Emerson Dixell iProChill IPC115D Application Manual page 131

Pd 8 Maximum number of pump down alarm interventions per hour, at started-up.
Exceeding this limit, the alarm must be reset manually, it will be saved in
the log and the alarm relay + buzzer will be activated
Reset is always manual if Pd8 = 0
Reset is always automatic if Pd8 =60
Reset switches from automatic to manual if Pd8 falls between 1 and 59
and based on the configuration of Par. Pd9
Pd 9 Pump down alarm automatic or manual reset activation upon start-up
0= the alarm remains in automatic reset even if the number of
interventions per hour is met
1=enables manual reset when the number of interventions per hour is
met

Parameter Description
FA1 Fan regulation
0= absent
1= always ON
2 =ON/OFF step insertion
3= continuous ON/OFF step insertion
4= speed proportional regulator
FA2 Fan working mode
0= depending on the compressor
1= independent from the compressor
FA3 MAX speed fan peak time after ON (TRIAC) At every start-up the fan is
powered at maximum voltage for time FA03, irrespective of the
condensation temperature/pressure. When this elapses, the fan
continues at the speed set by the regulator.
FA4 Fan phase displacement analog output 5 (only if configured as PWM /
phase cut)
FA5 Fan phase displacement analog output 6 (only if configured as PWM /
phase cut)
