The wire sections are given for information.
Even so, the sections shall be defined by taking contacts with the wire provider.
They depend:
•
of the wire type
•
of the length
•
of the room temperature
•
of the wire path
Alarm report:
The connection of the alarm report on automate unit must be done by the person in charge of the installation.
He must control the compliance wiring and proper operation during the final acceptance test.
8.2 Communication between each concentrator
For multiple-line, PROCOM 2 are to be connected between them by the RS 485 n°1 according to wiring below, putting a resistant of
120 ohms at the two ends:
8.3 Micro cuts / Switch off by the master switch
If a concentrator is stopped during a cycle, when it will start again, its oxygen rate will be degraded.
It is strongly advised to equip the PROCOM 2 supply with an uninterruptible power supply (inverter) to avoid micro
cuts. (consumption of 0.2 A in 1-phase 230V).
Sometimes, during the starting of the compressor, the uninterruptible power supply (inverter) can cause a micro cut.
We strongly advise you to set up the inverter proposed by MIL'S SAS.
If it is necessary to cut the concentrator electrically, we advise you to stop the concentrator by its On/Off button. When the
concentrator is stopped, switch off by the master switch.
