(a) When safety is the main issue, position the lamp at the point where no more movement is to
be physically allowed.
(b) Set the mechanical hard stop to be in contact with the hard stop travel nut as instructed in the
relevant azimuth and/or elevation setup instructions.
(c) Lamp travel will now be reduced by approximately 9° in elevation as shown in Chapter 4, K,

(a) When the envelope setup is the issue, the lamp should be positioned past the actual required
position so that when the hard stop is brought into contact with the hard stop travel nut and
an initialisation is carried out, the lamp will then be made to stop at the required, earlier
position.
CAUTION:
THE TRAVEL LIMIT POSITIONS FOR ELEVATION ARE DETERMINED BY
THE POSITIONING OF THE MECHANICAL HARD STOPS DURING
SETUP.
NOTE: For first delivery, the travel hard stop positions are set to 190° at the factory
prior to delivery but may be changed, if required, using the following
procedure. Minimum and maximum values of Table 19 have to be considered.
