SAFETY PRECAUTIONS

About this Manual: PLEASE READ THE ENTIRE MAN-

UAL PRIOR TO INSTALLING OR USING THIS PRODUCT.
This manual includes information on the Switch Pro™ with
Compact Junction Box: AU15-_13_ and AZ18-113_. The units
are identical except for the material of construction and the
sensors technology.

User's Responsibility for Safety: Flowline manufactures

a wide range of liquid level sensors, controllers, and mounting sys­tems. It is the user's responsibility to select components that are
appropriate for the application, install them properly, perform tests
of the installed system, and maintain all components. The failure to
do so could result in property damage or serious injury.

Proper Installation and Handling: Use a proper sealant

with all installations. Never overtighten the components. Always
check for leaks prior to system start-up.

Material Compatibility:

Polypropylene (PP, a polyolefin): Sensor, Junction Box.
Perfluoroalkoxy (PFA, Teflon®): Sensor (AU15-213_ only).
Ryton (glass filled): Vibration Sensor Only.

Make sure that the application liquids are compatible with the
materials that will be wetted. To determine the chemical compati­bility between the components and its application liquids, refer to
the Compass Corrosion Guide, available from Compass
Publications (phone [phone]).

Temperature and Pressure: Switch Pro™ is designed for

use in application temperatures up to 90° C (194° F). The Vibration
and Ultrasonic packages are designed for pressurized applications
up to 150 psi (10 bar).

Wiring and Electrical: Electrical wiring of any liquid level

control system should be performed in accordance with all applic­able national, state, and local codes. Take care not to cut or break
the outer insulation jacket of wiring that may be immersed while
routing cables in the Switch Pro™ system. Such breaks of the liq­uid seal of the sensor system may lead to component failure.

Flammable, Explosive and Hazardous Applications:

Switch Pro™ may be used within flammable or explosive applica­tions only if the associated components are rated intrinsically safe
for such use. In hazardous applications, use redundant measurement
and control points, each having a different sensing technology.

Make a Fail-Safe System: Design a fail-safe system that

accommodates the possibility of system or power failure. In criti­cal applications, Flowline recommends the use of redundant back­up systems and alarms in addition to the primary system.

About Switch Pro™: Flowline’s Switch Pro™ with Compact

Junction Box Assembly is an single-point mounting system for
installing one level sensor horizontally within a tank. The compact
junction box features termination for the various wires from each level
switch as well as a 1/2” conduit connection. Switch Pro™ mounts hor­izontally through a standard 3/4" NPT fitting.

Level Switches: Switch Pro™ includes

a single level switch used to identify it’s own
unique wet / dry condition. The technologies
used to indicate level are either Ultrasonic or
Vibration. Each technology features a unique
wiring/power configuration (Ultrasonic and
Vibration technologies require 12 to 36 VDC
power for operation, see below). The switch
is terminated in the Compact Junction Box.
The Compact Junction Box provides a 1/2”
Conduit connection and 6 poles for wire ter­mination.

INSTALLATION

Through Wall Installation: Flowline’s Switch-Pro™ A_1_

Series may be installed through the side wall of a tank. The sensor
has male 3/4" NPT (3/4” G) threads on one side of a 15/16" wrench
flat. This enables the user to select the sensor’s mounting orientation,
installed outside of the tank in.

Ultrasonic Orientation: Install the switch such that the gap is

aligned up and down, allowing for liquid to easily leave the gap.
Avoid aligning the gap horizontally. This could allow material to col­lect on one of the flat surfaces in the gap. See the illustrations below
for further information.

Vibration Orientation: Install the switch such that the forks are

aligned up and down, allowing for liquid to easily leave the space
between the forks. Avoid aligning the gap horizontally. This could
allow material to collect on one of the forks. See the illustrations
below for further information.

Do not squeeze the forks together. Doing so could damage or
break the sensor and void the warranty.

Ultrasonic and Vibration Switches

(LU10-1305, LU10-1325, LZ12-1405, LZ12-1425):

The LU10-13_5 and LZ12-14_5 switch can be wired normally open
or normally closed for your application requirement. Each switch
requires 12 - 36 VDC power to operate the sensor and switch the
relay. The relay output can be wired as a dry contact. All illustrations
below identify a Dry switch state as the normal position of the relay.

Switching a Normally Open DC Load:

The Red wire connects to Positive (+) of the power supply and the
Black wire connects to Negative (-). The LOAD can be attached to
either the Green or White wires. Complete the circuit by either con­necting the Green to (+) VDC power or White to (-) VDC power (see
illustration below).

Switching a Normally Closed DC Load:

The Black wire connects to Positive (+) of the power supply and the
Red wire connects to Negative (-). The LOAD can be attached to
either the Green or White wires. Complete the circuit by either con­necting the Green to (+) VDC power or White to (-) VDC power (see
illustration below).

Maintenance Alarm (LZ12 Vibration only):

For optimum performance and proactive maintenance, the sensor
automatically adjusts for coating, and if necessary, outputs a preven­tative maintenance alarm. The Orange wire is a NPN transistor
designed to switch when a build-up of material prevents the vibration
switch from operating at its operational frequency. Use the Orange
wire to identify when the Vibration switch requires cleaning (see the
LZ12 manual for wiring information).

Step Seven Step Eight

MAINTENANCE

General: The Switch Pro™ with Compact Junction Box requires

no periodic maintenance except cleaning as required. It is the respon­sibility of the user to determine the appropriate maintenance schedule,
based on the specific characteristics of the application liquids.

Cleaning Procedure:

1. Power: Make Sure that all power to the sensor, controller and/or

power supply is completely disconnected.

2. Sensor Removal: Make sure that the tank is in a state where it

is safe to remove the sensors. Carefully, remove the Switch Pro™
from the installation.

3. Cleaning the Sensor: Use a soft bristle brush and mild deter-

gent, carefully wash the Switch Pro™. Do not use harsh abrasives
such as steel wool or sandpaper, which might damage the surface
sensor. Do not use incompatible solvents which may damage the
sensor's PP or Ryton plastic body.

4. Sensor Installation: Follow the appropriate steps of installa-

tion as outlined in the installation section of this manual.

Testing the installation:

1. Power: Turn on power to the switches and/or power supply.

2. Immersing the switch: Immerse the sensing tip of each switch

in its application liquid, by filling the tank up to the switches point
of actuation. An alternate method of immersing the switch during
preliminary testing is to hold a cup filled with application liquid
up to the switch's tip.

3. Test: With the switch being fluctuated between wet and dry

states, the switch will open or close depending on wiring status.
If the system doesn't have an input indicator, use a multimeter to
ensure that the switch produces the correct signal.

Current Test (Ultrasonic and Vibration only):

Used to verify if the sensor is indicating a wet or dry condition. This
test uses only two wires (Red and Black). The sensor draws 5 mA
(ultrasonic) or 8 mA (vibration) when it is dry, and 19 mA when wet.
The White and Green wires are not used.
