6.3 Set motor protection circuit
Set motor protection circuit
1. Set motor protection circuit to approximately 0.85 to 0.9 times the motor current (I
M
).
✓
When operating normally, the motor protection circuit will not trip prematurely.
✓
When the pressure-limiting valve triggers, the period until shutdown does not become long enough
for the hydraulic uid’s temperature to exceed its permissible maximum.
2. Run a test run to check the motor protection circuit’s settings.
Additional safety precautions against malfunctions are the temperature switches, level switches
and pressure switches. These are optionally available for the hydraulic power pack.
