3.2

Charger operation using the main On/Off control input

In order to activate the charger, a positive (high) signal must be applied to the main On/Off
control input while DIP switch 4 must be in the Off position. In a vehicle application, this is
typically the engine run signal. After a short delay of a few seconds, the charger will normally
start the charging process. There is however a second condition that must be met before the
charger starts the charging process and this is the input voltage level. The input battery
voltage must be above a certain level in order to allow the output battery to be charged.
Additionally, this condition must also be met for a preset amount of time. Please see the
table below showing all factory default voltage and time delay values that are stored inside
the Omnicharge DC charger:
1)

All parameters are configurable using the TBS Dashboard and Dashboard Mobile apps
As can be seen in the above table, there are two low input voltage turn off levels. The 'slow'
off level is allowed to be exceeded for a longer time than the 'fast' off level. This results in a
stable charge process while still avoiding a too deeply discharged input battery.
If the main On/Off control input is connected to the ignition- instead of an engine running
signal, while the turn off input voltage levels are set to relatively low values, please make
sure to start the engine in a timely manner to avoid discharging the starter battery too
much.
3.3

Charger operation without using the main On/Off control input

When there is no engine run signal available or when the charger must always remain
activated, DIP switch 4 must be set to ON. In this mode however, the input voltage
requirements as shown in the table of chapter 3.2 still applies. So the charger will only start
charging when these requirements are met.
