F F PZP-830 Submersible Pump Control Relay

Specifications:

• Model: PZP-830
• Type: Submersible pump control relay
• Designed for 1-phase drives of submersible pumps up to 2.2 kW

Product Usage Instructions

Functionality:
The PZP-830 controller is designed for comprehensive control of submersible pumps. It works with probes immersed in the well and a sensor to signal tank overfilling.

Starting the Pump:
Ensure the tank is not overfilled and all conditions are met. If using a tank overfill sensor, connect it; otherwise, short the FULL terminals. Start the pump, being aware of potential inrush currents.

Operation Cycle:
The pump will start when the R2 level in the well is exceeded for a set time. It will run until the tank overflows or the water level drops below R1.

Mounting:

1. Turn off the power supply.
2. Fix the relay on a rail in the switchboard.
3. Place liquid-level probes in the well and connect them to the controller as per the diagram.
4. Connect the tank fill sensor to the FULL terminals. Short the terminals if not using a sensor.
5. Connect the ON/OFF switch for control.
6. Connect the power supply to L IN and N terminals.
7. Connect the motor to the L OUT and N terminals.
8. Ground the motor and pump housing. Do not connect voltage to ON/OFF and FULL terminals.

FAQ:

• Q: What should I do if inrush currents occur when starting the pump?
  A: Inrush currents are normal but if they exceed set parameters, the motor will stop. Check parameters P7 and P8.

• Q: Is there an automatic restart option?
  A: Yes, there is an automatic restart if pump operation is interrupted due to set conditions being exceeded. Check parameters P6 and P9.

• Q: What happens when the R2 level is exceeded in the well?
  A: The pump will trigger and operate until the tank overflows or the water level drops below R1. The controller will wait for conditions to start the next cycle.

Do not dispose of this device in the trash along with other waste!
According to the Law on Waste, electro comes from households free of charge and can give any amount to up to that endpoint of collection, as well as to store the occasion of the purchase of new equipment (per the principle of old- for-new, regardless of brand). Electro thrown in the trash or abandoned in nature, pose a threat to the environment and human health.

Purpose

The PZP-830 controller is designed for comprehensive control of 1-phase drives of submersible pumps up to 2.2 kW.

Features

• Controlling the water level in the well;
• Overfill protection for the tank to be filled;
• Control of the correctness of the supply voltage;
• Detection of high motor operating current (overload);
• Detection of low motor operating current (dry-running);
• Motor startup control.

Functioning

The controller is adapted to work with 2 (or 3) probes immersed in the well, plus a sensor (for example, a float) with a contact output to signal the overfilling of the tank.

Conditions for starting the pump

For the first 4 seconds after the power is turned on, the controller controls the conditions based on which it will decide whether to start the pump:

• whether an operation command (closed external ON/ OFF contact) is issued;
• whether the supply voltage is in the correct range;
• whether the water level in the well exceeds R1;
• whether the sensor does not indicate overfilling of the tank to be filled (open FULL input).

If all the above conditions are met, the pump is started.

WARNING

• If the tank overfill sensor will not be used, the FULL terminals should be shorted.
• If the controller is to work only with 2 well-fill probes, the higher-mounted probe should be connected to both R1 and R2 terminals.

Starting the pump

WARNING
When the pump is started, inrush currents may occur that are several times higher than the rated value.

To ensure the correct level of motor protection also for this case, 2 additional parameters are programmed in the controller:

• the ratio of inrush current to rated current (parameter P7);
• duration of motor startup (parameter P8).

WARNING
When the startup is heavier than that set by parameters P7 and P8, the motor will be stopped.

Pump operation control

During pump operation, the controller continuously checks the parameters of the supply voltage and the current flowing through the motor.
Security configuration is done through settings:

• maximum voltage (parameter P1);
• maximum current (parameter P2);
• minimum voltage (parameter P3);
• minimum current (parameter P4);
• current protection tripping delay (parameter P5).

If the preset operating conditions are exceeded, the pump will be stopped.

WARNING
There is an option of automatic restart in case the operation of the pump is interrupted due to exceeding the set operating conditions (voltage and current). The time to automatic restart can be set by parameter P6, while the number of automatic attempts to clear the error is set by parameter P9.

Operation cycle

Exceeding the R2 level in the well for the time set by parameter P10 will trigger the pump (taking into account the previously mentioned conditions). The pump will remain on until the tank overflows (FULL sensor opens), or until the water level in the well drops below R1. After shutting down, the controller waits for conditions to be met for the next cycle of operation.

Mounting

1. Turn off the power supply.

2. Fix the relay on a rail in the switchboard.

3. Place liquid-level probes in the deep well and connect them to the controller according to the diagram below.

4. Connect the tank fill sensor (for example, float) to the FULL terminals of the controller. If this sensor is abandoned, the FULL terminals must be shorted.

5. Connect the ON/OFF switch to set the work command.
   Under no circumstances should the voltage be connected to the ON/OFF and FULL terminals. This can lead to da-mage to the controller!

6. Connect the power supply to the L IN (phase wire) and N (neural wire) terminals.

7. Connect the motor to the L OUT (phase wire) and N (neutral wire) terminals.

8. Ground the motor and pump housing. Failure to ground the motor body can lead to damage to the pump.
   Not applicable to pumps with double-insulated housing and no access to metal parts.

9. Turn on the power the power to the switchboard.

Wiring diagram

Control panel

• Sets the controller in the ready-to-run state (START). In menu mode, it allows you to move from one parameter to another. In edit mode, it increases the value of the edited parameter.
• Turn off the controller (STOP). In menu mode, it allows you to move from one parameter to another. In edit mode, it decreases the value of the edited parameter.
• After pressing the button (MENU), the controller displays the menu with parameters. In edit mode, pressing the button saves the new parameter value and exits the menu.
• In case of an error, pressing the button (RESET) clears the error and allows the pump to restart.. In menu display and parameter editing mode, pressing the button exits the menu without saving parameter changes.

Display

The controller is equipped with a 2-element, 3-digit LED display. During normal operation, the upper display shows the current value of the supply voltage, and the lower display shows the current value of the motor current. In menu and configuration mode, the upper display indicates the parameter number, and the lower display indicates the parameter value.

LED indicators

• Start The controller in the working or ready state.
• Stop Controller off, in Stop mode, the pump will not be switched on.
• Full Tank fill signaling.
• The motor on Signaling that the pump motor is switched on.
