12.3.3 Equalise charging
Equalise charging prevents acid layering via controlled gassing and thus extends the service life of
the battery. The following applies in addition:
Q Equalise charging starts when the cycle has expired or the switch-on threshold
1)
is crossed.
Q Equalise charging stops after the charge duration has expired.
Q Equalise charging is switched on in the factory settings. Prerequisite: battery type = ’Lead acid
battery’.
Q After equalise charging, the controller automatically changes to float charging.
Operation
Q Generally switching equalise charging on/off: ’Main menu’
’Battery settings’ ’Equal.
charging cycle’ ’On/off'’
Q Cycle: ’Main menu’
’Battery settings’ ’Equal. charging cycle’ ’Cycle duration’
Q Switch-on threshold: ‘Main menu’
‘Battery settings’ ‘Charge voltages’ ‘Equal.
charging’ ‘Starting threshold’
Q Charge completion voltage: ’Main menu’
’Battery settings’ ’Charge voltages’ ’Equal.
charging’ ’Equal. charging voltage’
Q Battery type: ‘Main menu’
‘Battery settings’ ‘Battery type’
Q Charge duration: ‘Main menu’
‘Battery settings’ ‘Expert menu’
2)
‘Equal. charge dur.’
1)
Value in percent with SOC control, in volts with voltage control
2)
More information on this is provided in section 13.5 'Calling up the expert menu for battery set-
tings'.
12.4 Data logger
The data logger stores the following data in internal memory:
Q Energy input
Q Energy output
Q Min. battery voltage
Q Max. battery voltage
Q Max. input current
Q Max. load current
Internally stored data is shown on the display and can be deleted.
– Observe the manufacturer's specifications when setting the cycle and charge duration.
– Equalise charging is only possible if the battery type 'Lead acid battery' is set.
