Original operating instructions

Safety Regulations

• The installation, commissioning, modification and retrofitting must
only be performed by a qualified electrician.
• Disconnect the device/the system from the power supply before
starting work. In the case of installation and system errors, mains
voltage can be present on the control circuit in the case of non-
galvanically isolated devices.
• Observe the electrotechnical and professional trade association
safety regulations for the installation of the equipment.
• Opening the case or other manipulation voids any warranty.
Attention
• In the case of improper use or any use other than for the intended
purpose, the device must no longer be used and any warranty
claim is void. Invalidating causes can be:
− strong mechanical loading of the device such as, e.g. in the case
of falling or voltages, currents, temperatures, humidity outside
the specification.
− Always check all safety functions in accordance with the
applicable regulations during initial commissioning of your
machine/system and observe the specified inspection cycles for
safety devices.
• Take the following safety precautions before starting
installation/assembly or dismantling:
1. Disconnect the device/the system from the power supply before
starting work.
2. Secure the machine/system against being switched on again.
3. Confirm that no voltage is present.
4. Ground the phases and short to ground briefly.
5. Cover and shield neighbouring live parts!
• Limited contact protection!
Protection class according to EN 60529.
− Case/terminals: IP 40/IP 20.
− Finger-proof according to EN 50274.
Proper Use
The units must only be used as components of safety devices on
machines intended to protect persons, material and machines.
Only use the unit in accordance with its intended purpose. Also, pay
particular attention to the information in the technical data.

Attention
The frequencies present at the inputs I1, I2, I3 and I4 must
not exceed 2 kHz (cutoff frequency)!
Notes
• The SIL according to EN 61508/EN 62061 or PL/Category
according to EN ISO 13849-1 depending on the external
wiring, the choice of control devices and their location on
the machine.
• In applications with a low demand of the safety function, a
proof-test once a year has to be implemented (The supply
voltage of the device has to be switched off and on again
and the safety function of the device has to be activated to
verify the safety function).
• The device must be protected with a fuse 4 A Operating
Class gG or a circuit breaker 4 A Tripping Characteristics B
or C.
Notes
• The devices must be installed in a switch cabinet with a
protection class of at least IP 54.
• The installation is made on a mounting rail according to
EN 50022-35.
• The mounting rail must be connected to protective earth
(PE).
• The external power supply must comply with the
regulations for low voltages with safe separation (SELV,
PELV according to IEC 60536) and EN 50178 (Electrical
equipment for use in power installations).
• External loads must be equipped with a suitable protection
circuit for the load (e.g. RC elements, varistors,
suppressors) in order to reduce electromagnetic inter-
ference and to increase the service life of the output
switching elements.
Functional Description
In the MSI-SR-SM42OS-xx there are four operating mode
groups A, B, C, D available for safe speed monitoring tasks:
• Zero-speed monitoring (A, B)
• Diverse zero-speed monitoring (C, D) with PLC-signal
