ALARMS
Possible causes / Checks Solution
Problem with discharge
solenoid valves EV1 – EV3
– check components.
Problem with changeover
solenoid valve EV4-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.
Check for proper power supply to EV4, with direct discharge/vacuum pump connection
changeover.
MANIFOLD - see datasheet ST02.
Problem with heat
exchanger – check device.
Problem with autoclave
position.
Check that exchanger grid and ns are clean.
Conrm activation of cooling fans.
Check free space at rear end to let hot air out.
Check that air suction lter under autoclave is clean.
Check autoclave position on supporting surface, it must ensure that chamber is at
proper angle towards bottom.
LCD A 254 Indication Alarm description Effect / Symptom
PP2 TIMEOUT
Second pressure pulse did not
reach 0.00 bar within timeout.
Second pressure rise from – 0.80 to 0.00 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.
