Siemens MAMMOMAT 300 - Measuring the line resistance; Checking the line voltage in the generator

Siemens-Elema AB SPS-UD RX B7-120.033.01.10.02 MAMMOMAT 300
Solna, Sweden 05.98 65 02 186
7-2 Mains connection and power supply
To achieve the full output, the resistance measured must not exceed the following values:
• 0.25 Ohm at 110 V (1-phase)
• 0.45 Ohm at 208 V
• 0.50 Ohm at 230 V
• 0.60 Ohm at 240 V
• 0.65 Ohm at 277 V
• 0.85 Ohm at 400 V (2-phase)
If the above values are exceeded, reduce the generator power in accordance with section
13 in this manual.
Checking the line voltage in the generator
1 If not already done, remove fuses F10 (1) and F20 (2) or, when single-phase supply,
fuse F10 (1).
Figure 2 Line voltage in the generator
2 Mains supply "ON".
3 Measure the voltage at fuse holders F10 (1) and F20 (2).
4 Check that the mains voltage agrees with the voltage plugged on transformer T10 (3)
and p.c. board D711 (4), located above line filter Z1 (5).
5 Mains supply "OFF".
6 Reinsert fuses F10 (1) and F20 (2).
