Type “0” Battery
With the battery set to type 0, the following menu is displayed:
(316Vmin,336Vp,354Vs) Prealarm : 5min
Adjustment: (4=setV), 7=-,8=+
When key 4 is pressed, the program proposes the setting of the three voltage values.
Vbat.test: Vmin., Vp, Vs: 316, 336, 354V
Adjustment: 3-4+, 5-6+, 7-8+
Preset value
With the three factory preset voltage values, the display panel may indicate an incorrect backup time
during discharge.
Battery type “0” setting
The three values to be set are linked to the
battery discharge regime
(relationship between discharge current /
battery capacity in Ah). Example: for a 100Ah battery with a discharge current of 100A, the regime is 1.
The three values, Vs, Vmin and Vp, are obtained from the discharge characteristic curve, supplied from
manufacturer, relating to the
battery discharge regime
1C has been determined:
Vs
start of discharge voltage
(1)
, intersection with the x-axis (battery terminal axis),
[the value must be multiply for 40, number of batteries]
Vmin minimum voltage value ( end discharge battery ), point of intersection with the dashed curve (if this value
is lower than Vmin* set up Vmin=Vmin*
(2)
.
[the value must be multiply for 40, number of batteries]
Vp
battery voltage with discharge at 90% of the total time
(3)
