The following parameters will need to be considered for ESM even if P1210 is dif-
ferent to setting 6 in normal operation mode:
P1212 (time to first restart)
P1213 (restart time increment) = 30 seconds default
If P1210 = any setting other than 6 when ESM is not activated (normal operation mode),
when ESM is active the setting of 6 will not be visible as this will occur internally.

Acknowledging a fault when ESM/Fire Mode is first en-
abled
If a fault is active prior to ESM/Fire Mode being enabled, when ESM is enabled the
SED2 will acknowledge, restart and ignore all 'soft faults' and attempt to acknowl-
edge and restart any 'hard faults'. If a hard fault is still present, then the SED2 will
trip and attempt again indefinitely or until the SED2 is destroyed.

ESM/Fire Mode Control Words for the SED2
