l Intervention distances adjustable:

from 4 m to 20 m (RDM/20);

from 5 m to 30 m (RDM/30);

from 5 m to 60 m (RDM/60);

from 5 m to 99 m (RDM/99)

l Digital setting of distance in metres. Measurement

resolution: 1 metre, with indication independent

of environmental and ageing-related factors.

l Digital indication of the distance in metres via

luminous display in cabin.

l Acoustic signalling of slowing and stopping

(optional, via Mod. RDM-RC repeater).

l Directivity superior to any other system currently on

the market (-3 dB at 3°).

l Minimal power density of emitted signal: 3,5µW/cm2

in contact with the parabola.

l No danger to people or objects

(limit of Osha=1 mW/cm2

).

l Easy alignment of the reflector with the transmitter,

guided by LED indicators located both on the display

unit and on the parabola.

l Unaffected by normal bridge-crane skew.

l Unaffected by variations in power supply voltage

of +15/-20% at constant rate.

l Unaffected by sudden variations in power supply

voltage due to spikes up to - 40%.

l Measurement unaffected by rising hot air currents,

vibrations, humidity, rain or dust.

l Autodiagnosis of transmitter group, receiver,

frequency modulator, quartz time base and power

supply; any failure is signalled by dropout of the stop

relay.

l No preventive maintenance.

l All operations controlled by a microcomputer.

l Anti-interference filter between conductors and earth

for voltages up to 3 kV for 500 µs or 1500 V 50 Hz for

3 s.

l Electronics unit in IP55 container.

l Operating voltage: 220 V 50/60 Hz;

110 V 50/60 Hz on request.

l Operating temperature: -15 ÷ +70°C.

l Absorbed power: 25 VA.

l Relay current-carrying capacity: 10 A 250 Vca.

l Complies with CE and international regulations

regarding electrical safety and electromagnetic

compatibility (EMC).

l Unrestricted-use transceiver equipment

(ERC/REC 70-03E).
