Mounting

The valve should be mounted so that the drive rod on the actuator is
within 85° from the vertical line and the motor housing is on top. The
valve actuator's drive rod should be in its highest/innermost position when
it is mounted on the valve.
Fix the actuator to the valve using the connection nut, manual power is
sufficient.

Wiring

The actuator has a connection cable with a connector which is intended
for connection to the bottom of the actuator. There is only one way to plug
in the contact. Be careful not to damage the cable if the connector needs
to be removed from the actuator.
Connect the supply voltage and control signal. If the actuator and control-
ler share a transformer, it is very important to keep the phase separate
from the zero, so the same pole is used as zero for both controller and
actuator, since this is the reference for the control signal.
Red = control signal 0...10 V

Manual manoeuvring

To set the valve position manually, hold down the disengagement button
(A in the picture below) and then turn the knob for manual manoeuvring
(B in the picture below) to the desired position. When the knob is turned
clockwise, the drive rod is pushed outwards and when the knob is turned
anti-clockwise, the drive rod is pulled inwards. We recommend that the
supply voltage is cut before the actuator is set manually.

Position indication

RVAZ4-24A has a clear position indication which is shown on the
knob for manual manoeuvring. There are markings for 0, 25, 50, 75
and 100 % open position.

Automatic calibration

RVAZ4-24A has an automatic calibration function for adjustment of
zero point and stroke in order to adjust the 0...10 V control signal to
the valve. Calibration takes place each time power is connected.

EMC compatibility

This product conforms with the EMC requirements of European
harmonised standards EN60730-1:2000 and EN60730-2-8:2002 and
carries the CE mark.
