Alta press. bypass ALA06 Bypass water pressure
> 4 bar
Possible return of pressurised water through the bypass.
Verify:
• that the bypass discharge solenoid valve is capable of
discharging water;
• correct operation of the mechanical overfl ow valve
(opens at 4 bar).
If necessary, replace the BYP bypass discharge solenoid
valve and/or the overfl ow valve.
Manual Active Signal
Alta temp. bypass ALA08 WRA12 warning
triggered more than 3
times in 1 hour
Prolonged recirculation of water through the bypass is
possible. Verify:
• that the humidifi cation capacity set on the Dc18
screen is equal to no. of nozzles x capacity of the
single nozzle;
• that the zone is capable of delivering a water fl ow rate
≥ the minimum fl ow rate supplied by the pump;
• that the NTC probe is connected to terminals J5.2-J5.3
Manual Active Signal
c.pCOe offl ine ALA11 c.pCOe disconnected
from c.phc or wired
incorrectly
The c.pCOe expansion that regulates zone 2 is offl ine.
Verify:
• the exactness of the machine model (the alarm is
triggered if the cabinet is single zone but the c.phc
control is confi gured for dual zone);
• that the wiring between c.phc (terminal M3) and
c.pCOe (terminal J6 BMS) respects the pola, -,
GND as shown in the wiring diagram;
• that c.pCOe is powered (24Vac between G-G0 on
terminal J1).
