Adjustment of the mirror stop
To adjust the mirror of your Varyscan
® 1200 HMI, proceed as follows:
Adjust the initialisation mode at DIP - switch No.1 (DIP -switch position see page 7) and start your
Varyscan
® . Now wait until the initialisation of the scan is ran through and all motors stopped. Then
loosen screw No.1 Now turn the holder for the y-
motor towards the stop up to a distance of 0,5
mm. Tighten screw No.1 now. During tightening
the screw pay attention to the correct adjustment
of the motor brake (see sketch below). Loosen
screw No.2 and turn the y-motor towards the
holder for the y-motor and adjust hereby a
distance of 0,5 mm between the stop and the
holder for the y-motor.
Adjustment of the motor brake
The motor brake is similar at each of the stepper
motors of the scan. There are three special parts
(part no. 2,3 and 4) which must be installed in the
following succession:
Part no. 1. motor
Part no. 2. Tellerfedern
Part no. 3. Stahllaserteil
Part no. 4. Kunststoffscheibe
Part no. 5. zu montierendes Teil
Part no. 5 has to be pushed on the axis of the stepper motor until
the parts no. 2 can not be compressed anymore. After remove the
part no. 5 about 0,5 mm and turn the fastening screws. The "motor-
brake" is now optimum adjusted .
