▪
Be constructed and fitted in such a way that the following faults do not lead to
damage:
– short circuits
– mechanical impacts
– power supply failures or surges
– electromagnetic fields
– earth connections
The electrical equipment and control must not put the protective devices of the
drive system and the motor protection (e.g. PTC resistor, bimetal switch, frequen-
cy inverter current limit) out of operation.
When the power supply fails or surges, the control must prevent the G-BH1 | G-
BH9 from remaining in operation or starting up.
Protective devices and switches must fulfil the failure safety conditions.
Overcurrent protection
Separator for the electrical energy supply
A separator for the electrical energy supply must be:
▪
Provided according to IEC 60204-1, 5.3 and 5.5.
▪
Clearly and visibly labelled.
Controls
Controls and instruments must be constructed and arranged in such a way that:
▪
They are easily visible and accessible, and can also be operated without ex-
cessive effort.
▪
The operator understands the functions.
▪
Operating faults are prevented.
A control system must correspond to ISO 12100, 4.11; IEC 60204-1, 9.4 and ISO
13849-1.
When the power supply fails, a "system with oriented failure mode" according to
ISO 12100, 6.2.12.3 must be used.
Start and stop devices must be clearly marked in accordance with ISO 13850 and
IEC 60417.
EMERGENCY OFF function
An EMERGENCY OFF function must be provided when a dangerous situation can
occur that must be rectified manually (see ISO 12100, 6.3.5.2)
▪
Implement the EMERGENCY off function according to EN 418 and EN 50099.
▪
Implement a manual EMERGENCY OFF function according to ISO 13849-1, 5
(in particular 5.2.1).
▪
The stop category and colour of the EMERGENCY OFF function must corre-
spond to ISO 13850.
▪
If a risk assessment determines that the normal switch can fulfil the EMER-
GENCY OFF function, this should be labelled accordingly.
After an EMERGENCY OFF, start-up is only possible via a deliberate, manually-
triggered procedure.
Manual reset
A manual reset after a stop command must correspond to ISO 13849-1, 5.5.2 and
IEC 60204-1, 9.2.5.3 and 9.2.5.4.
