Real Time Clock Adjust - 0 255 117
This parameter trims precisely the real
time clock circuit. Values from 0 to 63
speed up the clock with 0.25sec/day
steps. Values from 127 to 64 slow down
the clock with 0.25sec/day steps.
Hysteresis Voltage V-AC 0 30 8
This parameter provides the mains and
genset voltage limits with a hysteresis
feature in order to prevent faulty
decisions.
For example, when the mains are
present, the mains voltage low limit will
be used as the programmed low limit.
When the mains fail, the low limit will be
incremented by this value. It is advised
to set this value to 8 volts.
