Wiring indicator lamp ON (pressure rise) (Fig 3)
To wire the indicator lamp to come "0N" on detecting a pressure rise,
only the B contact is wired in accordance with the diagram shown in
Fig 3.

CAUTION
Two adhesive nameplates are supplied to indicate the above
situations, place the appropriate label on the outside of the unit in a
highly VISIBLE position.
There are (+) AND (-) terminals for connecting a 24VDC power supply.
The red lead wire connects to the (+) terminal and the black lead wire
to the (-) terminal. A LED is fitted to the 24VDC supply. The LEAKAGE
current is 3mA.
Operating a PLC using leakage current (Fig 4)
Directly connect the LED to the power supply as shown in Fig 4.

Internal resistance of the lamp is L1: 33kΩ, L2: 100kΩ, and L5:
8.2kΩ.
Adjustment
Neon lamp lights OFF
by pressure increase
The pressure can be set by turning the adjusting screw, using a small
bladed screwdriver.
