English

OVERVIEW

MSC is a modular safety system and comprises a base unit (MSC-CB), which can
be configured using the graphic user interface in EUCHNER Safety Designer, and
various expansion modules that can be connected to MSC-CB via the proprietary
MSCB bus.

The base unit MSC-CB, which can also be used as a standalone device, has 8 safe­ty inputs and 2 separate, programmable dual-channel outputs.

The following expansion modules are available: FI8FO2 with inputs and outputs,



FI8, FM4, FI16, SPM0, SPM1 and SPM2 with only inputs, AC-FO2 and AC-FO4 with
only outputs as well as AZ-FO4 and AZ-FO4O8 with positively driven safety relays.
Expansion modules for connection to the commonest industrial fieldbus systems for
diagnostics are also available: CE-PR (PROFIBUS), CE-CO (CanOpen), CE-DN (De­viceNet), CE-EI (ETHERNET/IP), CE-EI2 (ETHERNET/IP-2PORT), CE-PN (Profinet), CE-
EC (ETHERCAT), CE-MR (Modbus RTU), CE-MT (Modbus/TCP).

MSC makes it possible to monitor the following safety sensors and command
switches:

Optoelectronic sensors (safety light curtains, scanners, safety-light barriers), me­chanical switches, safety mats, emergency stop buttons, two-hand controls, which
are all managed via one single, flexible device that can be expanded.

The system is only allowed to comprise a single base unit MSC-CB and a maximum
of 14 electronic expansion modules, of which not more than four are allowed to
be of the same type.

With 14 expansion modules the system can have up to 128 inputs, 16 dual­channel safety outputs and 28 status outputs. The communication between the
base unit (MASTER) and expansion modules (SLAVES) is via the MSCB 5-way bus
(proprietary bus from EUCHNER) that is on the rear side of every module.

In addition, 8 inputs and 16 outputs are available and can be controlled using
sensors (via the fieldbus).

Using the MSC expansion modules FI8, FI16 and FM4, the number of inputs in the
system can be increased such that more external devices can be connected. FM4
also provides 8 outputs of type OUT_TEST.

With the expansion modules AC-FO2 and AC-FO4, the system has 2 or 4 OSSD
pairs to control devices that are connected downstream of the MSC system.

FI8FO2 has 8 inputs and 2 OSSD outputs.

The expansion modules in the CE series make it possible to connect the common­est industrial fieldbus systems for diagnostics and data transmission. CE-EI, CE-
EI2, CE-PN, CE-MT and CE-EC also have an Ethernet connection. CE-US makes it
possible to connect devices with a USB port.

CE-CI1, CE-CI2 are modules in the MSC family that make it possible to connect
MSC-CB to expansion modules further away (<50m). Two CE-CI modules are con-

nected at the required distance using a screened cable (can be ordered from
EUCHNER or as per the table for the technical cable data).

English

The following can be monitored (up to PLe) using the expansion modules for
speed monitoring SPM0, SPM1 and SPM2:

 Standstill, overspeed, speed range
 Direction of motion, rotary motion/linear motion

Up to 4 speed limits can be defined for each logical output (axis).

Each module has two logical outputs that can be configured via EUCHNER Safety
Designer. In this way up to two independent axes can be monitored.

The safety modules AZ-FO4 and AZ-FO4O8 have 4 separate safety relay outputs
and the corresponding 4 inputs for the external device monitoring contacts (EDM).

Two settings are available for the outputs (configuration via the software
EUCHNER Safety Designer):

 2 pairs of connection contacts (2 normally open contacts per output with 2

corresponding feedback loop inputs).

 4 separate individual connection contacts (1 normally open contact per out-

put with 1 corresponding feedback loop input).

Only the module AZ-FO4O8 has 8 programmable signal outputs.

Using the software EUCHNER Safety Designer, complex logic can be configured us­ing logical operators and safety functions such as muting, timers, counters etc.
defined.

