Installing an RF power module
Refer to Figure 1.4 on page 1-21 , and Figure 1.5 on page 1-23 for this procedure.
1. Verify that the RF power module has been tuned to the carrier frequency (see “RF drive
tuning check” on page 1-35 ).
2. Grasp the handle on the front of the power module and the cutout in the top of the module’s
rear panel. Carefully lift the module and insert it into the transmitter.
3. Carefully align the guide pins and the rear panel connectors, then push the power module
firmly into place.
• The
INHIBIT/TEMP
or other RF power module alarm LEDs may turn on.
4. Install the mounting screw behind J1 at the bottom of the power module’s front panel.
5. Install both mounting screws into the top of the power module’s front panel.
6. Connect the cable removed in Step 2 on page 1-20 to J1. You should hear a relay in the rear
of the transmitter pick up (turn on). If the module is a spare module that was not selected for
operation, no relay pickup will be heard.
7. In the
Status
menu on the front panel GUI, press
Reset
to reset the RF power modules.
WARNING:
The RF power module weighs approximately 20 kg (42 lbs.). Use care
when lifting the module.
CAUTION:
Do not connect a cable to J1 on the RF power module if the front panel LED next to
the text “Do not insert connector at bottom of faceplate when LED is on” is
flashing.
