REAR CONNECTIONS FOR HI 8410
• Power Connection Terminals
4-screw-terminal-strip for connection to
a 3-wire power cable according to the
indicated voltage (115 or 230V).
• Probe Connection
For connection of the
HI764
09
DO
probe. Connect the wires according with
the indicated color.
• Range Selection
To select mg/L range make a short with
a jumper wire between the terminals (1,
2). To select % DO range leave termi-
nals 1, 2 unconnected.
• Set Contacts
Dosing pumps or other control equipment
may be connected to the "SET" (Max.
2A, 240 V) terminals (3, 4). These
contacts act only as a "dry" switch
allowing electrical continuity, not as a
power supply.
• Alarm Contacts
(terminals 5, 6)
During normal operation these terminals
remain closed.
If the measured DO level is not within
the tolerance of the set value, the alarm
contact is open. These contacts act only
as a switch. See also page 15.
•
Recorder Output
(terminals 1, 2, 3)
These contacts are used for connection
to a recorder output. The output can be
0-20 mA or 4-20 mA and is proportional
to the measured Dissolved Oxygen values.
