Figure 4-102 Reset Delay Timer Logic Diagram
Change Active Profile (ISSLogic ® )
To change the active profile simply select the desired
profile. The “Not activated” selection means the
profile will not be changed. If the presently active
profile is selected as the profile to which to change
there is effectively no change since it would change
to the same profile.
When an ISSLogic Function is enabled and the
logic becomes “true” the ISS# is always activated
so it could be used as an initiating input to any other
ISSLogic.
Since there are six ISSLogic Functions per setting
profile, depending on the number of different MBTS
settings defined, the scheme may provide up to 24
different logic schemes.
DO/RST (Dropout/Reset) Timer Feature
The DO/RST timer can be set as either Dropout or
Reset mode. The operation of the Dropout Delay
Timer and the Reset Delay Timer are described
below.
Dropout Delay Timer
The Dropout Delay Timer logic is presented in
Figure 4-101. The Dropout Delay Timer feature
allows the user to affect an output time delay that
starts when the ISSLogic PU Status drops out (A)
and can hold the Output (D) status true beyond the
Output Seal In Delay value (C).
However, the Seal In Delay (E) may hold the Output
(B) true if the time after ISSLogic PU Status dropout
(A) and Dropout Delay Timer value (D) are less than
the Seal In Delay time (E).
Reset Delay Timer
The Reset Delay Timer logic is presented in Figure
4-102. The Reset Delay Timer feature allows the
user to delay the reset of the PU Time Delay Timer
and hold the accumulated timer value (A) for the
duration of the Reset Time Delay time period (B).
The Reset Delay Timer starts when the ISSLogic
PU Status drops out (C).
If the ISSLogic PU Status remains dropped out (D)
after the reset delay has timed out, then the ISSLogic
PU timer value will be reset to zero (E).
If the ISSLogic PU Status reasserts (F) while the
Reset Delay Timer is still timing, then the PU Timer
Delay begins timing from the accumulated value (G).
