5.2 Preparation
Unpack the transmitter and before any other operation check the unit for any
shipping damage and check that all the controls and connectors on the front and
rear panels are in good conditions.
Check the mains voltage selector on the rear panel: the selected value is indicated
by an arrow. If required, extract the selector block levering with a little screwdriver
(Fig. 5-2). Rotate the block until the correct printed value corresponds with the
arrow, then reinsert it.
Figura 5-2
If it has been necessary to change voltage, check the fuse value. The required values
are the following:
PTX30-LCD 220-240 Volt - 3,16 A (6x30)
110-120 Volt - 6,30 A (6x30)
PTX60-LCD 220-240 Volt - 6,30 A (6x30)
110-120 Volt - 10,0 A (6x30)
PTX100-LCD 220-240 Volt - 6,30 A (6x30)
110-120 Volt - 10,0 A (6x30)
It is also possible to check the integrity of the RF amplifier section fuse: Its value is
4A for the PTX30-LCD version and 8A for the PTX60-LCD and PTX100-LCD
versions.
Verify that the mains switch on the front panel of the unit is on the OFF position.
Connect to the RF output of the exciter a proper load (a dummy load with suitable
dissipation power, an antenna, a final amplifier or a combiner)
NOTE: When you connect the PTX-LCD to other devices, it is necessary to strictly
follow the instructions given by the resepective manufacturers, to avoid damages
or danger situations.
