Control system

The Control Unit has two monitoring
circuits which operate the output relays.
The electronics monitor the electrical
resistance of the connected sensors
which have a dened zero signal
current.
When the sensors are not activated
(normal operating conditions), the out­put relays are energised.
If a break occurs in the supply line bet­ween the sensor and the control unit,
the relays “fault” and “monitoring loop”
are deactivated.
Depending on the internal train signals
and the sensors, the relays “activated”
and “monitoring loop” are deactivated.

IMPORTANT NOTES! Please read!

To ensure correct and safe operation
of the unit, it must be properly trans­ported and stored, properly installed
and commissioned, and operated in
accordance with its intended use.
Only persons familiar with the instal­lation, commissioning and operation,
and with the corresponding qualica­tions to prove their skills, may work
on the units. They must observe the
contents of these instructions, the
information given on the type plate of
the unit and the relevant safety regula­tions for the installation and operation
of electrical systems.

This unit is designed and tested in
accordance with EN 50155 and EN
50121-3-2 and left the factory in a
perfectly safe condition. To maintain this
condition, you must observe the safety
regulations marked WARNING! in these
operating instructions. Failure to
observe the safety regulations can lead
to death, injury to personnel, or damage
to the unit and other systems and
equipment.
Should the information given in these
operating instructions be inadequate
in any way, please contact your local
technical centre, subsidiary or represen­tative.
