Danfoss ERC 102 - 6. CONFIGURATION OF INPUTS AND OUTPUTS; 6.1 Changing input and output configuration settings

19
The ERC 102 inputs and outputs are configurable by
the customer. Before getting started it is a good idea
to check if all inputs are configured correctly and
match the sensors attached.
Input and output configuration settings are part of
the assignment menu (ASi).
NOTE: Coded sensors will impact on the number of
possible configurations.
For instance: Danfoss supplies only 2-pole defrost
sensors, so input S3 will most likely be used as a
defrost / evaporator temperature sensor input.
Please contact your local Danfoss representative for
information about default settings.
6. CONFIGURATION OF INPUTS AND OUTPUTS
6.1 Changing input and output configuration settings
Example: Input S1 is attached to a temperature sensor. The sensor measures cabinet temperature.
Example: Input S2 is attached a digital on/off sensor which is a door open / closed switch.
There are two steps to inputting the configuration:
1. Define the type of sensor attached to the input:
- Temperature / light / digital
2. Define the application for the sensor:
- Temperature: control / condenser / evaporator
- Light: ECO / display / both
- Digital: door sensor
