SPECIAL MOTOR APPLICATIONS
Multiple Motors
When more than one motor is connected downstream from the
VMX2
Series
starter, the internal electronic overload protection cannot provide
proper protection of the individual motors. Codes require the use of
separate OLRs for each motor, which would need to be external
devices.
In these instances the
VMX2 Series
Overload protection should be
turned off, deferring protection to the separate OLRs. Care should be
taken to ensure that the External OLR is properly wired into the starter
control circuit to facilitate shutdown of the motor.
