3.3. THE MOTOR
The motor takes a load of 0.8A at 12V at an operat-
ing temperature of 200C (680F) under full load.
Accurate speed control has been achieved by the
use of a comparator circuit containing a crystal. The
crystal is located under the small cover on the motor
assembly (see fig. 9 ) and can be changed easily.
The motor will only operate when it is connected to
the camera. Should the operating speed of the motor
fall below the working level, then a warning light on
the side will come on indicating loss of synch
ronisation. This condition applies if the output power
of the battery is low.
3.4 THE BATTERY.
Contained in the battery unit are a) The safety
thermostat to prevent overheating.
b) A negative temperature co-efficient device to
counteract the positive co-efficient of the battery
cells.
This allows the accurate sensing of the battery
voltage at any temperature. The power requirement
for driving the camera is low. The capacity of the
battery is 1.2 Amp-hour at 200C (680F) and this is
approximately equivalent to 720m (2400 ft) of film.
The connections to the battery are from either of the
Jaeger 4-pin sockets. A central Socapex socket is
used in connection with high speed charging.
