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

6 - 2
To achieve the full output, the resistance measured must not exceed the following values:
•
0.25
•
0.45
•
0.50
•
0.60
•
0.65
•
0.85
If the above values are exceeded, reduce the generator power in accordance to Chapter
13 "Checking the swivel-arm system" in this manual.

Installation and Start-Up
Mains connection and power supply
at 110 V (1-phase)
at 208 V
at 230 V
at 240 V
at 277 V
at 400 V (2-phase)
If not already done, remove fuses F10 (1) and F20 (2) or, when single-phase
supply, fuse F10 (1).
Mains supply "ON".
Measure the voltage at fuse holders F10 (1) and F20 (2).
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).
Mains supply "OFF".
Reinsert fuses F10 (1) and F20 (2).
Mains supply "ON" (Do not switch the system on yet).
Measure the voltage at transformer T1 (6) terminals 1 and 3, transformer T1 is
located under the line filter Z1 (5). There must be 195 V- 253 V between the
terminals.
Measure the voltage at the output of line filter Z1 it must lie within 195 V- 264 V.
