Multiple or sequential control module
With the function
multiple control module
two or three
drives are operated simultaneously.
In the
sequence control mode
, the drives are connected
in series - depending on the selected sequence control. Here
the shutdown of a drive is the start signal of the next drive.
Post cycle locking
As soon as the
USKM
has switched off the drives and
locking drives in one running direction, it does not permit
any further operation - in this direction.
Only after reversing the polarity of the input voltage - in the
opposite direction - the
USKM
is reactivated.
Cut-off current surveillance
The current consumption of the connected drives and
locking drives is permanently monitored. When the set
value has been exceeded, the
USKM
switches off the
connected motor. If a drive stops, for example, because of a
defected cable, the
USKM
recognizes this as undercurrent.
All connected drives and locking drives are switched OFF.
Switch-off function for drives with internal
load dependent cut-off switch (e.g. OFV1)
These drives switch off by its own, if the current con-
sumption drops below a certain trashold. This state is not
displayed on the
USKM
as an error message.
If the current consumption of the drive exceeds the set
trashold (max. 2,4 A), this is signaled as a fault (the
LED
status display indicates red fast blinks) and all motors
are switched off.

Changing the factory set run-on time of 2
seconds can lead to drive and window case-
ment demage.
For damage - caused by the change of the
run-on time -
A
UMÜLLER
assumes no liability.
Larger screwdriver can lead to mechanical
damage.

The run-on time is the internal switch-off-time set at the
USKM
for the monitoring of the parallel operation of 2 or
3 drives. It determines the misaligment between the
drive-strokes, which results from the multiplication of the
run-on time and the speed of the drives.
The run-on time between the switch-off point of the fi rst
drive - by overload or low voltage - and the forced shut-
down of the other drives in parallel operation, can be set on
the circuit board with a potentiometer
Œ
in the range of
0 to 5 seconds. The factory setting is 2 seconds.
¢
Operate the potentiometer
Œ
with a screwdriver
(size
0
).
The set run-on time can be measured with a stopwatch.
An error must be simulated to a drive output and the time
must be measured in which the other drives operated in
parallel running mode are switched off.
Alternatively, the DC voltage at the two measuring points
MP1 (-)
•
and
MP2 (+)
Ž
has to be measured - with a
digital multimeter - and converted into time according to
the formula
t = V
.
