 wires to the "+20 V" and
"COM" while paying careful atten-
tion to the polarity.
+20 V supply is the regulated DC supply required for the
operation of the external conductivity transmitter HI 8936.
• Set Contacts
Dosing pumps or other control equip-
ment may be connected to the "SET"
(Max. 2A, 240 V) terminals. These
contacts act only as a "dry" switch
allowing electrical continuity, not as
a power supply.
