7. WARNINGS
If electrical actuator’s wiring is damaged, it must be changed by producer company,
certificated service or someone having technical qualification, for preventing any
dangerous conditions. If the product is to be used in outdoor, explosive or in environments
where harmful animals such as mice live, It is necessary that the supply cables and the
connection materials have the appropriate specifications (armor-plated, atex, etc.).
A 4 Amp B type vending machine fuse should be added to the line where the electric
actuator is connected against any short circuit failure.
Every electrical actuator must be supplied with voltage written on it.
Every electrical actuator must be mounted the proper valve according the output
torque written on it.
When it is necessary in some fluid applications, a filter must be used. Because, some
sediments gathered in the valve cause corrosion and forcing the electrical actuator. This
forcing makes difficult to open or close the valve and can damage the electrical actuator.
Before removing the electric actuator from the system, the voltage on it must be cut off.
In case of hand lever reach to the end please do not force it to more turn.
Preventing from any short circuit or open circuit fault, the electrical actuator cables
must not have any damage(twisting, smashing) on them.Moreover, the cable twisting on
the cable entries can cause to moisture or water entrance to the body. To prevent from
this, proper cable diameter must be selected according to the cable entries.
Used cable must have minimum 1 mm2 section.
8. PRODUCT LIFE
Operation times vary depending on the model of electric actuators. Product life is
variable according to the operating conditions of the product such as daily working
time, ambient temperature, humidity, whether the applied voltage is variable or not. The
duty class level of the motors used in our electric actuators is S2. Therefore, if the motors
are to be operated without interruption in AC ON-OFF electric actuators, they should
be operated for a maximum of 30 minutes, then the motor temperature should not be
operated until it reaches the ambient temperature. Periodic maintenance extends product
life.
