FC1, FCDA & FCSR Flow Control |

FC1, FCDA & FCSR Flow Control
The FC1, FCDA and FCSR are NAMUR mount flow control modules for the Automax SuperNova actuator. The modules provide a compact flow control, allowing for precise adjustment of opening and closing speeds of the SuperNova actuator. The FC1 provides flow control in one direction, while the FCDA and FCSR provides flow control in two directions. The FC1, FCDA and FCSR may be sandwich NAMUR mounted with other Automax NAMUR accessories or may be used by themselves.
Installation Instructions
Automax sandwich NAMUR mount accessories are easily installed to the SuperNova actuator simply by stacking one on top of the other and bolting the entire stack to the actuator NAMUR mounting surface.
Orientation of FC1, FCDA & FCSR:
The FC1, FCDA and FCSR should be mounted to the actuator with the NAMUR ‘O’-ring grooves toward the actuator. The FCDA adjustment screws may be oriented either up or down. On a spring return actuator, the FC1 & FCSR must be oriented such that the adjustment screw is pointing up.
To Install:
1.Follow order of installation below in stacking accessories. If an accessory is not required, skip it and proceed to the next accessory.
Order of Installation:
a:LV1 Lockout and vent valve
b:FC1, FCDA or FCSR flow control
c:APS1 or APS2* air purge system
or NPT1* NAMUR-NPT adapter block or NPTELB NPT elbow adaptor block
d:A25N* solenoid valve
* One of these accessories should be the last accessory in the stack. The NPT1 and NPTELB block provides 1/4" NPT ports in cases where FC1, FCDA, FCSR or LV1 would be last accessory in the stack.
2.Properly orient NAMUR accessory (see appropriate IOM.)
3.Insert ‘O’-rings into ‘O’-ring groove on back face of accessory.
4.Mount entire stack to SuperNova NAMUR mounting face, using appropriate bolt kit shown in chart on back page of IOM. Apply Locktite Threadlocker 222 or equivalent to screws prior to assembly.

Operation
The FCDA functions as an exhaust flow control for the SuperNova double acting actuators. Free air flow is allowed into the actuator ports through a check valve. Exhaust flow is restricted by a needle valve, slowing operation of the actuator. For a direct acting actuator, the right screw controls CW speed, and the left screw controls CCW speed. For a reverse acting actuator, the left screw controls CW speed and the right screw controls CCW speed.
The FC1 functions as a single exhaust flow control for the SuperNova spring return actuators. The operation is the same as the FCDA except it only has one adjustment screw and only controls the failure speed.
The FCSR functions as a flow control for the SuperNova spring return actuators by independently restricting the supply and exhaust air flow of a common port. For a fail CW actuator, the right screw controls CCW speed, and the left screw controls CW speed. For a fail CCW actuator, the left screw controls CCW speed and the right screw controls CW speed.
Speed Adjustment
Turn adjustment screw CW for a slower speed, and CCW for a faster speed.
