AXB-PT10/15/30 PosiTrack Camera Controllers
Diagnostic error values
In the Terminal Emulator of the AxcessX or NetLinx Studio program, you can use the
Device
Status
command to diagnose any problems with the PosiTrack Controller. The following is an
example of how to diagnose problems using the
DEVICE STATUS
and
CLEAR ERRORS
commands
to obtain error values that can help you better track any problems.
1.
Turn the PosiTrack Controller On and make sure the proper connections are plugged into the
unit. Open Terminal Emulator.
2.
Type
DEVICE STATUS 90
in the Terminal Emulator. The 90 used in this example is the
Device Number assigned to the PosiTrack.
3.
Give the Emulator at least 5 seconds to respond with an error value, if any exists.
4.
If there is an error present, the emulator displays the number 230 and other values, listed in
the Error Values and Descriptions table on page 42, that correspond to particular problems
encountered during the diagnostic cycle.
5.
Type
SEND_COMMAND 90, "'CLEAR ERRORS'"
to clear the errors in the PosiTrack unit
after the problem is resolved. This command clears all the error messages that may have
appeared while you were diagnosing problems.
6.
Turn the PosiTrack Controller Off and fix the problem.
7.
Turn the unit On once the problem has been fixed.
8.
Repeat steps 3 through 7 until the problem no longer exists.
The following table lists the error values you can get when diagnosing any problem.
Positional Commands (Cont.)
PR
Sets the ramp rate of
the specified output
voltage where time is
the time to ramp the full
range both
down to up
and
up to down
or
optionally just
down to
up
or
up to down
.
This command can be used for servomotor positional mode applications.
Syntax:
"’P<output>R<time>[U|D]’"
Variables (See
Parameters - Send_Commands
section on page 38):
P - output = 3 - 5
R - time = 0 - 255
U\D = Up or Down
Example:
SEND_COMMAND CAM,"’P3R50’"
Sets zoom ramp rate to 5 seconds full range for “down to up” and “up to down.”
"’P4R75U’"
Sets the Focus ramp rate to 7.5 seconds full range for
Down to up
. This command
can be used for motor and servomotor positional mode applications.
"’P5R25D’"
Sets the Iris ramp rate to 2.5 seconds full range for
up to down
only.
When using version 2.04 firmware or higher, the PosiTrack stops all pan and tilt
operations if an error is found. Correct the source of the error and cycle power on the
unit to resume operation. The error channels remain On until a CLEAR ERRORS or
ZAP! command is sent.
