2-1Operating Manual: PSS 3075-3 Series

Overview

A PSS from the PSS 3075-3 series is a complete programmable safety system in a single unit. The device descriptions provide information on their function. The description are made up of combinations of letters and numbers.

• The PSS 3075-3 contains:

- Power supply

- CPU

- 48 digital inputs, 6 of which are alarm inputs

- 18 single-pole outputs, 4 of which are test pulse outputs

- 9 dual-pole outputs

- Programming device interface (combined RS 232/RS 485 interface)

- User interface (combined RS 232/RS 485 interface)

• In addition to the features on the PSS 3075-3, the PSS SB 3075-3

contains:

- SafetyBUS p-interface

Additional functions

• DP-S Interface for connection to PROFIBUS-DP

• ETH-2 Interface for connection to Ethernet

• CANopen Interface for connection to CANopen

• SE The name "SE“ can be found only on the type label of the PSS (e. g. PSS SB 3075-3 ETH-2 SE). It is a PSS that is identical to the corresponding serial device (e. g. PSS SB 3075-3 ETH-2). The PSS however is intended for use with SafetyEYE and therefore delivered with a preinstalled user program.

• NR Safety system without battery Operation without a battery results in the following restrictions:

- FS section: Remanant data blocks cannot be used.

- ST section: A general reset is performed each time the section

switches from STOP-RUN.

- Each time the PSS is restarted (voltage switched off and then on

again), the system time is reset to zero.

Overview

2-2 Operating Manual: PSS 3075-3 Series

For non-safety-related applications, the PSS can be connected to various standard bus systems (e.g. PROFIBUS-DP). The bus interfaces that are available will depend on the unit type.

INFORMATION

• The standard bus interfaces are described in separate operating manuals. The necessary operating manuals are supplied with the relevant unit types.

• Drivers (standard function blocks) from the corresponding Pilz software package will be required in order to connect to the various standard bus systems.

Example: PSS SB 3075-3 ETH-2 Safety systems PSS 3075-3 with SafetyBUS p- and Ethernet interface.

The digital inputs can be used for local emergency stop monitoring, for example. They are suitable for connecting single or dual-channel input devices, with or without test pulses. The test pulse outputs are suitable for testing input devices. The single or dual-pole outputs can be used to drive valves, for example.

SafetyBUS p enables you to establish a safe decentralised network of several programmable safety systems and/or to connect decentralised modules. The PSS can perform the function of a Management, Logic or Input/Output Device on SafetyBUS p.

WARNING!

Please note: To achieve the corresponding category or requirement class, the whole system including all safety-related components (parts, devices, user program etc.) must be included in the assessment. For this reason, Pilz cannot accept liability for the correct classification into a category or requirement class.

Digital inputs (DI2)

Depending on the application area and its respective regulations, the inputs may be used without test pulses for applications up to category 3, in accordance with EN 954-1. The possibility of a short circuit occurring in the external wiring between different inputs or against L+ must be eliminated through appropriate wiring.

3-3Operating Manual: PSS 3075-3 Series

For category 4 applications, shorts between the input contacts must be detected. This can be achieved through the use of test pulses on the PSS or, depending on the type of input device, through a feasibility test or through detection of shorts across the contacts on the input device (e.g. light barrier) (for connection examples please see Chapter 7, “Wiring the Inputs and Outputs”).

Single-pole outputs (DOS)

An additional shutdown route means that the outputs on the PSS can be used in single-channel operation for applications up to category 3 in accordance with EN 954-1 (03/97). Please note that in this case a feedback circuit must be used. To achieve category 4, two actuators must be connected in series to two different outputs.

Dual-pole outputs (DOZ)

The dual-pole outputs can be used for applications up to

category 4 in accordance with EN 954-1 (03/97).

Operating Manual: PSS 3075-3 Series

4-1

Function Description

CPU

The CPU controls the outputs, reads the inputs and processes / stores the user program and variable data. The failsafe section is designed to be multi-channel, i.e. different CPUs process the user program independently. A four-digit display and several LEDs provide information on the status of the safety system and indicate any errors.

