CONFIGURATION CODE
The KX1 can be easily configured by the “Code Configuration” method for the most common requirements, just entering two 4-digit
codes: Cod1 [LMNO] for the Input Type and Control Mode selection and Cod2 [PQRS] for the Alarms and the Service Functions.
For complete controller configuration see the Engineering Manual.
Note: Before starting the configuration code setting, please define and write down Cod1 and Cod2 as needed:

Note: 1.Wattmeter Instantaneous power is continuously computed
as multiplication of the Load Voltage, Load Current parameter
values and the controller output instantaneous value.
2.Wattmeter power consumption is the estimated hourly
energy consumption (using Load Voltage and Load Current
parameter values), computed on the previous 15 minutes
period. The readout is updated every 15 minutes.
3.Worked Time counter is continuously increased when
the controller is turned ON.
