Flowline AX18 Switch-Pro - Manual (Page 5)

Step Five
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 col-
lect 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 con-
necting 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 con-
necting 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 preven-
tative 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).
