4. The motion controller does not work
4.1.1 The controller contains electrical valves, which do not work in a magnetic field. Make sure that the controller is at
least 2 meters (6 feet) away from the magnet dewar cryostat.
4.1.2 Open the motion controller. First loosen the four screws of the cover by two turns counter clockwise each. Now lift up
the cover up as far it goes (the cover may stick to the case, just pull on it). Finally loosen the screws all the way and pull the
cover off.
4.1.3 Switch the motion controller off and on. Observe all LED lights. For the first two seconds, the LED’s are:
green red I green green green green green green
RUN ERR 0 1 2 3 4 5
Orange red
O
green green green green
COM I/O 0 1 2 3
4.1.4 Two seconds after switching on:
Green
I
RUN ERR 0 1 2 3 4 5
O green green
COM I/O 0 1 2 3
Section 1.6
4.1.5 Four seconds after switching on:
Green I
RUN ERR 0 1 2 3 4 5
O green ????
COM I/O 0 1 2 3
4.1.6 If the LED O - 3 is green, then press the RESET switch. The O-3 LED should go off.
4.1.7 If there are no lights, check the power cord and the fuse. There is a spare fuse inside the fuse holder, 250V-3A slow-
blow.
4.1.8 If during the first two seconds some lights are missing, or a red light is still on after two seconds, then the motion
controller unit needs to be replaced.
4.1.9 To check input 0, 1, 2 and 3, blow into the corresponding sensor inputs with a short piece of Ø 4 mm hose (supplied).
I-1 should come on before I-3. To check input 4, press the reset switch.
