PNOZ s3. For calculation of the whole safety function "enabling" the control
relay and all subsequent components have to be considered.
6.4 Foreseeable Misuse of Enabling control device
Foreseeable misuse means the not allowed fixing of the enabling control de-
vice in the enabling position. The foreseeable misuse of the enabling control
device must be restricted.
The following measures causing the stop of the machine in the manual mode
are recommended:
●
Inquiry of the enabling control device when turning on the machine/plant
and inquiry of the enabling control device when changing the operating
mode from automatic to manual (The enabling control device must not be
in the enabling position.).
●
The enabling control device must be released within a defined period and
pushed into the enabling position again. The length of the period must be
defined according to the activity.
WARNING!
●
The enabling control device is only suitable as safety function if the oper-
ator activating the enabling control device recognizes the dangerous sit-
uation in time so that he can immediately take the necessary measures to
avoid such situations. As additional measure reduced speed of the move-
ment can be necessary. The allowed speed must be determined by means
of a risk assessment.
●
The enabling control device is only used to enable commands for perform-
ing dangerous movements. The commands themselves must be activated
by a separate operating element (key on handheld terminal).
●
Only the person who operates the enabling control device is allowed to work
in the dangerous area.
●
For further informations regarding the enabling control device please pay
attention to chapter "Machinery Safety".
6.5 Ethernet
The standard version of the KeTop is equipped with an Ethernet interface, the
signals are transferred by shielded lines in the connection cable.
The following interface parameters are defined and cannot be changed:
●
10 MBit/s
●
UDP and TCP/IP protocol
