Status Indication Three programmable hard contact outputs are provided as standard. The
first two contacts are Form C and programmable for Normal or Up-to-speed.
They must be set for "Up-to-speed" to control the bypass contactor, and for
operating logic on the interface board. The third contact is programmable
as Normal or Fault. For Bulletin 1560D applications, it is set for "Fault" to
signal the line contactor to open in the user's starter feeding the MV Dialog
controller. For Bulletin 1562D applications, it is set for "Normal" to control
the closing and opening of the line contactor. The contact will open if there
is a fault condition.
Control Options The MV Dialog Plus™ controller offers the control options described below.
Important: The options listed in this section are mutually exclusive and
must be specified when ordering. An existing controller may be upgraded
to another control option by replacing the control module and possibly other
components. Consult your nearest Rockwell Automation sales office.
Option maneuvers count as a start when determining thermal capacity of the MV
Dialog Plus. i.e., a soft start followed by a soft stop counts as two starts, and the
unit must have the required rest period before another start (see Note below).
Soft Stop Option
This option can be used in applications that require an extended coast-to-
rest time. The voltage ramp-down time is user-adjustable from 0 to 60
seconds and is adjusted independently from the starting time. The load
will stop when the output voltage drops to a point where the load torque is
greater than the developed motor torque.
Note: Consult factory if settings over 30 seconds are required. The base
rating of the MV Dialog Plus is two starts (or one start/stop combination)
per hour, thirty seconds maximum for each operation. A stopping operation
counts as a start for purposes of thermal capacity calculations.
