The Ps1501vi, Ps700vi, PS6000, PS6002, and PS6003 and strainless steel version UPS are microprocessor controlled and is capable of RS-232 communications through a
computer interface port at its rear panel. When combined with power management software and a serial communications interface cable, the PS6000 ups allows flexibility in
controlling UPS operation via computer. Using power management software, the user may customize automatic battery test intervals, upper and lower transfer voltage, utility
failure sensitivity, output voltage (220/230/240 Vac units only), low battery warning intervals, audible alarm delays, shut down delays, turn on delays and battery capacity
dependent restart settings. In addition, the UPS's readiness to supply power during a utility failure may be determined. Power management software can monitor the UPS's
battery voltage, available battery capacity and available run time (in minutes) as well as power quality related parameters such as line voltage, line frequency, output voltage
and output load.
APC software is utilized by the PS6000 it offers a full range of power management software for use with all members of the PS6000 -ups family.
Updates are available .
2.1
Battery replacement indicator and battery tester
The PS6000 -ups provides an indication when the battery needs to be replaced. It gives an indication of the battery's ability to provide sufficient energy during failed utility
conditions.
Every UPS is likely to require a battery replacement during its service life. The PS6000 ups systems indicate the need for battery replacement before it is discovered that the UPS
fails to provide the expected run time during a power failure.
The PS6000 Smart-ups's replace battery LED indicator shows the result of an actual load test on the battery. By exercising the UPS's battery during the self-test routine, the
PS6000 Smart-ups is able to detect a weak battery before it is required to support the load. In applications where the PS6000 Smart-ups is not turned on and off frequently or
where the UPS is left operating unattended, the UPS can automatically conduct this self test every 14 days. Power management software can also warn of replace battery
conditions and can be used to defeat the automatic self test or reduce the test interval to 7 days.
The on-line indicator lights when the UPS is supplying utility power to the loads. The on-battery indicator comes on when the UPS is supplying battery power. The replace
battery indicator lights when the UPS's battery can no longer provide approximately 60% of its rated run time. The overload indicator lights when the loads connected to the
UPS exceed the UPS's power capacity. The SmartBoost and SmartTrim indicators light when the UPS is correcting either a low or high utility voltage.
2.2
Diagnostic features
On startup, the UPS by default performs a self-test routine that verifies its readiness to supply power derived from the battery during a utility failure. Diagnosis of line voltage levels can be achieved by
using a feature in which the front panel display is transformed into a utility voltage meter. The PS6000 Smart-ups becomes a complete power quality logger and analyzer when used in conjunction with
power management software. On 120 Vac models only, the PS6000 Smart-upS.
2.3
Available run time calculation
The PS6000 Smart-ups's available run time in minutes may be monitored using power management software. The available run time changes with respect to the
UPS's available battery capacity and output load. In addition, the PS6000 Smart-ups keeps track of changing battery performance and adjusts the available run
time indicated for a weak battery nearing the end of its service life. When operating on-battery, the available run time is decremented as the battery capacity is
exhausted. This valuable information allows a user to decide when to save files and gracefully close operations. PS6000 Smart-ups also provides an indication of
expected run time when the UPS is operating on-line.
2.4
Configurable low battery, shut down, and restart intervals
Because shut down and file saving routines can take longer than the default 2 minute low battery warning interval, the PS6000 Smart-ups offers a choice of
extended intervals up to 10 minutes via power management software and the rear panel sensitivity switch.
Many computer networks that issue UPS shutdown commands are unable to do so as the last part of a shutdown routine. In these cases, it is up to the UPS to
provide some delay before actual shut down to allow the network to finish the shutdown routine. The PS6000 Smart-ups's shut down delay in response to a
shutdown command can be extended from 20 seconds to as long as 10 minutes using power management software.

Battery Charging
The battery voltage is maintained at a constant "float" level for maximum battery life and minimal heat dissipation. The UPS's battery charger operates continuously whenever the UPS is plugged in
(invertor always on)and the utility voltage is within normal limits. The time required to recharge the batteries to 90% of their full capacity following complete discharge of the UPS into a load 50% of
rated capacity is typically within 2-4 hours.
