Recorded data
16
When the fault indicator provides an alarm
signal, the current values at the moment of the
alarm, the duration of the start of the different
units and other parameters are stored in a
five-place memory stack. A new event moves the
old values up one place and adds the new value
to the first place of the stack which contains
registers 1...8. Five events are memorized - if a
sixth alarm occurs, the oldest set of values will be
lost. A master reset (pressing the push-buttons
