Motor-Drive Power

Error ID: 2041, 2042
Motor- Drive Power: Pump channel A
B: Motor- Drive Power: Pump channel B
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
module will continue to pump. As pressure increases, the pump drive
draws more current. When the current reaches the maximum limit, the
module is switched off, and the error message is generated.

Flow path blockage in front of the damper.
Blocked active inlet valve.
Blocked outlet valve.
High friction (partial mechanical blockage)
in the pump drive assembly.
Defective pump drive assembly.
Defective main board.
Restriction capillary blocked at pre-mixing
union.
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 valve.
Remove the pump-head assembly. Ensure there
is no mechanical blockage of the pump-head
assembly or pump drive assembly.
