VMT8000 series

4.2.1 Release contact (IGN)

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 / 48V 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. If the device is

installed onboard of vehicles or other mobile and battery driven equipment, the ignition function also

saves energy. This function can be configured by using the Ignition Key Locking software tool. For

example, the computer can be shut down in a time-controlled manner if voltage is no longer present at

the ignition contact. Prefabricated supply cables are available from ads-tec for using the ignition

function.

Recommendation for use:

Switching the device on or off by using the ON/OFF pushbutton 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 button. However, it can also be restarted by using the ON/OFF function

of the ignition.

ATTENTION

Hazard due to overvoltage

There is an acute risk of irreparable damage if the

permissible threshold is exceeded.

 Do not operate on vehicles that exceed the

permissible system voltage.

The following thresholds for system voltage must be observed:

24V DC system voltage

5V DC – 36V DC

48V DC system voltage

5V DC – 60V DC

Recommendation for use:

The ignition function must never be used together with the autostart function!

Recommendation for use:

The functional description of the program Ignition Key Locking can be found in the

chapter of the same name.
