Enter Groups

The competitors can be divided into a maximum of 99 groups. One group has to consist of consecutive
start numbers. If groups are entered, the rank is output within the group. A group evaluation can be
created for the ranking; a group start is possible (all group members start at the same time).

Attention: You should always leave some vacant start numbers in a group so that you can use them in
case of late entries.
2.10 Test Function – Checking the TdC 8001
The info display (7) shows the following picture as long as <TEST> is pressed:
The test function shows the state of the device. All 10 channels are always monitored regarding their
state (4. line). If a channel blinks, it short-circuited. For the channels 0, 3 and 6 the voltage is always
shown directly. Moreover, the voltages of the battery and the photocells as well as the power consump-
tion of the extender are displayed.
The channels 0, 3 and 6 should have in normal state (open) 5 V. At an impulse the voltage has to break
down to 0 V.
The battery has a voltage of about 7.4 V when fully charged. When empty the battery voltage is about
5.8 V. With this voltage, the device cannot operate anymore. A warning about the state of the battery is
issued at 6.8 V.
The stabilized voltage "photocell" that supplies the photocell(s) has to be about 5 V.
The power consumption through the RS485 interface (d) must not exceed 1 A. In case of a consumption
of more than 1 A the supply for the extender is turned off.
Performance test –
Check of a two-core cable at banana jack c0, c3 or c6
− Turn on TdC 8001 (g)
− Select any program
Go through start menu until the TdC 8001 is ready
−
− Keep <TEST> pressed
Info display (7) shows measuring's
−
− Measuring's of c0, c3 and c6 are important for the performance test
Shor circuit test:
Cable is open at the other end
−
Press <TEST>
−
Voltage at the measured channel must be about 4.9 V
