TROLL electronic boards
1. Remove the covers (see card Gr7-1 );
2. Unplug jumper X21 of the CPU board;
3. Remove the wirings of the probes PT1...PT4, and connect the ref connector
provided with the pin for the check of value 000,0;
4. Switch-on the unit, enter the SETUP mode, SERVICE menu, enter the
access code “++--++--“, move to the option PT1 CORRECTION, and check
that the PT1 value matches 1500 Ω;
5. Exit SETUP mode, switch-off the unit, then switch-on again maintaining
pressed the Start key; LCD will show the message “SETUP” and then the
PT1 value;
6. Press the first left-side key; the value will decrease at 000,0;
7. Should the value to be different, use key + and – to change the value up to
000,0; wait a few seconds to check its stability;
8. Press the Start key and repeat the check for any PTn as above, adjusting the
value in case of mismatch from 000,0;
9. Push again the Start key to continue the PT calibration with the tests at
130.4; remove the ref connector, and plug-in it again in reverse direction;
10. Push the first left-side key; the value will increase to the new reference value;
11. Push again the first left-side key to approach the reading value; should the
value to be different, use key + and – to increase or decrease the value up to
the reference one; wait a few seconds to check its stability;
12. Push the key Start and repeat the check for any PTn as above, adjusting the
value in case of mismatch;
13. Continue with the MPx calibration at ambient pressure; use the left-side
key to approach the value to the reference one, and the key + to set the
value at 0,00; wait a few seconds to check its stability;
14. Push again the key Start for the MPx calibration at 2,10 bar; connect the
pressure transducer to an external air compressor, set the pressure at 2,10
bar; pushing the first left-side key the read value will approach to the
reference one; use key + and – to increase or decrease the value up to
match the reference one; wait a few seconds to check its stability;
15. Push again the key Start for the MPx calibration at -.90 bar; remove the air
compressor, and connect the pressure transducer to an external vacuum
pump; set the value at -.90 bar; pushing the first left-side key the read value
will approach to the reference one; use key + and – to increase or decrease
the value up to match the reference one; wait a few seconds to check its
stability;
16. Push again the key Start; the display will now show “SETUP COMPLETE”;
push the key Start to confirm, and wait the end of the self-test;
17. Switch-off the unit; remove the sample connector; restore the PTn wirings
and jumper X21;
18. Switch-on the unit, enter the SETUP mode, SERVICE menu, enter the code
“++--++--“, go to PT1 CORRECTION option;
19. Use key + and – to increase or decrease the value up to match the value
written on the label attached on the right rail;
20. Push the key Start to confirm the operation; exit the SETUP mode and
switch-off the unit;
21. Switch-on the unit and perform a sterilization cycle.
