N/A
There are 3 programmable Aux contacts
available on TB2 of the VMX2 soft start (2
form-C and 1 form-A). The function of these
contacts are labeled on the wiring diagrams,
but can be changed in the VMX2
programming. Note however, that the
contacts may not function properly when
operating in the X-LINE mode. (see
description below).
X-LINE Operation:
VMX-B packages are supplied with a SOFT/X-
LINE selector switch, located on the TCB3000
PCB that allows the operator to select Full
Voltage operation of the motor via the bypass
contactor for emergency operation when the
soft start may be inoperable.
When operated in the X-LINE mode full
start/stop control is maintained, and the “Run
Status Output Contacts” will function correctly.
During X-LINE operation, the motor will be
protected by the external Bi-Metal overload
relay which must be set according to the motor
FLA and the Current transformer ratio of the
unit.
Important:
Motor FLA and Service Factor must be
entered prior to a start attempt see next
section on how to set Motor FLA and
Service Factor parameters.
