VSI Series 1000-X Electric Actuator
Operation and Maintenance Manual
2
• Actuators are equipped with an internal overheat protection device.
When the motor exceeds the temperature of 257°F (125°C), the
overheat protection device will automatically switch off the motor.
• Take proper leakage protection steps when installing actuator
and its associated wiring, and when putting it into service. Cables
connected to the actuator conduit entries must utilize proper
waterproof cable ends. Tube conduit should come from below and
up to the actuator to keep fluid from draining into the actuator.
• Confirm input voltages and signal polarity corresponds with those
shown for the actuator’s associated data.
• Only qualified service personnel who are familiar with the
installation, commissioning and operation of the actuator should
perform installation and servicing.
• All actuators have the proper wiring diagram affixed to the inside of
the Front Wiring Cover (#4); all wiring should follow these diagrams.
Do not manually operate the actuator without deenergizing
actuator with factory installed push button or by external
disconnect such as a circuit breaker.
NOTICE
• Valve Solutions, Inc is not responsible for damages incurred because
of modification, lack of proper maintenance, or improper usage of
actuators
To prevent reduced or erratic performance a single
isolated relay is required for each actuator; refer to
diagram.
