5.5 Brief description
NCS 11 is used to automatically clean soiled jet valve nozzles.
On the upper side of the cleaning device a cleaning tape rests lightly on a push button.
When the valve nozzle triggers the push button there is mechanical contact. The tape is
then pulled under the nozzle and any residue on the nozzle is removed.
The cleaning device can be operated autonomously or by an external control unit. Settings
include trigger and gate operation, selection of a constant tape length of between 3.5 and
52.5 mm and operation with a constant tape speed.
The tape reel is changed without the need for tools. To this end the entire module is
removed from its base plate and the magnetic side cover removed. Both the empty tape reel
and the soiled tape on its center ring can be removed from their take-up spools and
replaced with new ones.
5.6 Features
Autonomous operation or operation by an external control unit
Autonomous operation: cleans as long as the nozzle triggers the switch or with a
constant tape length
External operation: cleans on a signal pulse (trigger mode) with a constant tape length
or for the duration of the signal (gate mode)
Tape length can be selected for each individual cleaning session
LED lights up and signal output before and on tape end and failure
Remaining tape slit
Fast reel change without the need for tools
Compact design, mounted on a base plate with a 50-mm grid
Configuration using dipswitches
D-sub connection for voltage supply and signal transmission.
9-pole
Firmware update through internal USB interface

13 Status LED
13.1 LED is on
Failure/end of tape: the status LED (C) is permanently on when the drive is active but no
pulse from the encoder has been registered for longer than a stipulated period. Possible
causes are:
Tape end
See chapter 12
Tape incorrectly threaded or
blocked
See chapter 12, step 8
The error is reset by pressing switch A.
13.2 LED flashes slowly
End-of-tape warning: when the amount of remaining tape undershoots the threshold of
approximately 5%, this is signaled by slow flashes from the LED (500 ms on, 2,500 ms off).
This gives advance warning of a pending change of tape reel.
13.3 LED flashes quickly
Constant motor current exceeded: if the motor is run at overload for longer than 30
seconds, the control unit shuts down and sends an error message to the user via quick
flashes of the status LED (500 ms on, 1,000 ms off). Possible causes are:
Mechanical defect
e.g. bearing failure
Tape tension too high
Contact pressure on the push
button too great
The error is reset by pressing switch A.
Max. 1.5 mm