All this is achieved using a straightforward, intuitive graphic user interface.
The configuration undertaken on the PC is transferred to the MSC-CB via a USB

connection. The file is saved in the MSC-CB and can also be saved on the proprie­tary M-A1 memory card (accessory). In this way it is possible to copy the configu­ration to a different MSC-CB module quickly.

The MSC system is certified for the highest safety level included in the applicable in-



dustrial safety standards (SIL 3, SILCL 3, PL e, cat. 4).

INSTALLATION

Mechanical mounting

Mount the modules of the MSC system on a 35-mm DIN rail as follows:

1. Connect together a number of rear 5-pin MSCB plug connectors to suit the

number of modules to be installed.

2. Mount the row of plug connectors assembled in this manner on the DIN rail

(first hook on at the top).

3. Mount modules on the rail and during this process place the contacts on

the base of the module over the related plug connector. Carefully push in

module until it noticeably engages.

4. To remove the module, the catch on the rear of the module must be pulled

down with the aid a screwdriver and the module lifted and pull off upward.

The modules of the MSC system are equipped with
terminal blocks for the electrical connections. Each
module can have 8, 16 or 24 terminals.
Each module also has an MSCB plug connector on the
rear (for the communication with the base unit and
the other expansion modules).

ed to the MSC system

All electro-sensitive protective equipment (ESPE) that is connected to the MSC system
must be arranged at a distance that is at least the minimum safety distance S such that
the hazardous point can only be reached after the machine's hazardous movement has
stopped.

 The European standard:

- ISO 13855:2010 (EN 999:2008) Safety of machinery – Positioning of safeguards with

respect to the approach speeds of parts of the human body

contains formulas for the calculation of the correct safety distance.

 Specific information in relation to the correct arrangement can be found in the instal-

lation instructions for each safety device.

 It is to be noted that the total reaction time is dependent on:

the reaction time of MSC + the reaction time of ESPE + the reaction time of machine
(i.e. the time the machine requires to stop the hazardous movement from when the
stop signal is sent).

Electrical connections

 Install safety modules in a housing that meets degree of protection IP54 as a minimum.
 Connect module in electrically isolated state.
 The power supply for the modules must be 24 VDC  20 % (PELV, as per EN 60204-1

(chapter 6.4)).

 MSC is not allowed to be used to supply external devices.
 The same ground connection (0 VDC) is to be used for all system components.

A procedure is described that permits system planners to determine the minimum safety distance between protective
equipment, in particular ESPE (e.g. light curtains), safety mats or pressure-sensitive floors and two-hand controls, and a
specific hazardous point. It contains a rule for the arrangement of protective equipment based on the approach speed and
time taken by the machine to stop, where corresponding extrapolation is possible, such that also interlocking devices with­out guard locking are also included.

MSC configuration memory (M-A1)

An optional backup memory card (called
M-A1) can be installed in the MSC base
unit MSC-CB for backing up the software
configuration parameters.

Every new project that is transferred from
the PC to MSC-CB is written to the memory
card M-A1.



Always switch off MSC-CB before log­ging onto or logging off from the M­A1.

Insert card in the slot on the rear of the
MSC-CB (direction as shown in Figure 3 –
M-A1).

MULTIPLE LOAD function

To configure several MSC-CB modules
without using a PC and the USB port, the
required configuration can be saved on
one memory card M-A1 and then down­loaded from there to the MSC-CB modules
to be configured.

 If the file on the M-A1 memory card is not identical to the file in the MSC-CB, the con-

figuration data in the MSC-CB are overwritten and therefore permanently deleted.
WARNING: ALL THE DATA THAT WERE IN THE MSC-CB WILL BE LOST.

English

RESTORE function

If the module MSC-CB is faulty, it can be replaced with a new module. As the entire config­uration is saved on the M-A1 memory card, it is only necessary to insert this card in the
new module and switch on the MSC system, the backed up configuration will then be
loaded immediately. In this way interruptions in operation can be reduced to a minimum.

