the charger will be forced to change-over to “Stage 3 or Float / Maintenance Charge Mode
(U Phase)” after elapse of 4 or 8 hours determined by the selected duration of the
timer circuit. The battery will be charged to approx. 95% of its capacity by the end
of this stage. Ideallyit would be at 100%, but there are some practical limitations like
temperature effect etc thatusually prevent full recharge.
During this Stage, following LED indications are provided:
• Charging Indicator LED (4) on the front panel turns orange
• Yellow LED under “Uo Phase” is lighted on the Remote Panel (15) ( Optional accessory)
NOTE: The threshold of current for change-over between the Absorbtion / Boost
Charge Mode (“Uo” Phase) & the Float / Maintenance Charge Mode (“U”
Phase) are different as follows:
SEC-1245E SEC-1260E SEC-1280E SEC- 2425E SEC-2440E
•
From “Uo” Phase to “U” Phase 4.5A+/-0,5A 6A+/-0.5A 8A+/-0.5A 3A+/- 0,5A 4A+/-0.5A
•
From “U” Phase to “Uo” Phase 9A+/-1A 8.5A+/-1A 10A+/-1 A 7A+/-1A 5A+/-0.5A
Stage 3 – Constant Voltage, Float or Maintenance Charge Mode (U Phase):
During
this mode, the charger outputs a constant voltage U = 13.8 V (SEC-1245E, SEC-1260E
and SEC-1280E) or 27,6 V (SEC-2425 and SEC-2440E). This helps in maintaining
full capacity of the battery and also provides replacement charge to overcome self
discharge of the battery. The battery canremain connected in this stage indefinitely
without the risk of discharging.
During this Stage, following LED indications are provided:
• Charging Indicator LED (4) on the front panel turns green
• Green LED under “U Phase” is lighted on the Remote Panel (15) (Optional accessory)
CAUTION!
3 stage charging is recommended for charging stand-alone unloaded batteries
(there is no loadconnected to the battery when it is being charged). If a load is also
connected simultaneously,a part of the charger’s output current will be diverted to
this load. Thus, the charger may remain locked in Stage 2 if the current drawn by
the load is more than the preset value of threshold current determining change
over from Stage 2 to Stage 3 .This will lead to overcharging and loss of electrolyte.
For charging a battery when a load is also connected simultaneously, Stage 2 voltage
should be same as Stage 3. Select “Loaded Battery” with the help of DIP Switches
(5) – See under“Selecting the Type of Battery and Charging Stages”.
