Wiring the Relay Output:
The Switch-Tek™ relay output can be wired as a dry contact to a
VDC or VAC power source. Switch-Tek™ does require 12 - 36 VDC
power to operate the sensor and switch the relay. 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).
Switching a Normally Open AC Load:
The Red wire connects to Positive (+) of the DC power supply and the
Black wire connects to Negative (-). The LOAD can be attached to
the Green wire and the Hot of the VAC power. Connect the White to
the Neutral of the VAC power (see illustration below).
Switching a Normally Closed AC Load:
The Black wire connects to Positive (+) of the DC power supply and
the Red wire connects to Negative (-). The LOAD can be attached to
the Green wire and the Hot of the VAC power. Connect the White to
the Neutral of the VAC 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 Yellow 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 Yellow
wire to identify when the Vibration switch requires cleaning.
To wire the maintenance output wire to an LED, follow the wiring dia-
gram below. The Yellow wire is connected to the LED and a 2.2kΩ
resister in series and referenced back to the (+) of the power supply.
To wire the maintenance output wire to an PLC, follow the wiring dia-
gram below. The Yellow wire is connected to the PLC input with a 10
kΩ resister parallel to the PLC input and the (+) of the power supply.
