2. PREPARATION FOR USE
2.1
Power Supply
The Tachograph Programmer is powered from an internal rechargeable nickel metal hydride
battery pack. The voltage of the Battery Pack may be checked at any time by selecting Battery
Detect from the Diagnostics Menu - see section 2.6 (Diagnostics Menu – Battery Detect) for
details.
The 9.6V Battery Pack has a capacity of 600mA/hr. The idle current of the programmer is
approximately 30mA, rising to a maximum of 78mA when in normal use. Standard use of the
communications features results in a current consumption of around 45mA. The OFF state current
consumption is around 35 A, which maintains
the function of the Programmers internal
temperature compensated real-time clock. Based on these figures, a fully charged battery pack
should give a continuous power on time of approximately 13 hours. Assuming a badly degraded
battery, the programmer should have an expected worst case power-ON time of around 7 hours
before recharge is required.
2.1.1 Battery Charging
The battery is recharged using the AC charger supplied in the Programmer kit (illustrated as
Harness I in ANNEX A - ). When fully discharged, the battery will take approximately 14 hours to
recharge. The unit will then operate for at least 8 hours before requiring recharging. To conserve
battery charge, the unit will switch off automatically after 10 minutes of non-use (except when in a
bench test mode) or if the Voltage drops below 8V - the Critical voltage - below which tests can
become inaccurate.
The Programmer should
NOT
be continuously connected to the charger after an overnight
charge. This can greatly reduce the Batteries performance, and in extreme cases destroy the
Battery.
2.2
Connectors
The Tachograph Programmer has three connectors on the end of the unit above the display and
two others on the side and on the bottom, as shown on Figure 1 (see below).
A. 6-pin DIN socket for connection of battery charging unit, bench test leads, pulser leads for rolling
road or fixed distance calibration and Stoneridge VR8400 programming leads.
B. 4-pin DIN socket for connection of flexi-switch.
C. 8-pin DIN socket for connection of Stoneridge VR2400/SE5000, Kienzle 1319/ 1324/DTCO,
MotoMeter and Actia Smartach tachographs.
D. RJ11 Socket used for upgrading the Programmer Software version.
E. Smartcard Connector. Smartcards are capable of storing digital information so that the data
stored can be read by suitable electronic devices. The MKII Tachograph Programmer has a
smartcard slot which may be utilised in the future for a variety of uses including security.
