INSTALLATION POSITION / DIRECTION / METHOD
● Use the 35mm width DIN rail to install the unit.
● The installation position/direction is not basically limited.
● Please fix 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.

I/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 figure
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.

CIRCUIT 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.
