Operator vigilance device

The operator vigilance device can be selected via the transmitter software. It is an equivalent to the vigilance control system installed on the locomotive.
Unless the operator does not carry out actions on the transmitter at specific intervals of time (max. 30 seconds plus 7 seconds warning time) it is assumed that the operator is no longer controlling the locomotive with the necessary attention. In this case, the locomotive is brought to an immediate standstill by a rapid braking.

External transmitter antenna

External antennas can be required when the portable transmitter is operated at a fixed place, e.g. inside a control room of a loading station.
The transmitter can be designed in a way that the receiving signal is automatically switched from internal to external antenna when the transmitter is put in the cradle for the fixed operation.

Time Division Multiple Access of Carrier Frequency

This enables up to 3 radio controls to be operated simultaneously and independently of each other on the same transmitter frequency without the involved radio controls mutually affecting or interfering with each other.

Intrinsically safe

In accordance with the ATEX directive II 2G EEx ib IIC T4 the transmitters of the TH-EC/LO series can be manufactured for the use in hazardous zones with explosive atmospheres, category 2, zone 1.
