Checking the radar sensor
Certain types of checks can be performed after opening the SRT LAN down-mast transceiver’s
cover.
! Warning: When the cover of the SRT LAN down-mast transceiver is opened,
the first safety switch called Interlock is activated. For extra safety, this spring
switch which opens at the moment the panel is removed interrupts the
transmission that disables the 700 V High Voltage that the SRT MOS PCB
requires. To carry out a check simulating a closed panel, pull it towards the
outside.
