Low Limit:
Low limit value for the V(L-N) alarm. (For Virtual Keyboard Refer to 3.1.4 E.g.) . In order to
set an alarm for V(L-N), operator should enter a low limit value smaller than the high limit
value. When low limit and high limit values are entered to be the same, V(L-N) alarm will
be deactivated (no alarm will be set).
High Limit:
High limit value for the V(L-N) alarm. (For Virtual Keyboard Refer to 3.1.4 E.g.) . ). In order to
set an alarm for V(L-N), operator should enter a high limit value larger than the low limit
value. When low limit and high limit values are entered to be the same, V(L-N) alarm will
be deactivated (no alarm will be set).
Delay:
When the related alarm parameter exceeds the “Low limit” or “High Limit” value; before
declaring an alarm, Klea waits for “delay time”. Similarly, when the related alarm parameter
enters into the limit values, Klea waits for “delay time”, before cancelling the alarm. “Delay”
can be adjusted between 0 600 sec. (For Virtual Keyboard
Refer to 3.1.4 E.g.) .
Delay 0 sec

Hysteresis:
It is the tolerance entered as percentage for high and low limits . Hysteresis can be adjusted
between 0 20 (For Virtual Keyboard
Refer to 3.1.4 E.g. ). Examine following example and
Fig. 3-52 )
Hysteresis 0.0 %

E.g.
For the following figure(‘Delay’ is adjusted to be zero);
At point A, alarm occurs
At point B, alarm disappears
At point C, alarm occurs
At point D, alarm disappears
