desciption
delay time with which the pumps DOL
start after the variable speed pump has
1
reached the maximum frequency and
the readen value has fallen below set
value – delta control.
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
OFF
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.
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
0.65
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.
Restart delay after a dry running alarm.
10
At each tentative (max 5) restart delay
will be doubled.
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.
N.O.
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.
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.
N.O.
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.
By selecting N.A. (normally open)
DrivE-Tech runs the motor if the digital
N.O.
input 3 is open; motor will be stopped if
the digital input 3 is closed.
