USE OF THE PROGRAMMING “HOT KEY “
16.1 How to program a hot key from the instrument (UPLOAD)
1. Program one controller with the front keypad.
2. When the controller is ON, insert the “
Hot key
” and push o key; the
"uPL"
message appears
followed a by flashing
“End”
3. Push “
SET”
key and the
End
will stop flashing.
4. Turn OFF the instrument remove the
“Hot Key”,
then turn it ON again.
NOTE:
The “
Err
” message is displayed for failed programming. In this case push again o key if
you want to restart the upload again or remove the “
Hot key
” to abort the operation.
16.2 How to program an instrument using a hot key
(DOWNLOAD)
1. Turn OFF the instrument.
2. Insert a
programmed “Hot Key” into the 5 PIN receptacle
and then turn the Controller ON.
3. Automatically the parameter list of the
“Hot Key”
is downloaded into the Controller memory,
the “
doL
” message is blinking followed a by flashing
“End”.
4. After 10 seconds the instrument will restart working with the new parameters.
5. Remove the
“Hot Key”.
NOTE: T
he message “
Err
” is displayed for failed programming. In this case turn the unit off and
then on if you want to restart the download again or remove the “
Hot key
” to abort the
operation.
The unit can UPLOAD or DOWNLOAD the parameter list from its own E2 internal memory
to the
“Hot Key”
and vice-versa.
LIST OF PARAMETERS
17.1 Plant dimensioning and type of regulation.
The EC2-XC645CX is pre-set to drive a Digital Scroll compressor.
The relay 15-17 is set to manage the Digital compressor, while the TRIAC output 17-19 drives its
solenoid valve.
oA1 (term. 15-17), oA2 (term. 16-17), oA3 (term. 17-18), oA4 (term. 17-20), oA6 (term. 21-22)
outputs 2 3 4 6 configuration
: by means of these parameters the plant can be dimensioned
according to the number and type of compressors and/or fans and the number of steps for each
one.
Each relay according to the configuration of the oA(i), where (i) = 1, 2, 3, 4, 5, 6 parameters can
work as:
-
Not used: oA(i)
= nu
-
Compressor circuit1
:
oA(i)
= cPr1,
-
Digital compressor
:
oA1
= dGS
-
Blocked bank for Digital Stream
®
6D
:
oA(i)
= 6dG
-
Step:
oAi = StP
-
Fan:
oAi = FAn
-
Fan with inverter/ECI fan:
oA(i)
=
InF
-
Injection of cooling liquid:
oAi =
Lin
-
Alarm:
oAi = ALr
-
Flood protection function: oA(i)
= Liq
-
Valve for hot gas injection in case of low superheat
:
oA(i)
= HGi
