FUNCTIONS
Polarity selection function
This is the function to switch either plus grounding or minus grounding with the
polarity selection switch. When the polarity selection switch is set to 'PNP'
side, minus grounding is selected and the connected light curtain SF4B series
is set as PNP output type. When the polarity selection switch is set to 'NPN'
5
Ū
side, plus grounding is selected and the connected light curtain SF4B series is
set as NPN output type.
Since two light curtain input polarity selection switches are equipped, be sure
to set them to the same side.
Trailing edge switching function
This function is to accept the input when the reset switch is pressed (contact
'close') and then released (contact 'open') at the manual start setting.
Ū
CAUTIONS
An unexpected start-up due to the welded reset switch can be avoided.

Make sure to carry out the wiring in the power supply off condition.
٨٨٨
Take care that wrong wiring will damage the product.
Verify that the supply voltage variation is within the rating. Take care that if a
voltage exceeding the rated range is applied, or if an AC power supply is di-
rectly connected, the unit may get burnt or damaged.
The DC power supply unit must satisfy the conditions given below:
1) Power supply unit authorized in the region where this device is to be used.
٨
(In case CE conformity is required.)
2) Power supply unit conforming to EMC Directive and Low-voltage Directive
3) Power supply unit conforming to the Low-voltage Directive and with an out-
put of 100VA or less.

The frame ground (F.G.) terminal must be connected to ground when using
4)
5) Power supply unit with an output holding time of 20ms or more.
6) Use an isolation transformer for the DC power supply unit.
7) In case a surge is generated, take countermeasures such as connecting a
surge absorber to the origin of the surge.
Power supply unit corresponding to CLASS 2 (In case C-UL conformity is required.)
8)
<Additional information>
As proved in IEC 60536 (CLASS: Protection against Electric Shook), this
power supply should require no ground earth and satisfy the insulation dis-
tance called double insulation or reinforced insulation.
In case the power supply conforms to Low-voltage Directive and has an
output of 100VA or less, it can be used as a suitable product.
Do not run the wires together with high-voltage lines or power lines or put
them in the same raceway. This can cause malfunction due to induction.
٨
Avoid dust, dirt, and steam.
Take care that the product does not come in direct contact with oil, grease, or
٨
٨
organic solvents, such as, thinner, etc.
Note that this equipment is applicable only in the control circuit grounded in
٨
accordance with IEC 60204-1 and JIS B 9960-1, or in the control circuit in
which the insulation monitor unit (ground fault detection unit) is arranged.
