Parameters Programming - Emerson Dixell XC645D Installing And Operating Instructions

•
LInJ: status of the injection output ("On" – "OFF"), This information is available
only if one relay, oA2 ÷oA4 is set as "Lin".
•
SEtd: value of the Dynamic Set point.
This information is available only if the Dynamic set point function is enabled (par.
dSEP ≠ nP)
•
dStO: percentage of the PWM output driving the valve of the Digital Scroll
compressor.
•
dSFr: value of temperature or pressure when the regulation filter of Digital Scroll
compressor is enabled (par. dFE=YES). The "regulation filter" function calculates
the average value of the pressure/temperature during a PWM cycle, and uses this
value for the control algorithm
•
AO1 Percentage of the analog output 1 (4-20mA or 0-10V).
•
This information is always available
•
AO2: Percentage of the analog output 2 (4-20mA or 0-10V).
•
This information is always available
•
SSC1: Supervising Set for circuit 1, if supervising system is sending the set point
to the controller
•
SSC2: Supervising Set for circuit 2, if supervising system is sending the set point
to the controller
•
SStF: Supervising Set for fan, if supervising system is sending the set point to the
controller
•
SH: Superheat
EXIT: push the SET+UP keys together.

11. Parameters programming

11.1 How to enter the "Pr1" parameter list
To enter the "Pr1" parameter list, user accessible, operate as follows:
1. Hold pressed the SET and DOWN key for 3s.
2. The controller displays the name of the parameter in the Lower display, its value on the Upper
display.
3. Press the "SET" key: the value of the parameter will start blinking.
4. Use "UP" or "DOWN" to change the value.
5. Press "SET" to store the new value and move to the following parameter.
To exit: Press SET + UP or wait 30s without pressing a key.
NOTE: the set value is stored even when the procedure is exited by waiting the time-out to expire.
11.2 How to enter in parameters list "Pr2"
The "Pr2" parameter list is protected by a security code (Password).
To access parameters in "Pr2":
1. Enter the "Pr1" level.
2. Select "Pr2" parameter and press the "SET" key.
3. The flashing value "0 ---" is displayed.
4. Use o or n to input the security code and confirm the figure by pressing "SET" key.
5. Repeat operations 2 and 3 for the other digits.
