Checking The Line Voltage In The Generator - Siemens MAMMOMAT 1000 Nova Installation And Start-Up Instructions Manual

6 - 2
To achieve the full output, the resistance measured must not exceed the following values:
•
0.25
c
•
0.45
c
•
0.50
c
•
0.60
c
•
0.65

If the above values are exceeded, reduce the generator power in accordance to
Chapter 14 "Further programming" 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
Fig. 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
5. Mains supply "OFF".
6. Reinsert fuses F10 (1) and F20 (2).
7. Mains supply "ON"
8. Measure the voltage at transformer T1 (6) terminals 1 and 3, transformer T1 is
9. Measure the voltage at the output of line filter Z1 it must lie within 195 V- 264 V.
