Incorporates useful functions
Changing each threshold level is cumbersome
Measurement with master workpiece as standard
aAuto-reference function is useful!
aZero-adjust function is useful!
Auto-reference function is an original function developed by
SUNX by which, for example, if there is a reference
pressure change during pressure measurement, the
change is automatically added to the threshold level.
Hence, you need not change the threshold level every time.
Zero-adjust function enables setting of the standard
measured value to ‘0’. Hence, it is useful for an error check
by taking the measured master workpiece value as
standard.

Application
Judging
object height
With auto-reference
function
If auto-reference input is
fed before pressure level
judgement, when the reference pressure changes,
the threshold levels are
automatically
changed
accordingly and correct
judgment is possible.
Height judgment
is easily done by
using the zeroadjust function
and setting the
measured values
of the master
workpiece as ‘0’.

• Using this function, the input value range can be converted to an arbitrary display range (span of 4,000 Nos.
within 9,999 to9,999).
• The values which are desired to be displayed by the
extreme values of the input value range are input as
‘zero scale’ and ‘full scale’.
Example: In case ‘beam interrupted width’ is to be
displayed when using the analog sensor
LA-510 having an output of 1 to 5 V.
Zero-adjust
function
Since the LA-510 outputs an analog voltage of
1 to 5 V, CA2-T2, which has an input range of
1 to 5 V, is used.

• By making the zero-adjust (0-ADJ.) input low for 10 ms,
or more, the output value is forcibly made ‘0’ and
measurement is then done by taking the input value of
this instant as standard ‘0’.
• Zero-adjust function cannot be used when autoreference function is selected.
• If zero-adjust backup is used, the input value is stored
even when the power supply is switched off.
• To cancel the zero-adjust function, put the zero-adjust
setting to OFF. In this case, the standard value will return
to the value before zero-adjust input.
• ON-delay: It makes short duration sensing signal ineffective.
• OFF-delay: It extends the output signal by a fixed time
period (0 to 99.99 sec.).

Power supply
ON-delay function
• This function delays the commencement of measurement by the set time period (0 to 9,999 sec.) from the
instant the power supply is switched on.
• This function automatically compensates the threshold
values according to a change in the reference input value.
• When the auto-reference (A-REF.) input is made Low, the
measured value at that instant is added to each threshold value
(OUT 1, OUT 2 set values) to give the new threshold values.
