Page: 16 / 92

Normally Closed (NC) and Normally Open (NO) contact position.
•
On Batt
: This relay energizes when Utility Input line power is unqualified.
•
IMPORTANT:
When the AC input and output circuit breaker is turned OFF, an auxiliary
switch of the circuit breaker opens which disables the On Batt. contact at the Green
Control Terminal Block. This prevents the intersection lights from flashing.
•
Low Battery:
These relays energize when the battery drops below the programmed
battery capacity. The default value is 47.5VDC or 40% battery capacity.
You can change the preprogrammed value to match the batteries used and the
actual operating conditions. See Section 9.7 Battery Maintenance.
•
Timer:
These relays energize after the unit has been in Battery mode for the
programmed time period. The factory default value is 2 hours. The time can be
programmed to be from 15 min. to 8 hours in 15 minute increments.
•
Program Input
: The programmable input contact can be programmed for one function
such as: Self-test, EXT Alarm, EXT Battery Alarm, EXT Fan Failure, Door Interlock.
Jumper the TB 19 & 20 on the Green Control Terminal Block and the program alarm
will show on LCD display.
•
PTS:
TRTC-2002-N1 sends a 48VDC signal from the batteries to the PTS, which
activates the PTS, resulting in transfer from Input power to BBS power. See Section
1.3, Wiring, of this manual for connection instructions.
These contacts have a maximum rating of 1 Amp at 120V. Only the first On Batt contact
is illustrated. The remaining 5 contacts for Low Battery, Timer, etc. are similar.
1) 6 sets of programmable contacts have the following factory default settings:
C1, C2 = “On Batt”
C3, C4 = “Low Batt @ 47.5VDC”
C5, C6 = “Timer @2.00 Hours”
2) User may program each of the six contacts for one or more functions.
