This short description of the connection and operating instruction is a part of the
scope of delivery.
Application
The AS-i Safety Monitor in Stainless Steel is an emergency stop control device. It mo-
nitors the assigned safety-related AS-i sensors.
The safety unit works with two equal AS-i circuits and creates 16 stand-alone signals.
16 Safety at Work outputs can be controlled by it and up to two safe couple slaves can
be created.
The AS-i safety monitor is approved for safety applications up to Category 4/SIL 3.
Technical data
Safety characteristics
1). Probability of a dangerous loss per hour.
Dimensional drawing
Assembling Disassembling
The AS-i Safety Monitor is mounted on 35 mm standard rails acc. to DIN EN 50 022.
For assembling, position the device on the upper edge of the standard rail and snap
it onto the bottom edge then.
Connection
Maintenance
The proper function of the AS-i safety monitor within the system to be secured, i.e. the
safe shutdown following the triggering of an assigned safe sensor or switch, is to be
checked at least annually by the safety officer.

Specified normal operation of the safety monitor:
The safety monitor has been designed as a disconnecting protective de-
vice to safeguard danger areas on power-driven working materials. The
safe outputs put a machine in the safe state.
For connection and commissioning of the AS-i safety monitor the know-
ledge is assumend of the connecting und operating instructions as well
as operating instructions of ASIMON configuration and diagnostic soft-
ware.
Person protective function:
Safety monitor fulfills a person protective function. Inappropriate instal-
lation puts the function in risk! The manufacturer of the machine/plant at
that one the safety related devices is used is responsible for the correct
and safe total function of all single safety components! Depending on
the choice of safety components to be used the safety system as a who-
le may also be assigned to a lower safety category.

In addition to the reaction time in the monitor, eventually reaction times
of other daisy-chained AS-i components have to be added too. See the
respective technical data for details.
The AS-i and/or the 24 V supply must be made from a PELV power sup-
ply. Its maximal output voltage may not exceed 42 V even in the case of
an error!
Ensure appropiate installation:
Electrical installation is to be performed by trained expert personnel. Du-
ring installation care must be taken that supply and signal leads and also
the AS-i bus cable are laid separately from power cables. In the switch-
gear cabinet it must be ensured that appropriate spark-quenching
equipment is used with contactors. Where drive motors and brakes are
used, attention must be paid to the installation instructions in the corre-
sponding operating instructions. Please note that the maximum line
length of the AS-i bus cable is 100 m. Cables above that length require
the use of a suitable circuit extension.
It is essential to adhere to the prescribed fusing; this is the only way of
guaranteeing safe disconnection in the case of a fault.
This is to be performed by activating each safe AS-i slave at least once
per year and visually inspecting the switching behaviour of the output
circuits of the AS-i safety monitor.
The maximum switch-on time and total operating time depends on the
PFD value selected for the overall failure probability.
When the maximum switch-on time has been reached (three, six or twel-
ve months), the safety system must be checked to ensure that it is
functioning correctly by prompting the shutdown function.
When the total operating time has been reached (20 years), the device
must be checked at the manufacturer's factory to ensure that it is
functioning correctly.
