Function to enable multiple VASCO
Solar
’s to work in parallel as
described in the technical appendix
(see the relevant chapter). Up to 8
VASCO Solar units can be connected
in parallel.
VASCO Solar
’s communication
through RS 485 gates is granted by a
private protocol.

Direct: increasing measured value,
VASCO Solar decreases motor
frequency.
Reverse: increasing measured value,
VASCO Solar increase motor
frequency.

If, during the test, the motor runs in
reverse, it is possible to change the
wiring sequence via software
without physically changing wires at
the terminals.

If the pump goes into dry-running,
the cosphi reaches its lowest level.
To set this value, contact the pump
manufacturer or test by closing the
suction and checking the value on
the VASCO Solar display; a value can
be set by assuming a dry cosphi
equivalent to 60% of the rated
cosphi specified by the
manufacturer.

N.O.
By selecting N.A. (normally open)
VASCO Solar runs the motor if the
digital input 1 is open; motor will
be stopped if the digital input 1 is
closed.
By selecting N.C. (normally closed)
VASCO Solar runs the motor if the
digital input 1 is closed; motor will
be stopped if the digital input 1 is
opened.
