ALARMS
LCD A 258 Indication Alarm description Effect / Symptom
PPP TIMEOUT
Third pressure pulse from 0.00
to process start not completed
within timeout.
Third pressure rise from 0.00 to specic pressure
value for selected cycle (1.10 bar / 2.15 bar) not
completed within timeout.
Possible causes / Checks Solution
Problem with autoclave
loading – check load.
Check quantity and arrangement of load inside chamber.
Observe the indications provided in the User Manual.
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 steam
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.
Steam seepage through
door gasket.
Clean door gasket and steel ledge thoroughly.
Change door gasket.
Problem with door sealing –
check closing system.
Check for steam leaks through door.
Check condition and position of door gasket.
Check for proper operation of door closing and locking system.
To perform this check, it might be a good idea to activate the closing system from menu
SERVICE/COMPONENT TEST/DOOR – SQ 20, measuring the current demand from
the locking servomotor.
LCD A 260 Indication Alarm description Effect / Symptom
PPD TIMEOUT
Chamber depressurization not
completed within timeout.
Problem with solenoid valves opening changeover
during steam discharge.
Possible causes / Checks Solution
EV3 shaft will not slide.
Clean and/or replace cursor and cursor holder of EV3 – see technical datasheet
ST02 - MANIFOLD.
EV3 dirty.
EV3 not powered on.
Check EV3 wiring.
Check EV3 supply.
To perform this check, activate the EV3 from menu SERVICE - SQ 15.
Check position of autoclave
feet.
If any feet have been removed, ret them.
Instruct operators.
Adjust feet to achieve proper autoclave inclination.
Check chamber lter
Clean chamber lter.
Change chamber lter.
