INSTALLATION POSITION / DIRECTION / METHOD
●Use the 35mm width DIN rail to install the unit.
●The installation position/direction is not basically limited.
●Please x this product with optional DIN rail stopper MS-DIN-E after it
installs it in 35mm width DIN rail.
●Tighten the wiring to the wiring terminal block at tightening torque of
0.6N·m.
●Please install and connect ferrule (sleeve) terminal when the lead wire
of the connected equipment is a twisted wire. Please do not connect the
twisted wire directly with the terminal.
●Always install this product in a control panel having an IP54 or higher
protective structure.
4I/O CIRCUIT DIAGRAM
* E: Emitter, R: Receiver
T_IN: Used to connect the test input wire (or the emission halt input wire) of light curtain.
A_IN: Used to connect the auxiliary output wire (or the alarm output wire) of light curtain.
Note: Please wire between X1-X2 when using it by the manual reset as shown in the gure
below or please wire between X1-X3 when using it by the auto reset.
WARNING
Install a RESET switch in palace where it is possible to see all over the
dangerous zone and outside of the zone.
5CIRCUIT EXAMPLE
●Wiring example of input part
2-channel input type
Connection of PNP transistor output
It is possible to detect the wire disconnection
and short-circuit (against ground) by the built-in
monitor circuit.
When the external reset signal is connected.
• For auto reset, the external conductor B contact
is connected to between the X1-X3 to make up
a back-check circuit.
When the back-check function is not used, the
jumper is connected to between the X1-X3.
When the external reset button (it makes up a
back-up check circuit between X1-X2.) is used,
the relay unit is operated by the signal trailing
operation. When the product is used for auto-
start, use the other control circuit to prevent the
system (after emergency shutdown) from be-
ing reset automatically. (Refer to the “IEC / EN
60204-1)
• The test input polarity selection switch S1 (ar-
ranged on rear side of upper cover) built in the
relay unit is changed depending on the polarity of
test input (emission halt input).
* It has been set to 'PNP' side at time of ship-
ment.
For SF2-EH series, change the slide switch to
“NPN” side prior to use.
●Connection example of output part
• 1-channel output
The 1-channel output is suitable for the
strengthened type to which a relay is used, or
for the contactor to which chamber structure
type contact or forced guide type contact is pro-
vided.
* The external reset button is connected in se-
ries to the back-check circuit.
• 2-channel output
The 2-channel output is suitable for the
strengthened type to which a relay is used, or
for the contactor to which chamber structure
type contact or forced guide type contact is pro-
vided.
* The external reset button is connected in se-
ries to the back-check circuit.

7SHORT-CIRCUIT PROTECTION
●The power supply unit of this equipment adopts the electronic fuse
which do not require any replacement.
●When the electronic fuse is operated, turn OFF the power supply, and remove
the cause of overcurrent before restarting the power supply for resetting.
●The electronic fuse is not suitable to use in which the equipment is op-
erated continuously or daily. Note that operating the equipment continu-
ously may be unable to satisfy the specications.
8FUNCTIONS
●Trailing edge switching function
• This function is to accept the input when the reset switch is pressed (con-
tact “close”) and then released (contact “open”) at the manual start setting.
An unexpected start-up due to the welded reset switch can be avoided.
●Test input polarity selection function
• The function is used to change the polarity of the test input to PNP or
NPN with an internal switch.
9MAINTENANCE
●Be sure to do maintenance before use and 6 month periodic maintenance.
Refer included instruction manual of light curtain for the inspection items.
●In case replacing this device to new this device, be sure special techni-
cian to exchange it. And do daily maintenance and periodic maintenance.
