Adjust Motor Control Module Selector
Switch
The Motor Control Module uses an 8-position selector
switch (S) to set system maximum working pressure.
See FIG.5.
The system must be configured to have a maximum
working pressure of 2000 psi (13.8 MPa, 138 bar). Set
the selector switch according to the following table.
The selector switch position will be properly set at the
factory for new systems. When a motor control module
is replaced, the selector switch must be set to the cor-
rect setting by the user prior to initial startup.
To set the Motor Control Module selector switch:

• Do not install components rated to less than the
maximum working pressure. Doing so may lead to
overpressurization and ruptured components.
• High-pressure fluid from ruptured components will
pierce skin. This may look like just a cut, but it is a
serious injury that can result in amputation. Get
immediate surgical treatment.
