Hanna Instruments HI 8510 Bedienungsanleitung
HI8711 allows the selection of two set points with two independent outputs for acid and alkaline
dosages.
•Auto-diagnostics to verify offset and slope calibration and electrode contamination deterioration
•Fail Safe Alarm System protects against problems caused by power supply failure or signal
interruption
•Selectable manual ON, OFF and automatic dosing control for alkaline and acid dosing with
indicator.
Fail Safe Alarm System
•Hanna’s exclusive Fail Safe Alarm System protects against problems caused by power supply
failure or signal interruption, which are typical risks in industrial environments. An alarm
condition is indicated by a red LED, located directly on the front panel of the controller.
Self-Diagnostic Test
•Built-in autodiagnostic functions enable the user to check and troubleshoot any malfunctions.
The functions are made via front panel keys to isolate the cause of malfunction whether it is due
to pH electrode contamination, internal offset circuit or the amplifier circuit.
Overtime Dosing Protection
•The HI8711 incorporates adjustable overtime dosing protection from 5 to 60 minutes. If dosing
exceeds selected time, the alarm will be triggered and the dosing contact will deactivate. This
feature can be activated or deactivated.
Matching Pin Connection
•Supports potential matching pin connection to avoid typical problems caused by grounding loop
current, such as progressive damage of the electrode, fluctuating measurements, and poor
process regulation.
Output and Input Connections
•Each model accepts either a direct input from a pH or ORP electrode or from a transmitter
through 4-20 mA input. The instrument also provides ±5V power output and input terminals for
amplified electrodes. Moreover, you can choose the output configuration for connecting a
recorder or a PLC, between 0-20 or 4-20 mA.
obust Design
•A removable, transparent splash-proof cover protects the front panel.

PRELIMINARY EXAMINATION
Remove the instrument from the packing
material and examine it carefully to make
sure that no damage has occurred during
shipping. If there is any noticeable damage,
notify your Dealer.
Note: Save all packing materials until you
are sure that the instrument functions
correctly. All defective items must be
returned in the original packing materials
together with the supplied accessories.
GENERAL DESCRIPTION
HI 8510, HI 8512, HI 8710, HI 8711, HI 8720,
HI 931500, HI 931501 and HI 932500 are pH-
ORP panel-mounted indicators and control-
lers designed for simplicity of use in a wide
range of industrial process applications.
The models are designed with DIN standard
panel mount with membrane keypads on the
front panel, a large LCD display and
autodiagnostic functions (not HI 931500,
HI 931501 and HI 932500).
Connections to the power supply, contacts
and recorders are made through screw termi-
nals on the rear panel.
Two models are available for HI 8510, HI 8711,
HI 8512, HI 8520. The E-model accepts input
direct from the pH or ORP electrode, while
the T-model accepts a 2-wire current loop of
4 to 20mA from a pH or ORP transmitter.
HI 931500, HI 931501 and HI 932500 are
equipped with a BNC socket to connect a
pH-ORP electrode.
Other features include: recorder output in 0
to 20mA or 4 to 20 mA; LED indicators
which identify the controller mode.

Using the pH indicators in conjunction with a
4-20mA output pH transmitter HI 8614 or
HI 8614L (with LCD display) and using the
ORP indicators in conjunction with a 4-20 mA
output ORP transmitter HI 8615 or HI 8615L
(with LCD display) will assure you of a strong,
interference-free signal at distances up to
300 m (1000 ft).
All instruments are supplied with a plastic
transparent front cover and mounting brack-
ets (electrode and mains cable excluded).
