WARNING: Disconnect primary power prior to servicing.
DAX-1/DAX-3
Section 3 Operation
3.5.2.3 METERS
Exhaust Temp: Temperature measured on the Output Monitor board. Temperature
Fault (OM TEMP) occurs at 62º C.
V+ DTG: Dead Time Generator adjustment voltage measured on the Exciter/
Controller. This voltage directly corresponds to the transmitter carrier frequency
setting. Scaling is 1V per 100kHz.
V+ ePDM: Enhanced PDM adjustment voltage measured on the Exciter/Controller.
This voltage directly corresponds to the ePDM frequency. V+ePDM = (F
ePDM
–
150kHz)*(2/50kHz) + 6
+48: DC voltage used to drive the PA chopper FETs, Exciter/Controller DTG, Output
Monitor circuitry, and cooling fans. Monitoring of fault condition is set at +/-10%.
+12: DC control voltage used for the PA modules, External I/O, Exciter/Controller, and
Output Monitor circuitry. Monitoring of fault condition is set at +/-10%.
-12: DC control voltage used for the PA modules, External I/O, Exciter/Controller, and
Output Monitor circuitry. Monitoring of fault condition is set at +/-10%.
+5: DC logic voltage used for the External I/O, and Exciter/Controller boards.
Monitoring of fault condition is set at +/-10%.
-5: DC voltage used for the Exciter/Controller board. Monitoring of fault condition is
set at +/-10%.
+3.3: DC logic voltage used for the External I/O, and Exciter/Controller boards.
Monitoring of fault condition is set at +/-10%.
+1.8: DC logic voltage used for the External I/O, and Exciter/Controller boards.
Monitoring of fault condition is set at +/-10%.
RFLD PWR Trip: Reflected power trip adjustment voltage set on the Exciter/
Controller. When set up correctly, this voltage corresponds to a reflected power trip of
100W (peak) per PA.
