Interface Output for running/stopping
the Single Lub 2.
Energizing the Relay R1 will start the
device. (Relay contact 11-14 closes)
De-energizing the Relay R1 will stop the
device. (Relay contact 11-14 opens)
User proper Relais operating voltage and
current type (DC/AC) to meet the
interface output capabilities.

fault
Interface Input for stopping the
spindle in case of fault detected by
the Single Lub 2.
In case of normal operation of the Single
Lub 2, Relay R2 is energized and contact
between I1 and I2 is closed (Relay
contact 11-14 closes)
In case of a fault has been detected,
Relay R2 is de-energized and contact
between I1 and I2 is open (Relay contact
11-14 opens)

In case of non-constant winding speed,
this speed clock signal (0V-24V p-p) can
control the Lube rate if necessary
