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.

II. INSTALLATION
A. Mounting Instructions
1. Refer to Figure 1. The series 90 is designed to be mounted
in-line with the major axis of the actuator. The air connections
for the series 90 should be on the same end as the air
connections for the actuator. The standard 39 actuator has its
air connections on the right-hand end cap (with the exception
of the line 0539 which has its air connections on the back) as
you face the actuator nameplate. The Series 90 nameplate will
be on the same side as the actuator nameplate.
2. If the actuator is double-acting, rotate the actuator shaft to its
clockwise position. Spring-return actuators will be in this
position already.
3. Place the mounting bracket on the actuator. Brackets to be
used with Series 90 positioner or controller packages may
have an optional indicating scale. This scale can be oriented
on either side of the actuator (depending on customer’s
preference), but normally will be located on the same side as
the actuator nameplate. Secure the mounting bracket with the
four (4) screws and lockwashers supplied in the kit.
4. Place the coupling over the actuator shaft. (Note: For the 05
and 1039 actuators only, shallow slot is placed over the
actuator shaft). Sizes 10-40 couplings have four (4) threaded
holes; two are ¹₄-20 thread for set screws and the other two
are #10-32 (located 45 degrees off the center line of the
coupling). The two #10-32 threaded holes must be on the
same side as the indicator scale (if any) on the bracket. The
size 05 coupling has two (2) ¹₄-20 threaded holes for set
screws only. DO NOT tighten the set screws at this time.
5. If the mounting kit is for a positioner or controller, an optional
indicating arm and locknut for the coupling may be provided.
If so, install this arm into the coupling and secure with the
locknut. The arm will point down and extend outside the
indicating scale mounted on the bracket.
CAUTION: The actuator is in its clockwise position (per step
#2). The indicating arm must be installed to allow rotation
of the actuator shaft in the counter-clockwise direction.
6. Place the Series 90 unit on the bracket while inserting the
shaft into the coupling slot. Be certain the holes in the bracket
and 90 housing are aligned and secure with the four (4) #1032 socket head screws and lockwashers provided.
7. The coupling set screws can be tightened after the actuator
has been cycled 90 degrees.