The LOAD and RESTORE functions can be deactivated using the software (see Figure 32).



The expansion modules must be assigned addresses during installation so they can



be used (see NODE_SEL).

 Each time M-A1 is used, it is to be carefully checked whether the configuration selected

is the configuration prepared for this specific system. Undertake a complete function
check on the system comprising the MSC and all devices connected to it (see
CHECKING the system).

CHECK LIST AFTER INSTALLATION

With the MSC system, faults can be detected in the individual modules.
To ensure the trouble-free operation of the system, the following checks are to be under­taken during setup and at least once a year:

1. Undertake complete system CHECK (see "CHECKING the system")

2. Check whether all cables are inserted correctly and the terminal blocks are tightened

properly.

3. Check whether all LEDs (indicators) illuminate correctly.

4. Check whether all sensors connected to the MSC system are positioned correctly.

5. Check whether the MSC system is properly fastened to the DIN rail.

6. Check whether all external indicators (lamps) function correctly.

After installation, maintenance or changing the configuration, undertake system



CHECK as described in section "CHECKING the system" on page 75.

INPUTS

MASTER_ENABLE

The base unit MSC-CB has two inputs: MASTER_ENABLE1 and MASTER_ENABLE2.

These signals must both be set permanently to logic level 1 (24 VDC) so that the



MSC system functions correctly. If you need to deactivate the MSC system, these in­puts can be set to logic level 0 (0 VDC).

NODE_SEL

The inputs NODE_SEL0 and NODE_SEL1 (on the expansion modules) are used to assign an
address to the expansion modules using the connections given in Table 12:

Table 12

Two modules of the same type are not allowed to be assigned the same address.



English

Proximity switch input on speed monitoring modules SPM

Configuration with combined proximity switches on one axis (Figure 5)

The SPM module can be configured in the "Combined proximity switch" mode for a
measurement using two proximity switches on one axis.

The Performance Level PLe can be achieved under the following conditions:

 The proximity switches must be mounted such that the signals produced overlap.
 The proximity switches must be mounted such that at least one proximity switch is

always actuated (active).

Figure 6

Additional information:

 Proximity switches with a PNP output must be used.
 Proximity switches with a normally open output (NO, output active if switch actuat-

ed) must be used.

 In the conditions stated above the DC is 90%
 Both proximity switches must be of the same type with a MTTF > 70 years.

Using the RESTART_FBK signal input, MSC can monitor a feedback loop signal (External
Device Monitoring – EDM) from external contactors; both manual and automatic forms of
starting can be programmed (see list of the possible connections in Table 13).

 If necessary, the response time of contactors must be monitored using an additional

device.

 The command switch for starting (RESTART) must be installed outside the danger ar-

ea in a place from which there is a clear view of the danger area and the entire work­ing area affected.

 It must not be possible to actuate the command switch from inside the danger area.

OUTPUTS



The maximum number of inputs that can be controlled by
each OUT_TEST output:

- 2 INPUTS (parallel connection) (MSC-CB, FI8FO2, FI8, FM4)

- 4 INPUTS (parallel connection) (FI16)



The maximum permissible length of the cable on the
OUT_TEST output is 100 m.

OUT_STATUS

The OUT_STATUS signal is a programmable digital output for the indication of the state
of:

• An input

• An output

• A node on the logic diagram that has been designed with the aid of the software

EUCHNER Safety Designer.

OUT_TEST

The inputs and the cables can be monitored for short circuits or overload states using the
OUT_TEST signals (Figure 7).

Figure 7

OSSD (MSC-CB, FI8FO2)

The OSSD outputs (Output Signal Switching Device) are short-circuit proof, monitored for
cross circuit and supply:

• In the ON state: Uv -0.75 V – Uv (where Uv = 24 V ± 20 %)

• In the OFF state: 0–2 V eff.

