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 feature a low coding level.
In combination with a movable safety guard and the machine control, this safety component prevents 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:

Ì Starting commands that cause a dangerous machine function must become active only when the safety guard is closed.
Ì Opening the safety guard triggers a stop command.
Ì Closing a safety 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…

high coding level; devices with multicode evaluation feature 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:

Ì Starting commands that cause a dangerous machine function must become active only when the safety guard is closed

and locked.

Ì The guard locking device must not be unlocked until the dangerous machine function has ended.
Ì Closing and locking a safety 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.

For MGB-L0 /MGB-L1 / MGB-L2

4. Exclusion of liability and warranty

In case of failure to comply with the conditions for correct use stated above, or if the safety instructions are not followed,
or if any servicing is not performed as required, liability will be excluded and the warranty void.

5. General safety instructions

Safety switches fulll personal protection functions. Incorrect installation or tampering can lead to fatal injuries to personnel.
Check the safe function of the safety guard particularly

Ì after any setup work
Ì after the replacement of an MGB component
Ì after an extended period without use
Ì after every fault
Ì after any change to the DIP switch setting

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.

Ì Safety 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 bypass­ing according to ENISO14119:2013, section 7.

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

that is positively fastened to the safety guard.

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

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

Ì Mounting, 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 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.

6. Function

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

Together with a handle module, the interlocking module makes it possible to interlock moving safety guards. The combina­tion also serves as a mechanical door stop at the same time.

The following switch-on condition applies to safety bit SI 9 (SK):

Ì Safety guard closed (T)
Ì Bolt tongue inserted into interlocking module (R)

See also chapter 16. System status table on page 33 and chapter 13.8. PROFIsafe data bytes (data block for safe
functions) on page 30.

The interlocking module detects the position of the safety 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-PN. and MGB-L2.B-PN.

Together with a handle module, the locking module makes it possible to lock moving safety guards. The combination also
serves as a mechanical door stop at the same time.

Important!

To operate the device as a guard lock for personnel protection according to ENISO14119, the sig­nals for door position (T=PROFIsafe bit SI 3), bolt position (R= PROFIsafe bit SI 4) and guard lock
monitoring (Z= PROFIsafe bit SI 5) must be polled in a logical AND operator. This operator is already
implemented in the PROFIsafe data block (ÜK=safety bit SI 10).

As an alternative, you can also link the bits SI 3 to SI 5 individually in your control system.

The following switch-on condition applies to safety bit SI 10 (ÜK):

Ì Safety guard closed (T)
Ì Bolt tongue inserted into locking module (R)
Ì Locking arm in locking position (guard lock monitoring) (Z)

See also chapter 16. System status table on page 33 and chapter 13.8. PROFIsafe data bytes (data block for safe func-
tions) on page 30.

The locking module detects the position of the safety 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.
When the bolt tongue is fully inserted in the locking module, the locking arm locks the bolt tongue in this position. Depending

on the version, this locking is by spring force or solenoid force.

6.3. Guard locking for version MGB-L1

(guard locking actuated by spring force and released by energy ON)

Activating guard locking: close safety guard; no voltage at the solenoid (safety bit SO 1=0).
Releasing guard locking: apply voltage to the solenoid (safety bit SO 1=1).

The spring-operated guard locking functions in accordance with the closed-circuit current principle. If voltage is interrupted
at the solenoid, guard locking remains active and the safety guard cannot be opened directly.

Important!

If the safety guard is open when the power supply is interrupted and the guard is then closed, guard
locking is activated. This can lead to persons being locked in unintentionally.

As long as the locking arm is closed, the bolt tongue cannot be pulled out of the locking module and the safety guard is locked.
When voltage is applied to the locking solenoid, the locking arm is opened and bolt tongue is released. The safety guard

can be opened.

6.4. Guard locking for version MGB-L2

(guard locking actuated by energy ON and released by spring force)

Important!

Use as guard locking for personnel protection is possible only in special cases, after strict assessment
of the accident risk (see ENISO14119:2013, section 5.7.1)!

Activating guard locking: apply voltage to the solenoid (safety bit SO 1=1).

Releasing guard locking: disconnect voltage from the solenoid (safety bit SO 1=0).

The magnetically actuated guard locking operates in accordance with the open-circuit current principle. If voltage is inter­rupted at the solenoid, guard locking is released and the safety guard can be opened directly!

The safety guard can be opened as long as no voltage is applied to the guard locking solenoid.
When voltage is present at the guard locking solenoid, the the locking arm is held in locked position and the safety guard

is locked.

6.5. Control of the guard locking

From MGB version V2.36.4, the factory ensures that control is possible only from the safe control area.
By changing the parameters in the conguration tool of your control system, it can be set whether bit O 16 (in the safe

data block for the MGB locking module) is evaluated as well.

