Control Wiring

710-03261-00D
The soft starter's operation can be controlled in three ways:
•
using the buttons on the MVS Controller
•
via remote inputs
•
via a serial communication link
The < LCL/RMT > button controls whether the MVS will respond to local control (via
the MVS Controller) or remote control (via the remote inputs). Serial
communication is always enabled in local control mode, and can be enabled or
disabled in remote control mode (refer to parameter 4-B).
The MVS has three fixed inputs for remote control. These inputs should be
controlled by contacts rated for low voltage, low current operation (gold flash or
similar).

CAUTION
Do not apply voltage to the control input terminals. These are active
24 VDC inputs and must be controlled with potential free circuits.
Ensure cables to the control inputs are segregated from AC power and
control wiring.
CAUTION
The < STOP > button on the MVS Controller is always enabled. When
using two-wire remote control, the soft starter will restart immediately if
the remote start input is still active.
