-USYS: System voltage measured by R 11 card at the load output

- I SYS: Total load current, calculated out of 1,2,3 or individual current by configured menu 38 in config if configured 1 load group this menu page does not appear

- PSYS: Total power of system

- Tamb, Tbatt: 1- Temp display only if "temp compensation" is enabled 2- Trip 1 or trip 2 is tepm controlled 3- If temp2 is also configured the ambient temp is displayed alternating with the battery temp

I BATT: 1- Total battery current 2- Not display if battery shunt or battery string is not configured

U BATT1 AND UBATT 2: 1- Individual voltage for two battery string 2- Second battery voltage is not displayed if string 2 is disabled so ubatt will display (- - -)

UDIFF1 AND UDIFF 2:

If middle point is config (menu 15) display wil l change in 2 seconds between ubat and udiff Udiff difference between first and second half of battery string

Battery cap: Shows the remain capacity % format during battery test

I RECT: Calculate current coming from all rectifiers IRECT = ISYS + IBATT and page is not displayed if Battery shunt or battery string is not configured

٢

CHARGE MODE: Display mode of charge and discharge

ALARM: Show list of currently active UA, NUA, MF alarms

2- Protocol Menu 1- When an alarm appears or an even occurs in the system, a log entry is made in protocol With (time, source, type) of alarm

2- If alarm disappears, 2nd entry with time is alarm source and word ok Date format 080105 --- 5 January 2008

3- Last 30 entries stored in volatile ram 4- Most 5 most recent of last 30 are stored in non volatile eeprom

3- General Menu Alarm stop 1- when activated, some alarms are not forward via relay o/p to remote alarm panel

2- However alarms remain indicated on red led on psc1000 3- State of (active / not active) indicate with red alarm (AS) 4- If configured so forward via relay o/p AS

Protocol clear Clear all entr ies in alarm protocol except star t entr y

Languages select language of menus

Default par recall activate default parameter which are predefined by software

Current par save any change in parameter must be saved otherwise will be lost at power down

Alarm test if configured to automatic all alarm led activated for 2 second one after other finally all active again for 2 sec and if configured to manual check alarms by Activated and deactivated one by one using ↑↓

Date & time to adjust date and time

4-Alarm menu Us max: upper NUA level of system voltage usys level is TC float charge when level is passed, NUA is activated after 2 sec

Us min: lower NUA level of usys

Ua max: upper UA level

Ua min: lower UA level

Dc low (AS& MF) relay o/p (base voltage)

Dc ok upper level for under voltage indicator on mf or as voltage is rising above level dc ok , the protocol entry dc low ok after dc low with time and date is generated

٣

Isys max max system cur rent if isys r ises above isys max UA or NUA is suppressed according to configuration

Isys min min system cur rent

MF delay for ex if you configured mf additional MF+UA ---> when mains failure display will Show MF, UA, IF you configured MF add to MF delay display will show MFand then Will dealy a delay time in setting to appear UA due to low voltage

Psys max max system power if system power r ises above psys max NUA OR UA is generated

If Isys ↑80% I fuse max -- NUA If Isys ↑I fuse max -- UA

If Temp ↑Temp high for at least 20 sec --- NUA if temp drops below Temp ok again configured alarm is reset

I fuse max

Temp high

Temp ok

5-Usys menu 1- usys 20C : float voltage at battery temp 20 C

2-Uset RM: set value of rectifiers

3- I batt max: total charging battery cur rent

6-Temp comp menu Appear only if external control or configured enabled

Tcoef Usys: temp compensation coeff icient in – mv/ c System voltage = usys@20 C + (Tbatt – 20 C)

7-Boost charge menu - charge current more quickly - start as soon as I above I start - stop as soon as I below I stop - Boost charge is forced to stop at latest 16 hr

Start Criteria: 1- Ibatt > Istart 2- Battery is not marked faulty 3- Last boost charge was more than 24 hr ago 4- I stop > 0 5- Neither equalize nor separate charging is active

Stop criteria: 1- I batt < I stop 2- System voltage > usys@20C for more than 16 hr to prevent bad battery from being

charged for ever 3- I stop = 0 4- Separate charge is active

Note: during boost charge, NUA is suppressed due to low / high usys and stop as soon as usys = usys @20

8-Battery Test menu

1- Battery fully charged 2- Rectifier stops delivering current and full load current from battery 3- Rectifiers are kept on support voltage so in case of battery failure Usystem doesn't dip below

This voltage

"Principle"

Note: -Test end as soon as battery has performed for the duration test or discharge capacity - Test Failed if usys ↓ U support or I diff > certain value with test

Start Criteria: 1- Test interval expired 2- No alarm 3-Battery full charged 4- Last mains failure at least 7 days ago 5- Neither equalize, separate nor boost charging is active

Stop criteria: 1- Duration expired 2- Faulty battery due to Usys low 3- I Diff > certain value 4- Battery fuse is blown 5- AH has been disharged

Function of card

R11: -This card used to measure the value of usys and isys, measure the voltage between load bus bar and

Divided it by constant resistance to measure the current

- send calculated value to contr oller via cobomo card - Sense with load circuit breaker if on or off

Note: if this card is faulty, controller will appear (** *) and Isys can't be measured

R12: -This card used to measure the value of ubatt and ibatt, measure the voltage between battery bus bar and Divided it by constant resistance to measure the current

- send calculated value to contr oller via cobomo card - Sense with battery circuit breaker if on or off

Note: if this card is faulty, controller will appear (- - -) and Ibatt can't be measured

A16: -Is LVD driver card, its function is to invert the control signal from the controller to LVD trip - socket X1 connected to socket trip1 in cobomo
