unit. The resistance must be below 0.2 Ohm.

Motors and movement mechanisms
Perform a check of the motors and movement mechanisms
before any covers are removed to survey the need for
service.
Check the X, Y, N and rotational movements for slack by
powering on the unit and making it ready for exposure in
the panoramic light service program. The rotator shall stay
fi rmly in position. No noticeable slack shall be present in X,
Y and N directions. For the rotational movement some
minor slack can be allowed, as long as the movement
centers itself to the same position after being lightly pushed
out of position. Tighten the rotational movement belts
(2 pcs) if needed.
Perform a motorized movement test using s2terminal
service command “motortest”. Check that all movements
are done smoothly and without noise. If any problems are
encountered, service the movement mechanism(s) as
needed. Clean away dirt and apply new lubrication. Fasten
loose parts and exchange worn out ones.
Mains power supply cable
Power off the unit and disconnect it from the mains power
supply. Check the condition of the main power supply
cable. Replace the cable if damaged.
Tubehead
Remove the covers around the tubehead. Make sure that
no oil has leaked from the tubehead. Replace the tubehead
if leakages are encountered.
