Limit Stops Setting (Autopan Version) - Videotec EXPT Série Manuel D'instructions

5.5 Limit stops setting (Autopan version)

For installing the pan & tilt unit can be used either the suitable bracket (for wall mounting, to be installed through
4 holes with diameter 11 mm) or the supporting disc of the base body (for pole mounting, provided with 4 holes
with diameter 8.5 mm and located at 90° each other). For allowing the correct rotation of the pan & tilt unit, on
the bottom flange of the central body and on the support disc of the base body, two red marks are shown,
vertically aligned. After having installed the device, these marks should be turned towards the installer, as they
are the installation reference for the correct horizontal rotation of 180°.

The setting of the potentiometers for the electronic limit stops of the automatic cyclic movement is carried out
after having extracted the flange of the base body provided without cable gland, to which it is fixed the printed
circuit board where the two potentiometers RV1 and RV2 are installed. Extracting this flange, and holding as
reference it turned towards the installer, the potentiometer RV1 located on the right side of the printed circuit
board (pan angle) could be used for setting the angle desired for the automatic horizontal rotation, while the
potentiometer RV2 located on the left side of printed circuit board (auto pan position) could be used for setting
the positioning of the angle (previously set through the potentiometer RV1) in the desired zone of the 360°
range, turning it clockwise or counter-clockwise until to obtain the desired positioning. As concerns the
potentiometer RV1, turning it completely counter-clockwise the minimum angle (30°) is set, while turning it
completely clockwise the maximum angle (270°) is set. In order to set intermediate values, it will be necessary
turn it partially clockwise or counter-clockwise until to obtain the desired angles.
For the accessibility to the input control cable connections (soldered), it is instead necessary to extract the
flange of the base body provided with cable gland. From these connections two small coiled cables come out,
which are exploited for interconnecting the control cable to the terminal strip of the central body and to that one
of the camera housing respectively. Being the control cable already connected, it is not necessary to carry out
these connections during the installation, but the accessibility is available only for maintenance service.
