Winding resistance

As the motor is star-connected, the easiest way to measure the winding resistance is to measure across two stator windings.

Measure while the coil temperature is approximately 20°C. It may be necessary to let the motor cool off if it has been running, or if it was stopped because of short-circuit or overload. Measure between terminal T4 → T5, T4 → T6 and T5 → T6.

Motor terminals

Wiring diagram

Shaft seal run-in

The shaft seal faces are lubricated by the pumped liquid. A slight leakage from the shaft seal of up to 10 ml per day or 8 to 10 drops per hour may occur.

When the pump is started up for the first time, or when the shaft seal has been replaced, a certain run-in period is required before the leakage is reduced to an acceptable level. The time required for this depends on the operating conditions, that is, every time the operating conditions change, a new run-in period will be started.

Under normal conditions, the leaking liquid will evaporate. As a result, no leakage will be detected.

If the unlikely event of an internal leakage occurs, the liquid will be drained through the bottom of the pump. Install the pump in such a way that no undesirable collateral damage can arise.

Fault finding

Electric shock
Death or serious personal injury

• Before starting any work on the product, make sure that the power supply has been switched off and that it cannot be accidentally switched on.

Fault resetting

You can reset a fault indication in one of the following ways:

• When you have eliminated the fault cause, reset the pump manually by pressing the Reset button. The pump will then revert to normal duty.
• If the fault disappears by itself, the pump will attempt to reset automatically and the fault indication will disappear if automatic reset is successful and provided that you have enabled the auto reset function in the service menu.

The pump is not running

Grundfos Eye: No lights are on.
Cause	Remedy
Power supply failure.	Switch on the power supply. Check the cables and cable connections for defects and loose connections. Check for blown fuses in the electrical installation.

The pump is not running, and indicator light 1 is on

Grundfos Eye: Two opposite green indicator lights are permanently on.
Indicator light 1 is on, indicating power supply failure.
Cause	Remedy
The power supply is out of prescribed voltage range.	Check the power supply and the pump nameplate. Reestablish the power supply within the prescribed voltage range.

The pump is not running, and indicator light 2 is on

Grundfos Eye: Two opposite red indicator lights are flashing simultaneously.
Indicator light 2 is on, indicating that the pump is blocked, for instance the shaft seal has seized up.
Cause	Remedy
The pump is blocked by impurities.	Check that the pump is not blocked. If the pump has been drained, it must be filled with liquid before startup. Start up the pump. The pump will remember the controller settings even if it is turned off. Contact Grundfos Service if the problem persists.
The shaft seal has seized up.	Check that the pump is not blocked. If the pump has been drained, it must be filled with liquid before startup. Start up the pump. The pump will remember the controller settings even if it is turned off. Contact Grundfos Service if the problem persists.

The pump is not running, and indicator light 4 is on

Grundfos Eye: Two opposite green indicator lights are permanently on.
Indicator light 4 is on, indicating dry running or water shortage.
Cause	Remedy
Dry running.	Check the water source, and prime the pump.

The pump is not running, and indicator light 3 is on

Grundfos Eye: Two opposite red indicator lights are flashing simultaneously.
Indicator light 3 is on, indicating leakage in the installation after the pump.
Cause	Remedy
The internal valve is defective or blocked in completely or partly open position.	Clean, repair or replace the internal valve.

The pump is not running, and indicator light 6 is on

Grundfos Eye: Two opposite green indicator lights are permanently on.
Indicator light 6 is on, indicating that the maximum runtime has been exceeded.
Cause	Remedy
The maximum runtime has been exceeded.	Check the installation for leakage and reset the alarm.

The pump is running, and indicator light 3 is on

Grundfos Eye: Two opposite green indicator lights are rotating.
Indicator light 3 is on, indicating leakage in the installation after the pump
Cause	Remedy
Leakage from the pipe system, or the external non-return valve is not properly closed due to impurities.	Check and repair the pipe system, or clean, repair or replace the external nonreturn valve.
Small continuous consumption.	Check the taps and reconsider the usage pattern (for example, ice machines and water evaporators for airconditioning).

The pump is running, and indicator light 7 is on

Grundfos Eye: Two opposite green indicator lights are rotating.
Indicator light 7 is on, indicating that the temperature is outside the range.
Cause	Remedy
The temperature of the pump and water is below 3°C.	Consider protecting the pump and the installation against frost.

Insufficient pump performance

System overpressure, and indicator light 5 is on

Grundfos Eye: Two opposite green indicator lights are rotating.
Indicator light 5 is on, indicating that the maximum pressure has been exceeded or the setpoint cannot be reached.
Cause	Remedy
The setpoint is set too high. The difference between the outlet pressure and the inlet pressure must not exceed 3.5 bar, 0.35 MPa (51 psi).	Reduce the pressure to a new setpoint (maximum 3.5 bar, 0.35 MPa (51 psi) + positive inlet pressure). Example: If the inlet pressure is 0.5 bar, 0.05 MPa (7 psi), the maximum outlet pressure is 4 bar, 0.4 MPa (58 psi).
The maximum pressure has been exceeded, the inlet pressure is higher than 6 bar, 0.6 MPa (87 psi).	Check the inlet conditions.
The maximum pressure has been exceeded. Equipment elsewhere in the system causes a high pressure at the pump, for example water heater or defective safety equipment.	Check the installation.

After a reset, the pump runs briefly, and indicator light 4 is on

Grundfos Eye: Two opposite green indicator lights are rotating.
Indicator light 4 is on, indicating dry running or water shortage.
Cause	Remedy
Dry running or water shortage.	Check the water source, and prime the pump.
The inlet pipe is blocked by impurities.	Clean the inlet pipe.
The foot or internal valve is blocked in closed position.	Clean, repair or replace the foot or internal valve.
There is a leakage in the inlet pipe.	Repair the inlet pipe.
Air in the inlet pipe or the pump.	Prime the inlet pipe and the pump. Check the inlet conditions of the pump.

After resetting, the pump immediately restarts, and indicator light 3 is on

Grundfos Eye: Two opposite green indicator lights are rotating.
Indicator light 3 is on, indicating leakage in the installation after the pump.
Cause	Remedy
The internal valve is defective or blocked in completely or partly open position.	Clean, repair or replace the internal valve.
The tank precharge pressure is not correct.	Adjust the tank precharge pressure to 70% of the required outlet pressure.