Interfaces

CPU interfaces

The CPU of each programmable safety system in the PSS 3075-3 series provides the following interfaces:

• Programming device interface Combined RS 232 interface (minimum configuration: TxD, RxD, GND)/ RS 485

• User interface Combined RS 232/RS 485 interface (termination is selectable)

For further information please refer to the “System Manual for the PSS-Range”.

SafetyBUS p interface

The programmable safety system from the PSS 3075-3 series may have a SafetyBUS p interface, depending on the unit type. For further information on SafetyBUS p, please refer to the “System Manual for SafetyBUS p”.

Interfaces for standard bus systems

Different interfaces are available for connection to various standard bus systems, depending on the unit type. The standard bus interfaces are described in separate operating manuals. The necessary operating manuals are supplied with the relevant unit types.

Function Description

4-2 Operating Manual: PSS 3075-3 Series

Inputs

Programmable safety systems from the PSS 3075-3 series have 48 digital inputs (DI2), 6 of which can be configured as alarm inputs (DIF).

The digital input signals must show a “High” (“1” signal) of 24 VDC (+15 ... +30 VDC) or a “Low” (“0” signal) of 0 VDC (-3 ... +5 VDC).

LEDs are used as status indicators. An LED lights up as soon as a “1” signal is present at the input. Inputs have input filters and are galvanically isolated from the control electronics through optocouplers.

Digital inputs (DI2)

Internal diagnostic circuitry checks the function of the inputs, including the optocoupler. If an error occurs, the PSS will switch to a STOP condition, switch off the outputs and send a message to the CPU-display.

Alarm inputs (DIF)

The CPU program cycle will be interrupted if there is a signal change at an alarm input. Depending on the configuration, rising, falling or both types of pulse edges may trigger an alarm. Only those alarms triggered by a signal change from “1” to “0” are safety-related. As soon as an alarm signal (signal change) occurs at one of the alarm inputs, the signal is sent to the CPU through a hardware connection. The CPU determines which input triggered the alarm and, if the pulse edge is configured as active, calls up the relevant alarm OB. The user can program whatever measures are necessary into this alarm OB (see “FS System Description”).

Internal diagnostic circuitry checks the function of the inputs. If an error occurs, the PSS will switch to a STOP condition, switch off the outputs and send a message to the CPU-display. The input filter and optocoupler can be tested using test pulses.

Operating Manual: PSS 3075-3 Series

4-3

INFORMATION

For further information on alarm processing please refer to the “FS System Description” from the “PSS System Manual for the compact/modular PSS”

Outputs

Programmable safety systems from the PSS 3075-3 series have 18 singlepole outputs (DOS) and 9 dual-pole outputs (DOZ). 4 of the single-pole outputs can be configured as test pulse outputs (DOT).

INFORMATION

On programmable safety systems from the PSS 3075-3 series, only outputs O1.16 ... O1.21, O/T2.0 ... O/T2.3, O2.8 ... O2.18, O4.0 ... O4.2 and O4.8 ... O4.10 are available at the terminals. Please note: Unwired outputs O1.22 ... O1.31, O2.4 ... O2.7, O2.19 ... O2.31, O4.3 ... O4.7 and O4.11 ... O4.15 cannot be configured in the system software.

Single-pole outputs (DOT/DOS)

Programmable safety systems from the PSS 3075-3 series have 18 singlepole outputs with a load capacity of 1.5 A.

The 4 outputs O/T2.0 ... O/T2.3 can be configured together as test pulse outputs.

Outputs configured as test pulse outputs supply the test pulses to check the input filters and optocouplers on the inputs. The CPU checks whether the inputs connected to a test pulse output can detect a signal change.

INFORMATION

Please note that unused test pulses must remain unconnected.

Function Description

4-4 Operating Manual: PSS 3075-3 Series

Once the CPU sends a “1” signal via the system bus, the PSS will supply 24 VDC to the relevant output. The status of the outputs is displayed through LEDs, which light as soon as a “1” signal (24 VDC) is present at the output.

Internal diagnostic circuitry tests the function of the outputs. During each cycle, the CPU compares the actual status of the outputs with the process image of the outputs. Outputs that are switched on will be switched off during each self test in order to check that the output transistors can be switched. Outputs that are switched off will be switched on during each self test in order to check the monitoring circuit. A test will also be carried out to check for shorts between the outputs of a sub-slot (short circuits are detected only when the outputs are switched on). If an error occurs, the PSS will switch to a STOP condition, switch off the outputs and send a message to the CPU-display. If a plant is particularly sensitive to the pulses from the power-up test on outputs that are switched off, individual outputs or all single-pole outputs can be excluded from testing. This is achieved using operating system call SB255, function 2 (see overleaf).

