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.

General safety precautions

Safety switches fulfill personnel protection functions. Incorrect installation or tampering can lead to fatal injuries to personnel. Check the safe function of the safeguard 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 settings
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. 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 allowed to be triggered only by the intended handle module MGB-H… that is positively fastened to the 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 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.

Operating Instructions Safety Systems MGB-L..B-PN.-… (PROFINET) and With Data Structure Type B

Function

6.1. Interlocking module MGB-L0.B-PN.
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. The following switch-on condition applies to safety bit SI1.0 (SK): Ì Guard closed (T) Ì Bolt tongue inserted into interlocking module (R)
See also chapter 17. System status table on page 39 and chapter 14.10. PROFIsafe data bytes (data block for safe functions) on page 35. 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-PN. and MGB-L2.B-PN.
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 guard locking for personnel protection according to EN ISO 14119, the signals for door position (T=PROFIsafe bit SI0.2), bolt position (R= PROFIsafe 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 (ÜK=safety bit SI1.1). As an alternative, you can also link the bits SI0.2 to SI0.4 individually in your control system.
The following switch-on condition applies to safety bit SI1.1 (ÜK): Ì Guard closed (T) Ì Bolt tongue inserted into locking module (R) Ì Locking arm in locking position (guard lock monitoring) (Z) See also chapter 17. System status table on page 39 and chapter 14.10. PROFIsafe data bytes (data block for safe functions) on page 35. 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. When the bolt tongue is fully inserted into the locking module, the locking arm locks the bolt tongue in this position. Depending on version, this locking is by spring force or solenoid force.

Operating Instructions Safety Systems MGB-L..B-PN.-… (PROFINET) and With Data Structure Type B
6.3. Guard locking for version MGB-L1
(guard locking actuated by spring force and released by power-ON) Activating guard locking: close guard, no voltage at the solenoid (safety bit SO 0.0 = 0). Releasing guard locking: apply voltage to the solenoid (safety bit SO 0.0 = 1). 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. As long as the locking arm is closed, the bolt tongue cannot be pulled out of the locking module and the guard is locked. When voltage is applied to the guard locking solenoid, the locking arm is opened and bolt tongue is released. The guard can be opened.
6.4. Guard locking for version MGB-L2
(guard locking actuated by power-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 0.0 = 1).
Releasing guard locking: disconnect voltage from the solenoid (safety bit SO 0.0 = 0). 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. When voltage is applied to the guard locking solenoid, the locking arm is held in the locked position and the guard is locked.

6.5. Control of guard locking
From MGB version V2.36.4, the factory setting ensures that control is possible only from the safe control area.
By changing the parameters in the configuration tool of your control system, it can be set whether bit O 0.0 (in the safe data block for the MGB locking module) is evaluated as well (see chapter 14.8.2. Data block for MGB locking module L0, L1 or L2 on page 31).

Important!
The following applies to MGB-L2: 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.

Important!

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 in your GSD file. The version number of your MGB can be found on the type label (format: VX.XX.X).

Manual release

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
In the event of servicing, the guard locking can be released with the auxiliary release irrespective of the state of the solenoid (see Figure 6).
Important!
Ì The system enters into a latching fault when the auxiliary release is actuated. See System status table, signal sequence incorrect status (DIA red, Lock flashes 1 time).
Ì The system might not enter into a latching fault if the auxiliary release is actuated very slowly. Ì The auxiliary release is not a safety function. Ì The machine manufacturer must select and use a suitable release (escape release, emergency
release, etc.) for a specific application. A hazard assessment is required for this purpose. It may be necessary to take specifications 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 release function every time after mounting. Ì Observe the notes on any enclosed data sheets.
The locking screw must be screwed back in and sealed (with sealing lacquer, for example) after mounting and after every use of the auxiliary release. Tightening torque 0.5 Nm. 1. Undo locking screw. 2. Lift locking arm using a screwdriver and actuate door handle.

8.3. Escape release (optional)
The escape release is used to open a locked guard from the inside without tools.
The system enters into a latching fault when the escape release is actuated. See chapter 17. System status table on page 39, signal sequence incorrect status (DIA red, Lock flashes 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 actuate 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 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 profile widths in the chapter 8.3.1. Preparing escape release on page 19. Ì Adjust escape release axis at right angles to the handle module. See Figure 8.

Changing actuating direction

(here: from right to left)
Important! It is possible to make this change only 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 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 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 Figure 10 to Figure 15). (Similarly on handle modules for doors hinged on the left)

Setup

14.1. 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 file in GSDML format in order to integrate the MGB system: Ì GSDML-Vx.x-Euchner-MGB-PN_D_110026-YYYYMMDD.xml You will find the GSD file in the Download area at www.euchner.com. Prior to setup, 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 IP address: 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 from 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 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 configuration and transfer it to the MGB system.

14.2. 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 Profinet master must support the automatic replacement of Profinet devices.

Ì Your Profinet topology must be correctly configured.

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 field is empty in the delivery 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.

EN

The Profinet bus does not need to be switched off for this purpose.

14.3. Resetting system to factory settings
You will find detailed instructions in the manual for the configuration software for your control system.

Operating Instructions Safety Systems MGB-L..B-PN.-… (PROFINET) and With Data Structure Type B

14.4. 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 forms a functional unit.
The system is in a safe state (bits SI02, SI03, SI04, SI1.0 and SI1.1 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 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-in.
Ì The locking module can be operated only with the last handle module taught in. 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 normal operation. Ì If the bolt tongue is in the actuating range for less than 60 s, the handle module is not taught in.

Teaching-in handle module
1. Fit handle module.
2. Close safety device. Check for correct alignment and distance using the marking on the locking module and re-adjust if necessary.
3. Insert bolt tongue into the locking module.
4. Apply operating voltage to the locking module.
¨ Teach-in operation starts, green LED (State) flashes slowly (approx. 1 Hz). The teach-in standby state is active for 3 minutes after switch on. During the teach-in operation, 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 (State) 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 or by switching the operating voltage off and on.

14.5. Mechanical function test
It must be possible to insert the bolt tongue easily into the locking module. To check, close 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).

14.6. 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 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 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 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 guard locking is deactivated. Ì It must be possible to open the guard.

Repeat steps 2-4 for each guard.

14.7. PROFINET data bytes (data blocks for non-safe 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 connection) Ì Locking 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 areas 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.

14.10. PROFIsafe data bytes (data block for safe functions)
Safe PROFIsafe data are transmitted in addition to the non-safe PROFINET data. These data include all information about the door position and guard locking, emergency stop and enabling switch, for example.
The Standard PROFIsafe data block includes all safe functions. It is subdivided as follows: Ì 2 input bytes of data for the functions (e.g. emergency stop switch position) Ì 2 additional input bytes (empty) Ì 4 input bytes used within PROFIsafe Ì 1 output byte for the functions (e.g. safe control of guard locking) All data bits are present in parallel in the non- safe PROFINET data area and can be used as a status bit there.
Important!
Never use the status bits for safety functions!
