3. Safety Information

WARNING: Electrical shock hazard. Installation and maintenance should only be performed by qualified personnel.

• Always disconnect power before installing, servicing, or performing any maintenance on the controller or connected pump.
• Ensure all wiring connections are secure and comply with local electrical codes.
• Do not operate the controller with damaged wires or components.
• Keep the controller unit dry and protected from direct water exposure.
• This device operates on 220V AC. Exercise extreme caution.

4. Setup and Installation

4.1. Dimensions

Before installation, ensure adequate space for the controller unit. Refer to the dimensions below:

Image 2: Detailed dimensions of the ZTBH DF-96DK controller unit. The unit measures approximately 86.5mm in length, 35.3mm in width, 66.7mm in height, with a top section width of 45.6mm and a terminal block height of 23.4mm.

• Length: 86.5 mm
• Width: 35.3 mm
• Height: 66.7 mm

4.2. Wiring Diagram

Connect the controller according to the following wiring diagram. Ensure all connections are correct and secure.

Image 3: Wiring diagram for the DF-96DK controller. It shows input (L, N) connected to the controller, and output connected to a load (e.g., a pump) via a contactor (CJX2 1810). The probes (A, B, C, D, E) are connected to the controller's terminals for water level sensing.

1. Connect the 220V AC power supply to the input terminals (L and N) of the controller.
2. Connect the output terminals of the controller to the control circuit of your pump (typically through a contactor, as shown in the diagram).
3. Install the three water level sensing probes (A, B, C) at the desired water levels.
   • Probe A: High water level (pump OFF when water reaches this level).
   • Probe B: Low water level (pump ON when water drops below this level).
   • Probe C: Common ground probe (always submerged).
4. Ensure probes are securely fastened and insulated from each other.

5. Operating Instructions

Once the controller is correctly installed and wired, follow these steps for operation:

1. Power On: Ensure all connections are secure, then apply 220V AC power to the controller.
2. Mode Selection: The controller typically has an automatic mode. The red switch on the unit is likely for manual override or power control.
3. Automatic Operation:
   • When the water level drops below Probe B, the controller will activate the connected pump.
   • When the water level rises and reaches Probe A, the controller will deactivate the pump.
   • Probe C must remain submerged for continuous operation.
4. Manual Override: If available, use the manual switch (red switch on the unit) to manually turn the pump ON or OFF, bypassing the automatic level detection. Refer to the markings on the unit for specific switch functions (e.g., "开" for ON, "关" for OFF, "自动" for Automatic).

6. Maintenance

Regular maintenance ensures optimal performance and longevity of your water level controller:

• Inspect Probes: Periodically check the water level sensing probes for corrosion, dirt, or damage. Clean them as necessary to ensure accurate readings.
• Check Connections: Ensure all electrical connections remain tight and free from corrosion.
• Clean Unit: Keep the controller unit clean and free from dust and debris. Do not use abrasive cleaners or solvents.
• Environmental Protection: Ensure the controller is protected from extreme temperatures, direct sunlight, and moisture.
