Overview of the Eiger Control System
The S3 Intellisys controller is used to control the operations of the air compressor. The following
troubleshooting guide will allow you to troubleshoot the compressor components. The controller will come in
two standard configurations, one is
STD
(standard) the other is
ENH
(enhanced). The difference is the options
that are enabled in the software of the controller when the compressor is ordered. If the compressor is ordered
with a standard controller the compressor can be upgraded to an enhanced unit with an upgrade kit CCN
23083637. The upgrade kit includes instruction for retrofitting a standard controller to an enhanced controller.
The controller has 3 analog inputs, 8 digital inputs, 6 relay outputs, 1 analog output and two serial 485
communication ports. The controller has a 24VAC input while the internal power supply is a 24 VDC unit that
must sustain a 40 ms power loss before resetting. The S3 controls all aspects of machine operation including
starting, stopping, loading and unloading, safety shutdowns, and user interface as well as compressor remote
connectivity to other devices
.
This controller is different than other Intellisys controllers in that the relay outputs are not solid state triacs,
they are relays that are turned on an off by an internal 24 VDC power supply controlled by the internal
software. There will be no voltage leakage as you find with triacs. So fault finding will be easer due to fact that
if a relay output is on or off due to a problem with the controller simply replace the controller, there are no user
serviceable parts. The analog output (X06 term 1-2) for the PORO horn ( 4-20 Ma output ) simply energizes
the solid state relay when the unit starts after a power outage.
A user interface shows the status of the compressor while it is running. The display uses ISO symbols to
convey information to the operator and it will be necessary to learn the symbols as well as the menu structure to
troubleshoot the compressor. Pass codes are required to enter the Set up Access screen, and Fault History
(0000), and Advanced Set Up (0101). These codes are provided in this manual and the operator’s manuals. This
troubleshooting guide also includes the pass code for the Factory Setup that is to only be used by IR service
technicians and not given to customers (Code is 1954). The next pages give an overview of the buttons on the
controller as well as the ISO symbols and software navigation.
