SYMPTOM PROBABLE CAUSE SOLUTION
Normal when transitioning from one
mode to the another.
Normal behavior.
bubbler although lubrication pressure is
stable.
There is a leak in the lubrication
volume. Make sure the lubricating volume and
mounting post are properly connected.
Possible leak in vacuum setup.
Make sure the vacuum and manifold
connections are tight.
Ballast is open on vacuum pump. Close ballast on vacuum pump.
When in absolute mode the reference
pressure is too high.
Vacuum reference sensor is not
properly connected, or activated.
Make sure the vacuum reference sensor is
connected to the isolation valve and the
lower mounting post. The power connection
between the sensor and the FPG must also
be secure.
Bubbler water was added, yet it is now
empty. Supply pressure was turned off or is
too low.
Make sure that the FPG supply pressure is
always on, and above 700 kPa (100 psi).
I aborted an internal calibration and the
internal calibration mass is still
lowered.
To abort an internal calibration, only
press [Operation Abort] one time.
Repeatedly pressing it will force an
early abort and not allow FPG Tools
to raise the calibration mass.
If FPG Tools is in the diagnostics user level
(see Section
6.3.7
), press the up arrow on
the main program functions toolbar (see
Section
6.6.4
).
If FPG Tools is not in the diagnostics user
level, vent all pressure and return to gauge
measurement mode. Then cycle power on
the FPG. Leave the power off at least 5
seconds before turning it back on.
The DUT was setup with an adder
and a multiplier.
Normal behavior (see Section
6.8
).
The DUT output displayed in FPG
Tools doesn't match the displayed DUT
output.
The leading characters to strip or
output command is incorrect for the
DUT.
Use the [Remote Communications] option
to view the actual output of the DUT. Then
edit the DUT
<Leading characters to strip>
and <Command> fields to properly
accommodate the DUT output.
The DUT RS232 or IEEE-488
connection is incorrect.
Make sure the remote interface to the DUT is
secure.
The DUT output always displays
"Error" on the
<Run Display>
in FPG
Tools.
The DUT interface was not setup in
FPG Tools.
Use [Config], [System Setup], <Interface>
to setup the remote interface to the DUT.
Make sure the RS232 or IEEE-488 settings
are correct (see Section
6.6.2.2
).
The RS232 cable is not connected.
The COM1 port of the FPG should be
connected to a COM port on the host PC.
An communications error occurs
interfacing with the FPG8601 and FPG
Tools.
The COM port setup in FPG Tools is
not the COM port that the FPG is
connected to.
The port on the host PC must be specified
using the
[Config], [System Setup],
<Interface> option. The default port settings
"19200,N,8,1" will work as long the FPG
settings are not modified on the FPG remote
terminal.
The VLPC is not enabled in FPG
Tools.
Check the [Config], [System Setup],
<Enable VLPC> option (see Section
6.6.2.1
).
The
<VLPC Control>
window is
disabled.
The VLPC is currently executing a
function.
Check the status bar to determine what
operation is active. If necessary, use the
[Operation Abort] option to end a task that
will not complete.
The RS232 cable is not connected.
A standard RS232 cable must connect the
FPG COM2 port to the VLPC COM1 port. If
this connection is not present, FPG Tools will
not operate the VLPC.
A message displays regarding a
communications error with the VLPC.
The VLPC is not turned on.
There is no indication as to whether or not
the VLPC is turned on. Make sure the power
cord is connected and the "1" is down on the
power switch.
VLPC’s valves will not actuate. Shop air supply pressure too low.
Check that compressor is operational and out-
putting a pressure of at least 700 kPa (100 psi).
