Controller models
Dear Customer, thank you for choosing Hanna Instruments.
HI520 is a universal process controller intended for applications where
simultaneous measurement and control of process variables is needed.
Main features
• Hanna Smart digital probes
• RS-485 / Modbus serial communication protocol
• Independent / sequential channel control
• Flexible function assignment for control, cleaning, Hold relays
• IP65 / NEMA 4X protection
• Wall, pipe, panel mounting kit (sold separately)
Safety precautions
• Electrical connection must be carried out by specialized personnel
only. Read safety manual instructions before connecting to power.
• Do not make electrical connections with device connected to power.
• Do not run other cables through the designated power cable gland.
• Have a disconnect switch installed in the vicinity of the instrument
to ensure electrical circuit is de-energized for installation.
Opening the enclosure
• Loosen the four screws, enough for the springs to push them out.
• Grasp the front bezel and swing open to access the two-
terminal power supply board.
Connecting to power
• Remove the blank plug and thread the cable through the power
cable gland.
• Remove the safety cover to access high voltage Terminal 1.
• Connect the probe leads to the terminal connector POWER.
Follow lead markings for correct wiring on the supply
board. Each leads location is marked.
• Ensure the power connector is seated correctly in the power socket.
• Replace safety cover over Terminal 1.

Controller wiring
• Terminal 1 (high voltage): POWER, ALARM, REL 1 to REL 5
(relays)
• Terminal 2 (low voltage): COMM (RS-485), PROBE1 and
PROBE2, IN1 and IN2 (digital inputs), A01 to A04 (analog
outputs)
• Follow lead markings to ensure output leads are wired
to the correct position on the main board.

Probe wiring
1. With controller disconnected from power run the probe cable
through the correct conduit opening.
2. Connect probe leads to the terminal connector PROBE1 or PROBE2.
Follow lead markings for correct wiring of output leads.
3. Carefully put the wired terminal connector into place on the board.
4. Position excess cable through cable gland before tightening the nut.
5. Remove the ground screw and hardware located below the probe
connector. Attach the ground lead ( g).
