7 AC Input:
Connection for line (utility) power input via the “TO UPS IN” cable from the Power Transfer Switch.
8 Serial Interface / RS-232 Connector:
This DB-9 female connector is used to connect the BBS2000 to a computer for remote control, monitoring and
calibration using HyperTerminal commands. Any standard RS-232 cable may be used (not included with
BBS2000). See Section 2.3 for more details about connection and use.
Note: The interface is opto-isolated and shares a common ground with the green control terminal block.
9 USB
Interface:
This USB connector is used to connect the BBS2000 to a computer for remote control, monitoring and
calibration with HyperTerminal commands. Any standard USB cable may be used (not included with
BBS2000). See Section 2.3 for more details about connection and use.
10 Green Control Terminal Block:
This 22 position terminal block provides communication with the intersection controller, controls the Power
Transfer Switch (PTS) and starts the self-test. Figure 7 shows its layout and operation.
Note: This terminal block is opto-isolated and shares a common ground with the Serial Interface.
Each of the six programmable contacts can be set for one of five functions listed below or be
disabled. The relay contacts are Form C type, i.e., each of the six programmable contacts has
Common (C), Normally Closed (NC) and Normally Open (NO) contact positions.
• OnBatt: Default setting for relays C1 and C2. Energizes when Utility Input line power is unqualified and the
inverter turns on to provide AC power from the DC batteries.
TIP: When the AC Input and Output Circuit Breaker is turned OFF, an auxiliary switch on the circuit
breaker opens which disables the On Batt. contact at the Green Control Terminal Block. This prevents the
UPS from sending a signal to put the intersection signal lights in flash if the UPS is NOT in service.
• Low Battery: Default setting for relays C3 and C4. Energizes when the battery string drops below
the programmed battery capacity. The default value is 47.5 volts which is approximately 40% Battery
Capacity.
TIP: You can change the preprogrammed value to match the batteries used and the actual operating
conditions. See Section 2.3.6.4, “Maintenance” # 35, “Battery Voltage Level % Capacity Remaining”.
• Timer: Default setting for relays C4 and C5. Energizes after the unit has been in Battery mode for the
programmed time. The factory default value is 2 hours.
TIP: The time can be programmed to be from 15 min. to 8 hours in 15 minute increments
• Alarm: Energizes on any alarm or a specific alarm.
• Fault: Energizes on any fault or a specific fault.
• Self-Test: To initiate self test, jumper the TB 19 & 20 at the Green Control Terminal Block.
TIP: It is much easier to initiate a self-test from the Control submenu on the LCD display touch
pad.
