Strap 1 is connected from the top terminal of the 1 ohm resistor to the terminal indicated in the table. No entry in a strap column indicates that the strap is not required for that gain setting. The above table is for the initial setting of the receiver in non electrified areas. Where impedance bonds are installed, the setting should be one gain step higher than indicated in the table. When a centre fed transmitter is used, the distances in the table refer to that for each half of the track circuit (ie, from the transmitter to a receiver). 4 R A I L T R A C K

Transmitter on the normal power setting shall be a minimum of 200 metres from a receiver of the same frequency (ie minimum length of TC is 200m). Track circuit arrangements of the following frequencies are prohibited. Equipment in the same location case. Parallel track circuits. Track circuits abutting at an insulated rail joint. Tail cables in the same cable route.

One on each rail) should be a minimum of 200m from a U Type/SF Hz transmitter. A 5kHz axle counter detector should be a minimum of 100m from a Z Type 1580 Hz or 1850 Hz transmitter. Any axle counter detector should be a minimum of 5m from any audio frequency track circuit tuned zone. Any axle counter detector should be a minimum of 15m from any audio frequency track circuit end termination. 6 R A I L T R A C K
