Pump Control/Protection Panel of a single submersible pump. Options for Single Phase or Three Phase. This Controller can function in either an automatic or manual configuration.

The Quadri can control up to two pumps, and is able to balance the workload by alternating the starts of each pump (unless demand requires both pumps be activated simultaneously). The Quadri uses float switches/level probes and/or pressure switches to determine if single or both pumps are required.

The Quadri can run in three modes:

• Boosting
• Storage
• Sewage

Boosting allows the Quadri to function with a pressure boosting system, using both probes and pressure switches to monitor and run pumps when a pressure or level drop is detected.

Storage allows the Quadri to monitor the levels in two tanks, and function as a level controller.

Sewage allows the Quadri to use float switches to determine levels inside a tank and pump according to the parameters set by the installer.

Advantages

Operational parameters can be viewed n the LED’s and edited on the potentiometers on the circuit board.
This allows the Quadri to display system information such as:

• The operational status of the motor
• Error messages
• Defined parameters of operation

Benefits

• Pump Balancing
• Adjustable Settings
• Durable ABS Contruction
• High Quality Electronics
• IP55

Application

The Mac3 3F Controls are a DIN socket mounted, adjustable under-voltage monitoring and protection relays intended for use in control panels.

Mod.22 is Single Phase.

Mod.33 is Three phase with additional phase loss protection.

Advantages

Low voltage leads to increased current and excess heat generation in induction motors causing damage or reducing the life of coils and bearings. Low voltage may be caused by poorly functioning generators, and other temporary power systems, inadequate cable sizing especially temporary wiring or wiring in remote locations such as outbuildings, or poorly specified over-current protection allowing a circuit to be loaded by other appliances beyond it’s proper capacity. Hence under-voltage protection helps to protect important appliances from premature failure avoiding expensive down-time.

Benefits

Both 3F Controls isolate the system if:

• The system voltage drops up to 2.5% of the set value for more than 2 seconds, or
• The system voltage drops more than 2.5% of the set value at all.

A 2 second delay, built into the relay, ensures temporary voltage drops in the electricity supply do not trip the system, while preventing potential pump damage should the condition continue.

The 3F Control Mod. 33 also monitors for phase loss and incorrect phase rotation. This can be due to wiring the phases incorrectly or issues arising from the supply itself, but either condition will cause the 3F Control Mod. 33 to isolate the system until the error is rectified.

Pump Control/Protection Panel of a single submersible pump. Options for Single Phase or Three Phase. This Controller can function in either an automatic or manual configuration.

It can be used with a float switch for drainage and tank filling applications, or with a pressure switch for direct pressure systems.

Advantages

The Quadri CosPhi utilizes CosPhi monitoring of the motor itself, combined with the use of either a float switch or pressure switch to monitor pump function. The Quadri Dry Control Plus activates the pump when required to maintain pressure in the system. If there is a fault or error with the pump, the Controller will
turn the pump off. The Unit therefore prolongs the overall life of the installation.

Benefits

• No need for level probes it is therefore particularly suitable for deep wells.
• Thermal Overload Protection
• Over and Under Voltage Protection
• Adjustable Settings
• Durable ABS Contruction
• High Quality Electronics
• IP55
