Output Circuit 8 (Call for Remote Flash)
CKT 8 is the “Call for Flash” or “Remote Flash”
function. Its effect on controller operation is
determined by the mode it is programmed for (under
coordination manual/remote programming). When in
the clock mode, the controller will respond exactly as if
the External Flash input had been activated. The unit
will cycle to the Rash entry phase, clear to all red, then
the CVM (Controller Voltage Monitor) output will go
high (+ 24VDC). The monitor will then place the
intersection in flash.
At this point, Flash out (see flash out description, pg 2-
27) will go true (see Note 2), and the unit will enter
flashing operation and remain there until the flash
output is turned off (manually or by event
programming). The unit will at this time return to
normal operation in the interval specified by the Flash
exit interval stored in EEPROM.
Notes:
1.The controller will internally respond to the Flash
call circuit even without the system being called for—
as long as the flash function Is programmed for clock
(under coordination modes menu) or is programmed
auto and interconnect inhibit is active.
2.The time clock “Flash Call” circuit output (CKT 8)
is not the same as the “Flash Output”. The time clock
flash command simply calls for flashing operation and
initiates the sequence. The Flash Output becomes
active when the controller actually reaches the flash
entry point, regardless of the mode of selection, time
clock, FSK, or input. This circuit could be used for any
special requirements applied when the controller
reaches the flash interval (All Red after entry phase).
Also note that Flash out is also pre-empt 6 out—do
not use pre-empt 6 out if remote flash is used.
3. Remote flash can be overridden by pre-empt
sequences- if programmed to do so. Also, preemption
can programmed to provide “Soft Flash”, in which the
load switch outputs provide flashing operation without
dropping the flash transfer relays.
Output Circuits 9, 10, 11, 12
These outputs are general use outputs to be used as
desired in accordance with time clock event
programming, and/or manual programming. These
outputs have no associated internal response.
MAPPABLE INPUTS AND OUTPUTS
A number of inputs and outputs have been added to the
LMD since the inception of mappable I/O. Each time
specific functions have been added, corresponding input
and output functions have been added as well. It is then
up to the user to decide what pin to use these on by
substituting them for seldom used normal functions.
Some examples of such I/O are
Function Parent Function I or O
Pre-empt No delay Pre-emption I
Transit priority inputs Transit Priority I
AW outputs Advanced warning O
PE acknowledge Pre-emption O
