Technical Manual – Installation of switchpoint heating
Switchpoint Heating 1
VELOX Switchpoint heating is designed for connection to 230 Vac.
Type 1: Self‐limiting heating element (The self‐limiting type decreases the heat output at rising temperature). This reduces the energy consumption and prevents errors due to overheating.
Type 2: Parallel resistive element, two outputs; 70 / 90W per meter can be installed with single or double element partially on the switch to supply extra power on the most sensitive part of the switch.
The elements are double‐insulated and lack protective earthing in order to avoid causing signalling faults if dam‐ aged.
The elements are flexible and are mounted using clips and protective channels in stainless steel, 1 m long.
The elements can be supplied in lengths up to 25 meter
The elements are supplied with water‐tight quick‐connections, IP68, with screw bushing.
Connection is made to adapted 4‐way blocks screwed to sleepers with protective plates.
The installation can be supplied complete with PC‐controlled equipment built to customer design specifications. The system has remote access by means of Internet / Ethernet and separately monitoring of each element.
