Follow all instructions and warnings for inspecting, maintaining and operating this product.
The use of any hoist presents some risk of personal injury or property damage. That risk is greatly increased if proper
instructions and warnings are not followed. Before using this hoist, each operator should become thoroughly familiar with all
warnings, instructions and recommendations in this manual. Retain this manual for future reference and use.
Forward this manual to operator. Failure to operate equipment as directed in manual may cause injury.

Page 5: General Information
General information on these operating instructions These operating instructions serve as safety manual in the sense of the safety stand- ards for functional safety of the SLE 3 electronic control unit for the manufacturer's hoists. They are aimed at the manufacturers, operators, commissioning engineers and service personnel of hoists. -
Page 6: Symbols
General information Symbols The safety instructions in the manual are subdivided according to the severity of the hazard and the likelihood of it occurring. The measures described to avoid the hazards must be followed. DANGER This symbol warns of a direct danger to the health and life of people. Disregarding these warnings will lead to severe injuries, possibly also death. -

Commissioning / Operation / Documentation WARNING The SLE 3 only achieves its safety function when it has been programmed accordingly. The commissioning of a hoist must be documented. This documentation must also contain the overload cut-off point. The signature of the qualified person and the operator is needed after commissioning (section “Commissioning and testing”). -

WARNING Failure of one of the downstream power elements • Downstream power elements are not monitored by the SLE 3. • Failure is to be prevented by the designer of the control equipment by suitable choice. • In the event of failure the operator must have the power element replaced immediate- ly by a competent person. -
Page 11: Product And Functional Description
Product and functional description 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. -

• If the signal voltage between the connections IN+ and IN- exceeds the cut-off thresh- old setting while the outputs K↓ and K↓↓ are active or when stationary, the SLE 3 detects "overload" after a time of 800 ms and blocks the outputs K↑ and K↑↑ until no overload is detected any more. -
Page 15: Sensor Errors
Actuation of S↕↕ is only recognised if the corresponding direction S↑ or S↓ is active at the same time. If S↑ or S↓ is actuated from idle state, the SLE 3 switches the respective safety output K↑ or K↓ after a maximum delay time of 300 ms. -
Page 16: Relay Outputs
Product and functional description 3.7.2 Relay outputs The relay outputs switch the voltage connected to L↑↓ through to the downstream actuators (e.g. contactor). The control voltage at L↑↓ must correspond to the power supply at L.

The travel motor thermistor (PTC) is connected to input 2 (if two or more travel motors, for all). When a travel motor thermistor responds, the SLE 3 switches the relay outputs left/right off and reports this via the device LED (as warning) that the travel motor(s) can no longer be actuated. -

SLE 3 and that the components and units in- volved in the safety function work perfectly in interaction with the SLE 3. The type of use / attachment of the SLE 3 and the follow-up of the plant must also be tested. Acceptance test: overload cut-off: Lifting of a test load of 110 % of the maximum lifting capacity. -
Page 22: Change To The Cut-Off Point
