2. Installation
2.1. RS-1000PA-24V/ RS-1000FA-24V(1) Place the Bracket of the Detection Unit on the surface where you want to detect theleakage, and fix it firmly.
(2) Place a piece of the Absorbent Paper onto the Bracket.
NOTE： Be aware not to use 2 or more pieces of the Paper at a time in the Bracket.
(3) To mount the body, push it into the Bracket to the bottom completely.
NOTE： Verify that the Body has fixed entirely and it does not hook up at intermediateheight in the Bracket.

3. Wiring Instruction(1) The Detection Unit has a 3-core shielded cable, 2 or 1.5 meters long. When the cableneeds to be extended, do not exceed a maximum length of 30m for compliance with CE
Mark.
Red: +5 to 24VDC power
White : Output 1 (No Liquid-ON)Yellow : Output 2 (Liquid Existing-ON)
Shield : 0V power(2) Connect the correct power source to red and shield leads.
CAUTION: Avoid wrong wiring for DC power. (Red line for PLUS polarity, and Shield linefor MINUS.)(3) Keep the load current not to exceed 50mA. Unless, the output circuit of the sensor may
be destroyed.
NOTE: When you apply a relay as a load, add a diode into output connection in parallel
configuration in order to limit the back electromotive voltage. Refer to thediagram below.

When one of the output lines is not used, it will be recommended to connect with 0V firmly foravoiding unexpected shortage with the red lead by an unconnected free lead end.
NOTE: Don’t make any lines be electrically shorted with other lines when the power isapplied. Damages may occur on the sensor.

54. Operation and Function Pre-CheckWARNING： The following procedure must be implemented after wiring has completed and prior toactual operation in the application.

4.1. RS-1000PA-24V/ RS-1000FA-24V(1) Place an Absorbent Paper and Detection Unit into the Bracket properly (Follow theprocedure describing in section 2. Installation.)(2) In this condition, the sensor should be on normal condition. Make sure the following
appearance and status of the Detection Unit:
a. LED on Detection Unit: lit in Green, andb. Signal out through Output 1 (white lead): ON, and/or
c. Signal out through Output 2 ( yellow lead): OFF(3) Remove an Absorbent Paper from the Bracket and place the Body directly on theBracket.
(Note: This is a wrong installation manner. Allowed for test purpose only.)(4) In this condition, the sensor functions even if it detects leakage.
following appearance and status of the Detection Unit:Make sure thea. LED on Detection Unit: lit in Red, andb. Signal out: through Output 1 (yellow lead) OFF, and/or
c. Signal out through Output 2 (white lead) ON(5) Place an Absorbent Paper back in its original place. Now the procedure is completed.

4.2. RS-1000PAP/ RS-1000FAP(1) Place the Detection Unit in to Bracket properly (Follow the procedure describing insection 2. Installation.)
NOTE: Do not use any Absorbent Paper.

(2) In this condition, the sensor should be on normal condition. Make sure the following
appearance and status of the Detection Unit:
a. LED on Detection Unit: Green, andb. Signal out: through Output 1 (white lead) ON, and/or
c. Signal out through Output 2 (yellow lead) OFF(3) Drip the test liquid, such as harmless pure water, at the bottom of the Detection Unit.
(4) In this condition, the sensor will detect the liquid. Make sure the following appearanceand status of the Detection Unit:
a. LED on Detection Unit: lit in Red, andb. Signal out through Output 1 (white lead) OFF, and/orc. Signal out: through Output 2 (yellow lead) ON(5) Wipe the liquid off around the bottom of the sensor. Then the procedure is completed.
NOTE: The periodical check is recommended as following your factory protocol or regulations ofmaintenance plan, but more than at least annually.

NOTE: The liquid detecting device in the Detection Unit is photoelectric sensitive device. When theDetection Unit receives a strong light from outside of the sensor Body (larger than 1,000lxs), it
6 liquid at the sensor from time to time. We
may cause malfunction of detecting the leak7
recommend you to confirm that no such a strong light emitting instrument may not be locatedat close position to Detection Unit, or to place a screen avoiding the light may reach to theDetection Unit. The normal room lighting instrument may not effect the Detection Unit.

5. Resetting after the Leak Detection
WARNING ： The liquid at the use point may contain hazardous acids, alkalis, or
chemical substances. The following procedure has to be done by awell-trained person who is knowledgeable for that liquid.
NOTE： The protection gloves must be put on.
NOTE： In case of handling any chemicals that are obliged to wear the protection
goggles, masks, etc. by regulation, you must follow the regulation.

5.1. RS-1000PA-24V/ RS-1000FA-24V(1) Remove Detection Unit from the Bracket and wipe the bottom clearly.
(2) Remove a wetted Absorbent Paper and wipe the Bracket and its surroundings.
(3) Install a new Absorbent Paper and place a Detection Unit in to the Bracket properly.
(4) Follow the section 4.1 (2) through (5) in this manual.

5.2. RS-1000PAP/ RS-1000FAP(1) Remove a Detection Unit from the Bracket and wipe both of the Detection Unit and theBracket clearly.
(2) Install a Detection Unit back in to the Bracket properly.
NOTE: Do not apply any Absorbent Paper.

(3) Follow the section 4.2 (2) through (5)in this manual
NOTE： The periodical check is recommended as following your factory protocol orregulations of maintenance plan, but more than at least annually.
WARNING： The Sensor is not designed explosion proof. Do not use in the hazardous
area. For this category of UL standard does not allow to use in hazardous
area, and UL does not evaluate for explosive circumstances.
