WARNINGS
All external cables connected to the rear panel should be fitted with cable lugs.
A clearly marked disconnect switch (max. 6A) must be installed in the vicinity of the instrument to
ensure that the electrical circuit is completely de‑energized for service or maintenance.
7.2. REAR PANEL CONNECTIONS
Probe terminal
• Follow color code to connect the probe.
Power supply terminal
• BL9833XX‑0
Connect the 2 wires of a 12 VDC power adapter to the +12 VDC and GND terminals.
• BL9833XX‑1 & BL9833XX‑2
Connect a 3‑wire power cable paying attention to the correct contacts:
• earth (PE)
• line (L), 115 VAC or 230 VAC
• neutral (N1 for 115 V or N2 for 230 V)
Dosing Contact
• Dosing contact (NO) output drives the dosing system as per configured setpoint.

Operations 8
Overtime feature (system control)
•
This feature is provided to set the maximum continuous time the relay is running a
pump or valve, by adjusting the trimmer (from approx. 5 minutes minimum, to approx.
30 minutes maximum).
• When the set time expires, dosing stops, the LED operational indicator turns red (blinking),
and “TIMEOUT” message is displayed. To exit, set the dosing switch to OFF then Auto.
• Remove the jumper from the rear panel to disable the feature.
Note: Ensure the dosing switch (front panel) is on Auto for the Overtime feature to be enabled.
External Disabling Contact (NO)
• Normally Open: dosing is enabled.
•
Closed: dosing stops, the LED indicator turns red (blinking) and the “HALT” warning
message is displayed.
Note: If the dosing switch is ON, dosing continues even with the external disabling contact closed.
Output terminal: 4-20 mA
• Connect process control signal output
8. OPERATIONS
Hanna®EC and TDS mini controller series are intended to be used to control industrial processes. Relays and
Outputs are used to interact with valves or pumps to monitor a process.
8.1. CALIBRATION
1. If the instrument is not in measurement mode, press MEAS key.
2. Immerse the probe in calibration solution. See below table for recommended calibration solutions.
3. Shake briefly and allow reading to stabilize.
4. Adjust the CAL trimmer until the LCD displays the nominal value given here:
Series Calibration Solution Read Value
EC
BL983313 1413 µS/cm (HI7031) 1413 µS
BL983317 5.00 mS/cm (HI7039)5.00 mS
BL983320 84 µS/cm (HI7033) 84.0 µS

9 Operations
8.2. SETPOINT CONFIGURATION
General: a set point is a threshold value that will trigger control if the measurement value crosses it.
1. Press the SET key. The LCD displays the default or previously configured value along with the ”SET“ tag.
2. Use a small screwdriver to adjust the SET trimmer to the desired setpoint value.
3. After 1 minute the instrument resumes measure mode. If not, press the MEAS key.
Note: The setpoint has a typical hysteresis value comparable to the instrument’s accuracy.
8.3. MONITORING
Best practices
• Ensure wiring is done correctly.
• Ensure setpoint value is configured correctly.
• Ensure probe calibration.
• Select dosing mode.
Procedure
1. Immerse (or install) the probe in the solution to be monitored.
2. Press the MEAS key (if necessary). The LCD displays the measured value.
• LED indicator lights up Green indicating instrument is in measurement mode and dosing is not active.
• LED indicator lights up Orange/Yellow indicating dosing in progress.
8.4. PROBE MAINTENANCE
Regular cleaning and correct storage is the best way to maximise probe’s life.
• Immerse the tip of the probe in HI7061 Cleaning Solution for 1 hour.
• If a more thorough cleaning is required, brush the metal pins with very fine sandpaper.
• After cleaning, rinse the probe with tap water and recalibrate the meter.
• Store the probe clean and dry.
