I
GNITION FUNCTION
The device is capable of being externally started by using an additional signal input. This
function is well known from the automotive industry (switch-on by using an ignition
contact). The device is here continuously supplied with a 24V DC power supply, and only if
the additional signal is present at the ignition contact, e.g. as a result of turning the
ignition key of the forklift, the computer is switched on or the blocking is released. This
function protects the system from unauthorised use, and saves energy by using the
battery of the vehicle only in connection with the vehicle being used, at the same time, if
the device is installed onboard of vehicles or other mobile and battery driven equipment.
This function can be configured by using the Ignition Key Locking software tool. It
allows you, for instance, to shut down the computer after expiry of a timer once the
voltage is no longer present at the ignition contact. Preassembled supply cables that allow
the use of this ignition function are available from ads-tec.
Note:
Switching the device ON or OFF by using the Power button will override the ignition
function. That means, if the device is switched off by using the Power button, the system
is shut down and can be restarted by using the Power switch after that, but can then also
be restarted by using the ON/OFF function of the ignition.
Warning:
The ignition signal works with a threshold value of 5V DC. The voltage must never exceed
the maximum voltage of 36V DC! Risk of destruction!
Do not use the device onboard of vehicles with more than 24V DC system voltage without
any voltage adaptation for the ignition contact! Risk of destruction!
