B CLASSIC / B FUTURA / S CLASSIC - TECHNICAL MANUAL
ALARMS
Possible causes / Checks Solution
Problem with generator
warm-up – check device.
Check and reset safety thermostat if needed.
Check steam generator heating element.
See ST01 – steam generator datasheet.
Problem with manifold
solenoid valve sealing –
check components.
Check EV1 for proper power supply and sealing
Check EV3 for proper sealing.
MANIFOLD - see datasheet ST02.
LCD A 252 Indication Alarm description Effect / Symptom
PP1 TIMEOUT
First pressure pulse did not reach
1.00 bar within timeout.
First pressure pulse from 0.00 to 1.00 bar not
completed within timeout time.
Possible causes / Checks Solution
Problem with water
injection pump of steam
generator – check device.
Problem with steam
generator clogging – check
device.
Check feed tank lter and water injection pump inlet lter.
Check for proper activation of water pump and check that EV6 opens.
To perform this check, it might be a good idea to activate vacuum pump and EV6 from
menu SERVICE/COMPONENT TEST/OTHER COMPONENTS – SQ 17, that lets you
detect water owing through the generator and into the chamber.
Identify leaks on tubes connecting water pump and generator.
Change vibration pump.
Steam generator maintenance – see datasheet ST01.
Problem with generator
warm-up – check device.
Check and reset safety thermostat if needed.
Check steam generator heating element.
See ST01 – steam generator datasheet. -
Problem with manifold
solenoid valve sealing –
check components.
Check EV1 for proper power supply and sealing
Check EV3 for proper sealing.
MANIFOLD - see datasheet ST02.
LCD A 353 Indication Alarm description Effect / Symptom
DISCHARGE TIMEOUT
First pressure drop from 1.00 to
0.10 bar not completed within
timeout.
First pressure discharge from 1.00 to 0.10 bar not
completed within timeout time.
Possible causes / Checks Solution
Problem with chamber
drain lter – check
component.
Check and clean chamber lter.
Observe the indications provided in the User Manual.
Problem with discharge
solenoid valves EV1 – EV3
– check components.
Check that EV1 opens properly, not powered on.
Check that EV3 receives proper power supply and opens properly.
Check solenoid valve seat and cursor of EV1 and EV3.
MANIFOLD - see datasheet ST02.
LCD A 253 Indication Alarm description Effect / Symptom
PV2 TIMEOUT
Second vacuum pulse from 0.00
to – 0.80 bar not achieved within
timeout.
Second pre-vacuum not completed within timeout
time.
Possible causes / Checks Solution
Problem with vacuum
pump activation – check
component.
Conrm vacuum pump start-up.
To perform this check, it might be a good idea to activate the vacuum pump from menu
SERVICE/COMPONENT TEST/OTHER COMPONENTS – SOLENOID VALVES SQ
14, that lets you detect air suction from the chamber.
Measure pump power supply voltage.
Change vacuum pump.
