16 ST-133 Controller Manual Version 3.B
Suitable driver electronics will also be required. See the Note on page 20 for
information on how the signal provided at the connector is selected.
REMOTE: The shutter-drive pulses are provided at the Remote connector.
WARNING
:
Dangerous live potentials are present at the Remote Shutter Power
connector. To avoid shock hazard, the Controller power should be OFF when connecting
or disconnecting a remote shutter.
SETTING: The Shutter Setting selector sets the shutter hold
voltage. Each shutter type, whether internal or
external, requires a different setting. Consult the table
below to determine the proper setting for your
shutter. The Shutter Setting dial is correctly set at the
factory for the camera’s internal shutter if one is
present.
Note: With a PI-MAX camera, the setting doesn’t
matter, unless the system includes an external shutter
(typically a slit shutter for spectroscopy) to be powered
from the ST-133. If this is the case, the correct setting
would be "1".

Table 1. Shutter Setting Selection
An incorrect setting may cause the shutter to malfunction or be damaged. Cameras
having a 35 mm shutter, such as an NTE having the 1340 × 1300 CCD, must be used
with an ST-133 having the 70 V shutter option installed (indicated on the back panel as
shown in Figure 2). An ST-133 having this option cannot be used with a camera having
the small (standard) shutter, even by selecting a lower number, because the shutter could
be permanently damaged by the high drive voltage and larger stored energy required to
drive the 70 V shutter.
