pin 11. REMOTE PROGRAM LEVEL.A
Analog remote program level is a user input for remote
control of the RFX output.
To enable this input, "Remote
Signal" must be selected at the front panel.
An analog 0-5
volt signal will program 0 to full output of the RFX.
This
input signal must be referenced to signal common, user pin
18.
pin 12. TUNER ARC SENSE. D
The digital tuner arc signal is an input indicating a chamber
arc.
This is a digital low active signal.
pin 13. INTLK.D
The interlock function allows the user to gain access to the
interlock string.
With the string not satisfied the main
contactor will not close, or if closed, will begin opening
with 1 millisecond of the break.
To satisfy the interlock
command, contact closure to power common, user pin 19 must be
made.
When the interlock string has been satisfied, the
"INTLK" status indicator on the front panel will be
illuminated.
The user connector plug shipped with a new RFX power supply
has a jumper wire installed between INTLK.D and power common.
This will establish the interlock string when this plug is
installed, enabling the unit to recognize an ON command.
pin 14. REFLECTED POWER.A
The analog reflected power signal is a scaled output signal
representing reflected power as measured by the RFX.
The
scaling factor is:
0-5 volts represents zero to full
reflected power of the RFX. The unit limits reflected power
at 400 W, therefore 3.33 VDC is the maximum voltage present
on pin 14.
pin 15. LOAD POWER.A
The analog true power signal is a scaled output signal
representing true output power.
The scaling factor is: 0-5
volts equals zero to full.
