

Calibrating Vertical Rotation - The Vertical calibration point is factory set at 90° (straight up). This

is the position needed when wiring for extended travel, or when using a Position Feedback

Display. This calibration will establish the highest vertical travel point of the monitor and allow

rotation in the downward direction the total range specified during system calibration. This

differs from the horizontal rotation calibration where the zero point is in the middle of the rotation

range.

Using the UP & DOWN controls, position the monitor such that it is aimed directly vertical or

at the uppermost limit of travel specified during system configuration.

Press and hold PRESET and then press and release the UP button. (On the joystick, hold

PRESET and pull the stick back and release). The status LED on the monitor should blink then

turn solid.

Release the PRESET button. The vertical axis is now calibrated.

Exit Setup Mode and check the monitor’s rotation limits. The monitor should not hit itself or

other objects. Recalibrate the EXM system if needed.

Caution:

If the vertical zero point is set too far forward, the monitor may be allowed to

crash into itself at the lower points of vertical travel. BE CAREFUL NOT TO MOVE THE
MONITOR INTO OBSTRUCTIONS OR ITSELF as this will cause the monitor motors to
over current. The monitor may need to be manually reversed if this occurs.

Calibrate Valve

NOTE: LEDs flashing above the closed & open buttons on an input controller indicate that the valve

has not been calibrated.

If an Elkhart Brass Unibody valve is being used in your system, calibrate it at this time by first placing

the valve in a half open position, and then pressing and holding the CLOSE and PRESET buttons on

any controller until the valve calibration begins. Allow the valve to complete all movements (closed,

opened, closed) before entering additional commands to the system.

Calibrate Position Display
Move monitor vertically to both upper and lower limits of travel, then left and right limits of travel. This

will calibrate the position display. Dimly lit LEDs will show maximum allowed travel, and the brightly lit

LED will show monitor position within the allowed travel. Changes to the travel limits will require

recalibration before new limits will be displayed.