The maximum load of 400 mA @ 24 V corresponds to a minimum ohmic load of 60 .
The maximum capacitive load is 0.82 F, the maximum inductive load 30 mH.

OSSD (AC-FO2, AC-FO4)

The OSSD outputs (Output Signal Switching Device) are short-circuit proof, monitored for
cross circuit and supply:

• In the ON state: Uv -0.75 V – Uv (where Uv = 24 V ± 20 %)

• In the OFF state: 0–2 V eff.

The maximum load of 400 mA @ 24 V corresponds to a minimum ohmic load of 60 .
The maximum capacitive load is 0.82 F, the maximum inductive load 30 mH.

It is not allowed to connect external devices to the outputs, except if this arrange-



ment is foreseen in the configuration undertaken in the software EUCHNER Safety
Designer.

Each OSSD output can be configured as shown in Table 14:

English

Automatic

The output is only activated, as per the configuration defined by EUCHNER Safety De­signer, if 24 VDC are applied to the related input RESTART_FBK.

Manual

The output is only activated, as per the configuration defined by EUCHNER Safety Designer,
if there is the logical transition 0-->1 on related input RESTART_FBK.

Monitored

The output is only activated, as per the configuration defined by EUCHNER Safety Designer,
if there is the logical transition 0-->1-->0 on related input RESTART_FBK.

This window contains the description of the project layout.

4 > "VISUAL CONFIGURATION" TOOL WINDOW
This window contains the graphic illustration of the project layout.

English

Preparing the diagram

After the selection of the system layout, you can configure the project.
The logic diagram is prepared with the aid of the DRAG & DROP function:

• Select the objects required from the windows described above (the individual objects

are described in more detail in the following) and drag to the design workspace.

• After the selection of an object, the PROPERTY window is activated where you must

complete the fields as necessary.

• You can set a specific numeric value on a slider (e.g. Filter) using the left and right ar-

row keys on the keyboard, or by clicking on the ends of the slider.

• Objects can be linked together by selecting the required pin using the mouse and then

dropping the link on the pin to be connected using Drag & Drop.

• If the PAN function (panning workspace in the window) is needed, select object to be

panned and pan using the arrow keys on the keyboard.

• You can make connections between elements a long way apart using the "Interpage

In/Out" in "Operator/Miscellaneous" component. The "Interpage Out" element must be
assigned a name that corresponds to the related "Interpage In" element to establish the
required connection.

Figure 35

• If an object needs to be duplicated, first you must select it and then you can copy and

paste it by pressing CTRL+C/CTRL+V on the keyboard.

• An object or a link is deleted by selecting the object or the link and then pressing DEL

on the keyboard.

Example for a project

Figure 37 shows an example of a project in which the module MSC-CB is connected to on­ly two safety components (INTERLOCK and E-STOP).
The inputs (1, 2, 3) on the module MSC-CB for connecting the contacts on the safety
components are highlighted in yellow on the left. The MSC outputs (from 1 to 4) are acti­vated as per the conditions that are defined in INTERLOCK and E-STOP (see page 81 E–
STOP and page 83 INTERLOCK).
Click a block to select it and activate the PROPERTY window on the right where you can
configure the activation and test parameters for the block.

Figure 37

At the end of the project preparation phase (or during intermediate steps), you can save

the actual configuration using the button on the default toolbar.

English

Project validation

The completed project must now be validated. This check is made by running the



VALIDATE command ( button on the default toolbar).

Figure 38

If the validation is successful, a sequential number is assigned to the input and output of
the project. This number then appears also in the REPORT and in the MONITOR in
EUCHNER Safety Designer.

The configuration is only transferred after successful validation.

 The validation function only checks whether the programming is appropriate for the

properties of the MSC system. However, this check does not guarantee that the de­vice has been programmed such that all safety requirements for the application are
met.

English

Project report

The system layout can be printed together with the properties of the individual blocks (

button on the default toolbar).

