8.2 Commissioning instructions
Before you can start with the adjustment work the system-specific connections
have to be made.
The following table just shows an overview of measures to be taken when the
amplifier module is to be commissioned initially. A detailed description can be found
in chapter 8.3, "Fine tuning of the complete system" on page 40.

of the complete
system
When the electronics leaves the factory, it is characterized by the following features:
• Minimum ramp times
• Sensitivity of GW is set to 100 %
• The linearity of the complete system (module electronics and valves) is subject to
series production tolerances
Ready for operation (green)
Enable (yellow)
Measure
Set DIL switch (inside the amplifier module) while the amplifier
is disconnected from the power supply (see chapter 8.1.1,
page 33).
Connect amplifier module
Adjust pressure command value zero point (→Zw)
Set ramp times.
Internal: by means of amplifier module (see "ramp generator
(3)" on page 15 )
External: via machine control
Set maximum value of pressure command value (→Zw)
Measure
Fine tuning of the complete system according to
chapter 6.5.
