Before installing, operating or maintaining the device, read and
understand this manual.

DANGER

ATTENTION

Dangerous tension.
Danger to life or serious injury.

Disconnect the system and device from the power before
starting work.

A secure device function is only guaranteed with certified

Hints

The products described here are designed to perform safety-related
functions as part of an overall plant or machine. A complete safety­related system usually contains sensors, evaluation units, signaling
devices and concepts for safe shutdowns. It is the responsibility of the
manufacturer of a system or machine to ensure the correct overall
function. Tapeswitch is unable to guarantee all the features of a
complete system or machine that was not designed by Tapeswitch. The
overall concept of the controller in which the device is integrated must be
validated by the user. Tapeswitch also assumes no liability for
recommendations that are given or implied by the following description.
Due to the following description, no new warranty, warranty or liability
claims beyond the general tapeswitch delivery conditions can be derived.

Safety Regulations

-

-

The device may only be installed and commissioned by
knowledgeable persons who are familiar with this operating manual
and with the applicable regulations on occupational safety and
accident prevention.
Observe the VDE and local regulations, especially with regard to
protective measures.

- Opening the case or unauthorized modifications will invalidate any
warranty.

- Mount the device in a control cabinet with degree of protection IP 54 or
better; Dust and moisture can otherwise lead to impairments of the
functions.

- Provide sufficient protective wiring at all output contacts for capacitive
and inductive loads.

- The safety function must be triggered during commissioning.

If used as directed and in accordance with this manual, no residual risks
are known. Failure to do so may result in personal injury and property
damage.
The PRSU / M2SI is used for the safety-related release and interruption of
a safety circuit. It can be used to protect people and machinery in
applications with emergency stop pushbuttons, safety gates, self-test (type

4) photocells in accordance with IEC / EN 61 496-1, two-hand switches for

metalworking presses, and other working machines with dangerous
closing movements (Type III C according to EN 574) and for safety-related
safety mats, safety edges and band switches.

Safety Instructions

ATTENTION - AUTOMATIC START!

According to IEC / EN 60 204-1 point 9.2.5.4.2, no automatic start must
be made after stopping in an emergency. Therefore, in the modes with
automatic start, a higher-level control must prevent an automatic start
after an emergency stop.

Operating instructions ENGLISH

Before installing, operating or maintaining this device, these instructions
must be carefully read and understood.

DANGER

CAUTION

Dangerous voltage.
Electric shock will result in death or serious injury.

Disconnect all power supplies before servicing equipment.

Safe operation of the device is only guaranteed when using certified

Important Notes

The product hereby described was developed to perform safety functions
as a part of a whole installation or machine. A complete safety system
normally includes sensors, evaluation units, signals and logical modules
for safe disconnections. The manufacturer of the installation or machine is
responsible for ensuring proper functioning of the whole system. Tapeswitch
cannot guarantee all the specifications of an installation or machine that
was not designed by Tapeswitch. The total concept of the control system
into which the device is integrated must be validated by the user. Tapeswitch
also takes over no liability for recommendations which are given or implied
in the following description. The following description implies no modification
of the general Tapeswitch terms of delivery, warranty or liability claims.

Safety Regulations

- This device must be installed and operated by trained staff who are
familiar with these instructions and with the current regulations for safety
at work and accident prevention.

- Pay attention to applicable local regulations, especially regarding safety
measures.

- Opening the device or implementing unauthorized changes voids any
warranty

- The unit should be panel mounted in an enclosure rated at IP 54 or
superior. Dust and dampness may lead to malfunction.

- Adequate fuse protection must be provided on all output contacts with
capacitive and inductive loads.

- The safety function must be triggered during commissioning

When used in accordance with its intended purpose and following these
operating instructions, this device presents no known residual risks. Non­observance may lead to personal injuries and damages to property.
The PRSU/M2SI is used to enable and interrupt a safety circuit in a safe
way. It can be used to protect people and machines in applications with
e-stop buttons, safety gates, light curtains with selftesting (Type 4) acc. to
IEC/EN 61 496-1, 2-hand controls for presses as well as other production
machinery with dangerous closing action (Type III C to EN 574) and for
safety mats, safety edges and tape switches.

Practical Notes

Operation mode

With the potentiometer on the front plate the operartion mode can be
adjustet. The adjustment must be required before energizied. Adjustment
during energization is not allowed.
Only an automatic start at safety function two-hand control (3) is possible.

MANUAL with common

button

Line fault detection e.g. monitoring of ON-button

If the On-button pressed more than 3 s the adequate output contacts of the
safety function can't be switch. The output contacts can be energized when
the On-button pressed again (0.1 s < t

ON

< 3 s).
A line fault is detected if the On-button more than 10 s is actuated. The
output contacts of the adeauate safety function can only be energized with
a reset or re-start with on an off switching of power supply.

ATTENTION - AUTOMATIC START!

According to IEC/EN 60 204-1 part 9.2.5.4.2 and 10.8.3 it

is
not allowed to restart automatically after emergency stop.
Therefore the machine control has to disable the automatic
start after emergency stop.

Reset and external failures:

The reset input is used to reset external failures (application failures or
removable external failures as e.g. a line fault on reset button). If the reset
signal is connected to the input for more than 3 sec the unit unit makes a
reset. A new reset is only possible when the reset signal had been switched
off temporarily.
If an external failure occurs because both input channels of a safety function
did not switch on or off within the simultanious time, a reset is only possible
if both channels are switched to off state after removing failure cause.
If an external failure occurs in only one safety function, only this function
will be disconnected. The second safety function still continuous to work.

Function setting

The variants with selectable safety functions have 2 potentiometers Fkt.1
and Fkt.2 to select the required function. The following functions are possible:
