Safety Information and Maintenance (Part of the
Operating Instructions for Safety System MGB-L.B-EI.-... (Ethernet/IP))
Scope
This safety information is part of the operating
instructions for the safety system MGB. It applies
to the following MGB systems:
Series
System family
MGB
...‑EI...
MGB‑H...
Correct use
The following applies to MGB-L0:
The system comprises at least one interlocking
module MGB‑L0‑... and one handle module MGB‑H...
The safety system MGB is an interlocking device
without guard locking (type 4). Devices with unicode
evaluation possess a high coding level, devices with
multicode evaluation possess a low coding level.
In combination with a movable safety guard and
the machine control, this safety component pre‑
vents dangerous machine functions from occurring
while the safety guard is open. A stop command is
triggered if the safety guard is opened during the
dangerous machine function.
This means:
Starting commands that cause a dangerous ma‑
f
chine function must become active only when the
safety guard is closed.
Opening the safety guard triggers a stop com‑
f
mand.
Closing a safety guard must not cause automatic
f
starting of a dangerous machine function. A
separate start command must be issued. For
exceptions, refer to EN ISO 12100 or relevant
C‑standards.
The following applies to MGB-L1/MGB-L2:
The system comprises at least one locking module
MGB‑L1‑.../MGB‑L2‑... and one handle module
MGB‑H...
The safety system MGB is an interlocking device
with guard locking (type 4). Devices with unicode
evaluation possess a high coding level, devices with
multicode evaluation possess a low coding level.
In combination with a movable safety guard and the
machine control, this safety component prevents the
safety guard from being opened while a dangerous
machine function is being performed.
This means:
Starting commands that cause a dangerous ma‑
f
chine function must become active only when the
safety guard is closed and locked.
The guard locking device must not be unlocked
f
until the dangerous machine function has ended.
Closing and locking a safety guard must not cause
f
automatic starting of a dangerous machine func‑
tion. A separate start command must be issued.
For exceptions, refer to EN ISO 12100 or relevant
C‑standards.
For MGB-L0 /MGB-L1 / MGB-L2
The interlocking module MGB‑L0B‑EI.‑... and the
locking module MGB‑L1B‑EI.‑.../MGB‑L2B‑EI.‑... are
operated as IO devices under Ethernet/IP.
Before the device is used, a risk assessment must
be performed on the machine, e.g. in accordance
with the following standards:
EN ISO 13849‑1, Safety of machinery – Safety‑re‑
f
lated parts of control systems – Part 1: General
principles for design
EN ISO 12100, Safety of machinery – Basic
f
concepts – General principles for design – Risk
assessment and risk reduction
IEC 62061, Safety of machinery – Functional
f
safety of safety‑related electrical, electronic and
programmable electronic control systems
Correct use includes observing the relevant require‑
ments for installation and operation, particularly
based on the following standards:
EN ISO 13849‑1, Safety of machinery – Safety‑re‑
f
lated parts of control systems – Part 1: General
Product version
principles for design
EN ISO 14119 (supersedes EN 1088), Safety of
from V1.0.0
f
machinery – Interlocking devices associated with
from V2.0.0
guards – Principles for design and selection
EN 60204‑1, Safety of machinery – Electrical
f
equipment of machines – Part 1: General re‑
quirements
The safety system MGB can only be combined with
the intended modules in the MGB system family.
On the modification of system components, EUCH‑
NER provides no warranty for function.
The customer is responsible for the safe overall
function, especially for the safe integration into the
CIP‑Safety environment.
Exclusion of liability and warranty
In case of failure to comply with the conditions for
correct use stated above, or if the safety instruc‑
tions are not followed, or if any servicing is not
performed as required, liability will be excluded and
the warranty void.
General safety instructions
Safety switches fulfill personal protection functions.
Incorrect installation or tampering can lead to fatal
injuries to personnel.
Check the safe function of the safety guard particularly
after any setup work
f
after the replacement of an MGB component
f
after an extended period without use
f
after every fault
f
after any change to the DIP switch setting
f
Independent of these checks, the safe function of the
safety guard should be checked at suitable intervals
as part of the maintenance schedule.
WARNING
Danger to life due to improper installation or due
to bypassing (tampering). Safety components
perform a personal protection function.
Safety components must not be bypassed,
f
turned away, removed or otherwise rendered
ineffective. On this topic pay attention in partic‑
ular to the measures for reducing the possibility
of bypassing according to EN ISO 14119:2013,
section 7.
The switching operation is only allowed to be trig‑
f
gered by the intended handle module MGB‑H...
that is positively fastened to the safety guard.
Prevent bypassing by means of replacement
f
actuators (only for multicode evaluation). For this
purpose, restrict access to actuators and to keys
for releases, for example.
Mounting, electrical connection and setup only
f
by authorized personnel possessing the following
knowledge:
‑ specialist knowledge in handling safety com‑
ponents
‑ knowledge about the applicable EMC regu‑
lations
‑ knowledge about the applicable regulations on
occupational safety and accident prevention.
Important!
Prior to use, read the operating instructions and
keep these in a safe place. Ensure the operating
instructions are always available during mounting,
setup and servicing. EUCHNER cannot provide any
warranty in relation to the readability of the CD for
the storage period required. For this reason you
should archive a printed copy of the operating
instructions. You can download the operating
instructions from www.euchner.de.
Operating instructions on CD/DVD
Each device is supplied with operating instructions
