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
