Signal Repeater
The signal repeater displays information sent the track infrastructure to the engineer's cab,
signals the detected carrier frequency of the signal in the track-side part of the train protec-
tion system, signals actions taken by the train protection system and displays maximum
speed. It is also used to configure the operating parameters of the train protection system by
the operator.
The unit is connected to the central unit with a four conductor cable that powers the signal
repeater and secures data communication between the central unit and the signal repeater.
The signal repeater is installed inside of a stand-alone Al enclosure or is a control panel-
mounted device. 4 signal signs, blue light, 4 LED indicators, a three-digit alphanumeric dis-
play and three control buttons are installed on the front. A flexible cabling bundle is installed
on the bottom of the Al enclosure model and the signal repeater is installed on articulated
hinges that may be adjusted to an angle of -30° to +210°. The cabling bundle is installed on
the rear of the model installed in the control panel. The signal repeater is installed in a verti-
cal position.
The control switch determines the active cab of the train protection system.

The full names of the indicators are OI1NO1 to OI1NO14 and OI2NO1 to OI2NO14. Abbreviated labels NO1 to NO14
are used in the operating manual to make it easier to read. Context makes clear the distinctions between signal re-
peater models.
