2. Correct use
The safety system MGBS consists at minimum of one locking module MGBS-P-L.-… and one handle module MGBS-H… and
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 command
must be issued. For exceptions, refer to ENISO12100 or relevant C-standards.
Devices from this series are also suitable for process protection.
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 MGBS is only allowed to be operated in conjunction with the intended EUCHNER handle modules and the
related connection components and accessories from EUCHNER.
On the modication of system components, EUCHNER provides no warranty for function.
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 14. Technical
data on page 30).
ÌIf a data sheet is included with the product, the information on the data sheet applies.
ÌIt is only allowed to use components that are permissible in accordance with the table below.

3. Description of the safety function
Devices from this series feature the following safety functions:
Monitoring of guard locking and the position of the guard
(interlocking device with guard locking according to ENISO14119)
ÌSafety function (see chapter 6.8. Switching states on page 9):
- The safety outputs are switched off when guard locking is released (monitoring of the locking element).
- The safety outputs are switched off when the guard is open (monitoring of the door position).
- The guard locking can be activated only if the handle module is located in the switch head (prevention of inadvertent
locking position (faulty closure protection)).
ÌSafety characteristics: category, Performance Level, PFHD(see chapter 14. Technical data on page 30).
Control of guard locking (applies only to guard locking devices according the closed-circuit current principle)
If the device is used as guard locking for personnel protection, control of guard locking must be regarded as a safety function.
The device does not feature a safety characteristic for control of guard locking, because the guard locking solenoid is
completely disconnected from outside the device (no control function within the device). It therefore does not contribute to
the failure probability.
The safety level for control of guard locking is dened only by the external control (e.g. PFHD, ext. for 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
Locking modules 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 a system 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 perform
a personnel protection function.
ÌSafety components must not be bypassed, turned away, removed or otherwise rendered ineffective.
On this topic pay attention in particular to the measures for reducing the possibility of bypassing
according to ENISO14119:2013, section 7.
ÌThe switching operation may be triggered only by handle modules designated for this purpose.
ÌPrevent bypassing by means of replacement handle modules (only for multicode evaluation). For this
purpose, restrict access to handle modules 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. 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 instruc-
tions from www.euchner.com.

6. Function
The device permits the locking of movable guards.
The system consists of the following components as a minimum: coded handle module
(transponder) and locking module.
Whether the locking module learns the complete transponder code (unicode) or not
(multicode) depends on the respective version.
ÌDevices with unicode evaluation: The handle module must be assigned to the locking
module by a teach-in operation so that it is detected by the system. This unambiguous
assignment ensures a particularly high level of protection against tampering. The system
thus possesses a high coding level.
ÌDevices with multicode evaluation: Unlike systems with unicode evaluation, on multi-
code devices a specic code is not requested but instead it is only checked whether the
handle module is of a type that can be detected by the system (multicode evaluation).
There is no exact comparison of the transponder code with the taught-in code in the
safety switch (unicode evaluation). The system possesses a low coding level.
The tongue on the handle module is inserted into the locking module when the guard is
closed. When the operating distance is reached, power is supplied to the handle module by the locking module and data
are transferred.
If a permissible code is detected, the safety outputs are switched on.
The safety outputs and the monitoring output (OL) are switched off when the guard is released.
In the event of a fault in the locking module, the safety outputs are switched off and the DIA LED illuminates red. The
occurrence of faults is detected at the latest on the next demand to close the safety outputs (e.g. on starting).
6.1. Guard lock monitoring
All versions feature two safe outputs for monitoring guard locking. The safety outputs (FO1A and FO1B) are switched
off when guard locking is released.
6.2. Door position monitoring output (OD)
The door position monitoring output is switched on as soon as the door handle is inserted into the switch head (state: guard
closed and not locked). The door position monitoring output also remains switched on when guard locking is active.
6.3. Diagnostic monitoring output (OI)
The diagnostic monitoring output is switched on in the event of a fault (switch-on condition as for DIA LED).
6.4. Guard lock monitoring output (OL)
The guard lock monitoring output is switched on when guard locking is active.
6.5. Version MGBS Extended
Some versions contain additional controls/indicators in the housing cover. Please refer to the corresponding data sheet for
further information.
6.6. Guard locking for version MGBS-L1
(guard locking actuated by spring force and released by power-ON)
Activating guard locking: close guard; no voltage at the solenoid.
Releasing guard locking: apply voltage to the solenoid.
The spring-operated guard locking functions in accordance with the closed-circuit current principle. If the voltage is interrupted
at the solenoid, the guard locking remains active and the guard cannot be opened directly.

