Chapter 4 Control elements and displays
4.1 The EFAS tachograph
The EFAS has a two-line LCD display, two slots for tachograph smart-cards, a front-mounted interface for calibration and down-
loading, a printing module, and 6 operating keys. It can be installed in a standard-sized car stereo slot. Warning alerts can be
emitted optically and acoustically.
The EFAS is activated when
y the vehicle's ignition is turned on,
y by signals from the motion sensor,
y
when a tachograph smart-card is inserted,
y
when any of the keys is pressed or
y through an FMS download,
y at the end of a 45-minute drive break.
To remove the tachograph card, the vehicle must be stationary (0 km/h) and the ignition turned on (level 1). At the latest
4 minutes after the ignition is switched off, EFAS switches off automatically. If a key is pressed after turning off the ignition, the
shutdown of EFAS is delayed by up to 4 minutes. The time for EFAS to switch off after switching off the ignition can be configured.
