Pictured above is the SETR-50 with black switches on a gray background. The SETR-51 is identical except for the color, wherein it
has black switches on a black background. The actual size is about 4" wide, 3 ½" high and ½" deep.
Thanks for your interest in the Lectrotab model SETR-50/51, Sealed Electronic Trim and Retract system, with tab position indication.
The SETR-50/51 "Oval" is either a stand alone or multi-station, software driven, microprocessor based control, featuring positive
click switches with integrated LED position indicators, in a single waterproof unit. The SETR-50/51 "Oval" is unique in that no
position feedback device is needed in the actuator. Also unique is the single component design of this control; no other interface box
or components are required for operation, and all connections are made directly to the back of the control.
Multi station capable, supporting up to 6 Ovals in the same trim tab system wherein each Oval is a full function control
with no switchover requirements.
High current outputs; 20 amps for both Port & Starboard actuators.
Mirror operation at all Ovals; simultaneous use at different stations is OK.
Independent control of Starboard and Port actuators.
Eight LED's, operating sequentially, indicate the position of each tab.
Automatic dimming for night operation, with each Oval dimming independently.
Salt water hose down proof and UV protected.
Ergonomically designed keypad for "Heads Up" operation with tactile feed back switches.
Any Oval can operate as the master control or as a remote; therefore, only one model is required. Expanding a single
station system to multi-station is a simple add-on with no changes to the original control.

Summary of Contents for Lectrotab SETR-50

  • Page 1 Trim Tab Control Pictured above is the SETR-50 with black switches on a gray background. The SETR-51 is identical except for the color, wherein it has black switches on a black background. The actual size is about 4” wide, 3 ½” high and ½” deep.
  • Page 2 To power the position indicator LED’s, local D.C. power, at about 10 milliamps, needs to be connected to each remote. • The SETR-50/51 Oval may be used on 12 or 24 VDC systems. • Indicators are programmable for use with 4 to 12 second stroke time actuators. Cannot be used with most popular hydraulic trim tab systems.
  • Page 3 With the Oval, no interface module is used. See the mechanical portion of the Lectrotab installation manual through the top of page 7. Instead of wiring to the manual switches as shown, connect directly to the back of the Oval using ¼”...
  • Page 4 After the initial “Oval” has been installed and tested, up to 5 more “Ovals” may be installed as remote stations. For each Oval, one Lectrotab communication wire assembly, part # SR, will be needed. This is an 18” two conductor wire, blue and brown,* with a special plug on one end which plugs into the Oval’s communication port on the back side of the control, to the right of point 5.
  • Page 5 Alternative Wiring and Operation Per the industry standard, set by most U.S. trim tab manufacturers some years ago, the Lectrotab control switches are set up to be pushed directly according to what the helmsman needs the boat to do. If the bow is high, push the upper portion of both switches DOWN to make the bow go DOWN.
  • Page 6 “Oval” would initiate full tab retraction and shut down. This scheme would provide tab retraction upon reaching the docking area instead of waiting for engine shutdown. With some thought, other interesting options for controlling point 3 may come to mind.
