1.5.9 STM01 OUTPUT MONITORING BOARD
This board monitors the UPS output voltages. It accepts the 3-Phase AC output voltages at the UPS output
and generates a fault signal if there is a voltage or alternance loss in the outgoing sinusoidal waveforms.
A)
STM01 Board Connectors
- CN1 : The 3-phase and Neutral of UPS output voltages (the output of the SCR switches) are
connected to this socket. If any one of these voltages is too low (<160V AC) or has a high DC
component (probably resulting from inverter damage, bad connection or SCR failure etc.) then
a ‘’DC fault’’ signal is produced on this board.
CN1-1 : Neutral
CN1-3 : UPS output T-phase
CN1-5 : ‘’ S-phase
CN1-7 : ‘’ R-phase
- CN2 : When a ‘’DC fault’’ signal is produced, it is available on this socket. This is indicated by LD1
(yellow LED). CN2 is connected to CN9 of ADVS01-R1 board and the fault signal is
transferred to the main controller board (P3MC-R5) from ADVS01 board.
- CN3 : HF supply input
- CN4 : HF supply input

STM01 Board Test Points
- TP12 : +12V DC(+/-0.5V)
- TP : VREF1 = 7.7V DC (+/-0.2V)
- TP : VREF2 = 6.7V DC ( ‘’ )
