31 OUTPUT SHUTDOWN
This allows output to be switched OFF or Shutdown. BBS switches to STANDBY
mode when this option is activated.
32 INVERTER ON/OFF
During ON BATTERY or STANDBY mode, this option allows the inverter to
switch OFF or turn ON after the user programmable delay time.
The delay can be user programmable in 0.5 second steps from 0 to a maximum
setting of 255 steps (128 seconds). The delay is only available in Standby or
Battery modes. When the unit returns to line mode, the delay resets to a default
of 0 seconds.
During a battery discharge or ON BATTERY mode, the operator can stop the
inverter immediately after the user programmable delay time of 0 seconds to a
maximum of 300 seconds, prior to making the intersection dark.

This option allows for the change of password. The factory set default password
is 1111.
Tip: Password can only be changed in line mode.
34 LINE QUALIFY TIME
When input power returns and it is qualified, i.e., it is within the acceptable range,
the retransfer from Battery mode to Line mode is delayed by user programmed 3
/ 10 / 30 seconds to insure the line AC is stable and prevent unit cycling. The
factory set default value is 30 seconds.
35 BATTERY VOLTAGE
LEVEL % Capacity
Remaining
The level for LOW BATTERY ALARM as well as the activation of Normally Open
relay contact on com port connector is set here.
The Voltage level is user programmable in 0.5VDC increments from 42VDC to 55
VDC. The factory default setting is 47.5VDC or 40%. The relationship between
remaining % capacity of the battery and its DC Voltage depends on the
characteristics of the batteries used.
