motor running in lifting operation.
04.93
2. When the hoist is at a standstill and during lowe-
ring, the last value measured is displayed.
e.g.
04.93
3. The value indicated is updated when the hoist is rai-

1. If the hoist is shut down because the maximum limit
of the inching counter is exceeded, the number of
inching operations completed is displayed.
e.g.
- - 17
2. In the case of mutual monitoring of two hoists, this
symbol appears on the display in the event of a ho-
ist failure as long as the up or down button on the
pendant control is pressed:
– – H2
3. If a rotor power input of <10Watt is measured with
the motor in operation, the hoist is shut down and
U_I