If you deactivate the output power-up test, please make sure you observe the following guidelines:

NOTICE

On an output that is switched off, follow the instructions below: At a noncritical point in the program, switch the output on and then off again for one PSS cycle. If the output does not switch correctly, the error will be detected and registered by the operating system. To also detect shorts between outputs that are switched off, outputs must be switched on at an offset of one cycle.

NOTICE

To detect whether an output has been excluded from the output test incorrectly, or whether the output test that the user has programmed is effective, an error simulation must be carried out on each safety-related output during commissioning. To do this, the affected output must be switched off (output’s diode not lit up). If you then generate a short circuit between the output and 0 V, the desired error reaction should occur. In the worst case, the error reaction should occur within 30 minutes.

Operating Manual: PSS 3075-3 Series

4-5

• The output power-up tests are a component part of the system’s self check. The self check is carried out when voltage is returned, on start up (transfer from STOP-RUN) and also during operation.

• Operating system call SB255, function 2 in OB120 is required to deactivate the power-up test on start up. To deactivate the power up-test during operation, the operating system call must be contained in a block that is run as part of each cycle. The power-up test will be performed again as soon as the operating system call is no longer present.

NOTICE

Each time SB255, function 2 is called, data words DW200, DW201 and DW202 must be written in full to ensure that outputs are not excluded from the power-up test unintentionally, due to data words being unwittingly overwritten during the program cycle.

Dual-pole outputs (DOZ)

9 dual-pole outputs are available.

The load must be connected between the “+” and “-” terminals. When the CPU sends a “1” signal via the system bus, the PSS supplies 24 VDC to the relevant output. The status of the outputs is displayed through LEDs, which light as soon as a “1” signal (24 VDC) is present at the output.

Internal diagnostic circuitry tests the function of the connected outputs. On outputs that are switched on, the CPU will alternately switch off the “+” and “-” terminals as part of each cycle. This is to check that the corresponding output transistors can be switched off and that there is no interruption to the load. In addition, outputs that are connected but switched off will be switched on for approx. 100 µs during each self test. If an error occurs, the PSS will switch to a STOP condition, switch off the outputs and send a message to the CPU-display.

All outputs are protected against short-circuit, overload and excess temperature. They can switch both resistive and inductive loads.

General requirements

Please note the following:

• The safety system should be installed in an enclosure, e.g. control cabinet, that conforms to the protection class required for the environment.

• When installing the system in an enclosure such as a control cabinet, the environmental data for the safety system must be taken into account. Details can be found in the chapter entitled “Technical Details”.

• Ensure there is sufficient ventilation to prevent heat building up within the control cabinet. Please note the ambient temperature of 0 ... 60 °C.

• In extreme ambient conditions, additional measures may be required in order to keep within the prescribed value range.

• Use low interference panel lighting for inside the control cabinet.

• The safety system must be installed in such a way that there is adequate protection against buttons and switches being operated unintentionally.

CAUTION!

Risk of burns! Do not touch the metal parts of the housing. If the safety system is operated at an ambient temperature of more than 45 °C, surface temperatures on the housing may reach more than 80 °C at full load.

Installing the safety system

There are two options for installing the safety system. Both options are shown in the following illustrations. Drill M4 holes in the control cabinet’s mounting plate, as shown in the illustrations (tolerance: +/-0.3 mm/0.012").

Notes

Operating Manual: PSS 3075-3 Series 6-1

General requirements

Please note the following:

• When selecting the power supply, please refer to the requirements stated under “Technical Details”.

INFORMATION

The output circuits have been designed to guarantee maximum safety. To achieve this, extensive tests are carried out internally. If the supply voltage is interrupted briefly during a test function, the relevant test pulse output will be deemed to be defective. The normal error reaction will occur: the PSS switches to a STOP condition. Remedy: The PSS supply voltage must be buffered.

