2. 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 guard and the machine control, this safety component prevents dangerous machine functions

from occurring while the guard is open. A stop command is triggered if the guard is opened during the dangerous machine

function.

This means:

ÌStarting commands that cause a dangerous machine function must become active only when the guard is closed.

ÌOpening the guard triggers a stop command.

ÌClosing a guard must not cause automatic 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/MBG-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 guard and the machine control, this safety component prevents the guard from being opened

while a dangerous machine function is being performed.

This means:

ÌStarting commands that cause a dangerous machine function must become active only when the guard is closed and

locked.

ÌThe guard locking must not be released until the dangerous machine function has ended.

ÌClosing and locking a guard must not cause automatic starting of a dangerous machine function. A separate start com-

mand must be issued. For exceptions, refer to ENISO12100 or relevant C-standards.

The following applies to 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:

ÌENISO13849-1

ÌENISO12100

ÌIEC62061

Correct use includes observing the relevant requirements for installation and operation, particularly based on the following

standards:

ÌENISO13849 1

ÌENISO14119

ÌEN60204-1

The safety system MGB can be combined only with the intended modules in the MGB system family.

On the modication of system components, EUCHNER provides no warranty for function.

The customer is responsible for the safe overall function, especially for the safe integration into the CIPSafety® environment.

Important!

ÌThe user is responsible for the proper integration of the device into a safe overall system. For this

purpose, the overall system must be validated, e.g. in accordance with ENISO13849-2.

ÌCorrect use requires observing the permissible operating parameters (see chapter 18. Technical

data on page 30).

ÌIf a data sheet is included with the product, the information on the data sheet applies.

3. Description of the safety function

Devices from this series feature the following safety functions:

The following applies to MGB-L1 and MGB-L2:

Monitoring of guard locking and the position of the guard

(interlocking device with guard locking according to ENISO14119)

ÌSafety function (see chapter 6. Function on page 10):

- When guard locking is released, safety bit FI.UK (ÜK) = 0 (monitoring of the locking element).

- When the guard is open, safety bit FI.SK (SK) = 0.

- Guard locking can be activated only when the bolt tongue is located in the locking module (prevention of inadvertent

locking position (faulty closure protection)).

ÌSafety characteristics: category, Performance Level, PFHD(see chapter 18. Technical data on page 30).

Control of guard locking (safety bit FO.L)

ÌSafety function

If the device is used as guard locking for personnel protection, control of guard locking must be regarded as a safety

function. Guard locking is controlled via safety bit FO.L (see chapter 6.3. Guard locking for version MGB-L1 on page

11).

The safety level of guard locking control is determined by the device PFHDint. and by the external control (e.g. PFHDext. of

the standstill monitor).

4. Exclusion of liability and warranty

In case of failure to comply with the conditions for correct use stated above, or if the safety regulations are not followed,

or if any servicing is not performed as required, liability will be excluded and the warranty void.

5. General safety precautions

Safety switches fulll personnel protection functions. Incorrect installation or tampering can lead to fatal injuries to personnel.

Check the safe function of the safeguard particularly

Ìafter any setup work

Ìafter the replacement of an MGB component

Ìafter an extended period without use

Ìafter every fault

Independent of these checks, the safe function of the safeguard 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 fulll

a personnel protection function.

ÌSafety components must not be bypassed, turned away, removed or otherwise rendered ineffec-

tive. On this topic pay attention in particular to the measures for reducing the possibility of bypass-

ing according to ENISO14119:2013, section 7.

ÌThe switching operation is allowed to be triggered only by the intended handle module MGB-H…

that is positively fastened to the guard.

ÌPrevent bypassing by means of replacement actuators (only for multicode evaluation). For this

purpose, restrict access to actuators and to keys for releases, for example.

ÌMounting, electrical connection and setup only by authorized personnel possessing the following

knowledge:

- specialist knowledge in handling safety components

- knowledge about the applicable EMC regulations

- knowledge about the applicable regulations on operational 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. For this reason you should

archive a printed copy of the operating instructions. You can download the operating instructions from

www.euchner.com.

6. Function

6.1. Interlocking module MGB-L0.B-EI.

Together with a handle module, the interlocking module makes it possible to interlock movable guards. The combination

also serves as a mechanical door stop at the same time.

Important!

To operate the device as an interlocking device according to ENISO14119, the signals for door

position (safe bit FI.D) and bolt position (safe bit FI.B) must be polled in a logical AND operator.

This operator is already implemented in safety bit FI.SK.

As an alternative, you can also link the bits FI.D and FI.B individually in your control system.

The following switch-on condition applies to safety bit FI.SK (SK):

ÌGuard closed FI.D

ÌBolt tongue inserted into interlocking module FI.B

Also see chapter 16. System status table on page 28.

The interlocking module detects the position of the guard and the position of the bolt tongue.

The bolt tongue in the handle module is moved into and out of the interlocking module by actuating the door handle.

6.2. Locking module MGB-L1.B-EI. and MGB-L2.B-EI.

Together with a handle module, the locking module makes it possible to lock movable guards. The combination also serves

as a mechanical door stop at the same time.

Important!

To operate the device as a guard locking device for personnel protection according to ENISO14119,

the signals for door position (safe bit FI.D), bolt position (safe bit FI.B) and guard lock monitoring

(safe bit FI.L) must be polled in a logical AND operator. This operator is already implemented in

safety bit FI.UK.

As an alternative, you can also link the bits FI.D, FI.B and FI.L individually in your control system.

The following switch-on condition applies to safety bit FI.UK:

ÌGuard closed FI.D

ÌBolt tongue inserted into locking module FI.B

ÌLocking arm in locking position (guard lock monitoring) FI.L

Also see chapter 16. System status table on page 28.

The locking module detects the position of the guard and the position of the bolt tongue. The position of the locking arm

is also monitored.

The bolt tongue in the handle module is moved into and out of the locking module by actuating the door handle.

The locking arm locks the bolt tongue when the bolt tongue is fully inserted into the locking module. Depending on version,

this locking is by spring force or solenoid force.

Guard locking is controlled via safety bit FO.L. See chapter 6.3. Guard locking for version MGB-L1 on page 11.
