The WTT4 Wake Turbulence Timer and WTT5 Wake Turbulence Timer are designed to be mounted in a cutout in the control console, with a clear area of about 5" needed behind the cutout.  A stand-alone desktop enclosure is available for the WTT4 Wake Turbulence Timer if cutting the console panel is undesired.

Choosing A Console Location

For ease of use and maximum visibility, select the location in the console carefully. The ideal location for the timer is within easy reach of the controller, in the controller's field of view. The best viewing position is when the timer is within about a 45° to either side of the controller position and the timer is inclined less the 30° from the controller's line of sight.

The horizontal format WTT4 timer requires 6.5" x 4" of panel space, and will fit in a position that housed a AWTT3 timer. The vertical format WTT5  timer requires 4" x 5.5" of panel space. About 5" clearance behind the console panel is required. 

Cutting The Console Opening

The next step is cutting the required opening in the console panel. Links to full-size templates are provided below; please verify the scale after printing out the template. The bold dashed line shows were to cut. Note the corner areas - be sure to leave enough material for the mounting screws to hold. 

Caution: Be certain the area behind the selected location has about 5" depth clearance behind the console and the area is free of wires that might be snagged and cut.

Connecting The Power Supply

Power for the Wake Turbulence Timer is supplied from a 5 volt USB power supply module.  Locate a 120VAC outlet under the console near the Wake Turbulence Timer.  A 6' USB cable is supplied with the timer.  Plug the cable into the power supply module and route to the console opening. for the USB power supply module. the supplied USB cable is about 6-ft long. Plug in the module and route the cable to the console opening. The wake turbulence timer requires approximately 300 mA at 5 volts. 

A standard USB A - B (full size) cable is used to connect the timer to the power supply.  A longer cable may be used if needed.

Power up The Timer

Connect the USB cable to the timer to power it up. The timer will perform a lamp and beeper test for several seconds when power is connected. All segments of the LED displays will flash, the illuminated switches will light and the beeper will sound. If the timer remains dark, verify the 120VAC outlet has power, the USB module is securely plugged in and that the USB cable is properly connected. 

Mounting The Timer

Four #6 pan head screws are provided for mounting the timer. Secure the timer to the console with a screw in each corner.
