bCASCADING AMPLIFIERS
䢇Make sure to add or remove the amplifiers in the power supply off condition.
䢇Make sure to check the allowable ambient temperature, as it depends on the
number of amplifiers connected in cascade.
䢇In case two, or more, amplifiers are connected in cascade, make sure to mount
them on a DIN rail.
䢇When connecting in cascade, mount the amplifiers close to each other, fitting
them between the optional end plates (MS-DIN-E) mounted at the two ends.
䢇
Up to maximum 15 amplifiers can be added (total 16 amplifiers connected in cascade.)
䢇When connecting more than two amplifiers in cascade, use the sub cable
(CN-71-
C
M
)
as the quick-connection cable for the second amplifier onwards.
䢇Since the model setting gets changed if collective teaching is done for the ampli-
fiers in Leak setting (F7 mode) and in Liquid setting (F9 mode) mounted in cas-
cade, note that collective teaching should not be done for amplifiers with different
model settings mounted in cascade.
䢇Since the communication function of this sensor and that of the digital fiber sen-
sor FX-301(P)/311(P) is different, if these models are mounted in cascade, do
not use the communication function.
䢇In case of cascading, wait for 10 minutes, or more, to use the teaching function
after the power is switched on.
qMount the amplifiers, one by one, on the
35mm width DIN rail.
(For details, refer to cMOUNTING.)
wSlide the amplifiers next to each other,
and connect the quick-connection cables.
eMount the optional end plates
(MS-DIN-E) at both the ends to hold the
amplifiers between their flat sides.
rTighten the screws to fix the end plates
(MS-DIN-E).
Cascading method
qLoosen the screws of the end plates
(MS-DIN-E).
wRemove the end plates (MS-DIN-E).
eSlide the amplifiers and remove them one
by one.

,OPERATION PROCEDURE
䢇When the power supply is switched on, normal condition is displayed [MODE indi-
cator / RUN (green) lights up] and the digital display shows the incident light inten-
sity.
䢇When MODE key is pressed, the mode changes as per the diagram below. Fur-
ther, if the jog switch is pressed for 3 sec., or more, in ‘ADJ’, ‘DISP’or ‘OUT’con-
dition, SUB mode can be set.

.RUN MODE
䢇When MODE indicator / RUN (green) lights up, the display setting or the sensitiv-
ity select setting can be checked. Refer to ⁄5 SENSITIVITY SELECTION FUNC-
TION for further details of sensitivity select setting.
䢇When cJog switch is pressed for 2 sec., or more, the display changes as per the
diagram below.
How to change to ‘percent display’
䢇If xJog switch is turned to ‘+’or ‘–’side, the present sensitivity state can be
confirmed. After 2 sec., the display returns to ‘digit display’or ‘percent display’.