English

 This definition of the PL and the other related parameters as per EN ISO 13849-1 re-

late only to the functions that have been implemented by EUCHNER Safety Designer
in the MSC system, whereby it is assumed that the configuration has been undertak­en correctly.

 The data for all devices connected to the MSC in the application must be taken into

account in the actual PL of the entire application and the related parameters.

 This task is only allowed to be undertaken by the design engineer or the installer.

Connecting to MSC

After you have connected the module MSC-CB to the PC via the USB cable, establish con-

nection using the button. A window with a password prompt appears. Type password
(see "Password protection").

Figure 39

Sending the configuration to the MSC system

Click the button on the default toolbar to send the saved configuration from the PC
to the MSC-CB after the related command is executed. In the MSC-CB the project is saved
in the internal memory and (if fitted) on the M-A1 memory card (password required: level

2).

This function is only available after the successful validation of the project.



Downloading a configuration file (project) from MSC-CB

Click the button on the default toolbar to download a project from the MSC-CB to the
configuration software EUCHNER Safety Designer.

EUCHNER Safety Designer displays the project saved in the MSC-CB (password level 1 is
adequate).

If the project is to be used for other modules of type MSC-CB, the components con-



nected in each case are to be checked (see "System layout" on page 70).

Then undertake a "Project validation" (page 66) and a "CHECKING the system"



(page 75).

English

Configuration LOG

The creation date and the CRC (four-digit hexadecimal code) for a project saved



in the MSC-CB are contained in the configuration file (project).

Up to five sequential events can be recorded in this log. Then the results are over-



written starting with the oldest event.

The log file can be displayed using the button on the default toolbar (password re­quired: level 1).

Figure 40

English

System layout

The actual layout of the MSC system can be checked using the button (password re­quired: level 1). A pop-up window with the following content appears:

- Modules connected

- Firmware version for the individual modules

- Node number (physical address) of the individual modules.

Figure 41

If there is an error in one of the modules detected, the following window appears.
In the example below the node number of module FI8 is not correct (indicated by
red text).

Figure 42

Disconnecting the system

Click the button to disconnect the PC from the MSC-CB. After the disconnection of
the system, then system is reset and restarted with the project transferred.

If the system does not comprise all the modules foreseen in the configuration, this



incompatibility is indicated on the module MSC-CB and the module is not started.
(See SIGNALS).

English

MONITOR (real-time I/O status – text form)

Click the button to activate the monitor (password required: level 1).
A pop-up window with the following content appears (in real-time):

- Status of the inputs (if the object has two or more input connections to MSC, only the first is
indicated in the MONITOR as active; see example shown)

- Input diagnostics

- OSSD state

- OSSD diagnostics

- Status of the digital outputs

- OUT TEST diagnostics.

Figure 43 – Monitor (text form)

English

MONITOR (real-time I/O status – text – graphic)

Click the button to activate/deactivate the monitor (password required: level 1).
Based on the color of the links (Figure 33) the diagnostics can be read (in real-time) as
follows:

RED = OFF
GREEN = ON
DASHED ORANGE = Connection error
DASHED RED = ENABLE pending (e.g. RESTART)

Position the mouse pointer on the link to display the diagnostics.

Figure 44 – Monitor (graphic)

English

Password protection

To upload and save the project, you must enter a password in EUCHNER Safety Designer.

The default password must be changed to prevent tampering (password level 2) or



so that the configuration loaded in MSC is not visible (password level 1).

Password level 1

All operators who use the system MSC-CB must have a level 1 PASSWORD.
Using this password it is only possible to display the LOG file, the layout of the system,
the real-time MONITOR and upload processes.
On the initialization of the system for the first time the operator must use the password ""
(ENTER key).

System planers who know the level 2 password can assign a new password for level 1 (al­phanumeric, max. 8 characters).

Operators who know this password are authorized to upload the project (from MSC-



CB to PC), to edit or to save it.

