■
Connection Precautions
Node Number Setting
Nodes 0 to 31 can be used for HFUs and Basic Units.
Restrictions on the Number of Units
that Can Be Connected
Restrictions for HFUs
•
One EJ1G-HFU can manage up to 16 Basic Units (EJ1G-TC4/
TC2).
•
Up to 16 Units can be connected side by side including the EJ1G-
HFU. The End Unit is not included in the 16 Units.
Note:
When performing gradient temperature control, the number of
control channels is limited by the group setting. For details,
refer to
“Gradient Group Settings”
on page 11.
Restrictions When Connecting with the
G3ZA
•
Up to 8 G3ZA Multi-channel Power Controllers can be connected to
one Basic Unit (EJ1G-TC4/TC2).
Wiring for Distributed Placement
Note:
Wire the dotted line when settings for all EJ1G are being made
from one port A connector.
If the dotted lines are not wired, settings for group A must be
made using the port A connector and settings for group B must
be made using the port A connector.
Restrictions on Unit Placement
Always connect the HFU on the left side of the Basic Unit.
