Introduction
Safety technology is of central importance in industrial automation and machine building. If you
want to reduce risks and avoid dangers for people and environment, you need solutions which
satisfy stringent requirements and statutory specifications. The safety modules of the RSTi-EP system
have key features such as emergency-stop circuits and wire-breakage or short-circuit detection.
They meet all SIL 3 requirements according to IEC 62061 and EN ISO 13849-1, category 4, PL e, and
support the safe operation of your system.
By safely shutting down the downstream output modules, the safety modules attain maximum
safety with optimum control. All input sensors are independently supplied via separate voltage paths
and report the current machine status to the control unit. Restarting is either carried out in manual
mode or using the autostart function. In addition, GE safety modules reduce maintenance and
service times and improve response times in case of emergency –thanks to a concept of maximum
transparency, for example, using OSSD outputs.

Safety
This section includes general safety instructions for handling the RSTi-EP system. Specific safety
instructions for specific tasks and situations are given at the appropriate places in the
documentation.
2.1 General Safety Notice
Work on the RSTi-EP products may only be performed by qualified electricians with the support of
trained persons. As a result of their professional training and experience, an electrician is qualified to
perform the necessary work and identify any potential risks.
Before any work is carried out on the products (installation, maintenance, retrofitting), the power
supply must be switched off and secured against being switched on again. Work may be carried out
with safety extra-low voltage.
When working during continued operations, the emergency stop mechanisms must not be made
ineffective. If you need technical help, contact Technical Support. For phone numbers and email
addresses, refer to the General Contact Information page in the front of this manual.
If a malfunction on a RSTi-EP product cannot be fixed after following the recommended measures
(refer to the Chapter, LED Indicators and Troubleshooting), the product in question must be sent back
to GE. GE does not assume any liability if the base or electronic module has been tampered with.
2.1.1 Electrostatic Discharge
RSTi-EP products can be damaged or destroyed by electrostatic discharge. When handling the
products, the necessary safety measures against electrostatic discharge (ESD) according to IEC
61340-5-1 and IEC 61340-5-2 must be observed.
All devices are supplied in ESD-protected packaging. The packing and unpacking as well as the
installation and disassembly of a device may only be carried out by qualified personnel and in
accordance with the ESD information.
2.1.2 Open Equipment
RSTi-EP products are open equipment that may only be installed and operated in lockable housings,
cabinets or electrical operations rooms. Only trained and authorized personnel may access the
equipment.
For applications requiring functional safety, the surrounding housing must meet at least IP 54.
The standards and guidelines applicable for the assembly of switch cabinets and the arrangement of
data and supply lines must be complied with.
2.1.3 Fusing
If EP-190x safe power-feed modules are installed within a RSTi-EP station, a Safety Extra Low Voltage
(SELV) / Protected Extra Low Voltage (PELV) power supply has to be applied to ensure the safety
functions.
The operator must set up the equipment so that it is protected against overloading. The upstream
fuse must be designed such that it does not exceed the maximum load current. The maximum
permissible load current of the RSTi-EP components can be found in the technical data.
In the case of modules without fused sensor/actuator power supplies, all lines to the connected
sensors/actuators must be fused corresponding to their conductor cross-section (as per DIN VDE
0298 Part 4).
To meet UL-specifications in accordance with UL 248-14, a UL-certified automatic fuse or a 10 A fuse
with a medium time-lag.