• Overvoltage and spikes of interference outside the specifications can damage the PSS. In this case the PSS will switch to a safe condition. You should therefore ensure that appropriate EMC measures are taken.

• To achieve the lowest possible residual ripple (< ± 1.2 V), we recommend that you install a three-phase bridge rectifier or regulated supply.

• The size of the fuse will depend on the system’s technical details, the cable cross section and on local regulations.

• The external 24 V supply must be able to provide the following current: Connectors X0 and X7: the current for the internal supply to the PSS, depending on the unit type (see “Technical Details”), plus the maximum permitted load current at connectors X1 and X2 / X8 and X9. The overall load at full load may be a maximum of 10 A each.

WARNING!

Electric shock! Safe electrical isolation must be ensured for the external 24 V supply. Failure to do so could

result in electric shock. Power supplies must conform

to EN 60950, 03/97,

section 2.3, EN 60742, 9/95 or EN 50178, 10/97.

NOTICE

There must be no direct connection between “N” and the 0 V output on the external power supply!

• Please note:

Always connect the supply voltage to X0 and X7. If not, the programmable safety system will not be able to perform various function tests.

• Depending on the relevant national regulations, it may be necessary to connect the 0 V supply to the central earth bar or to use some form of earth fault monitoring (e.g. EN 60204-1, NFPA 79:17-7, NEC: Article

250).

INFORMATION

We recommend that the programmable safety system (“PSS” connection) and the digital outputs (“X1/X2”, “X8/X9” connection) are fed from separate power supplies, to increase the availability of the programmable safety system.

CAUTION!

The maximum permitted load current at connectors X0 and X7 should not be exceeded. Connectors X0 and X7 should therefore be fused (see Fig. 6-1 and 6-2): “PSS” connections: depending on the unit type (see “Technical details”) “X1/X2” and “X8/X9” connections: 10 A each

INFORMATION

If the inputs on the PSS are being used with test pulses, connect L- on the input device supply to the 0 V terminal for the supply voltage (“PWR” connection, connectors X1/X2, X8/X9). Please refer to Chapter 7, “Wiring the Inputs and Outputs”.

Notes on wiring

• Minimum range for cable cross sections on field connection terminals in mm2:

- Power supply: 1.5 (AWG16) ... 2.5 (AWG12)

- Functional earth: 2.5 (AWG12)

Supply Voltage

6-4 Operating Manual: PSS 3075-3 Series

Wiring the Inputs and Outputs

7-2 Operating Manual: PSS 3075-3 Series

Notes on wiring

Where safety-related applications are concerned, it is essential that short circuits and open circuits are unable to cause a hazardous condition within a plant. The way in which this is done will depend on the degree of hazard within the plant itself, the switching frequency of the input devices and the level of safety of the input devices and actuators. You should assess these points in conjunction with the relevant standards or approvals body (e.g. BG or TÜV). Please observe the following when wiring:

• Earthing:

- Connect the housing to the central earth bar.

- A cable cross section of at least 2.5 mm2 should be used.

- Connections should be kept as short as possible.

• Open circuits, short circuits and earth faults:

- In principle it is possible to eliminate short circuits between signals

within electrically-enclosed areas and also outside electrically-enclosed areas when the signals are conducted in different multicore cables. However, all components must meet the relevant regulations in accordance with EN, DIN and VDE.

- Open circuits and earth faults cannot be eliminated.

- With multi-channel input devices with frequent operation, short circuits

and open circuits can be detected via feasibility checks in the control program.

- The input test on the programmable safety system uses test pulses to

enable the system’s operating program to carry out a test to detect open circuits and short circuits.

• If a dual-pole output on the programmable safety system is used to drive the actuators, a test for short circuits and open circuits will automatically be carried out during each cycle. For this purpose the actuator will be switched off for approx. 100 µs.

• Where single-pole outputs or test pulse outputs are being used, a switchoff test will not be carried out in each cycle. The time for the test will depend on the test slices in the configurable self-check.

• Connecting and laying the cables

- Screened cables are not required for digital I/Os. However, if the

connection cables have screening, it should be connected at one end.

Operating Manual: PSS 3075-3 Series 7-3

-

If there are potential sources of interference, screened cables will be required for connecting alarm signals to the alarm inputs (DIF) and, if the alarm inputs are pulsed, for supplying the test pulses. If necessary, the supply to the system can be buffered.

