Remedy:
- for a pump, check the medium being pumped, and if required, provide the medium.
- for a fan, check the belt, and if required, replace.
- if necessary, increase the detection torque threshold (p2191).
A07893
Drive: Load monitoring pump leakage
Reaction:
NONE
Acknowledge:
NONE
Cause:
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
Remedy:
- remove the leak in the pump circuit.
- for a nuisance trip, reduce the torque thresholds of the leakage characteristic (p2186, p2188, p2190).
F07894
Drive: Load monitoring pump/fan blocked
Reaction:
OFF1 (NONE, OFF2, OFF3)
Acknowledge:
IMMEDIATELY
Cause:
The load monitoring is configured for a pump or fan (p2193 = 4, 5).
The monitoring function detects when the pump/fan is blocked.
It is possible that the blocking torque threshold (p2168) is set too low (e.g. heavy duty starting).
See also: p2165, p2168, p2181, p2193
Remedy:
- check whether the pump/fan is blocked, and if blocked, then resolve the problem.
- check that the fan can freely move, and if necessary, resolve the problem.
- adapt the parameterization corresponding to the load (p2165, p2168)..
F07895
Drive: Load monitoring pump/fan no load condition
Reaction:
OFF1 (NONE, OFF2, OFF3)
Acknowledge:
IMMEDIATELY
Cause:
The load monitoring is configured for a pump or fan (p2193 = 4, 5).
The monitoring function detects when the pump/fan is operating under no load conditions.
The pump is running in the dry state (no medium to be pumped) – or the fan has a broken belt.
It is possible that the detection torque threshold is too low (p2191).
See also: p2181 (Load monitoring response), p2191 (Load monitoring torque threshold no load), p2193 (Load monitoring
configuration)
Remedy:
- for a pump, check the medium being pumped, and if required, provide the medium.
- for a fan, check the belt, and if required, replace.
- if necessary, increase the detection torque threshold (p2191).
F07896
Drive: Load monitoring pump leakage
Reaction:
OFF1 (NONE, OFF2, OFF3)
Acknowledge:
IMMEDIATELY
Cause:
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
Remedy:
- remove the leak in the pump circuit.
- for a nuisance trip, reduce the torque thresholds of the leakage characteristic (p2186, p2188, p2190).
