Siemens A07893

Brand: SiemensModel: SINAMICS G120 CU250S2Error code: A07893

What the Fault Means

Alarm: Drive: Load monitoring pump leakage

Likely causes

  • The load monitoring is configured for a pump (p2193 = 4)
  • The monitoring function detects a leak in the pump circuit
  • In this case, the pump requires a torque that is lower than in normal operation to pump the reduced quantity
  • See also: p2181, p2182, p2183, p2184, p2186, p2188, p2190, p2193

Solution and Safe First Checks

  1. remove the leak in the pump circuit.
  2. for a nuisance trip, reduce the torque thresholds of the leakage characteristic (p2186, p2188, p2190).

Safety: do not work inside the panel without isolating the power; if unsure, consult a qualified technician.
