Operating Instructions
Do not strike the lamp unless the projector is OFF or in the NOT READY state.
Failure to comply with this procedure could result in damage to the projector or film.
N o r m a l O p e r a t i o n
Apply power by positioning the PROJECTOR ON/OFF switch on the power supply switch panel to
ON
. The frame
counter display should read
01:00:00:00
(one hour). The LED’s on the <NOT RDY>, and <9> buttons should be on. The
shutter will not be rotating at this time. Be sure film is properly mounted and threaded. Enter the film rate at which the
projector is to operate (See Section 2.8.36). Press the <READY> key, and observe the following sequence:
(Refer to the operating commands outlined in Section 2.8.)
1.
The projector performs a loop set and the Pulldown motor system is tested. The LED on the
<SET LOOP> key will go on.
2.
Simultaneously, the brake solenoids release, and the torque arms move into position.
3.
The constant velocity sprocket advances one frame and the CV motor system is tested.
4.
The shutter comes up to speed and is tested.
5.
The <STOP> and <READY> LED’s go on, and the <SET LOOP> LED goes off.
6.
Enter a
CUE
(press <CUE>) command. The film moves forward in slew motion at 15 fps until the BOF tape is
found.
7.
Enter a
SET CURRENT SHOW
(<H>,<5>) command, and indicate which show the projector is cued to (The
default show number is 1.). The projector is now ready for the first show.
If the film length, BOF/EOF markers, or shows have been changed, new show times
must be entered into the projector. First, clear all stored time codes with the CLEAR
CUES command (see Section 2.8.6). Then, enter new cue points by the AUTO LOG
(see Section 2.8.7), MANUAL LOG (see Section 2.8.13), or SHOW CONTROLLER
LOG (see Section 2.8.14) commands, or in DEFAULT LOG mode (Section 2.3.1).
Operation of the projector is automatic:
1.
Enter a
FORWARD
command (press <FOR>) to start.
2.
The douser can be opened by a show controller command by entering an
OPEN DOUSER AND CINE
(<C3>)
command, or automatically if the
AUTO DOUSER
( <G3>) command has been entered.
3.
When the EOF tape is detected, the douser automatically closes, and the film stops. The projector then automatically
cue’s the film so that it is ready for the next show. The projector will not pick up commands from the show
controller until after a
SHOW CONTROL ENABLE
(<G9>) command is entered.
