Be sure to read before handling. Refer
to pages 16-14-3 to 16-14-4 for Safety
Instructions and Common Precautions
on the products mentioned in this
catalog, and refer to pages 16-1-11 to
16-1-13 for Precautions on every series.
1.
Light assembly for 24 VDC has 2 terminals
and polarity. One is “+” for red load wire and
the other is “–” for black load wire. Light will
not light up if wired incorrectly.
2.
Light ass'y for 24 VDC has 3 mA of current
leakage. Connect the LED directly to the
power supply if the input of the PLC sees the
switch as closed at all times due to leakage.
1.
In the case of using a switch with indicator
light, wire the indicator light per the following:
2.
Please put the enclosed seal of “LAMP LIGHTS
WHEN PRESSURE RISES.” or “LAMP GOES
OUT WHEN PRESSURE RISES.” on the
equipment where it is easy to see.
1.
Allow the space required for maintenance.
Otherwise, maintenance or pressure adjust-
ment cannot be made, since the adjusting
screw is on the top of the body.
2.
Mounting is possible in either horizontal or
vertical orientations.
1.
Turn the adjusting screw on the cover to set
the pressure with a flat head screwdriver.
Fix the screw with locking nut after adjusting.
Hysteresis is a fixed value.
Increase the setting value by turning to “+” (H)
side. Decrease the setting value by turning to
“–” (L) side.
2.
Use a flat head screwdriver to set the
pressure. Then, lock it in place with the lock
nut. Otherwise the set pressure will change.
3.
The hysteresis (the ON-OFF range) is fixed.
4.
Set pressure scale is the value when pressure increases.

For 110 VAC: 1530118-1 220 VAC: 1530118-2
24 VDC: 1530118-5
Able to convert into L1, L2, L5 by changing
each light assembly.
Warning
Caution
1.
Do not use in an environment, where water or
oil is splashed. Because it is the open type
construction. If water or oil were to make an
ingress, the electrical circuit would be
corroded and result in a malfunction or
damage.
2.
Operating fluids are either air or inert gas
exclusively. Never use liquids.
3.
Never use in an environment where flamma-
ble fluid or gas is used.
Use of this product near flammable materials
could cause an explosive situation. This
product is not explosion-proof.
