General
This test specification is formed of the following sections,
which correlate to the competency levels identified in
NR/L2/SIG/30014/B410
1. Inspection
2. Wire Count
3. Function Tests
4. Sighting
5. Correspond
General definitions of terms are given in NR/L2/SIG/30014, however terms specific to this specification are defined in the last section of this specification.
Note: The Siemens SIMIS-W application differs from standard fitments in three main ways:
• There is an Interface case (SSB or TEB) between the electronic interlocking and the signal head,
• The signal head contains no transformers or EKR relays and is fed directly with lamp voltages from the interface case,
• There is a safety requirement for continuous earth bonding.
