Voltage or Current Amplifier Board Checks
To verify proper operation of the amplifier circuit boards:
1. From the ProTesT software, select three I’s and three V’s.
2. Verify that the 350V and SRC ON LEDs illuminate when enabled.
3. If any LED fails to illuminate when enabled, replace the circuit board
for that amplifier. Refer to ”Circuit Board Replacement”
on page 7-17.
Battery Simulator Checks
The Battery Simulator is mounted on the chassis rear. It is equipped with
one non-standard fuse soldered on the circuit board. There are no LED
indicators.
To check the Battery Simulator:
1. Remove the cover (refer to page 7-2) and inspect the Battery
Simulator’s fuse.
The fuse is designated F1 and is located near J4.
2. If shorted, the fuse is ok. If open, the fuse is blown; proceed to step 3.
3. Replace the battery simulator circuit board (04D-0598-01). Refer to
”Battery Simulator” on page 7-19.
Cooling Fan Checks
To verify cooling fan operation, power up the F6150 and listen for the
audible sound of the fans spinning. This sound is the only indication that
the fans are functioning. No LEDs or error messages will appear to
indicate a problem until an over-temperature condition occurs.
C
AUTION
It is very important to verify fan operation at power up. Equipment
damage can result during operation with one or more broken fans.
If one or more of the cooling fans is not operating, perform these steps:
1. Immediately power down the F6150.
2. Remove the cover. Refer to page 7-2.
3. Check that the large inductor (L1) located in the middle of the power
supply circuit board has not broken loose.
• If the L1 inductor has broken loose, replace the power supply
board (04S-0676-01 or 04S-0676-02).
• If the L1 inductor has not broken loose, replace the fan. Refer to
”Cooling Fans” on page 7-22