Password level 2

System planers who are authorized to work on the preparation of the project must know
the level 2 PASSWORD. On the initialization of the system for the first time the operator
must use the password "SAFEPASS" (upper case).

System planers who know the level 2 password can assign a new password for level 2 (al­phanumeric, max. 8 characters).

Using this password the project can be uploaded (from PC to MSC-CB), edited and



saved. In other words, complete control of the PC => MSC system is possible using
this password.

On UPLOADING a new project, you can change the level 2 password.



Should one of these passwords no longer be available, please contact EUCHNER to



request an unlock file (if the unlock file is saved in the correct folder, the button
appears on the toolbar). Press the button to reset the level 1 and 2 passwords to
their original values. This password is only provided to the system planner and can
only be used once.

English

Password change

Click the button to change the PASSWORD after the connection has been established
using the level 2 password.

A window (Figure 45) appears in which the new password can be selected. Type old and
new password in the related fields (max. 8 characters). Click OK.

At the end of the process, disconnect to restart the system.
If an M-A1 memory card is fitted, the new password is also saved on this memory card.

Figure 45

English

CHECKING the system

 After the project has been validated, uploaded to the module MSC-CB and all safety

components have been connected, the system must be checked for correct operation.

This check is made by forcing a status change for each safety component connected to
MSC to check whether the status of the outputs also actually changes.
The following example is intended to explain the CHECK process.

Figure 46

(t1) In the normal operating status (INTERLOCK closed) Input1 is closed, Input2 is

open and the INTERLOCK output set to the "HIGH" logic level. In this mode the
safety outputs (OSSD1/2) are active and a supply voltage of 24 VDC is present
at the related terminals.

(t2) If the INTERLOCK is opened physically, the state of the inputs changes and

therefore also the outputs of the INTERLOCK block: (OUT = 0 VDC--->24 VDC).
The state of the safety outputs OSSD1/2 changes from 24 VDC to 0 VDC. If
this change is detected, the moving INTERLOCK is connected correctly.

 You will find more detailed information on the correct installation of external sen-

sors/components in the installation manual.

 This check must be undertaken for each safety component in the project.

English

OBJECT-SPECIFIC FUNCTION BLOCKS

OUTPUT OBJECTS

OSSD (safety outputs)

The OSSD outputs do not require any
maintenance. Output1 and Output2
supply 24 VDC with an input of "1"
(TRUE) and 0 VDC with an input of "0"
(FALSE).

Each OSSD pair has an input for



RESTART_FBK. This input must al­ways be connected as described in
the paragraph RESTART_FBK.

Parameters

Manual Reset: If selected, a reset can be requested on every change in the input signal.

Otherwise the activation of the output will correspond directly to the input conditions.
There are two types of reset: "Manual" and "Monitored". On the selection of the manual
reset, the system only checks the signal transition from 0 to 1.

With the monitored reset the transi­tion from 0 to 1 and then back to 0
is checked.

Enable Status: If selected, the OSSD

can be connected to a STATUS.

STATUS output

Using the STATUS output (not a safety output) every
point in the diagram can be monitored by connect­ing it to the input. The output supplies 24 VDC with
an input "1" (TRUE) and 0 VDC with an input of "0"
(FALSE).

 WARNING: The STATUS output is NOT a safety output.

English

FIELDBUS PROBE

Using this element the status of any point on the
diagram can be indicated on the fieldbus.
Up to 16 sensors can be used; the bit used to indi­cate the state must be entered for each sensor.
The states are indicated on the fieldbus using two
bytes.

(You will find more detailed information in the
fieldbus manual on the CD-ROM "EUCHNER Safety
Designer".)

 WARNING: The FIELDBUS OUTPUT is NOT a safety output.

English

RELAY

The output relay is a relay output with a normally open contact. The relay outputs are
closed if the input IN is "1" (TRUE), otherwise they are open (FALSE).

