Scope

This manual is valid for all MGB-PN with data structure type B from version number V3.22.0.

Correct use

MGB-L0
The safety system MGB-L0 is an electromagnetic interlocking device without guard locking.
The system comprises at least one interlocking module MGB-L0 and one handle module MGB-H...
In combination with a safety guard, this safety component prevents dangerous machine movements from being performed for as long as the safety guard is opened. A stop command is triggered if the safety guard is opened during the dangerous machine function.
For the control system, this means that
Ì starting commands which cause hazardous situations must become active only
when the safety guard is in the protective position.
MGB-L1/MGB-L2
The safety system MGB-L1 / MGB-L2 is an electromagnetic interlocking device with guard locking and guard lock monitoring.
The system comprises at least one locking module MGB-L1 / MGB-L2 and one handle module MGB-H...
In combination with a safety guard and the machine control, the MGB system pre­vents the safety guard from being opened while a dangerous machine movement is being performed.
For the control system, this means that
Ì starting commands which cause hazardous situations must become active
only when the safety guard is in protective position and the guard locking is in locked position.
Ì The locked position of the guard locking must be released only when the haz-
ardous situation is no longer present.
MGB-L0/MGB-L1/MGB-L2
The interlocking module MGB-L0B-PN.-... and locking module MGB-L1B-PN.-... / MGB-L2B-PN.-... are operated as an IO device in the PROFINET (PROFIsafe).
Before safety components are used, a risk assessment must be performed on the machine, e.g. in accordance with
Ì EN ISO 13849-1, Safety of machinery. Safety related parts of control systems.
General principles for design
Ì EN ISO 12100, Safety of machinery – Basic concepts - General principles for

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
Ì after any setup work Ì after the replacement of an MGB component Ì after an extended period without use Ì after every fault
Independent of these checks, the safe function of the safety guard should be checked at suitable intervals as part of the maintenance schedule.
Warning!
Loss of safety function in the event of incorrect connection or incorrect use.
Ì Safety switches must not be bypassed (bridging of contacts), turned away,
removed or otherwise rendered ineffective. On this topic pay attention in particular to the measures for reducing the pos­sibility of bypassing from EN 1088:1995+A2:2008, section 5.7.
Ì The switching operation is only allowed to be triggered by the intended han-
dle module MGB-H... that is positively fastened to the safety guard. The device is only allowed to be installed and placed in operation by authorized personnel
Ì who are familiar with the correct handling of safety components Ì who are familiar with the applicable EMC regulations Ì who are familiar with the applicable regulations on health and safety and ac-
cident prevention
Ì who have read and understood the operating instructions.
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.

Function

Interlocking module MGB-L0.B-PN.

Together with a handle module, the interlocking module makes it possible to inter­lock movable safety guards. The combination also serves as a mechanical door stop at the same time.
The following switch-on condition applies to safety bit SI1.0 ( see also System status table and section PROFIsafe data bytes):
Ì Safety guard closed (T) Ì Bolt tongue inserted into interlocking module (R)
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.

Locking modules MGB-L1.B-PN. and MGB-L2.B-PN.

Important!
Together with a handle module, the locking module makes it possible to lock movable safety guards. The combination also serves as a mechanical door stop at the same time.
To operate the device as a guard lock according to EN 1088, the signals for door position (T=PROFIsafe bit SI0.2), bolt position (R= PPOFIsafe bit SI0.3) and guard lock monitoring (Z= PROFIsafe bit SI0.4) must be polled in a logical AND operator. This operator is already implemented in the PROFIsafe data block (safety bit SI1.0). As an alternative, you can also link the bits SI0.2 to SI0.4 individually to your control system.
The following switch-on condition applies to safety bit SI1.1 ( see also System status table and section PROFIsafe data bytes):
Ì Safety guard closed (T) Ì Bolt tongue inserted into locking module (R) Ì Locking arm in locking position (guard lock monitoring) (Z)
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
Page 7
Operating Instructions Safety System MGB-L..B-PN.-... (PROFINET)
Version MGB-L1B-...
The locking arm is kept in locked position by spring force and is unlocked by solenoid force (closed-circuit current principle).
Version MGB-L2B-...
The locking arm is kept in locked position by solenoid force and unlocked by spring force when the solenoid is switched off (open-circuit current principle).
Warning!
Ì The safety guard can be opened immediately in the event of interruption of
the solenoid power supply!
Ì Usage only in special cases after strict evaluation of the accident risk (see
EN 1088:1995+A2:2008, section 5.5)! Typical case: If the risk of accidental locking inside a safety guard during a power failure is higher than the risk of ineffective guard locking.

