CONTROL OF TWO COMPRESSORS FOR A PRO2XY CONCENTRATOR
12.1 Schematic diagram
12.2 Operation
When the concentrator starts, it gives the order at least to one compressor to start. There are a priority compressor and an auxiliary
compressor. The inversion of the priorities is made when the request of concentrator operation will have carried out a 2 hours
cumulated time (adjustable).
If the air pressure reaches the auxiliary threshold, then a compressor starts.
If the air pressure reaches the back-up threshold, then the 2 compressors start.
If a compressor is defective, it is indicated on the display of the MILLENIUM and the second compressor starts. When the 2 compressors are
defective, then an alarm is sent to the PROCOM2 of the concentrator in order to block the concentrator operation.
12.3 MILLENIUM description
Line n°1: display of the air pressure at the concentrator inlet (bar).
Line n°2: Compressor A status "running" or "fault". Without indication, the compressor A is off.
Line n°3: Compressor B status "running" or "fault". Without indication, the compressor B is off.
Line n°4: Parameters access.
12.3.1 Parameters (line n°4)
To consult parameters, press the "A" key.
STOP COMP. 0009.0 b:
Stop threshold of compressors at 9 bar. This threshold is adjustable.
HYST.APP. 0002.5 b
: Hysteresis of auxiliary compressor interlocking with the following pressure:
STOP COMP.
–
HYST.APP. = 9
–
2.5 = 6.5 bar. This value is adjustable.
HYST.SEC. 0001.0 b: Hysteresis of interlocking of the two back-up compressors with the following pressure:
STOP COMP.
–
HYST.APP.
–
HYST.SEC. = 9
–
2.5 -1 = 5.5 bar. This value is adjustable.
HM A: 00012 h: Hour meter compressor A
HM B: 00011 h:
Hour meter compressor B
FLEXO T. 00090 s:
Time delay of stop compressor (in seconds) when the pressure reaches the threshold
« STOP COMP. ». Temporization is reset as soon as the threshold of compressor interlocking is reached.
This temporization is adjustable.
PRIO.T.COMP 00002 h: Time of priority inversion of the two compressors, in hour. This time is adjustable.
