Ekra E4 stencil wipe problem | 8 September, 2016

Hello, we have an Ekra E4 that we bought used and the stencil wipe never worked. We found that the air tubing for the up (black)& down (blue) of the wipe roll is missing. There are 2 push connectors for up and 2 for down to receive the tubes. Does anyone ave a picture or diagram of which is which? See attached file. There are also 2 large and one small black air tubes. Again does anyone have a picture or diagram?

Thanks in advance for your help.

Thanks to Bobpan we re connected our wipe system and all the air actuators work fine. I still have a problem with the cleaner fluid dispenser. It is not moving as it should to dispense the liquid when we do the command. I suspect the values in the cleaning page are not correct. Can anyonel post a picture of the page or point out wrong values below. Thanks again Cleaning distance out of the PCB width in front 500um-- back 500um-- Vacuum without paper: 1-- WT after set/delete the cleaning bit. 1000 / 500 ms (only with vacuum)-- WT before/after set/delete the vacuum bit: 0 / 500 ms-- WT after set/delete the wet cleaning bit: 0 / 500ms-- Analog value roll diameter minimum. 200 -- AnalogueAnalogue value roll velocity: 45 -- Analog value roll diameter maximum. 1100 -- Analogue value roll velocity: 120 -- SPRINKLER (only cleaning type 2)--- Transmission ratio: 100 steps per 173 um-- Distance from the limit switch to the right: 540000 um-- Analogue value for reference move velocity: 200 (analog value)-- Least velocity while reference move: 5000 um/s (below it abort, because sprinkler jams)-- Time for searching the limit switch to right: 5000 ms (if sprinkler is in left of the switch)-- Do the reference move: [0] (reference move done: 1)-- Zero position: 325500 um from limit switch (middle of PCB)-- Move to zero position: [0]-- Analogue value for velocity level 1: 50-- Analogue value for velocity level 10: 255-- WT after reaching the start position: 0 ms-- WT after setting the wet bit: 0 ms-- WT after reaching the end position: 0 ms-- WT after deleting the wet bit: 100 ms--
