6.4 Minimum speed cut off DIP 5
If no
“
n-min
”
is adjusted,output voltage goes continuously with reduction of the regulating
variable down to
“
0
”
(cutoff below approx. 2 % regulating variable).
Without minimum speed cut OFF (DIP 5 =
|
OFF
|
= factory setting)
•
If minimal speed
“
n-min
”
is adjusted (e.g. 20%), then no disconnection of the fan
takes place. I.e. always a minimum ventilation is ensured (fan does not go under
setting
“
n-min
”
).
With minimum speed cut off (DIP 5 =
|
ON
|
)
•
Cutoff below approx. 2 % regulating variable from sestting
“
n-min
”
to
“
0
”
.
•
Switch on again for a regulating variable above 5 % (to setting
“
n-min
”
).

6.5 Hardstart function DIP 6
Special function for motorstart with maximum output voltage.
DIP 6 =
|
OFF
|
“
Hardstart
”
function = OFF (factory setting).
After switching the mains voltage on the output voltage rises during the
fi
rmly
programmed run-up time to the given value.
DIP 6 =
|
ON
|
“
Hardstart
”
function = ON.
For a safe starting of the connected fans the function
“
Hard start
”
can be
activated.
After switching the mains voltage on the controller generates for approx. 10 sec-
onds max. voltage
“
100 %
”
ignoring any control signal.
Afterwards the output voltage adjusts itself to the given value.
6.6 Operation with two variable output voltages (two steps)
DIP2 =
|
OFF
|
for setting via external signall.
Switchover between two steps via external potential-free contact possible.
•
Step 1
(low speed). When there is no input signal connected to the input terminal
“
E1
”
, then the unit supplies the output voltage set by
“
n-min
”
.
•
Step 2
(high speed). When the terminal
“
A1
”
(+10 V) is connected with the input
terminal
“
E1
”
then the units supplies the output voltage set by
“
n-max
”
.
