Compressor Action (Cp1-Cp); Safety Compressors (Cp9-Cp) - Emerson XC1008D Installing And Operating Instructions

6.1.8 Compressor Action (CP1-CP8)
CP1 Regulation band width for compressors- circuit
1÷50°F; 10÷1000 KPA) The band is symmetrical compared to the target set point, with extremes:
SETC1+(CP1)/2 ... SETC1-(CP1)/2. The measurement unit depends on the C45 par.
NOTE: If the circuit 1 has 1 relay set as a frequency compressor (Frq1), the 1Q19 parameter is
used instead of the CP1 parameter: regulation band width that is added to the set point 1.
CP2 Minimum compressor set point - circuit 1 (AI2 ÷ SETC1 bar, PSI or KPA; -50.0 ÷ SETC1 °C; -58.0
÷ SETC1 °F). The measurement unit depends on C45 parameter. It sets the minimum value that can
be used for the compressor set point, to prevent the end user from setting incorrect values.
CP3 Maximum compressor set point - circuit 1 (SETC1÷AI3 bar/PSI/KPA; SETC1÷150.0°C;
SETC1÷302°F)
The measurement unit depends on C45 parameter. It sets the maximum acceptable value for
compressor set point.
CP4 Compressor energy saving value - circuit 1 (-20.00÷20.00bar; -50.0÷50.0 °C; -300÷300 PSI; -
90÷90 °F; -2000÷2000KPA) this value is add to the compressor set point when the energy saving is
enabled.
CP5 Regulation band width for compressors - circuit
1÷50°F; 10÷1000 KPA). The band is symmetrical compared to the target set point, with extremes:
SETC2+(CP5)/2 ... SETC2-(CP1)2. The measurement unit depends on the C43 par.
NOTE: If the circuit 1 has 1 relay set as a frequency compressor (Frq2), the 2Q18 parameter is
used instead of the CP5 parameter: regulation band width that is added to the set point 2.
CP6 Minimum compressor set point - circuit 2 (AI5 ÷ SETC2 bar or PSI o KPA; -50.0 ÷ SETC2 °C; -
58.0 ÷ SETC2 °F).
value that can be used for the compressor set point, to prevent the end user from setting incorrect
values.
CP7 Maximum compressor set point - circuit 2 (SETC2÷AI6 bar/PSI/KPA; SETC2÷150.0°C;
SETC2÷302°F)
The measurement unit depends on C45 parameter. It sets the maximum acceptable value for
compressor set point.
CP8 Compressor energy saving value - circuit 2 (-20.00÷20.00bar; -50.0÷50.0 °C; -300÷300 PSI; -
90÷90 °F) this value is add to the compressor set point when the energy saving is enabled.
6.1.9 Safety Compressors (CP9-CP19)
CP9 Minimum time between 2 following switching ON of the same compressor (0÷255 min).
CP10 Minimum time between the switching off of a compressor and the following switching on.
(0÷255min).
Note: usually CP9 is greater than CP10
CP11 Time delay between the insertion of two different compressors (0 ÷ 99.5 min; res. 1sec)
CP12 Time delay between switching off of two different compressors (0 ÷ 99.5 min; res. 1sec)
CP13 Minimum time load on (0 ÷ 99.5 min; res. 1sec)
CP14 Maximum time load on (0 ÷ 24 h; with 0 this function is disabled.) If a compressor keeps staying on
for the CP14 time, it's switched off and it can restart after the CP10 standard time or after the CP15
time with frequency compressor (Frq1 or Frq2).
CP15 Minimum time a frequency compressor (CP1..CP15 =Frq1 or Frq2) stays off after CP14 time
(0÷255 min)
CP16 CP11 delay enabled also for the first call. If enabled, the triggering of the step is delayed for a
"CP11" time, respect to the call.
no = "CP11" not enabled;
yES="CP11" enabled
CP17 CP12 delay enabled also for the first off. If enabled, the triggering of the step is delayed for a
"CP12" time, respect to the call.
no = "CP12" not enabled;
yES="CP12" enabled
CP18 Output delay at power on (0 ÷ 255 sec)
CP19 Booster function enabled:
no = compressors of 2 circuits work independently
yES = if at least one compressor of the circuit 1 (BT) is ON, also one compressor of the circuit 2
(TN) is enabled, independently from the pressure of the circuit 2. This ensures that the gas coming
from the circuit 1 is suct by the compressors of the circuit 2.
