2) The read-only
Analog Inputs
menu
will show. It’s split in three pages and lists the results of internally carried out
measurements:

Forward Power
: forward output power level

Input Power
: driving input power level

Reflected P.
: reflected power level

BIAS Volt
: bias voltage.

In stand-by mode the
BIAS Volt
value is
NEGAT
(negative), whereas during the normal operation it will be a voltage value

Heatsink T. C
: temperature of the amplifier section heatsink (in °C)

Ambient T. C
: environmental temperature (in °C).

Main Voltage
: power supply voltage of the MOS FETs

Module Curr. 1
: current of the amplifier module # 1

Module Curr. 2
: current of the amplifier module # 2

Module Curr. 3
: current of the amplifier module # 3

Module Curr. 4
: current of the amplifier module # 4 (only with Archimede 4000 and Archimede 5000).

10.5.b
Logic Inputs
menu
This menu allows to check the proper operation of the ON/STAND-BY button by checking its dedicated contacts of the control board.
Moreover, it shows the presence of an external stand-by command coming from the REMOTE connector [14]. Finally, it shows if one
or more alarms are currently released (

13.1).
1) From the
Debug Page
(

10.5), select
Logic Inputs
.
2) Press the knob. The
Logic Inputs
page will be shown (see bottom note):

Start Button
: proper operation of the ON/STAND-BY button. It is tested on the related contacts in the CPU board (in order
to also test the wirings). When pressed,
OFF
changes into
ON

standby
: in case of an active stand-by command, you will see
ON

(alarm name) - if one or more alarms are currently released it/they will be shown from this line (see bottom note)
3) To quit and go back to the
Debug Page
, press the knob.

If one or more alarms will be released, they will be displayed from the 3
rd
line, so the
Logic Inputs
page could be eventually
split in two ones in order to make sufficient room to accommodate the alarm(s). To scroll the alarms, simply turn the knob
counterclockwise.
