less than 2 beams. Changes must occur for 3
consecutive scans to be recognized.

Relay 1 is on when any beam is blocked.
Screen function (section 11) does not effect the
relay in this mode.

UNCTION
The diagnostic scan function is designed to
reduce down time caused by beams that are
permanently blocked, such as caused by a
defective beam, or beams that are blocked for an
extended period of time, as when there is
excessive dirt .
This function automatically ignores these
beams after a predetermined length of time (set
by the user). The user can also set a maximum
percentage of the scanner that can be ignored by
this function. When beams are ignored, Relay 2
will energize, to signal that the scanner needs
attention.
When the blocked beams are cleared, the
scanner automatically returns to normal
operation and output 2 turns off.

Note that all commands are given in the
terminal window. Type the commands as shown,
replacing variables with the values you want,
then press ENTER. After this and any other
parameters have been established and set in the
scanner, save the settings (type SAVE then press
Enter). This will cause the saved parameters to be
used upon power up.
Note that lower case letters indicate variables
that the user needs to fill in. For example “DIAGS
x” would indicate to type DIAGS followed by a
space, followed by a number, say DIAGS 100.
There are two versions of commands used
for this function, a simplified and a complex set.
S
IMPLIFIED
C
OMMAND
Command Format:
DIAGS x
where x is a number representing the length of
time in seconds the beam(s) must be blocked
before the scanner will ignore it. Using this
command, a maximum of about 1/3 of the
beams can be ignored.

The following commands are available. Each
command should be followed by the Enter key.
Command Format:
CMASK?
Reports the current mask setting. Used to diagnose
the problem. Not used to setup the function.
Command Format:
CSCAN?
Reports the diagnostic scan parameter settings.
Not used to setup the function, only to determine
what settings have been given to the scanner.
Command Format:
CSENA?
Reports if the diagnostic scan is enabled or not.
Not used to setup function.
Command Format:
CSCAN n mmm.mmm eee.ee
Sets the diagnostic scan parameters.
n – is a number indicating the number of scans
required for beams to be blocked before they
are ignored
m – sets how often the scanner tests for bad
beams, in milliseconds
e – is the maximum percentage of the scanner
that can be ignored (e.g., 33 = 33%)
Note that n times m will give the length of time
before permanently blocked beams will be
ignored.
Command Format:
CSENA x
where x determines if diagnostic scan is
enabled. Use N for x to disable the diagnostic
scan, and use Y to enable diagnostic scan.
Note that using this command set,
both
CSCAN
and CSENA must be used.