- When switching inductive loads, suppression should not be used to

protect the semiconductor outputs. Errors may occur if suppression cannot be avoided (e.g. on contactors with integral suppression), particulary with RC elements, depending on their capacitive share. Errors will be shown on the PSS display; the PSS will switch to a safe condition.

- Minimum range for cable cross sections on field connection terminals in

mm2: ¤ Digital inputs: 0.5 (AWG20) ... 1.5 (AWG16) ¤ Digital outputs 0.5 (AWG20) ... 1.5 (AWG16) ¤ Test pulse outputs: 0.5 (AWG20) ... 1.5 (AWG16) ¤ Functional earth: 2.5 (AWG12)

- If you use a multi-strand cable with a cross section of 1.5 mm2 to

connect the I/Os, you will need to use ferrules conforming to Parts 1 and 2 of DIN 46228, 0.5 ... 1.5 mm2, Form A or C. To crimp the ferrules you can use crimp pliers (crimp form A or C) conforming to EN 609471, such as the PZ 1.5 or PZ 6.5 from Weidmüller, for example.

- Use copper wiring.

- The torque setting on the terminals should be 0.5 … 0.6 Nm.

NOTICE

Please read the description that accompanies the connection examples! The connection examples can be found on the following pages.

The terms “signal inputs with frequent operation” and “single-channel safe input devices” are used in the connection examples. These terms are defined as follows:

• Signal inputs with frequent operation are signals that change status on several occasions within a period of time.

• Single-channel safe input devices are positively-driven, normally-closed contacts which open on actuation (failsafe principle).

Wiring the Inputs and Outputs

7-4 Operating Manual: PSS 3075-3 Series

Digital inputs

Features:

• 48 digital inputs (DI2) I0.0 ... I0.31, I1.0 ... I1.9 Inputs I3.0 ... I 3.5 can be configured as alarm inputs (DIF)

• Response time: I0.00 ... I0.31: 1 ms I1.0 ... I1.9: 1 ms I3.0 ... I3.5: 0.5 ms

• Only one 0 V terminal needs to be connected to terminals:

- X3 or X4 for digital inputs I0.0 ... I0.16

- X5 or X6 for digital inputs I1.0 ... I1.9, I3.0 ... I3.5

- X10 or X11 for digital inputs I0.16 ... I0.31 However, we recommend both terminals are connected.

• Only input signals which operate in accordance with the failsafe principle (on switching off) are safety-related.

• Signals may be connected to the digital inputs (DI2) using unscreened cables. If there are potential sources of interference, screened cables will be required for connecting alarm signals to the alarm inputs (DIF) and, if the alarm inputs are pulsed, for supplying the test pulses.

If necessary,

the supply to the system can be buffered.

CAUTION!

The connection shown overleaf is only approved for non-safety applications. The connection of input devices for safety-related applications is described in the examples that follow.

Single-pole outputs

Features:

• 18 single-pole outputs O/T2.0 ... O/T2.3, O2.8 ... O2.15, O4.0 ... O4.2 and O4.8 ... O4.10. The 4 outputs O/T2.0 ... OT2.3 can be configured together as test pulse outputs.

• Output current: 1.5 A

• The continuous current over all the outputs must not exceed the following values:

- max. total of 10 A at terminals X1 and X2

- max. total of 10 A at terminals X8 and X9

• The test pulse outputs are push-pull outputs. Do not use the push-pull level to drive a load to L+, otherwise the switch-off test will detect a connection to L+ and will register an error.

• Do not connect two adjacent inputs to the same test pulse.

• The four test pulse outputs can only be configured together as test pulse outputs or as single-pole outputs that do not use test pulses (see Programming Manual). Configuration will be automatic, depending on the number of test pulse outputs used:

Number < 4: O/T2.0 ... O/T2.3 are test pulse outputs Number = 0: O/T2.0 ... O/T2.3 are single-pole outputs

• If only one test pulse is used, the remaining test pulse outputs must remain unconnected.

• Each output is protected against short-circuit, overload and excess temperature. Outputs are designed for resistive and inductive loads.

