Grain storage­ ventilation system

The drive motor of a mixing feed screw in a grain storage facility is to be protected against incorrect phase sequences when it is connected to the power supply.

When the mixing feed screw is connected to the outlet, an incorrect phase sequence is recognised immediately, and no power is supplied to the screw. This effectively prevents the drive motor against damage.

– Prevention of possible motor damage through the immediate recognition of incorrect voltages
– Highly compact module requires little space, width of just 17.5 mm important (mobile system)
– Motor protection
– Minimisation and prevention of downtime
