7 Installation

7.1 Optional: Activate bypass function

The bypass function (permanently ON) is used to charge the starter battery

with the auxiliary battery if the voltage of the starter battery is too low. The

voltage detection through PIN 5 (GND) is deactivated so that the CDR distrib-

utes charging current at any voltage.

To use the function, carry out the following step:

1 Switch the plug contact PIN 4 to ground.

ð The function is activated.

An external LED can be connected and used as a remote display to detect

whether the device is conducting current.

To install the function, perform the following step:

NOTE! External LED: Output 5 V, max. 5 mA. Not included in the scope of de-

livery.

1 Connect the plug contact PIN 1 to the input of an external LED.

2 Connect the other terminal of the external LED to ground.

ð The function is installed.

The CDR can distribute the charging current both bidirectionally and unidirec-

tionally. The factory default setting is bidirectional charging current distribu-

tion in two directions.

To change the direction of the charging current distribution to unidirectional,

carry out the following step:

1 Switch the plug contact PIN 2 to ground.

ð The charging current distribution is unidirectional from screw terminal 1 to

screw terminal 2.