• All outputs have a common second shutdown route. This means that the programmable safety system can be used in single-channel operation for applications up to category 3 in accordance with EN 954-1 (11/94). Please note that the second shutdown route is only tested when the safety system switches from STOP to RUN and that a feedback loop must be used with single-channel operation. To achieve category 4, two actuators must be connected in series to two different outputs.

• If short circuits occur between the cable from the output to the load and the 24 VDC supply line, it will no longer be possible to switch off the load. Possible remedies:

- Use separate multicore cable for the 24 VDC

- Use dual actuators

- Use an additional shutdown device such as a main contactor

Test pulse outputs O/T2.0 ... O/T2.3 supply test pulses for input devices or are used as single-pole outputs

Dual-pole outputs

Features:

• 9 dual-pole outputs O1.16 ... O1.21, O2.16 ... O2.18

• Output current: 2 A

• The continuous current over all the outputs must not exceed the following values:

- max. total of 10 A at terminals X1 and X2

- max. total of 10 A at terminals X8 and X9

• The operating system on the programmable safety system tests the outputs during each cycle. Any short circuits and open circuits to the load will be detected (short circuits are detected only when the outputs are switched on).

• During testing, the load is isolated from the supply for 100 ... 200 µs in each cycle (depending on the load and cable runs). The load must not switch off during this time. Outputs that are switched off are switched on for approximately 100 µs in order to test the monitoring inputs. The load must not switch on during this time.

• Error messages can occur when testing outputs on which the contactors are smaller than the recommended load. The error messages are triggered by too high an inductance on the contactors. In this case it helps to have a 1 kOhm resistor connected in parallel to the contactor coil.

• Each output is protected against short-circuit, overload and excess temperature. Outputs are designed for resistive and inductive loads.

SafetyBUS p interface (“SafetyBUS p”)

Some unit types have a SafetyBUS p interface. Connection to SafetyBUS p is via a male 9-pin D-Sub connector. Detailed information on SafetyBUS p can be found in the SafetyBUS p manual.

Interfaces for standard bus connections

The standard bus interfaces are described in separate operating manuals. The necessary operating manuals are supplied with each programmable safety system in the PSS 3075-3 series, depending on the unit type.

Operation and Maintenance

Commissioning

• Install the programmable safety system as described in Chapter 5, “Installation”.

• Connect the inputs and outputs as described in Chapter 7, “Wiring the Inputs and Outputs”.

• Supply voltage for the PSS - as described in Chapter 6 “Supply Voltage”

- connect and switch on.

Faults

PSS and SafetyBUS p functionality

If a fault occurs on the safety system or there is a wiring error, the PSS will switch to a STOP condition and output a message to the display. All the decentralised outputs in the I/O-Groups that are assigned to the LD on the PSS will also be switched off. The error stack display in the system software (e.g. PSS-WIN-PRO) can be used to locate the error. The description for error evaluation can be found in the “FS System Description” in the PSS-range manual package.

Standard bus functionality

Various options are available, should a standard bus interface not achieve the correct operating status:

• Evaluation of the relevant LEDs for operating status (see operating manual for the relevant standard bus system)

• The drivers (standard function blocks) of the standard bus systems will provide some diagnostic options (see operating manual for the relevant software package).

• Bus diagnostics via a corresponding network analyzer Network analyzers from various companies are available for the different bus systems. Further information can be found in the operating manual for the relevant analyzer.

Changing the battery

If the battery voltage drops below 2.5 V, the CPU will issue the error message “S-04”. You should then change the battery, Only use a battery type that has been approved by Pilz (see chapter entitled “Technical Details”). Battery types that are approved by Pilz are “UL-Recognized”.

CAUTION!

• Damage due to electrostatic discharge! Electrostatic discharge can damage components on the safety system. Ensure against discharge before touching the PSS, e.g. by touching an earthed, conductive surface or by wearing an earthed armband.

• Data loss! The battery should be changed when the supply voltage is switched off. The CPU will retain data for approx. 2 minutes. If it takes longer to change the battery, data will be lost.

WARNING!

Risk of injury due to improper handling or due to damaged lithium batteries! Lithium batteries may only be exchanged by specialist staff who have been trained to deal with lithium batteries.

Dead batteries must be disposed of properly!

Operation and Maintenance
