  • Page 32 LSP Ex System for Zone 22 User Guide Linescanner Head Cable limitations on LSP Head performance The LSP Head is a fast response precision instrument. However, some cable configurations may limit the practical (useable) scanning speed and the dynamic performance of the LSP Head, through cable capacitance and external noise. The following tables show the recommended cables when considering cable length and scan frequency.
  • Page 33 User Guide LSP Ex System for Zone 22 Linescanner Head 3.2 Water Requirements The Hotspot IR Ex mounting plate has internal water channels with inflow and outflow connections (G1/8 tappings) in the plate edge. There is no preferred flow orientation. However, if the scanner is mounted in a position where one of the water connectors is higher than the other, then the lower connector must be used for the mains water in-flow.
