Preparation
Before commissioning, execute the fluidic and electrical installations.
Connect the HART hand terminal via the 2-pole communication line to the SIDE Control. Attach the
communication lines parallel to the setpoint standard signal. Correct polarity must not be observed.
Supply the SIDE Control with pneumatic auxiliary energy (inlet air) and apply a setpoint
≥ 4 mA.
Switch on the hand terminal with the I/O key: the display shows for a few seconds a self-test
message. If the hand terminal was connected for the first time to the field device, a warm start is
executed which is completed with the function key
F3 - NEXT. In the display appears the basic menu
for the SIDE Control Type 8635 in the on-line mode.
On first commissioning, execution of the Autotune function is absolutely necessary. SIDE Control
automatically determines the optimum settings for the current operating conditions (see also the
chapter
Operating and Controller Functions).
The menu item AUTOTUNE is to be found in the Main menu under item 2.
AUTOTUNE procedure (required on first commissioning)
Select the menu item AUTOTUNE in the Main menu via the operating keys or and then start the
function via the operating key . The following message appears.
Message after start of
the AUTOTUNE function.

With F3 - ABORT you can quit the AUTOTUNE function without starting.
With F4 - OK you confirm the start.
After pressing the F4 key, a warning message appears that the AUTOTUNE function may cause
malfunctions in the running process.
