Elkhart Brass Sidewinder 7100 EXM Monitor - Manual (Page 19)

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