The current drawn by the pump motor exceeded the maximum limit.

 

Blockages in the flow path are usually detected by the pressure sensor in the

 

damper, which result in the pump switching off when the upper pressure

 

limit is exceeded. If a blockage occurs before the damper, the pressure

 

increase cannot be detected by the pressure sensor and the quaternary pump

 

will continue to pump. As pressure increases, the pump drive draws more

 

current. When the current reaches the maximum limit, the quaternary pump

 

is switched off, and the error message is generated.

Probable Causes

• Flow path blockage in front of the damper.

 

• Blocked active inlet valve.

 

• Blocked outlet ball valve.

 

• High friction (partial mechanical blockage) in the pump drive assembly.

 

• Defective pump drive assembly.

 

• Defective LPM board.

Suggested Actions

❏ Ensure the capillaries and frits between the pump head and damper inlet

 

are free from blockage.

 

❏ Exchange the active inlet valve.

 

❏ Exchange the outlet ball valve.

 

❏ Remove the pump-head assembly. Ensure there is no mechanical blockage

 

of the pump-head assembly or pump drive assembly.

 

❏ Exchange the pump drive assembly.

 

❏ Exchange the LPM board.
