Previous version unit:

Timer type was changed using PRO1 mode. The ‘TIMER’
setting in NAVI mode could onlybe turned on or off.

After change : The type of timer can be changed using the

‘TIMER’ function in NAVI mode.

Display changes

1. Checking blinking of sensitivity margin

The stable margin display method after teaching has been changed.

2. Initial direct code value changed

The factory default settings for the direct codes have been changed.

2. Checking threshold value in RUN mode

After change: The threshold values can be checked by turning the jog switch.

Previous version unit 0000

10 ms is ‘4’, so this has been changed.

After change 0004

Internal circuit changes

1. Addition of an APC circuit

A four-chemical emitting element which provides stable sensing
over long periods has been added, as well as an APC (Auto
Power Control) circuit that improves stability during short periods.

series at the left-most position (when
viewed from the connector side).

Every time the jog switch and the MODE key are pressed simul­taneously, the indicated No. will change from ‘5’n‘0’n‘0’n‘3’n‘5’ in turn.

Notes: 2)

When the optical communications spec. is set to ‘3 (the optical communications
spec. of the group A)’, be sure to mount the units close together. Furthermore,
take care of the following.

The optical communications function may not be usable due to the environment. etc.
Do not carry out the collective channel load or save.

Settings for NAVI Mode

4-1. NAVI Mode Functions and Settings

4

In [NAVI mode], frequently changed settings can be easily configured.
Settings for four functions can be configured.

RUN :

Normal Sensing Operation

TEACH : Teaching Mode

This indicates normal sensing operation. Incident light intensity is displayed in real
time. The factory setting is that the ‘threshold value’ cannot be changed directly.
When the ‘Adjust Lock Function’ in ‘PRO5 Mode’ is disabled, manual fine adjustment
of the ‘threshold value’ can be performed during normal sensing operation.
The threshold value can be confirmed by turning the jog switch (Refer to p.59). In
addition, key lock function can also be set (Refer to p.59).

This mode sets the ‘threshold value’ by utilizing teaching.

When using FX-301(P)(-HS) or FX-305(P) normal mode

The ‘threshold value’ can be set with any of the 3 teaching methods, ‘2-level
teaching’, ‘limit teaching’ and ‘full-auto teaching’.

2-level teaching is a method of setting the threshold value by teaching the
amplifier unit two different status conditions - sensing object present and sensing
object absent.
The ‘threshold value’ is usually set using this method.

Sensing operation * Sensing operation when ‘threshold value’

can be fine adjusted

Teaches only the status condition in which no sensing object is within sensing
range (status in which incident light intensity is stable). This method is used to set
a ‘threshold value’ for conducting sensing in the presence of a background, or
when extremely small objects are to be detected.

This method is used to set the threshold value while the sensing objects are still

1-level Teaching

When using FX-305(P) window comparator mode
The ‘threshold value’ can be set with any of the 3 teaching methods, ‘1-level
teaching’, ‘2-level teaching’ and ‘3-level teaching’. By setting two ‘threshold
values’, both ON and OFF can occur between the two threshold value levels.

This sets the shift value to any desired value, and sets the threshold values (1_SL,
2_SL) by means of 1-level teaching.

This carries out 2-level teaching (P-1, P-2) and sets the threshold values (1_SL,

3-level Teaching

This carries out 3-level teaching (P-1, P-2, P-3) and sets the threshold value
(1_SL) between A and B and the threshold value (2_SL) between B and C as
shown in the diagram below.
After teaching, P-1, P-2 and P-3 are automatically assigned in ascending order to
‘A’, ‘B’, and ‘C’.

Furthermore, if the response time has been set in STDF, LONG or U-LG mode,

ADJ : Threshold Value Fine Adjustment Mode

This mode allows fine adjustment of the ‘threshold value’ setting.
When the incident light intensity display has been selected, the threshold value
can be adjusted in increments as low as a one digit.
When the percentage display has been selected, the threshold value can be
adjusted in increments of one digit (varies depending on the ‘threshold value’).
However, when FX-305(P) is in window comparator mode, the percentage display
function cannot be utilized.

When set to ‘L-ON’, the output will be ON if the incident light intensity becomes
greater than the ‘threshold value’.
When set to ‘D-ON’, the output will be ON if the incident light intensity becomes
less than the ‘threshold value’.

When set to ‘L-ON’, if the incident light intensity is between the two ‘threshold
value’ levels, the output will be ON. If the incident light intensity is outside of the
two threshold value levels, the output will be OFF.
When set to ‘D-ON’, if the incident light intensity is between the two ‘threshold
value’ levels, the output will be OFF. If the incident light intensity is outside of the
two threshold value levels, the output will be ON.

This mode allows the selection of output operation from either L-ON (Light-ON), or
D-ON (Dark-ON).

* The factory setting is this mode for FX-305(P). (Refer to p.55)

2-level teaching is a method of setting the ‘threshold value’ by teaching the amplifier two different
status conditions - sensing object present and sensing object absent. The ‘threshold value’ is
usually set using this method.

The digital display will again blink and indicate the incident light intensity reading

and the ‘threshold value’ will be set to a value midway between the incident
light intensities when the sensing object is present and when it is absent. The
blinking MODE indicator / TEACH will stop blinking and continuously light up.
