2.9 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).
Input groups? YES F1 If you do not want to enter groups
NO < F2 press <NO> or <F2>; if you want to
Enter groups press <YES> or <F1>
Continue: ENTER
and <ENTER>
GROUPS: Gr 1: 1 > 0 Enter the last start number of each group
as first start number of the following group
the next start number is automatically shown.
Save with: ENTER
GROUPS: Gr 1: 1 > 60 1. Group from StNo. 1 to 60
Gr 2: 61 > 90 2. Group from StNo. 61 to 90
Gr 3: 91 > 120 3. Group from StNo. 91 to 120
Save with: ENTER Gr 1: 121 > 0

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:
C0 = 4,9V battery = 7,3V
C3 = 4,9V photocell = 4,9V
C6 = 4,9V extender = 0,00A
# # # # # # # # # #
c0 c1 c2 c3 c4 c5 c6 c7 c8 c9
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 the two-core start-finish connection
:
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