Control of the guard locking

Important!
Important!
From MGB version V2.36.4, the factory ensures that control is possible only from the safe control area. Here, it was determined in the firmware that only bit SO 0.0 is evaluated.
By changing the parameters in the configuration tool of your control system, it can be set that bit O 0.0 (in the safe data block for the MGB evaluation module) is evaluated as well (see description of the data blocks on page 30).
Control of the guard locking via the safe control area does not provide increased safety, as the device-internal control of the guard locking is only of single-channel design.
The following functions depend on the MGB version, the version of the GSD file and the settings made there. Compare the specified versions with those on your device and your GSD file. The version number of your MGB can be found on the type plate (format: V X.XX.X).

What must be observed?
The guard locking can be controlled from the unsafe control area. The combination with the more up-to-date GSD file allows a parameter to specify which bits are to be used for control. However, the device does not support this function. In other words, the setting in your configuration software remains ineffective.

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).
The locking screw must be screwed back in and sealed after use (for example with sealing lacquer). Tightening torque 0.5 Nm.
1. Undo locking screw.
2. Lift locking arm using a screwdriver and actuate door handle.
Important!
The system enters into a latching fault when the mechanical release is actuated. See “System status table LEDs on interlocking/locking module” on page 38, state Signal sequence erroneous (DIA1 flashes 7 times).
Note:
The system might not enter into a latching fault if the mechanical release is actu­ated very slowly.

Escape release (optional)

The escape release is used to open a locked safety guard from the inside without tools.
Warning!
Loss of the safety function due to incorrect mounting of the escape release.
Ì The actuation axis for the escape release must be inserted min. 10 mm into
the handle module.
Ì For profile widths larger than 40 mm and when using mounting plates, use a
250-mm actuation axis (order No. 106 761) and cut it to size.
Ì In case of profile widths smaller than 40 mm, cut actuation axis and protective
sleeve to length.
Ì Align escape release axis at right angles to the handle module. See figure on
left and Figure 8.
Ì Fit escape release such that operation, inspection and maintenance are pos-
sible.
Important!
The system enters into a latching fault when the escape release is actuated. See “System status table LEDs on interlocking/locking module” on page 38, state Signal sequence erroneous (DIA1 flashes 7 times).
Note:
The system might not enter into a latching fault if the escape release is actuated very slowly.

Mounting

Warning!
Mounting must be performed only by authorized personnel.
With two-wing hinged doors, one of the two door wings additionally must be latched mechanically.
Use a rod latch (Item) or a double-door lock (Bosch Rexroth) for this purpose, for example.
Tip!
The color and labeling of pushbuttons and indicators can be modified.
At least two M6 screws each must be used to install the evaluation module and the handle module (tightening torque 4 Nm).
For installation steps see Figure 9. Install system so that
Ì Operation of the mechanical release as well as inspection and maintenance are
possible.

Changing the 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 up for doors hinged on the left. In other
words, the safety guard opens by pressing up the door handle (see Figure 10). For this reason the actuating direction of the door handle must be changed (see Figures 10 - 15).
(This is similar for handle modules for doors hinged on the left.)

Protection against environmental effects

Lasting and correct safety function requires that the system must be protected against foreign bodies such as swarf, sand, blasting shot, etc., which can become lodged in the locking and handle modules. For this purpose a suitable installation position should be selected.
Cover device during painting work!

Electrical connection

Warning!
Mounting must be performed only by authorized personnel.
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 transformer according EN IEC 61558-2-6 with limited output volt­age in the event of a fault, or by other equivalent isolation measures.
Ì For use and operation as per the requirements, a power supply with the
feature "for use in class 2 circuits" must be used. The same requirement ap­plies to the safety outputs. Alternative solutions must comply with the following requirements: a) Electrically isolated power supply unit with a max. open-circuit voltage of 30
V/DC and a limited current of max. 8 A.
b) Electrically isolated power supply unit in combination with fuse as per UL248.
This fuse should be designed for max. 3.3 A and should be integrated into the 30 V/DC voltage section.
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).
Important!
Ì The supply for further subscribers on the bus may be forwarded via the Eu-
chner MGB system. The entire supply current through the MGB must not be higher than specified in the section Technical data.
Ì The function earth must be connected. An M6 threaded bore is available
on the mounting plate for this purpose.
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 Tighten screw for the cover for the mechanical release to 0.5 Nm.

Connections on bus module

The bus module includes the PROFINET connections (X3 and X4) and the power supply connections (X1 and X2). Depending on the version, connection is made via push-pull plugs according to IEC 61076-3-117, variant 14 or 7/8"-plugs according to ANSI/B93.55M-1981 and M12 plugs (d-coded) according to IEC 61076-2-101.
The bus module includes a PPOFINET RT switch for Ethernet connection.