Important!
If the guard is open when the power supply is interrupted and is then closed, guard locking is activated.
This can lead to persons being locked in unintentionally.
The tongue on the handle module cannot be pulled out of the locking module and the guard is locked as long as the guard
locking pin is extended.
If a voltage is applied to the guard locking solenoid, the guard locking pin is retracted and the tongue on the handle module
is released. The guard can be opened.
6.7. Guard locking for version MGBS-L2
(guard locking actuated by power-ON and released by spring force)
Important!
ÌGuard locking devices according to the open-circuit current principle are not intended for protecting
personnel.
ÌUse 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.
Releasing guard locking: disconnect voltage from the solenoid.
The magnetically actuated guard locking operates in accordance with the open-circuit current principle. If the voltage is
interrupted at the solenoid, the guard locking is released and the guard can be opened directly!
The guard can be opened as long as no voltage is applied to the guard locking solenoid.
If a voltage is applied to the guard locking solenoid, the guard locking pin is held in the extended position and the guard is
locked.
6.8. Switching states
The detailed switching states for your locking module can be found in the system status table. All safety outputs, monitoring
outputs and display LEDs are described there.

S3
No further release functions can be retrotted on Extended variants with control elements in position
1 (S1) and position 2 (S2).
Some situations require the guard locking to be released manually (e.g. malfunctions or an emergency). A function test
should be performed after release.
More information on this topic can be found in the standard ENISO14119:2013, section 5.7.5.1. The device can feature
the following release functions:
8.1. Auxiliary release and auxiliary key release
In the event of malfunctions, the guard locking can be released with the auxiliary release or the auxiliary key release irre-
spective of the state of the solenoid.
The safety outputs are switched off when the auxiliary release or the auxiliary key release is actuated. Use the safety
outputs to generate a stop command.
The monitoring output OL is switched off; OD can assume an undened state. Open the guard and close it again after re-
setting the auxiliary release. The device will then operate normally again.
Important!
ÌThe tongue on the handle module must not be under tensile stress during
manual release.
ÌAfter use, reset the auxiliary release and screw in and seal the locking
screw (with sealing lacquer, for example).
ÌThe auxiliary key release must not be used to lock the locking module
during servicing to prevent activation of guard locking, for example.

8.5. Wire front release (bowden)
Release via a pull wire. Depending on the type of attachment, the wire front release can be used as an emergency release
or escape release.
The following applies to non-latching wire front releases.
If the release is to be used as an emergency release, one of the following measures must be
taken (see EN ISO 14119:2013, section 5.7.5.3):
ÌInstall the release so that it can be reset only with the aid of a tool.
ÌAlternatively, the reset can be performed at the control system level. E.g. by means of a plau-
sibility check (status of the safety outputs does not match the guard locking control signal).
The emergency-release specications in chapter 8.2 on Page 14apply irrespective of this
information.
Important!
ÌThe wire front release meets the requirements of CategoryB according to ENISO13849-1:2015.
ÌThe correct function depends on the laying of the pull wire and the attachment of the pull handle, and
this is the responsibility of the plant manufacturer.
ÌThe handle module must not be under tensile stress during manual release.
8.5.1. Laying wire front release
Important!
ÌLoss of the release function due to mounting errors, damage or wear.
ÌCheck the release function every time after mounting.
ÌWhen routing the wire front release, ensure that it operates smoothly.
ÌObserve the min. bending radius (100mm) and minimize the number of bends.
ÌThe locking module must not be opened.
ÌObserve the notes on the associated data sheets.

11. Electrical connection
WARNING
In the event of a fault, loss of the safety function due to incorrect connection.
ÌTo ensure safety, both safety outputs (FO1A and FO1B) must always be evaluated.
ÌMonitoring outputs must not be used as safety outputs.
ÌLay the connecting cables with protection to prevent the risk of short circuits.
CAUTION
Risk of damage to equipment or malfunctions as a result of incorrect connection.
ÌThe power supply for the evaluation electronics is isolated from the power supply for the guard
locking solenoid.
ÌThe device generates its own test pulses on the output lines FO1A/FO1B. A downstream
control system must tolerate these test pulses, which may have a length of up to 0.35ms.
Depending on the inertia of the downstream device (control system, relay, etc.), this can lead to
short switching processes.
ÌThe inputs on an evaluation unit connected must be positive-switching, as the two outputs on the
safety switch deliver a level of +24V in the switched-on state.
ÌAll the electrical connections must either be isolated from the mains supply by a safety transformer
according to IEC 61558-2-6 with limited output voltage in the event of a fault, or by other equivalent
insulation measures (PELV).
ÌAll electrical outputs must have an adequate protective circuit for inductive loads. The outputs must
be protected with a free-wheeling diode for this purpose. RC interference suppression units must
not be used.
ÌPower 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.
ÌTo 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 EN60204-1:2006,
section 4.4.2 (EMC).
ÌPlease pay attention to any interference elds from devices such as frequency converters or induction
heating systems. Observe the EMC instructions in the manuals from the respective manufacturer.
Important!
If the device does not appear to function when operating voltage is applied (e.g. green STATE LED
does not ash), the locking module must be returned unopened to the manufacturer.
