3.5 OPERATION
Once the system has been properly installed, it is ready to operate. The following procedures
will explain how to start-up the system while wired into rated electrical power and also how to
start-up with no AC power available.
Normal Operation on AC Start-Up:
•
Verify that the unit is wired into properly rated electrical power through the Power Interface
Module (PIM).
•
The AC IN and DC IN cables must be fully connected to the unit. There is an interlock
system that will not allow the SP unit to operate if either of these connectors are open.
•
Position the DC breaker to the
ON
position.
•
Position the System Power Switch to the
ON
position.
The system will proceed through about a three-second diagnostic where all the lights will
sequence
ON
then
OFF
. The AC IN light will flash several times and the audible alarm will
give a short burst. The AC IN light will then stay
ON
once it acknowledges acceptable input
voltage and frequency. The battery level meter will light to at least an 80% level. The
INVERTER light will come
ON
and power will be available at the output receptacles.
Continuous power is available at the output receptacles from the inverter. If the inverter is
powered down or should malfunction, a bypass circuit will maintain power at this receptacle.
This bypass line is protected through the Bypass breaker.
Battery Operation after AC Start-Up:
•
Remove AC power from the system.
The AC ON light will flash. In
stand-by mode
, inverter power will be supplied to the PIM in two
timing steps to control the traffic equipment wired to the SP system, now powering the cabinet
in
flash
mode. In
continuous
mode, the cabinet operation will continue without interruption. A
small hourglass will be in motion within the HOUR METER.
If operation were to continue in this mode, the BATTERY LEVEL meter would start to turn
OFF
, one light at a time. If the unit is allowed to operate further, it will time out and shut off
completely. If power were to return, the unit will automatically restart and return to the
condition it was in at the moment it went into
Battery
Mode
.
Once power is returned, if in
standby
mode, inverter power to the traffic equipment will be
discontinued through the PIM in a sequenced timing operation. In
continuous
mode, the
cabinet operation will continue to operate without interruption. The EVENT COUNTER
METER will increment. The EVENT COUNTER METER can be reset by momentarily pushing
the RESET button located between the meters.
Total battery operation is recorded on the HOUR METER.
DC Start Operation (Cold Start)
If no utility power is available at the time backup power is required, the unit may be started to
accomplish abbreviated tasks. The limitations of the battery prevent extended operations at
full load.
•
Position the System Power Switch to the
ON
position.
•
Push and hold in the COLD START switch until the audible alarm beeps.
