conditions are also activated when the sensor is open. For thermistors, an open
circuit will trigger a low limit, while all other sensors will trigger a high limit.
How the instrument reacts to these limits depends on two settings:
Outoff Settings (TEC:ENABLE:OUTOFF)
Apply Nonactive (TEC:ENABLE:NONACTIVELIMITS)
Apply Nonactive
is used to include the temperature limits of the non-active
primary sensor when determining if a temperature limit condition exists. When
enabled, and the non-active primary sensor is also enabled, a limit condition on
the non-active primary sensor will cause a temperature limit condition. If
disabled, the non-active primary sensor will not be used in determining if a limit
condition exists.
By default,
Apply Nonactive
is disabled, which means only a temperature limit
of the active sensor will cause the temperature to shut down.
Once a determination is made that a temperature limit condition exists, the
settings in the
OUTOFF
register will determine if the output will be shutdown. If
enabled and an appropriate high or low limit condition exists, the output will be
turned off.
In all cases, limits are only applied to enabled sensors. When a sensor is
disabled, it will not be evaluated for limit conditions.
Selecting the Fixture
The
586
TECPak
has integrated support for many of the mounts offered by
Arroyo Instruments, such as the
205 TEC Butterfly
LaserMount
. To simplify
operation when using these mounts, you can use the TEC:MOUNT command to
change the mount type you are using. By selecting a mount, the current limit,
temperature limits, default gain, and sensor settings are automatically adjusted
to values appropriate to the mount, and menu settings limited to the capabilities
of the mount.
