UECH 210/211 CONTROLALARMERUECH 210/211 utfører et komplett diagnosesystem, og signallerer en serie av alarmer. Alarmenenullstilles manuellt ved å trykke og slippe ON/OFF knappen.Ved aktivering av en alarm, skjer tre ting:• Evt. Brukere blokkeres;• Varsel på tastaurdisplayet• Signallering via en transistorstyrt utgang (12-24V~ med maks. 500mA strøm)Signallering er en “Enn” type kode (nn indikerer et 2 sifret tall som indikerer alarmtypen).Merk: ved feil, sjekk bruksanvisningen, og vedlagte koblingsskjema.Følgende tabell, lister opp mulige alarmer og koder:Alarm code Signalling Description resetE00Remote OffIs activated by the ID4 on/off remoteinputAutomatic on closure of contact(refer wiring diagram)E01High pressureIs activated by the ID1 input of thehigh pressure pressure switchManualE02E05E06Low pressureAntifreezeAI2 sensor failureIs activated by the ID2 input of thelow pressure pressure switchIs activated if the sensor AI2 valuedrops to below 2°cIs activated if sensor AI2 has shortcircuitedor cut off, or the sensoroperating limits have been exceededResetting is automatic until thesystem starts triggering morethan 3 times an hour, in whichcase it becomes manual.Resetting is automatic until thesystem starts triggering morethan 3 times an hour, in whichcase it becomes manual.Automatic after having solvedthe problemE07AI3 sensor failureIs activated if sensor AI3 has shortcircuitedor cut off, or the sensoroperating limits have been exceededAutomatic after having solvedthe problemE40AI1 sensor failureIs activated if sensor AI1 has shortcircuitedor cut off, or the sensoroperating limits have been exceededAutomatic after having solvedthe problemE41E42E43Flow switchAI4 sensor failureAntifreeze alarm (water-water unitwith gas inversion)Is activated by input ID3 of the waterflow switchIs activated if sensor AI4 has shortcircuitedor cut off, or the sensoroperating limits have been exceededIs activated if the sensor AI3 valuedrops to below 2°cResetting is automatic until thesystem starts triggering morethan 3 times an hour, in whichcase it becomes manual.Automatic after having solvedthe problemResetting is automatic until thesystem starts triggering morethan 3 times an hour, in whichcase it becomes manual.E46High temperatureIs activated if the sensor AI1 value isover 18°c for 1200 secondsAutomaticVersjon 1.5NO – Mai 2007 13
