** PURGE will be determined by which ST7800A purge card is selected; 15 timings are available from 2 seconds to 30 minutes.
NOTE: Allowable inrush can be up to ten times the pilot duty
rating.
EXAMPLE: Pilot duty rating = 50 VA.
At 120 V, running current is:
50/120 = 0.42A.
Maximum allowable inrush is ten times 0.42A = 4.2A.
