and depends on the lamp age and ambient temperature. When an exposure
at high power is initiated, the lamp voltage rises to the maximum. The
voltage remains there after the lamp returns to low power, until the lamp
temperature again stabilizes.

The shutter voltage is present during the rotation of the shutter.
The shutter motor runs on 120V~ measured to terminal 4.
•
#7
Shutter position DC common (see terminal 9)

#9
The shutter position switch reports the position of the shutter to
the printed circuit board. This switch is open when the shutter is closed,
and closes when the shutter opens. This signal is low voltage DC and
can be measured (+) on terminal 9, (-) on terminal 7. The meter will read
+12 VDC when the shutter is closed, and 0 VDC when the shutter is
opened.
•
#10
Interlock and thermostat switching. During normal operation,
terminal 10 is shorted to terminal 4 (V~ common). An V~ voltage present
would indicate the glass switch or one of the two thermostat switches
open.
•
#11
Not presently used.
•
#12#14
Incoming voltage. To get load voltage, meter between
terminals 12 & 14 while power is on. On 208/240V~ equipment set
voltage selection switch accordingly, (low=219V~ or below, high=220V~
or above).
