2 Modular Accessory System (Series 90) 07334-F
I. INTRODUCTION
The MODULAR ACCESSORY SYSTEM SERIES 90 (OR 90 M.A.S.) is
designed to provide a wide choice of valve position feedback and
pneumatic valve actuator control functions. Applications range from
simple end-of-travel limit switch indication to automated control using
feedback from a system parameter sensor (temperature, flow rate,
etc.). Maximum ambient temperature is 110°F for models with
solenoid and 160°F for models with electronics and no solenoid.
The concept behind the unit is flexibility, allowing the user to
customize a M.A.S. for a particular application. For this reason, only
individual installation instruction sheets pertaining to the specific
options being used are combined with this Installation, Operation
and Maintenance Manual. Please note – this unit is a complex
device and not all options can be accommodated simultaneously. A
table summarizing the available options follows. Note that the
presence of the POSITIONER or CONTROLLER options changes the
list of available options. Certain options also require the addition of
a second terminal block which will be provided in the M.A.S. unit or
kit when required.
a WARNING: The series 90 M.A.S. is an electromechanical device
subject to normal wear and tear. Its life is dependent upon
application and environmental conditions. Breather/Drain fittings
are recommended for humid environments when moisture may
condense inside the sealed M.A.S. housing.
CAUTION: Flowserve recommends that all product that must be
stored prior to installation be stored indoors, in an environment
suitable for human occupancy. Do not store product in areas where
exposure to relative humidity above 85%, acid or alkali fumes,
radiation above normal background, ultraviolet light, or
temperature above 120°F or blow 40°F may occur. Do not store
within 50 feet of any source of ozone.
M.A.S. MODEL: The M.A.S. product code per the appropriate options is
marked on the name plate as the M.A.S. model
number, with the exception of the voltage rating (if
any) and product revision level (R#). Voltage rating and
R# are marked in separate locations on the nameplate.
