Specifications
16 ST-133/ST-133A Controller Manual Version 2.H
If the camera is equipped with an internal shutter, then the Shutter Power connector
should not be used to drive an external (second) shutter. This configuration will result in
under-powering both shutters and may cause damage to the system. In a system that
requires both an internal and an external shutter, use the TTL
Shutter Monitor
signal,
provided as the default output at the
connector, to control the external shutter.
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 or ST-133A. If this is the
case, the correct setting would be “1.”
