- Page 2 Vor dem Einschalten Überzeugen Sie sich, ob Ihre Sendung das richtige Gerät Orbit Controls Modell OC 7040A-POL beinhaltet, einschliesslich einer Betriebsanleitung OC 7040A-POL. Vor dem Einschalten des Gerätes überprüfen Sie die Anschlüsse und die Versorgungsspannung. Ein falsch angeschlossenes Gerät kann beschädigt werden und damit auch die mitverbundene Folgeelektronik.

Page 10: Menu Steps
MENU STEPS The text bellow shows the full menu with all options installed. If one or more options are not installed, the corresponding menu Step is suppressed in the menu. The key MENU permits the entry into the menu and scrolling the parameters at the display. The required menu step will be confirmed with ACK. The Cursor (flashing digit) can be moved with ACK and set with UP or DOWN to required value. - Page 11 MENU Aout L Display value for Analogue Output 0 (-10) V and 0/4mA MENU Aout H Display value for Analogue Output 10V and 20mA The outputs 0 or 4mA and 0V or -10V can be selected at the Option Board.

- Page 12 POLYNOM – LINEARIZING The Polynom-Linearizing will be activated in the Menu. A polynom of sixth degree can be used. The Polynom contains 7 coefficients: coef0 cee0 to coef6 coee6, whereas the Index is the Exponent which multiplies the measured value. It will also be multiplied by a tenth power which is entered as coee. The coefficients have 6 digits with decimal point and sign, the exponents can be set from 0 to ±...
