A position as shipped, to the reset input of all other
frequency-select
function-tone
decoders
through
U5B-4,15, JP2A, and J6-6 or P6-6.
When simultaneous set and reset inputs are applied
to the F1 latch, set dominates at the Q output and the
high
at
U4A-3
energizes
the
F1
relay
through
U5G-7,12. Simultaneously, the reset low applied to the
F2 latch and all other connected latches resets the pre-
viously set latch. On the trailing edge of the F1 detect
pulse, the reset pulse to the F1 latch and all other con-
nected latches terminates, but the low to the set input
of the F1 latch remains a few microseconds longer due
to the time constant of R28 and C14. This insures that
latch F1 will remain in the set condition.
If the JP2 jumper plug is in a no-bridge condition
(hang on one side), F1 will reset F2 and vice versa, but
other function-tone boards are unaffected. This allows
operation with more than one 1-of-N group in multi-
ple-function-tone-board operation.
If JP2 is in the B position, a continuous reset low is
applied to both the F1 and F2 latches. Upon termination
of the F1 or F2 function-tone decode pulse, the latch is
therefore reset. This momentarily energizes the relay for
about 30 ms.
Warranty (Limited)
All Vega signaling products are guaranteed against
malfunction due to defects in materials and workman-
ship for three years, beginning at the date of original
purchase. If such a malfunction occurs, the product will
be repaired or replaced (at our option) without charge
during the three-year period, if delivered to the Vega
factory. Warranty does not extend to damage due to im-
proper repairs, finish or appearance items, or malfunc-
tion due to abuse or operation under other than the
specified conditions, nor does it extend to incidental or
consequential damages. Some states do not allow the
exclusion or limitation of incidental or consequential
damages, so the above limitation may not apply to you.
This warranty gives the customer specific legal rights,
and there may be other rights which vary from state to
state.
