SRL-20 Servoreeler ®
Installation and Operation
TEST RUNNING: We urge you to test run these Servoreelers® prior to installation. The reeler is designed for operation in a vertical
position; when test running, hold the SRL-20 in a vertical orientation with the cable exit point facing down. A minimum payload weight
of approximately one (1) ounce is required for proper down feeding of the cable. A standard XLR cable connector provides this
minimum ballast. An internal spill sensor is employed to stop the reeler if it is operated with too light a payload or with its cable
impeded from down feeding freely; This interlock is designed to prevent internal cable spill resulting in jamming the mechanism. This
safety interlock may not offer adequate protection if the unit is operated horizontally. Please note that this interlock is a back-up
system, it is prudent to avoid conditions that would overly rely on its intervention.
MOUNTING: The SRL-20 is provided with a 4.25” x 8” mounting hole patern on its rear surface. These holes are threaded to accept
¼-20 machine screws.The frame of the reeler is machined aluminum plate, some care is advised to avoid stripping these holes.
Prior to installing try the machine screws by hand to assure a proper fit. Screw length should be selected so that no more than a
nominal one half inch (.5 extends into the rear plate. Two or more of these mounting holes must be utilized for mounting.
C A U T I O N Professional care and judgement must be exercised when mounting equipment overhead. Mounting screws
must engage a permanent, solid structural member or a metal bracket that is in turn securely attached to such a structure. Should
mounting against a wood beam or surface be required, sheet rock or wood screws may be employed from the inside, through the
threaded holes into the structure. (to remove the cover, loosen the four cover screws about two turns and slip the cover up from the
body of the reeler.) In this case all four holes must be used. Install washers so that the center of the reeler frame is elevated clear of
any irregular or high spots.
Please note, the installer and the purchaser must assure that these devices do not pose a hazard to others, both during and
after installation. Architectural or engineering guidance is highly recommended to help assure a safe installation,
consistent with the particular physical requirements of your project.
OPERATION:
power. Operation is initiated by either pusbutton control or through interface with an external computer control system like AMX or
Crestron. IR sensors are employed to provide empty and full limits. An adjustable operating stop is also provided. This adjustable stop
operates from the deploy mode. After this preset stop is reached, re-start with a sustained down command to reach a lower “service
level”. Automatic or incremental operation is selectable. The automatic mode provides locked-in operation that is initiated by a single
“Deploy” or “Retract” momentary signal. The incremental mode facilitates fine positioning by allowing the Servoreeler® to respond to
individual, incremental, commands. Test running as described below, should always be performed in the incremental mode.
SETTING OPERATING STOP POINT:
module and track. To access this adjustment; loosen the four cover screws about two turns and slip the cover up from the body of the
Reeler. To the middle right of the cable storage reel, you will see an aluminum track with a guide slot in the middle. An adjustable
module is set into this slot with a thumbscrew. The Reeler is shipped from our factory set to maximum deployment. To reset, loosen
the locking thumb screw just enough to enable the module to slide; utilizing the left edge as a pointer, push on the bracket utilizing firm
finger pressure to re-locate the sensor to a new position. Retract above this point then re-activate the down mode to test the new stop
point; repeat until desired length is achieved. Final positioning may require very slight movement of this module. Gently tighten the
thumbscrew to retain the setting. Excessive force is not required and should not be used when tightening. This pre-set stop position
will take place from the down mode. Unless configured as a final stop, this position may be bypassed to reach a lower service position
by applying another sustained down command signal.
this reach does not exceed the physical height limits of your facility and permit the microphone to collide with a surface.
OPERATIONAL CAUTION: When handling the cable after installation, DO NOT pull on the cable exerting a force greater than the
normal payload weight. Never exceed 10Lbs (4.5kg) of pull on the end of the cable. Non-linear or excessive pull force of the cable
will distort the concentricity of the cable pack on the storage reel. This will adversely affect the operation of the IR sensors. Should
this occur, cable pack concentricity, can be restored by fully deploying and then retracting the microphone cable with its normal
payload.
Servoreelers® are operated by a remotely located controller. SRC controllers provide linear regulated 24vdc system
The IR sensor that controls the length of cable deployment is mounted on an adjustable

Maximum deployment of this Servoreeler® is about 25 ft; verify that
