On safety
This chapter deals with your own safety and the safety of the equipment operators.
➢ Please read this chapter carefully before working with the Standstill Monitor MOC3ZA or
with the machine protected by the MOC3ZA.
2.1
Qualified safety personnel
The Standstill Monitor MOC3ZA must be mounted and commissioned only by qualified
safety personnel. Qualified safety personnel are defined as persons who ...
have undergone the appropriate technical training
and
have been instructed by the responsible machine owner in the operation of the machine
and the current valid safety guidelines
and
have access to the operating instructions of the MOC3ZA and have read and
familiarized themselves with them
and
are sufficiently familiar with the applicable official health and safety regulations,
directives and generally recognized engineering practice (e.g. DIN standards, VDE
stipulations, engineering regulations from other EU member states) that they can
assess the work safety aspects of the power-driven equipment.
2.2
Applications of the device
The Standstill Monitor MOC3ZA is used for the sensor-less monitoring of electric motors for
standstill. It makes possible the safe detection of the standstill of electric motors, e.g. to
enable the unlocking of guards on machine tools or to activate retaining brakes. The
Standstill Monitor can be used as per the following standards:
IEC 61 5 08 and IEC 61 5 11 up to SIL3
EN 62061 up to SILCL3
EN ISO 13849-1 up to category 4
EN ISO 13849-1 up to Performance Level e
The degree of safety actually attained depends on the external circuit and the design of
the wiring.