Chapter3. Safety
6 RSTi-EP Functional Safety Manual GFK-2956A
All connections of the RSTi-EP components are protected against voltage pulses and overcurrent in
accordance with IEC 61131-2, Zone B. The operator has to decide whether additional overvoltage
protection according to IEC 62305 is required. Voltages that exceed +/-30 V may cause the
destruction of Network Adapters and modules.
A feed-in power supply with secure isolation must be used.
2.1.4 Earthing (Functional Earth FE)
Each RSTi-EP I/O module is fitted with an FE spring on the underside which creates an electrical
connection to the DIN rail. In order to establish a secure connection, the assembly must be carried
out carefully in accordance with the instructions (refer to the Chapter, Error! Reference source not
found.). The module is earthed by connecting the DIN rail to the protective earth via the earth
terminal.
2.1.5 Shielding
Shielded lines are to be connected with shielded plugs and fixed on a shield bus in compliance with
the relevant standard (refer to the Chapter, E).
2.2 Intended Use
The products of the RSTi-EP series are intended for use in industrial automation. A RSTi-EP station
with bus Network Adapter and connected modules is intended for the decentralized control of
systems or sub-systems. Through the Network Adapter, every module of a station is integrated into a
fieldbus structure and connected to the control unit. The RSTi-EP products conform to protection
class IP 20 (in accordance with DIN EN 60529), they can be used in potentially explosive atmospheres
rated as Zone 2 (as per Directive 94/9/EC) and in safe zones.
The observance of the supplied documentation is part of the intended use. The products described in
this manual may only be used for the intended applications and only in connection with certified
third-party devices or components.
2.3 Use in a Potentially Explosive Atmosphere

2.4 Notes on Functional Safety
2.4.1 Safety Integrity Level (SIL)
The safety requirements necessary for the safety functions of an application are determined in a risk
analysis. Here, the probability of failure of the safety functions is important. In an operating mode
with a high rate of demand or continuous demand, the probability of dangerous failure per hour
(PFH) must be taken into consideration, whereas in an operating mode with a lower rate of demand,
the probability of dangerous failure on demand (PFD) must be taken into consideration.
According to IEC 61508 and IEC 62061, the safety requirements are graded by the failure limit values
as follows:
Safety Requirements by Failure Limit Values
PFD
PFH
SIL3
< 10-3
< 10-7
SIL2
≥ 10-3 to < 10-2
≥ 10-7 to < 10-6
SIL1
≥ 10-2 to < 10-1
≥ 10-6 to < 10-5
2.4.2 Performance Level (PL)
According to DIN EN ISO 13849-1, the degree to which a safety function contributes to risk
minimisation is defined as the performance level. A distinction is made between the five levels PLa to
PLe with an increasing contribution to risk minimisation.
2.4.3 Safety Categories
Safety categories according to DIN EN ISO 13849-1 describe a minimum level of applicable safety
and to what extent monitoring is required.

•Only use components that have been proven in operation.
•Depending on the established risk level, switches (for example, for position monitoring) may
have to have a redundant design.
•Depending on the required safety level, control devices may have to have a redundant
design. In this regard, make sure to take into account the applicable C standards.

Chapter3. System Overview
GFK-2956A November 2017 9
System Overview
The RSTi-EP safe power-feed modules EP-19xx are intended for
connecting safety-related equipment. The EP-19xx modules are
controlled using contact-based safety transducers and/or safety
transducers with OSSD inputs. The safety function consists of the safe
disconnection of 24 V outputs by switching them Off when there is a
safety circuit failure.
Each EP-19xx module safely switches off all following modules that
are supplied by the output current path and thus creates a safety
segment. A survey of the switchable modules is shown at the end of
this section. The safety segment extends either to the next EP-7641
module or to the end of the station. A safety-related input circuit
together with pulsed inputs is used for detecting broken wires and
short circuits.
In the RSTi-EP system, three types of EP-19xx modules are available:
•EP-1901 (one safe input)
•EP-1902 (two safe inputs)
•EP-1922 (two safe inputs, delayed switching off possible)
With EP-19xx modules, the following safety functions can be
implemented:
•Up to two dual-channel safety circuits (AND linked), for
example, for emergency stop switch, safety door contacts and
safety light curtain
•A range of output modules within a RSTi-EP station is safely
supplied with power via the switched 24 V Safe output.
•EP-19xx modules can be cascaded.
3.1 Safety Function
The safety function of the safe power-feed modules is that the safe
output 24 V Safe is being switched according to the information of the
inputs (Type 3 according to EN 61131-2, N-switching respectively). The
safe status is 24 V switched off (current path for outputs and the
output 24 V Safe is switched off).

