4.3 Programming of system configuration parameters

The system configuration parameters are protected by a password because most of

them are critical for correct operation of the system.

Wrong programming can for example destroy the battery or cause loss of

output voltage during operation!!

4.3.1 System configuration parameters

Parameter Setting* Comments

Isolation trafo utility YES, NO YES if optional input isolation transformer is

present

Isolation trafo output YES, NO YES if optional output isolation transformer is

present

Delta soft start time 1, 10, 20, Input current switching in ramp function.

40 secs. Higher values used together with smaller/

unstable diesel generators

External SSW present YES, NO YES for systems with external static bypass

switch

Normal charge voltage 438 Setting of float charge voltage at 20°C /68°F

(Aut. compensation for deviations)

Boost charge voltage 438 Setting of boost charge voltage at 20°C /68°F

(Aut. compensation for deviations)

Low battery warning 346 Warning for discharged battery

Low battery shut down 326 Switches off the system at min. permissible

battery voltage

Synchronization 0.25, 0.5, 1 Synchronisation speed. Higher values used

2, 4 Hz/sec with very unstable utility frequencies

High battery temperature 15-40°C Alarm for too high battery ambient

/59-104°F temperature

35°C/95°F

Common fault delay 0, 10, 20 Delay before the common fault alarm relay is

30 secs. activated

Reset operation mode YES, NO YES resets system locked in bypass or battery

lock operation mode caused by system failures

(Only for service personnel)

Highest station address 2-9*** Highest station address in parallel system

Station address 1-9*** Station address in parallel system

Advanced power None*** Only used in parallel system.

management (APM) Off: Advanced power management disabled.

Parallel +1: Redundant operation with all units

in operation.

Redundant +1: Redundant operation with

one unit being inactive in parallel system

APM test mode active YES, NO*** YES, if APM test mode is active (service

personnel only)

Battery connection Common, Common if common battery is used in parallel

Separate system. Separate if separate battery is used

Expected back-up 0,1-999,9 Expected back-up time for UPS in minutes,

time [min.] 5,0 when running at 100% ohmic load.

Time used by the ABM**

Battery capacity 0,1-999,9 Total battery capacity in Ah.

in [Ah] 7,0 Setting used by the ABM**

Programming parameters

** Advanced Battery Monitor

*** Viewable only in a parallel

configuration.

* Text in bold letters are the

factory standard setting

NOTE:

Common battery pack is a

technical possibility.

However, APC recommend

separate battery pack due to a

higher safety degree in con-

nection with redundant/parallel

operation.

The UPS system is prepared

for both solutions.