Important!
The following applies to MGB-L2:

Control of the guard locking via the safe control area does not provide increased safety, as the device­internal control of the guard locking is only of single-channel design.

Important!

The following functions depend on the MGB version, the version of the GSD le and the settings made
there.
Compare the specied versions with those on your device and your GSD le. The version number of
your MGB can be found on the type plate (format: VX.XX.X).

7.7. Mechanical release

In the event of service, the guard locking can be released with the mechanical release irrespective of the state of the sole­noid (see Figure 6).

Important!

Ì The system enters into a latching fault when the mechanical release is actuated. See System sta-

tus table, signal sequence incorrect status (DIA red, Lock ashes 1 time).

Ì The system might not enter into a latching fault if the mechanical release is actuated very slowly.

Important!

Ì The mechanical release is not a safety function.
Ì The machine manufacturer must select and use a suitable release (escape release, emergency

unlocking, etc.) for a specic application. A risk assessment is required for this purpose. It may be
necessary to take specications from a product standard into account.

Ì The correct function must be checked at regular intervals.
Ì Loss of the release function due to mounting errors or damage during mounting. Check the re-

lease function every time after mounting.

Ì Please observe the notes on any enclosed data sheets.

The locking screw must be screwed back in and sealed (for example with sealing lacquer) after assembly and after every
use of the mechanical release. Tightening torque 0.5 Nm.

1. Undo locking screw.

2. Lift locking arm using a screwdriver and actuate door handle.

7.9. Escape release (optional)

The escape release is used to open a locked safety guard from the inside without tools.
The system enters into a latching fault when the escape release is actuated.

See chapter 16. System status table on page 33, signal sequence incorrect status (DIA red, Lock ashes 1 time).
The system might not enter into a latching fault if the escape release is actuated very slowly.

Important!

Ì It must be possible to operate the escape release manually from inside the protected area without

tools.

Ì It must not be possible to reach the escape release from the outside.
Ì The actuator must not be under tensile stress during manual release.

Ì The escape release meets the requirements of Category B according to ENISO13849-1:2008.
Ì The correct function must be checked at regular intervals.
Ì Please observe the notes on any enclosed data sheets.

Ì Fit escape release such that operation, inspection and service are possible.
Ì The actuation axis for the escape release must be inserted min. 10 mm into the handle module. Note the information on

the different prole widths in the chapter 7.9.1. Preparing escape release on page 19.

9. Changing actuating direction

(here: from right to left)

Important!

It is only possible to make this change when the bolt tongue is not extended and an escape release
is not yet mounted.

As supplied, the handle module is set either for doors hinged on the right or for doors hinged on the left.
Based on the example of a handle module for doors hinged on the right this means:

Ì The safety guard opens by pressing down the door handle.
Ì The system is mounted the other way around for doors hinged on the left. In other words, the safety door opens by

pressing up the door handle (see Figure 10). For this reason the actuating direction of the door handle must be changed
(see Figure 10 to Figure 15).

WARNING

In case of an error, loss of the safety function through incorrect connection.

Ì Mounting must be performed only by authorized personnel.
Ì Lay the connection cables with protection to prevent the risk of short circuits.

CAUTION

Risk of damage to equipment or malfunctions as a result of incorrect connection.

Ì All the electrical connections must either be isolated from the mains supply by a safety trans-

former according EN IEC 61558-2-6 with limited output voltage in the event of a fault, or by other
equivalent isolation measures.

Ì Power devices which are a powerful source of interference must be installed in a separate location

away from the input and output circuits for signal processing. The cable routing for safety circuits
should be as far away as possible from the cables of the power circuits.

Ì In order to avoid EMC interference, follow EMC notes on devices in the immediate vicinity of the

MGB system and their cables.

Ì In order to avoid EMC interference, the physical environmental and operating conditions at the

installation site of the device must comply with the requirements according to the standard DIN
EN60204-1:2006, section 4.4.2/EMC.

Ì The function earth must be connected. An M6 threaded bore is available on the mounting plate

for this purpose.

Important!

Ì The supply for further users on the bus may be forwarded via the Euchner MGB system. The entire

supply current through the MGB must not be higher than specied in the chapter 17. Technical
data on page 34.

Ì If the device does not appear to function when operating voltage is applied (e.g. UB LED does not

illuminate), the safety switch must be returned unopened to the manufacturer.

Ì To ensure the stated degree of protection is achieved, the cover screws must be tightened to a

tightening torque of 1 Nm.

Ì Tighten screw for the cover for the mechanical release to 0.5 Nm.

12.1. Notes about

13. Setup

13.1. Integrating into PROFINET and PROFIsafe

NOTICE

The parameters “Update time” and “F-WD-Time” have a decisive effect on the reaction time of the
safety function. The safety function could be lost if the reaction times are too long.

Important!

