Setup Procedure
Section 3-1
Note (a) The HFU can control up to 64 channels, but when the maximum
number of enabled channels is a number other than 4, 8, 16, or
32 channels, non-usable channels result as shown in this exam-
ple. This limits the number of controllable channels and connect-
able Units. Refer to Maximum Number of Connectable Units on
page 28 for details.
(b) If the maximum number of enabled channels is changed in the
configuration, the number of channels allocated for each group
and the initial channel for each group may change.
5. Arrange the Sensors.
Arrange the sensors sequentially to maximize the control performance
within gradient temperature control groups.
