TIPS REGARDING OTHER REGULATIONS AND RISKS
• The procedural tips and excerpts from circuit diagrams given
throughout the technical documentation are to be applied mutatis
mutandi, i.e. to be checked for every application. BÖHNKE +
PARTNER does not accept any liability for their individual suitabil-
ity.
• To ascertain proper functions of the complete control system, you
must comply with the documentation of the manufacturers of third-
party components, which are supplied to you as well (e. g. opera-
tion instructions for the frequency inverter).
• The control system bp308 must exclusively be used for processing
information in elevator control systems.
• Control units, printed circuit boards, modules or other devices that
have been damaged on their transport to you must not be used or
commissioned.
• Printed circuit boards comprise electro-statically damageable ele-
ments. Therefore, before touching any electronic component make
sure that your own body has been discharged. You can do this by
touching a conductible earthed object (e. g. bare metal parts of the
control cabinet ).
4.1 EMC-Directives
All industrial, electronically controlled devices, such as, for example,
PCs, microprocessors, computers, SPSs, can be influenced by inter-
ference pulses if they have not been protected accordingly. These
interference pulses can be caused by external appliances, such as e.
g. voltage fluctuations in the feed-line or control pulses of the power
parts in the frequency inverter. BÖHNKE + PARTNER have taken all
usual measures while manufacturing the control unit. The installed
components are only slightly sensitive to interferences from their
environment.
ATTENTION!
• Follow the EMC instructions given by the manufacturer of the fre-
quency inverter at all times !
• Should you have any question concerning the EMC Directive
please ask our service team .
• Please also pay attention to the tips concerning interference sup-
pressing measures given in this manual.
