Setup Procedure
Section 3-1
nel in the group and check that the values are refreshed.
Note
An error will occur if a mixture of gradient temperature control and 2-PID con-
trol is used and GT or AT is executed for all channels. Execute GT or AT for
individual groups if a mixture of gradient temperature and 2-PID control is
used.
10. Start control.
Control is started and canceled for the HFU.
To start control for gradient temperature control groups, first read the sta-
tus of the initial channel in the groups and check that bit 13 (GTC Error) is
OFF (No error) then execute a RUN operation command.
Note
Gradient Temperature Control (GTC) Errors
If the power is interrupted immediately after GT has been complet-
ed or while downloading the HFU parameters using the Support
Software, the internal parameters for GTC will not be refreshed cor-
rectly and control may not be able to be started. Use one of the fol-
lowing methods if this error occurs.
• Re-execute GT.
• Download the parameters again and reset.
• Initialize the setting values and reset.
Example1 : Starting Control for Group 2 (Gradient)
Execute a RUN operation command for channel 5.
Example 2: Starting Control for the Initial Channel in Group 4 (2-PID
Control)
Execute a RUN operation command for channel 13.
Example 3: Starting Control for All Groups
Execute a RUN command with all channels specified.
Note
A RUN command can be executed even for a mixture of gradient
temperature and 2-PID control.
11. Perform Tuning for 2-PID Control.
Tuning for 2-PID control is called autotuning (AT). AT is executed and can-
celed for the HFU.
