AK-LM 350
Operating AKM / Service tool
The setup of the controller itself can only be carried out via AK-ST
500 service tool software. The operation is described in fitters on
site guide.
If the controller is included in a network with an AKA gateway one
can subsequently carry out the daily operation of the controller
via AKM system software, i.e. one can see and change daily read-
outs/settings.
Note: AKM system software does not provide access to
configuration settings of the controller.
Measurements from all of the signals received and from the most
important displays of the individual functions can be seen.
All COP measurements are displayed.
All alarms can be received by AKM.

Installation considerations
Accidental damage, poor installation, or site conditions, can give
rise to malfunctions of the control system, and ultimately lead to
a plant breakdown.
Every possible safeguard is incorporated into our products to
prevent this. However, a wrong installation, for example, could
still present problems. Electronic controls are no substitute for
normal, good engineering practice.
Danfoss wil not be responsible for any goods, or plant compo-
nents, damaged as a result of the above defects. It is the install-
er's responsibility to check the installation thoroughly, and to fit
the necessary safety devices.
Special reference is made to the necessity of signals to the
controller when the compressor is stopped and to the need of
liquid receivers before the compressors.
Your local Danfoss agent will be pleased to assist with further
advice, etc.
