Setting thresholds for speed limit relay output
Setting the lower and/or upper switching thresholds:
The speed limit relay output provides a status signal to external equip-
ment, to indicate that the actual speed has exceeded or fallen below a
set threshold. This signal may be e.g. for speed-dependent rudder angle
limiting or similar applications.
The switching behaviour of the limit relay is determined by the com-
bined settings of two values, the minimum (lower threshold) and the
maximum (upper threshold) value:
If only a minimum threshold value
is set and active, the relay is
attracted at speeds below and
released at speeds above the
threshold value.
If only a maximum threshold value
is set and active, the relay is
attracted at speeds above and
released at speeds below the
threshold value.
If both a minimum and a maximum
threshold value are set and active,
the relay is released at speeds
below the min. value, attracted at
speeds in-between both values and
released again at speeds above the
max. threshold.
If the max. threshold is set to a
value below the min. threshold, the
relay is attracted at speeds below
the min. value, released at speeds
in-between both values and
attracted again at speeds above the
max. threshold.
If both threshold values are de-activated or set to exactly the same
value, the limit relay function is disabled.
