Siemens MAMMOMAT 300 - Checking the supply voltages

Siemens-Elema AB SPS-UD RX B7-120.033.01.10.02 MAMMOMAT 300
Solna, Sweden 05.98 65 02 186
Mains connection and power supply 7-3
7 Mains supply "ON" (Do not switch the system on yet).
8 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.
9 Measure the voltage at the output of line filter Z1 it must lie within 195 V- 264 V.
Checking the supply voltages
The correct supply voltages +5 V, +15 V and +24 V have already been tested in the fac-
tory. Only a visual check of the function is therefore needed.
1 System "ON".
2 Check that the following orange diodes are "ON" on p.c. board D704:
• V39 (+15 V)
• V38 (-15 V)
• V41 (+5 V)
• V40 (+24 V)
