Lectrotab Trim Tabs

FIG 3855

This electro-mechanical (no oil) concept offers a non-hydraulic trim tab actuator which cannot corrode, requires no maintenance, is
permanently sealed and will operate with a fouled ram. The positive "stop and lock" drive mechanism allows precise positioning and
absolute lock against tab deflection when backing down or when tab is used as a boarding step.

TI8B Round Tab Position Indicator 2-1/4" in diameter. Eight LEDs indicate port and starboard tab posi-
tion with all eight lit for tabs fully down. Indicator operates on a time basis and does not require a feed-
back transducer or special actuator. Can be retrofitted to any Lectrotab installation. One piece design fits
in 2" hole. Gauge is rainproof. Display automatically dims at night. Automatic calibration of the indicator
is initiated whenever power is turned on or off.

provide an "instant stop" circuit when the switches are released, thus preventing actuator over-run. This
control can be upgraded with an LED tab position indicator. The gasket sealed switch is designed to pre-
vent water entry. The control switch is self-contained and does not require an additional control box.
Switches are available for single or dual station applications. Operates up to 2 actuators per tab on 12V

SETR61 is a microprocessor-based trim tab control and trim tab position indicator incorporating tab
retraction and automatic calibration of the indicator whenever the control power is switched on or off.
Display automatically dims at night. This control is self-contained (no remote electronics enclosure) and
mounts over a 2" diameter hole 3-3/8" height by 4" wide. Most importantly, this control is completely
sealed, waterproof, front and back, and will not deteriorate in sunlight. Handles up to two actuators per
