Explanation for alarm output
name Explanation
Over current 45 A (r.m.s) over current
Over temperature
head sink
Heat sink temperature is above 85’C
Power error Circuit power is connected but load power is not connected
Heat break Load is disconnected
SCR short Without control output, current flows continuously
