3 Product and functional description
3.1 Description
The SLE 3 is an electronic control unit for hoists. The device can be used to control pole-
changing or frequency-controlled drives. It contains a safety-related overload cut-off for
hoists in conjunction with a load sensor. It is a configurable system that only performs the
overload protection function after parameterisation and storage of the safety-relevant
parameter (overload cut-off point) in that the lifting movement is switched off safely.
The device also carries out other, non-safety related control and monitoring functions:
•
Temperature monitoring for hoist and travel motors
•
Display of system states via signalling relays
•
Control of the lifting movements with motor management
•
Counting of operating time
3.2 Load sensor
ATTENTION
The SLE 3 processes signals from passive DMS load sensors (see technical data).
The load sensor is a safety-relevant component. Due to this, only load sensors approved
by the manufacturer may be used. In the event of a defective load sensor, a sensor of
the same type must always be ordered and fitted. The load sensors are specified by the
manufacturer appropriately for the respective hoist and load and assigned internally.
Pay attention to the chapter "Device and sensor replacement" when replacing a load
sensor.
Fitting an unapproved load sensor will cancel the warranty and approval of the
device!