Setup

Integrating into PROFINET and PROFIsafe

Attention:
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 file in GSDML format in order to integrate the MGB system:
Ì GSDML-Vx.x-EUCHNER-MGB_110026-YYYYMMDD.xml
You can find the GSD file in the download area at www.EUCHNER.de.
Prior to commissioning, the GSD file must be imported into the configuration software for the control system (see control system manual).
You must perform the following steps to integrate the MGB system into PROFINET:
1. Configure the MGB system with the configuration software of the control system and assign parameters.
The following PROFINET parameters must be set:
Ì Device name (factory setting from GSD file): [euchnermgb]. Ì IPaddress: optionally fixed 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 setting from GSD file: (600 ms)
2. Set the PROFIsafe address (F_dest_adr) on the MGB system using the DIP­switches (see Figure 16). Important: Identical addresses must be set in the control system and on the device.
3. Save the configuration and transfer it to the MGB system.

Operating Instructions Safety System MGB-L..B-PN.-... (PROFINET)
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 DIPswitch settings (PROFIsafe address) of the new device must match
those of the old device.
Ì Your Profinet master must support the automatic replacement of Profinet sub-
scribers. Ì Your Profinet topology must be correctly configured. Ì The replacement device must be connected to the same port as its predeces-
sor. Ì There must be no device name in the MGB system.
This field is empty in the as-delivered state. Systems that already contain a
name must first be reset to the factory settings.
Once these conditions are met, simply replace the old system with the new system. The Profinet bus does not need to be switched off for this purpose.

System reset to factory settings

You will find detailed instructions in the manual for the configuration software for your control system.

Operating Instructions Safety System MGB-L..B-PN.-... (PROFINET)

Teach-in operation (only MGB unicode)

The handle module must be assigned to the locking module using a teach-in func­tion before the system forms a functional unit.
During a teach-in operation the system is in the safe state (bit SI1.0 /SI1.1 is not set).
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 device 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 the 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.
Ì Teach-in process starts, green LED (DIA1) flashes slowly (approx. 2 Hz). The
teach-in standby state is active for 3 minutes 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 completed after approx. 60 seconds, and the green LED (DIA1) goes out. The new code has now been stored, and the old code is disabled.
5. Reset via bit O0.1 in the data block of the diagnostic function to activate the taught-in code of the handle module in the locking module.

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. It must be possible to operate the escape release from the inside without excessive effort.
26
Page 27
Operating Instructions Safety System MGB-L..B-PN.-... (PROFINET)

Electrical function test

1. Switch the operating voltage on or perform a reset via output bit O0.1 in the data block of the diagnostic function.
2. Close all safety guards and insert the bolt tongue into the locking module. In the 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 yellow STATE LED illuminates continuously.
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.

PROFINET data bytes (data blocks for unsafe func­tions)
The following modules can be present in various combinations in an MGB system:
Ì Bus module, MGB-B-...PN (contains everything required for the PROFINET con-
nection)
Ì Evaluation module, MGB-L. (forms the door locking mechanism together with
the handle module)
Ì Control module, MGB-C. (includes various controls/indicators)
Each MGB module occupies a certain number of PROFINET data bytes in the input and output range of the control system.
The PROFINET data bytes for every MGB module or also individual functions are combined in data blocks (see tables below).
A distinction is made between the following data block types:
Ì Data blocks for MGB modules Ì Data blocks for individual functions
These data blocks are automatically assigned to the designated slots in the con­figuration software of the control system when your MGB system is placed. This assignment changes according to MGB system. The exact assignment of the slots and the exact bit allocation for your device can be seen in the data sheet. The data sheet is included with every MGB system.

Data blocks for MGB modules

All standard functions of an MGB module are combined in these data blocks. Ad­ditional functions, e.g. an optional enabling switch or an optional stacklight, have separate data ranges (see section “Data blocks of individual functions at a glance” on page 31)

PROFIsafe data bytes (data blocks for safe func­tions)
Safe PROFINET data are transmitted in addition to the unsafe PROFIsafe data. They include all information on door position and guard locking, emergency stop and the enabling switch, for example.
The PROFIsafe data block includes all safe functions and is always 6 bytes in size. It is subdivided as follows:
2 input bytes of data for the functions (e.g. emergency stop switch position) 4 input bytes used within PROFIsafe 1 output byte for the functions (e.g. safe control of guard locking) All data bits are present in parallel in the unsafe PROFINET and can be used as a
signaling bit there. IMPORTANT: Never use the signaling bits for safety functions.

Troubleshooting

Latching fault when actuating the escape release

In order to achieve monitoring of the locking device in category 4, PL e according to EN ISO 13849-1, an internal monitoring logic system is integrated into every locking module.
Result: The MGB system enters into a latching fault when the escape release is actuated (refer to the “System status table LEDs on interlocking/locking module” on page 38).
