CONTROLLING ZONE LEDS (CONTINUED)
For example, an equation of R65=Z1:20(1)A
will result in alarm LED 1 turning on steady whenever one or more zones in the range 1 to
20 has an
unisolated
alarm.
An equation of R256=PLI , will result in isolate LED 64 turning on steady when PLANT is
isolated.
An equation of R129=SFT , will result in fault LED 1 turning on steady whenever there is a
system fault.
RDU Zones 129-192
If any output logic equations are used to control zone LEDs, then the status transmitted to an
RZDU will include data for "zones" 129 to 192 (otherwise zones 129 to 192 are not sent to
an RZDU). The status of zones 129 to 192 as sent to an RZDU is generated from the output
logic equations which control the LEDs, where zones 129-192 correspond to LEDs 1 to 64.
For example, with equations
R65=Z1:20(1)A, R129=Z1:20(1)F and R193=Z1:20(1)I
then the status of zone 129 at an RZDU would show alarm if any of zones 1 to 20 at the
F3200 controller had an unisolated alarm, and similarly for fault and isolate.
NOTE
At the F3200 controller, zones 129 to 192 actually correspond to open collector
outputs and are NOT the same as zones 129 to 192 at an RZDU.
7.4.9 PROGRAMMING ZONE ISOLATE/DE-ISOLATE/RESET COMMANDS
F3200 allows the programming of equations which initiate zone isolate, zone deisolate or
zone reset commands. These commands have the same effect as if the operator initiated
the command using the keypad. With V2.08 or earlier software, these commands can be
used with alarm zones only (zones 1 to 64). With V2.09 or later, these commands can be
used with module relays (using zone numbers 65 to 128), ancillary relays (zones 193 to 196)
and plant (zone 197).
7.4.9.1 ENTERING OUTPUT LOGIC ZONE COMMANDS
Selecting one of the menu options from output logic menu two "4:Zone isol 5:Zone deisol
6:Zone reset" will show the first programmed equation of that type. Pressing NEXT and
PREV steps forward and back through the list of equations of that type. The equation is
shown with a "first zone" and "last zone" and the command is applied to the range of zones
specified inclusively. If the first zone is the same as the last zone then the command applies
to that zone only. If there are no equations of the selected type then a "blank" equation is
shown with the first zone and last zone equal to zero. A "blank" equation is also shown after
stepping through all existing equations of the selected type and this can be used to enter a
new equation.