Parameters
Category. There are three categories of relay out-

puts:

Category 1. Outputs with a category 1 relay.
Each module AZ-FO4/AZ-FO4O8 can have up to
four of these outputs.

Properties:

 Internal relays are monitored.
 External device monitoring contacts (EDM,

check on FBK 1-4) not used (not required for
category 1).

 Each output can be set to manual or automatic

starting.

Example with external relay Example with the internal relay only

Category 2. Outputs with a category 2 relay with OTE (Output Test Equipment) outputs.

Each module AZ-FO4/AZ-FO4O8 can have up to four of these outputs.

OTE: The OTE (Output Test Equipment) output is normally "1" (TRUE), except if there is an

internal error or a malfunction in conjunction with the feedback loop for external contac­tors (FALSE).

Properties:

 Internal relays are always monitored.
 Monitored external device monitoring contacts

(EDM).

 The output can be configured for manual or

automatic starting. The external device moni­toring (EDM) cannot be activated with manual
starting, only with automatic starting. If, how­ever, manual starting with external device
monitoring is required, special logic must be
used (see information below).

English

Output for the OTE (Output Test Equipment)

 Activation: this is necessary for category 2 configurations for signaling dangerous fail-

ures as per EN 13849-1: 2006 / DAM1 (in preparation).

 OTE output: normally ON. If there is a fault in the internal feedback or the external de-

vice monitoring (EDM) => OFF. This signal makes it possible to stop hazardous move­ments, or at least to indicate the fault to the operator.

Usage of the automatic start (A) or manual start (B) (category 2)

Figure 47

Category 4. Outputs with a two category 4 relays. Each

module AZ-FO4/AZ-FO4O8 can have up to two of these
outputs. The relays are operated in pairs for this out­put.

Properties:

 2 dual-channel outputs.
 Double internal relays are monitored.

 Each output can be set to manual or automatic start-

ing.

To avoid affecting the result of the calculation of the PL, the inputs (sensors or safety



components) must correspond to the same or a higher category as the other devices
in the chain.

English

Example of usage with only the internal relay
and monitored solenoid valves

Example of usage with external
contactors and feedback

Manual Reset: If selected, a reset can be requested each time the IN input signal drops

out. Otherwise the output is activated directly corresponding to the state of the IN input.

There are two types of reset: "Manual" and "Monitored". On the selection of the manual
reset, the system only checks the signal transition from 0 to 1. With the monitored reset
the double transition from 0 to 1 and then back to 0 is checked.

Enable Status: If selected, the relay outputs can be connected to a STATUS.

Enable external K reading: If activated, the switching times for external contactors can be

read and checked:

 For category 1 it is not possible to check the external contactors.
 For category 4 the check on the external contactors is obligatory (always activat-

ed).

External K delay (ms): Set maximum delay on the contactors. Using this value the maxi-

mum delay between switching the internal relay and the switching of the external contac­tors (on activation and deactivation) can be defined.

English

INPUT OBJECTS

E–STOP

The input status of an emergency stop device can be
checked using the E-STOP function block. If the
emergency stop button is pressed, the OUTPUT out­put is "0" (FALSE), otherwise the OUTPUT output is "1"
(TRUE).

Parameters

Input Type:

- Single NC – makes it possible to connect emergen-

cy stop devices with one normally closed contact

- Dual NC – makes it possible to connect emergency

stop devices with two normally closed contacts.

Manual Reset: If selected, a reset can be requested on

every activation of the emergency stop. Otherwise the
activation of the output will correspond directly to
the input conditions.
There are two types of reset: "Manual" and "Monitored". On the selection of the manual
reset, the system only checks the signal transition from 0 to 1. With the monitored reset
the double transition from 0 to 1 and then back to 0 is checked.

WARNING: If Manual Reset is selected, the next Input must be used. Example: If In-



put1 and Input2 are used for the function block, Input3 must be used for the reset
