MCA1215 – MCA2440 Connecting the device
8.5 Setting the DIP switches
You can adjust the device using the DIP switch.
S1 is used to set the voltage at which the device switches over from the
I phase (bulk) to the U0 phase (absorption) (also see chapter "Battery charg-
ing function" on page 47). S3 must be set to "OFF".
S2 is used to set the retention voltage. S3 must be set to "OFF".
When a battery sensor is connected, the output voltages is adapted to the
temperature for these two functions:
 MCA 12xx: –20 mV/°C
 MCA 24xx: –40 mV/°C
S3 activates the power mode when either S1 or S2, or both, are set to "Off".
In power mode, the short circuit, overvoltage and overheating protection are
controlled by the internal sensor.
When S1, S2 and S3 are set to "On", then the function control by external
devices is activated. Among others the type of battery and the charging volt-
age are set using the external device in this mode.
S4 regulates the fan function. When S4 is set to "On", then the fan is switched
to sleep mode (noise-reduced mode). When S4 is set to "Off", then the fan is
not regulated.
