1.7.1 Which devices have to comply with the new machine directive?
This rule is valid for KEBA and its customers:
Depending on the date the product has been put into circulation the new ma-
chine directive has to be applied or not. If the KeTop will be delivered in its end
use after 2009-12-29, it will be put into circulation newly - even if it has been
sold by KEBA at an earlier date.
●
Devices complying with the old MD and that will be sent to KEBA for repair,
can be repaired and delivered in compliance with the old MD.
●
Customer sends old device for repair and will receive the same or another,
equal device.
●
Devices complying with the new MD and that will be sent to KEBA for repair,
must be repaired and delivered in compliance with the new MD.
1.7.2 Quantitative safety relevant specifications for emergency stop-button
and enabling control device
●
Emergency stop-button:
KEBA specifies a B
10d
-value. Other values (e.g. SIL, PL, Category) can-
not be specified by KEBA.
Explanation: KEBA solely delivers the control element, but no evaluation
of the element. The customer has to connect the emergency stop to his
application on his own. Depending on the connection of the emergency
stop to the machine the SIL- or category and PL-value can be determined.
●
Enabling control device:
KEBA specifies category and PL in accordance to EN ISO 13849-1. De-
rived from this value KEBA also specifies a PFH- and MTTF
d
-value in
accordance to EN ISO 13849-1. SIL (in accordance to EN 62061 or
EN 61508) cannot be specified by KEBA.
Explanation: The enabling control devices has been evaluated in accord-
ance to EN ISO 13849-1. A B
10d
-value is not available for the enabling
control device, as this device consists of the mechanic element and the
electronic evaluation. This means that KEBA specifies MTTF
d
- and DC-
values (and derived from these values also Category, PL and PFH) for the
enabling control device as a whole (starting from the pushbutton up to the
clamps within the junction box).
1.7.3 Relationship between Performance Level and Safety Integrity Level
When evaluating safety functions by IEC EN 62601 the PL can be transformed
into SIL by following the equivalence table of EN ISO 13849-1.
Table 4 (EN ISO 13849-1) - Relationship between Performance Level (PL) and
Safety Integrity Level (SIL)
Performance Level (PL) by
EN ISO 13849-1
Safety Integrity Level (SIL) by
IEC 61508-1
