Connect the starboard tab actuator black wire, or the Lectrotab interconnect cable green wire, to point 6. Connect the actuator white
wire, or the Lectrotab interconnect cable white wire, to point 7.
Remote Oval Wiring
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. Wire
as noted below, wherein all Ovals in the system, up to a total of 6, including the master, are electrically connected in parallel. Also, on
all remote Ovals, 12 or 24 VDC power needs to be connected to each one from any convenient source, to power the tab position
indicator LED’s and the internal microprocessor. Operating current, with all at points 1 and 2, LED’s lit, is 10 milliamps. Standby
current is about 6 milliamps.
*Early production wires were blue and orange. When mixing the two,
treat brown and orange as the same. Always connect blue to blue.
WARNING
Do not make any connection to the # 3 AUX terminal
or terminals number 4, 5, 6 or 7, on any remote unit. Only the
master has these five terminals connected. All remotes use only
terminals 1 and 2 and the communications, 2 pin plug.
Oval Operation
1.
Turn on the power at the vessel’s main panel to energize the trim tab system. There will be no response by the Oval control.
2.
Turn on whatever switch the boat builder or other installer has provided to energize the Oval control. Typically this will be a
dedicated switch marked “Trim Tabs” or the engine gauge or ignition switch. This will “wake up” the Oval and initiate a full
