- * change a cable on the top of the magnet under the aluminium cyclinder |
- * change the configuration of the IPS, (Test 07): |
+ * on the top of the magnet under the aluminium cyclinder: |
+ ** make sure that the magnetic field is zero (IPS: shown current is 0 AND "persistent mode" LED is off) |
+ ** switch the magnet power supply IPS off |
+ ** open the cap using the screws marked on the picture above |
+ ** switch the cable from the SYM pin to ASY pin (or vice versa) |
+ ** the cable connected to the COM pin must always stay connected |
+ ** close the cap |
+ ** switch the magnet power supply on |
+ * change the configuration of the IPS: |
+ ** press RAISE+LOWER+LOC/REM simultanously ("tESt" and "t 00" appears) |
+ ** press LOWER to go to "t 07", and then LOC/REM (""SUP" and "S 00" appears) |
+ ** press LOWER 5 times to go to "S 11" and then press LOC/REM (the induction value appears) |
+ ** press and hold LOC/REM and change the value with RAISE or LOWER, release LOC/REM when done |
+ ** press RAISE 7 times to go to "S 02" and then press LOC/REM (the value for max. current appears) |
+ ** press and hold LOC/REM and change the value with RAISE or LOWER, release LOC/REM when done |
+ ** press LOWER once to go to "S 01" and then press LOC/REM (the value for max. current appears) |
+ ** press LOC/REM again (the value for max. field appears) |
+ ** press and hold LOC/REM and change the value with RAISE or LOWER, release LOC/REM when done |
+ ** press LOWER once to go to "S 00" and then press LOC/REM ("tESt" and "t 00" appears) |
+ ** press LOC/REM again ("Stor.y" appears) and again |
