Page 3: General Information
General information General information General information on operating instructions These operating instructions form an integral part of the SLE22 electronic control device for the manufacturer's hoists. It is addressed to hoist manufacturers, users, operators, commissioning engineers and service personnel. It must be available to the machinery manufacturer's or operator's technical personnel during the whole period of use for erection, electrical installation, configuration, commis- sioning, maintenance and diagnosis, and be observed by them. -
Page 4: Symbols
General information Symbols In these instructions, the safety notices are classified according to the severity of the danger and the probability of its occurrence. The procedures described for avoiding danger must be followed without fail. DANGER This symbol gives warning of an imminent danger to health and life. Ignoring these warning notices will lead to severe injuries, possibly resulting in death. -
Page 5: Target Group
General information Target group NOTICE All installation work and elimination of faults must be carried out by a skilled electri- cian, commissioning and maintenance by a qualified person. The following must be observed • EN 60204-1 and 32 • DIN VDE 0100 •... -
Page 6: Commissioning / Operation / Documentation
Commissioning / operation / documentation NOTICE The SLE22 does not fulfil its safety function until it has been programmed accordingly. Commissioning a hoist must be documented. This documentation must also include the overload cut-off point. It must be signed by the qualified person and the user after commissioning (Chapter 5: Commissioning and testing). -
Page 7: General Safety Instructions
General safety instructions General safety instructions DANGER Observe the safety information without fail: • National and international directives and regulations must be observed for erection, commissioning, operation and periodic tests, in particular the Machinery Directive 2006/42/EC, the directive for the use of work equipment 89/655/EEC, safety regula- tions and relevant national safety regulations. - Page 8 DANGER Failure of one of the downstream power devices: • Downstream power devices are not monitored by the SLE22. • Failure must be prevented by the designer of the control selecting appropriate devices • If a device fails the user must have it replaced immediately by a qualified person.

Page 9: General Description, Function
General description, function Description The SLE22 is an electronic control device for hoists. The device can be used to control pole-changing or frequency-controlled drives. It comprises a safety-oriented overload cut- off for hoists in conjunction with a load sensor (see point 3.2.) It is a configurable system that performs the safety function only after parameterizing and saving the safety-relevant parameter overload cut-off point, reliably disconnecting the hoist motion. -

Outputs K↓ and K↓↓ can be switched after an overload has been detected! 3.6.2 Sensor errors The SLE22 constantly monitors and compares the values of sensor channels 1 and 2. The following three types of sensor error are detected: Differential error if the difference between the sensor currents is >... -

The activation of S↕↕ is only detected if the related direction S↑ or S↓ is also active at the same time. If S↑ or S↓ are activated from idle state, the SLE22 switches the related safety output K↑ or K↓ after a maximum delay time of 300 ms. - Page 13 General description, function If the direction of activation is reversed, the hoist is stopped and the relevant safety output is activated after cut-off time tr has expired. 10.2013...

SLE22 and that correct functioning of the components or units affecting the safety function in interaction with the SLE22 is ensured. In addition, the type of use / mounting of the SLE22 and the braking path of the system are to be tested. -
Page 19: Crane Test
Commissioning and testing Crane test DANGER When commissioning a hoist a so-called crane test must be performed in accordance with its original operating instructions. To enable this, the "Crane test" function can be acti- vated, raising the overload cut-off point. The "Crane test"... -
Page 20: Documenting Alterations Of Cut-Off Point
Commissioning and testing Documenting alterations of cut-off point DANGER After testing the new cut-off point, it must be documented, confirmed and signed in the lid of the case, in the following table and in the crane logbook. Any undocumented alteration of the cut-off point leads to an immediate loss of warranty and is grossly negligent. -
