1.10 Standards and directives
Hoists in which SLE control equipment is installed are subject to the following directives
• Machinery Directive 2006/42/EC and
• EMC Directive 2014/30/EU
The SLE 3 was built in accordance with the following valid European standards and
regulations:
• IEC / EN 60204-32 – "Safety of machinery – Electrical equipment of machines – Part
32: Requirements for hoisting machines"
• EN 14492-2 – "Cranes – Power driven winches and hoists – Part 2: Power driven
hoists"
• ISO / EN 13849-1 – "Safety of machinery – Safety-related parts of control systems –
Part 1: General principles for design"
The SLE 3
• may only be used for control of a manually controlled single hoist from the manufac-
turer.
• is intended for industrial installations and may only be used in accordance with the
information in the technical documentation and the information on the rating plate.
• contains a safety-related overload cut-off that can, with due regard to the corre-
sponding standards specifically applicable to the machines / systems, be used for
the above-mentioned machines and systems in conjunction with a load sensor (see
chapter "Load sensor" for specification) up to category 2, PL d, according to
EN 13849-1.
• is a configurable device that only performs the safety functions after setting of the
safety-related parameter "Overload cut-off point"; this parameter may only be
changed by a competent person.
• is used in the control equipment as a central safety device for overload protection.
• is used in the hoist control equipment to actuate the motor.
• monitors the temperature of the motor by means of a thermistor (PTC).
• The circuit diagrams and schematic circuit diagrams delivered with the hoist must be
observed and implemented in control equipment built by the customer.
• When integrating the control equipment delivered by the manufacturer in a general
control system or higher-level PLC, the product standards for hoists and the tech-
nical specifications regarding the functionality, signal sequence and timing of the de-
vice must be followed.
• The plant manufacturer is responsible for the overall system.
All faults and warnings that are indicated must be corrected immediately. If this is not
possible, the device, and therefore also the hoist it controls, must be taken out of service
until the fault has been corrected.
Any other use of the device or changes to the device itself, also during assembly
and installation, will lead to the loss of all warranty claims against the manufactur-
er.
