3.1.5 Overload protection n-times reset
EntelliPro ES has an n-times automatic reset function, which allows a defined number of automatic reset operations.
The reset count will be automatically cleared when one hour elapses from the last overload trip.
The n-times can be set in the WinESG parameterization/alarm panel shown in the illustration below, or Modbus
function code 6 register 45.
Figure 3-11 shows an example of the auto-reset count operation. In this particular example the auto reset is set
to 2.

Figure 3-11 EntelliPro Auto-reset operation
For an ATEX configured device, the Auto-Reset parameter can be set to four different values: 0, 1, 2, and 3.
For a non-ATEX configured device, the values allowed are from 0 to 65535. However any value greater than 3 indicates
that Auto-Reset is always allowed.
When the auto-reset parameter is set to 0, the auto-reset is disabled and a manual reset is required after an overload
trip.
