2 Control System Use and Connection
2.1 Standard function
Figure 1: FSCurtis ICommand-Touch. The actual design of the membrane keyboard may vary from the
one
shown in this figure.
The ICommand-Touch is an intelligent compressor control system which can be
extended.
It can be used for oil-lubricated screw compressors with a fixed speed and for converter
machines. Lento (oil-free) compressors can also be controlled with an extra module which
extends the input / output level.
The ICT also has a basic load cycle function to ensure equal utilization in up to five
compressors at the same time (ICT as basic load cycle master with up to 4 basic load
cycle slaves).
All settings can be made via the graphic interface in the code-protected menu system.
The base screen display provides a quick overview of the system type and status at all
times.
Extra information such as progression charts and compilations of all pressure and
temperature values can be quickly accessed by simply tapping on them.
Replacement battery p/n: F1481503

3846 Menu Service The menu system is displayed in full. You can
change any of the parameters.
Caution As of the factory level, this code cannot
be changed in the Configuration menu!
3.3.1 Accessing the menu system
Once a menu code has been entered, the display switches to the main menu. Depending
on code level, access is linked with various authorizations. Parameters are either just
displayed or can also be modified. The more critical a setting is to the safety of the
system, the higher the associated code level (see also Table 1).
After commissioning and/or once ten operating hours are reached, the fixed service code
is deactivated and replaced by a dynamically issued 24h code. The control system
generates a random number and displays it. If this number is sent to Service/ FSCurtis, a
day code, applicable for 24h, is provided.
There is a separate code for specifically deactivating the fixed factory code, regardless of
the operating hours counter.
3.3.2 Additional screenshot generation function
The ICommand-Touch allows you to generate screenshots during operation, and save
them on SD card. To do this, first enter the appropriate code (see Table 1), insert an SD
card that is not write-protected, and ensure it is ready.
To produce a screenshot, click on the title bar in the relevant display.
3.3.3 Commissioning functions
To commission converter machines in the best possible way, you can run a run-in routine.
To do this, first enter the appropriate code (see Table 1). Normal operation is not possible
until the run-in phase is complete.
