PUSHBUTTON / PILOT
DESCRIPTION
[SOFT STARTER
READY] Pilot Light
Colour White. When no faults occur, it will turn on indicating the user that the equipment is
ready to start.
[SOFT STARTER
RUNNING] Pilot Light
Colour Green. Turned on shows the soft starter is running, that means the bypass
contactor is connected. The moment the soft starter is not running, the light would turn off.
[SOFT STARTER
STOPPED] Pilot Light
Colour Red. Unlike the previous light, when turned on in a continuous way, indicates the
soft starter is stopped. Starting the soft starter, it will turn off.
[POWER SUPPLY
CONNECTED] Pilot Light
Colour Red. Active when the auxiliary low voltage power supply is connected.
[START] Button
Colour Green. The user can start the soft starter in local mode by pressing this button. To
enable it, the user should previously place the control mode selector to the LOC position,
either in soft or direct start, whenever the parameter [G6.1CONTROL MODE] has been
set as [REMOTE].
[STOP] Button
Colour Red. The user is able to stop the soft starter locally. Unlike the start button, it is
always enabled. To enable it, the user should previously place the control mode selector
to the LOC position, either in soft or direct start, whenever the parameter [G6.1CONTROL
MODE] has been set as [REMOTE].
[FAULT ALARM] Pilot
Light
Colour Red. This pilot will turn on when a fault occurs. It emits both an acoustic alarm, by
the use of a buzzer and a light alarm, by the use of a blinking red coloured light.
[EMERGENCY STOP]
Mushroom Button
Emergency red Stop Pushbutton with a rotator lock to sign the emergency stop. When the
motor is running and the button is pressed, the VS65 opens the bypass contactor,
stopping the motor by coasting. If the motor is stopped and the button is pressed, the
VS65 cannot initialize the start sequence. Once the causes which had caused them to be
pressed have disappeared, unlock the button and the VS65 will be ready to start.

Front and rear doors
The VS65 SS is divided in 4 independent sections that prevent the user for unexpected access to
medium voltage active conductors. Additionally, the SS is equipped with explosion proof cabinet and
door locks that minimize the damage for adjoining components in case of explosion.
The soft starter has electromagnetic door opening control designed to avoid medium voltage work risks.
The door opening control is located in the front of the cabinet. This control can only be used when there
is not dangerous voltage in the cabinet. “Power” led shows that there is low voltage in the equipment. L1,
L2 and L3 leds show that there is medium voltage in the equipment. Push the handle button and turn
right to open it. “Open” led will be turned ON while the door is opened.
If the handle is broken or locked, the SS is built in an emergency opening system. The two orifices
situated at the right of the handle allow the access to two screws that open the door.
The door opening control of the rear door can only open the equipment if the front door is opened. Push
the handle button and turn right to open it.
