Documentation
You must observe all information in this manual as well as in the documents listed in
Safety of personnel and
equipment
The safety of personnel and equipment can only be assured if the safety module is used
correctly (see "Correct usage" on page 1-4).
Error detection
Depending on the wiring and the corresponding setting of the safe output module
parameters, the VersaSafe system can detect various errors within the safety equipment.
Do not carry out any
repairs
Repair work may not be carried out on the safety module.
In the event that an error cannot be removed, please contact GE Intelligent Platforms
immediately, engage a service engineer, or send the faulty module directly to GE Intelligent
Platforms.
Do not open the
housing/security seal
It is strictly prohibited to open the safety module housing. In order to prevent the
manipulation of the safety module and to detect the unauthorized opening of the safety
module, a security seal is applied to the module. This security seal is damaged in the event
of unauthorized opening. In this case, the correct operation of the safety module can no
longer be ensured.
Measures to prevent
incorrect connection and
polarity reversal
Take measures to prevent the incorrect connection, polarity reversal, and manipulation of
connections.
1.2
Electrical safety
Direct/indirect contact
Ensure that all components connected to the system are protected against direct and
indirect contact according to VDE 0100 Part 410. In the event of an error, parasitic voltages
must not occur (single-fault tolerance).
This can be achieved by:
– Using power supply units with safe isolation (PELV).
– Decoupling circuits, which are not SELV or PELV systems, using optocouplers, relays,
and other components meeting the requirements of safe isolation.
Power supply unit for 24 V
supply
Only use power supply units with safe isolation and PELV according to
EN 50178/VDE 0160 (PELV). This prevents short circuits between primary and secondary
sides.
Make sure that the output voltage of the power supply does not exceed 32 V even in the
event of an error.
WARNING: Hazardous body currents and the loss of functional safety
Disregarding instructions for electrical safety may result in hazardous body currents and
the loss of functional safety.
In order to ensure electrical safety, please observe the following points.
