Technotrans

Does someone know where the temperature is measured of the radiator. When the setpoint is almost reached (.5 degrees before) the fan comes in and doesn't go off.
If I increase the setpoint the fan will go off until the new setpoint is almost reached.

The device is functioning well. The temperature is going from 22.8 to 23.2 (setpoint = 23) I can hear a valve switch when the temp. reached 23.1 and switch of by 22.9, but the fan will blow all the time.

 

The condenser fan will run whilst the refrigeration unit is operating but on some models, particularly those with two fans, one fan will cycle to maintain liquid refrigerant pressure to the expansion valve. Once the set temperature is reached, the condenser fan should stop.

 

I am a UK based refrigeration engineer with quite a lot of experience on various Technotrans machines, particularly Technotrans service. If there is anything I can do to help, just ask.

 

What sparkatan said...

 

I assume the fan only starts to run when the temp. comes above a certain level. As paul stated in a previous post that one cause could be to much dust in the system ( mine is clean ) I think there must be a temp. sensor somewhere that triggers the fan to start. Can someone point me in the right direction.

 

Hi Marc, i don't know if you have already solved the problem, if you need help tell me the type of technotrans unit (for example Beta.C 200L or FTR-C 16000L or FKT-C 25000L) and the year (bj). I know very very well all the Technotrans units.

 

Hi, I currently have an FKT-C model 1996, the temperature shown on the technotrans panel is not transferred to the printing machine screen where it is stuck on 11.6 degrees while it is actually 10, and the alcohol level isnt showing on the technotrans and stuck on 17 on the printing machine display. Moreover do you know by any chance where i can download an english manual for that specific technotrans. Thanks in advance

 

Hi, I think that the technotrans display has lost its parameters and loaded the standard parameters. You must open the back cover of the display, in the upper left you find 8 dip switch, raises the n° 1, look in front of the display and hold the button in the lower right corner for about 5 seconds, a new page will appear, press once the same button and you will find a page with DB parameters and M20 parameters, to show the alcool put M20.0 from 0 to 1 (use arrows and enter buttons), to show the values you must set the DB13: 0 for heidelberg, 202 for man roland, 237 for kba. Now you must switch off then switch on the technotrans and printing machine.
This could be a solution. Good job.
(sorry for my english)

 

Ye i ran through all those but didnt know what exactly to do.. Thank u, will try ur paremeters in the morning n get back to u
Fo u know by any chance where to download an english service manual ?

 

Hi im running a 1998 komori L540, technotrans not dosing alcohol, cleaned out spray power from bottom of alcohol cylinder, but fault screen says 'Alcohol Limiter Valve', any ideas how to reset as solenoid has stuck in the past, i would like to do it myself first before calling an engineer
Thanks in advance

 

Hi Sparkatan, I have a problem with our Technotrans on a Presstek 52di.

Suddenly and error came up while printing.

At the moment the Technotrans doesnt start, the fan, pumps all off. The temperature is showing 30 degrees and should be 20 degrees. The pressure seems correct when off and on.

I have tested and all power to each device is working when a manually press on each relay, I can see the fan turn on, the pump, pressure valves etc...

Also checked the three fuses and they are fine.

Here is a photo of something that I am not sure if its normal. But the LED here is off.

Hope u can help or advise on something I could try. Thanks

 

Just to update: we cleaned the radiator and fan from the dust and everything started to work again. Must have been some sensor.

 

I have technotrans beta c SelectCompiCenter.
Can you help me to fix the problem?
I can't erase the error 122. I need level 3 pw to erase this error
Thanks in advance

Error 018, illegal reset, can i reinstall the software in Technotrans panel ?

 

Hi I have problem with my Technotrans beta c
127 Stepping motor error

Error in the stepping motor of the refrigerant control valve (due to short- circuit, earth fault).

The refrigeration unit is switched off.
