2.7 Power supply
The platform power supply can be used in the following machine models:
WMF 1500 S+; WMF 5000 S+, WMF 9000 S+; WMF 9000 F
Notes:
The power supply 154C spare part is shipped WITHOUT a mounting
bracket
The jumper J4 is not connected when shipped.
Important: If the jumper is incorrectly placed on 1 and 2, then the
machine can no longer be switched off
If the power supply is used for a machine with 115 V input, the jumper
J5 must be connected. With no jumper, the power supply is set to work
at 230 V
The power supply protects itself by shutting off in case of overcurrent or short circuit. To reset the power supply, the machine must be briefly disconnected
from mains power.
The power supply is generally set to 154C on the software side. USA machine versions are an exception. These MUST be set to 154C-US in order to comply
with USA regulations. The setting results in someone poorer output constancy for milk foam quality in the Dynamic Milk model.
