Maintenance - Controlli MVH56E Instructions Manual

ASSEMBLING
The actuator can be mounted in the positions shown picture below:
It is advisable to use the motorized valve with MVHT spacer, in order
to reduce the actuator working temperature in case of fluids at high
temperatures (approximately > 120° C) in the valve body. For fluids
over 160 °C avoid mounting the actuator in vertical position on the
valve so as to avoid the direct exposure to heat sources.
For further information look at mounting instructions (MVH56E-
MVHE3K_DIM263).

MAINTENANCE

The actuator is maintenance-free.
ACCESSORIES
DMVE
Endpoint Auxiliary Switches
248
Yoke Heater (Suggested when the fluid temperature is
below 0°C)
GMVH Insulation shell for MVH actuators
ELECTRIC CONNECTIONS
Carry out the electrical connections by removing the cover, in com-
pliance with the rules in force.
The actuator is equipped with a 8 poles removable terminal block;
the each pole of the plug is clearly marked and the same label are
reported on the electric board. Before powering up the actuator
make sure the plug is properly connected to the board and the label
on the plugs and on the board match.
