SDC 2002
5. Operation
5-3
Operating Instructions - Rev. 1 / 6.2003
5.2. AUTOMATIC SWITCHING-OFF
The film scanner includes three automatic switching-off functions.
1. Film end switching-off
2. Film break switching-off
3. Thermal switching-off
5.2.1. FILM END SWITCHING-OFF
In the Play or Play mode, the film is spooled out completely and the film drive
is stopped automatically when the end of film is reached.
In the Shtl
or Shtl mode, the film speed is reduced from maximum to normal
speed and then stopped when the end of film is reached.
Pressing the Shtl key once more spools the film out completely and the film drive is
stopped automatically.
The end-of-film switching-off function is enabled again by pressing the Stop key on
the film deck panel.
5.2.2. FILM BREAK SWITCHING-OFF
In the Play
, Play and Shtl or Shtl modes, the film drive is stopped imme-
diately in case of a film break.
After a short time, the pilot light of the Standby key on the Local Control Panel goes
out and the Stop key lamp on the control panel flashes.
The FPN correction is preserved, the last picture is not frozen.
5.2.3. Thermal switching off
To avoid overheating problems caused by to high a temperature of outgoing cooling
air, a thermal switch is installed into the SDC 2002.
The mains voltage will be switched off by means of this sensor when the exhaust air
exceeds a temperature of 55°C ± 4°C (131
o
F ± 39
o
F).
Thomson guarantees SDC 2002 operation at an ambient temperature of maximum
35°C (95
o
F). The temperature of the exhaust air is normally by 10°C (50
o
F) higher
than the intake air. If the ambient temperature rises up to 40°C (104
o
F) and higher,
damage to a running SDC 2002 is possible.
In such a case the machine is disconnected from the mains and further operation is
only possible after the ambient temperature was reduced.
The thermal switch is performed with a hold function and the mains voltage can only
be switched on via a reset button of this switch (see figure 501: ).
In case the SDC2001 cannot be repowered:
Set the power switch in position ”off
Open the rear doors
Check the power connection to the SDC 2002:
- Mains voltages at the Mains Terminal Board FH 1031 (FH 1033)
- 3 (2) phase circuit breaker
Push the reset button of the internal SDC 2002 thermal switch (figure 501: ).
