4.3.5.9 Remote Reset Control
Verify the alarms can be cleared from a
remote location as follows:
(a) Verify the prerequisites of 4.3.5.1 are
complete and are being met.
(b) The RF output, as displayed by the
RF
KILOWATTS
meter and GUI, will be
rated power.
(c) Inhibit RF power module A’s power
supply by setting the
ON/STANDBY
switch of power supply module A to
standby (toggle down). Power supply
module A will turn off and the
transmitter output power will reduce.
(d) Press the
Status
soft-key to see the
power supply related alarm registered
on the GUI. Set the
ON/STANDBY
switch of power supply module A to on
(toggle up). Remotely activate a
remote
Reset
input to remote interface
PWB's
RESET
terminal(s) [TB3-11 (+)/
TB3-12 (-)].
(e) The RF output, as displayed by the
RF
KILOWATTS
meter and GUI, will
increase to its original value and the
alarm will clear.
4.3.5.10 NxLink Control
Verify the NxLink (if installed) provides a
remote connection to the transmitter as
follows:
(a) Connect a cable between the remote
interface PWB’s 9-pin D-sub connector
A44J8 and a computer with a web
browser installed (e.g., Internet
Explorer).
(b) Enter the GUI’s NxLink Configuration
screen (see 3.6.12.9) and record the
DHCP’d Address
.
(c) Enter the address from step (b) into the
web browser’s address bar. The
transmitter’s remote diagnostic web
page should appear.
(d) Enter the user name
root
and the
password
nautel
(both lower case)
and verify you can access the
application. Log out of the application.
NOTE
Paragraphs 4.3.6 through 4.3.6.4 reference
rated, minimum and maximum operating
power levels for the transmitter. Use Table
1-1 to determine the power levels for a
specific mode and transmitter.
4.3.6 Protection Circuit Checks
Verify the fault detector circuits that monitor
critical parameters of the transmitter and
protect the RF power stages are
functioning within their design limits, as
follows:
NOTE
There is no practical way to control the ac
source voltage. It is also not practical to
simulate faults in the RF drive circuits or
RF output stages without risk to the solid
state devices in the RF power amplifier
stages. The following are go/no go tests of
fault detection circuits that monitor voltages
representing critical parameters.
For all alarm conditions, the remote
interface PWB’s SMY (summary) ALARM
output (TB1-4) is a current-sink-to-ground.
(a) Select local control. Press
Control -
Local
switch noting its integral lamp
turns on and the
Control - Remote
switch's lamp turns off. All other status
lamps will remain the same.
(b) Ensure the RF output displayed on the
RF KILOWATTS
meter and GUI is
rated power.
4.3.6.1 External Interlock
Verify the RF output is inhibited when the
external interlock circuit is not intact, as
follows:
(a) Verify the prerequisites of 4.3.5.1 are
complete and are being met.
