Installation and commissioning of the electropneumatic actuators must be
carried out in accordance with instrumentation professional standards, and
in particular:
Warnings
CAUTION !
Piping:
When commissioning a new or modified installation, the piping must be
blown through before connecting the actuator in order to clear the circuit
of any impurities, which cannot be avoided during construction (iron filings,
scale, Teflon, welding flux, etc.).
Electric wiring: The power supply voltage and the value of the control
signal must be chec- ked before final connection.
SMARTRONIC MA box:
The covers and housings of the unit must be properly closed to protect the
contents from humidity and, generally, from the outer atmosphere
(”aggressive” atmosphere, dust, etc.) and any incidents which could
damage the internal parts.
Connection by cable gland:
When the electric connection is made through a cable gland, make sure
that:
- the cable gland is suitable for the cable diameter
- the cable gland is correctly tightened on the cable
The pneumatic connection must be provided according to the product specification.
(see IV - I Pneumatic connection)
Never exceed the values indicated in this manual!
This box is an electrical device which contains pressurized gas components. As such, it may be a source of
danger for property or even personnel. Exceeding the values indicated could result in damage.
Never uncouple or dismantle the SMARTRONIC MA box or its accessories when pressurised or
powered up.
Always make sure that the actuator and positioner reservoirs are decompressed before dismantling the dis-
tributor, its solenoid valves or the unit itself.
Also, always check that the power supply is disconnected from its source before any dismantling.
During checks in the workshop or on site, the valve associated with the actuator and positioner must
be operated from fully open to fully closed.
This operation could present a very high risk of injury unless minimum safety measures are taken to
prevent access between the disc and the seat.