You will require the corresponding GSD le in GSDML format in order to integrate the MGB system:

Ì GSDML-Vx.x-EUCHNER-MGB-PN_D_110026-JJJMMTT.xml

You can nd the GSD le in the download area at www.euchner.de.
Prior to commissioning, the GSD le must be imported into the conguration software of the control

system (see control system manual).

You must perform the following steps to integrate the MGB system into PROFINET:

1. Congure the MGB system with the conguration software of the control system and assign parameters.
The following PROFINET parameters must be set:

Ì Device name (factory setting from GSD le): [euchnermgb].
Ì IP address: optionally xed or dynamic
Ì Update time

Recommendation [32 ms]
Maximum value [128 ms]
(with number of repeat cycles = 3)

The following PROFIsafe parameters must be set:

Ì F_dest_adr (PROFIsafe address): this is generally assigned automatically by the control system.
Ì F_WD_Time (time during which the control system expects a response by the PROFIsafe device): [xxx ms]. Factory set-

ting from GSD le: [600 ms]

2. Set the PROFIsafe address (F_dest_adr) on the MGB system using the DIP switches (see Figure 16 on page 24).
Important: Identical addresses must be set in the control system and on the device.

3. Save the conguration and transfer it to the MGB system.

13.2. Replacement of an MGB system without programming device

If servicing is required, the MGB system is easy to replace with a new one. For this purpose, the following prerequisites
must be met:

Ì The DIP switch settings (PROFIsafe address) on the new device must match those on the old device.
Ì Your Pronet master must support the automatic replacement of Pronet users.
Ì Your Pronet topology must be correctly congured.
Ì The replacement device must be connected to the same port as its predecessor.
Ì There must be no device name in the MGB system.

This eld is empty in the as-delivered state. Systems that already contain a name must rst be reset to the factory set­tings.

Once these conditions are met, simply replace the old system with the new system.
The Pronet bus does not need to be switched off for this purpose.

13.3. System reset to factory settings

You will nd detailed instructions in the manual for the conguration software for your control system.

(translation of the original operating instructions) 114575-04-03/15

13.4. Teach-in operation (only for MGB unicode)

The handle module must be assigned to the locking module using a teach-in function before the system comprising locking
module and handle module and forms a functional unit.

The system is in a safe state (bits SI 3, SI 4, SI 5, SI 9 and SI 10 are not set) during a teach-in operation.

Important!

Ì The locking module disables the code for the previous handle module if teach-in is carried out for

a new handle module. Teach-in is not possible again immediately for this actuator if a new teach-in
operation is carried out. The disabled code is deleted in the locking module only after a third code
has been taught.

Ì The locking module can only be operated with the last handle module taught.
Ì If, in the teach-in standby state, the locking module detects the handle module taught-in or a

disabled handle module, the teach-in standby state is ended immediately and the locking module
changes to the normal state.

Ì If the bolt tongue is in the operating distance for less than 60 s, the handle module is not taught.

Teaching in handle module

1. Fit handle module.

2. Close safety guard. Check for correct alignment and distance using the marking on the locking module and re-adjust if
necessary.

3. Insert bolt tongue in the locking module.

4. Apply operating voltage to the locking module.

¨ Teach-in operation starts, green LED (State) ashes slowly (approx. 1 Hz). The teach-in standby state is active for 3 min-

utes after switch on. During teach-in, the locking module checks whether the handle module is a disabled handle module.
Provided this is not the case, the teach-in operation is ended after approx. 60 seconds, and the green LED (State) goes
out. The new code has now been stored, and the old code is disabled.

5. Reset via bit O 18 in the data block of the diagnostic function to activate the taught-in code of the handle module in the
locking module.

13.5. Mechanical function test

It must be possible to easily insert the bolt tongue in the locking module. To check, close safety guard several times and
actuate door handle.

If available, check function of the escape release. With active guard locking it must be possible to operate the escape release
from the inside without excessive effort (approx. 40 N).

13.6. Electrical function test

1. Switch the operating voltage on or perform a reset via output bit O 18 in the data block of the diagnostic function.

2. Close all safety guards and insert the bolt tongue into the locking module.
In case of guard locking by solenoid force ¨ activate guard locking.

Ì The machine must not start automatically.
Ì It must not be possible to open the safety guard.
Ì The following applies to MGB-L0: The green LED (State) is illuminated.
Ì The following applies to MGB-L1/2: The green LED (State) and the yellow LED (Lock) are illuminated.

3. Enable operation in the control system.

Ì It must not be possible to deactivate guard locking as long as operation is enabled.

4. Disable operation in the control system and deactivate guard locking.

Ì The safety guard must remain locked until there is no longer any risk of injury.
Ì It must not be possible to start the machine as long as the guard locking is deactivated.
Ì It must be possible to open the safety guard.

Repeat steps 2-4 for each safety guard.
