EKD 316 – Parameter identification (modbus)
Explanations:
Parameter – The parameter name and abbreviation
PNU
– The Parameter Number.
Note: This is equivalent to the modbus register number (modbus address + 1)
R/W
– R means read only, RW means it can be changed
Config lock – If the parameter is config locked it means that the value can only be changed when the main switch is off
Min
– The minimum value of the parameter
Max
– The maximum value of the parameter
Default
– The default value of the parameter (factory setting)
Actual value – Values are read/written as 16 bit integer values without decimals. This is the default value as read via modbus
Scale
– This shows the scaling factor of the value. *1 means that there is no scaling. *10 means that the read value is 10 times larger than
the actual value.

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, an incorrect installation, for example, could
still present problems. Electronic controls are no substitute for
normal, good engineering practice.

Danfoss will not be responsible for any goods, or plant
components, damaged as a result of the above defects. It is the
installer's responsibility to check the installation thoroughly, and
to fit the necessary safety devices.
Particular attention is drawn to the need for a "force closing" signal
to controllers in the event of compressor stoppage, and to the
requirement for suction line accumulators.
Your local Danfoss agent will be pleased to assist with further
advice, etc.
