Normal Operation
Temperatures
If the surface temperature of the winch exceeds 90°C (194°F) there is a risk of
damaging the winch.
Duty cycle
The winch should not be operated at a duty cycle higher than 30% for longer periods of
time.
The duty cycle is the fraction of a period where the motor is active. The duty cycle is
commonly expressed as a percentage or a ratio. It can be described as the period of
time it takes for a system to complete an on-and-off cycle.
Thus, a 10% duty cycle means the system is on 10% of the time and off 90% of the time.
The "on time" for a 10% duty cycle is normally connected to a cycle length in minutes.
E.g. a max duty cycle of 30% (10 min ON / 23 min OFF), means that the motor may not
be active more than 10 minutes every 33 minutes or after 10 minute of ON the motor
must be OFF for 23 minutes.
Lifting speeds and weight
The load of the winch impacts the minimum speed it can operate at. At heavy loads
the minimum speed up must be increased to a point where the winch can still move.
If a light load is used with high minimum speeds the winch might have problems with
finding its position. Lower the minimum speeds if this is a problem.
The minimum speed can be adjusted from the menu.
Wire fleet
Because of the way the winch rolls up the wire, the place where the wire comes out of
the winch changes depending on how much wire has been rolled out. The wire moves
83mm sideways from the hard TOP to BOTTOM limit during the movement.
