delay time with which the pumps DOL
start after the variable speed pump has
reached the maximum frequency and
the readen value has fallen below set
value – delta control.
OFF
Function to enable multiple DrivE-Tech’s
to work in parallel as described in the
technical appendix (see the relevant
chapter). Up to 8 DrivE-Tech units can
be connected in parallel.
DrivE-Tech’s communication through RS
485 gates is granted by a private
protocol.

Direct: increasing misured value, DrivE-
Tech decreases motor frequency.
Reverse: increasing misured value,
DrivE-Tech 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.
0.65
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
DrivE-Tech display; a value can be set by
assuming a dry cosphi equivalent to 60%
of the rated cosphi specified by the
manufacturer.
10
Restart delay after a dry running alarm.
At each tentative (max 5) restart delay
will be doubled.
N.O.
By selecting N.A. (normally open)
DrivE-Tech 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)
DrivE-Tech runs the motor if the digital
input 1 is closed; motor will be stopped
if the digital input 1 is opened.
N.O.
By selecting N.A. (normally open)
DrivE-Tech runs the motor if the digital
input 2 is open; motor will be stopped if
the digital input 2 is closed.
By selecting N.C. (normally closed)
DrivE-Tech runs the motor if the digital
input 2 is closed; motor will be stopped
if the digital input 2 is opened.
N.O.
By selecting N.A. (normally open)
DrivE-Tech runs the motor if the digital
input 3 is open; motor will be stopped if
the digital input 3 is closed.