Chapter3. System Overview
10 RSTi-EP Functional Safety Manual GFK-2956A
3.2 Sample Design
The following figure exemplifies how to design a safety segment using a EP-19xx module. All output
modules arranged within the safety segment will be switched safely. DI modules can be arranged
within the safety segment, only they do not fulfill any safety function and are not influenced by the
EP-19xx module.
Example Set-up of a Safety Segment (1) with EP-19xx
To switch the 24 V Safe voltage back on, either an automatic or a manual start can be selected.
•Automatic start: the safe output current path is switched on immediately after resetting the
safety circuit(s).
Warning
The Automatic Start option should only be used after a risk analysis has shown
that the application is suitable.
•Manual start: the output current path is only switched on again if the start button has been
held down for a preset length of time.
With the delay SIL module (EP-1922) switching off can be delayed by a defined time so that, for
example, a machine can be shut down in a controlled manner. The delay time can be set in four
steps between 0 and 60 seconds (corresponds to stop category 1 as per EN 60204).

3.3 Transition
Transition Diagram
With the delay SIL module (EP-1922) switching off can be delayed by a defined time so that, for
example, a machine can be shut down in a controlled manner. The delay time can be set in four steps
between 0 and 60 seconds (corresponds to stop category 1 as per EN 60204).
3.4 Safety Level
Depending on the entire safety chain, the EP-19xx modules optimally achieve the following safety
levels:
•SIL3 (as per IEC 61508)
•SIL CL3 (as per IEC 62061)
•PLe (as per DIN EN ISO 13849-1)
•Cat. 4 (as per DIN EN ISO 13849)

Chapter3. Configuration
12 RSTi-EP Functional Safety Manual GFK-2956A
Configuration
An EP-19xx module can be positioned anywhere in the RSTi-EP station. Each safety segment might
include at most 12 switchable modules. Multiple EP-19xx modules and thus safety segments can be
set up in a single station.
When planning a RSTi-EP station with EP-7641 modules, the following requirements must be met:
•The overall current consumption of all switchable modules within a safety segment must be
lower than 100 mA (refer to the table Switch-off Delay and current Consumption).
•Each safety segment might include at most 12 switchable modules.
•The switch-off delay time (discrepancy time) for the safe input channels within a safety circuit
is 500 ms ± 10 ms.
•The load output is not designed for either inductive or capacitive loads.
•The station must be safeguarded with a 8-A super fast fuse.
•A SELV/PELV power supply must be used.
•The safely shut-off systems/applications must get their power only from the safe feed-in
module EP-19xx. Likewise, it must not be possible to feed external energy into the safety
segment elsewhere.
•Relay modules can be located after the safe feed-in module; however their outputs cannot
be safely shut off in case of a malfunction.
•At the SS1 output of the EP-1922, only systems/equipment that do not feed any power back
into the system in the event of a malfunction can be connected.
•Any external short circuits in the wiring of the safe output must be avoided.
•Fault exclusion as per EN ISO 13849-2 must be provided.

GFK-2956A November 2017 13
4.1 Switch-off Delay Time
The turn-off time of a EP-19xx module is 20 ms, caused by the hardware and firmware delay time.
The time required until the output voltage even of the last switchable module of a safety segment is
below 5 V, can be calculated as follows:
Switch off delay [ms] =
Turn-off time of a EP-19xx module
+ Sum of all modules’ hardware delay

4.2 Operation With and Without Test Pulses
All safe power-feed modules provide a test pulse evaluation, so that the highest safety levels can be
achieved (see technical data).
Example of Operation with Test Pulses

Chapter3. Configuration
14 RSTi-EP Functional Safety Manual GFK-2956A
The safe power-feed module EP-1922 might also be operated without test pulses. This is mandatory
whenever an external device producing own test pulses is connected.
Test pulses can be enabled or disabled using the DIP-switches at the module.
