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 "Battery charging func-
tion" on page 46). 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 "Off", then the remote control is activated. The
type of battery and the charging voltage are set using the remote control 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.
