7. Setting of Ø nom. value potentiometer
• Voltage values U
Da
and U
Di
measured at random
potentiometer setting.
• Nom. voltage U
Danominal
is calculated.
U
Danominal
= nominal voltage outer diameter
D
a
= outer diameter
D
i
= inner diameter
U
Da
= voltage outer diameter
U
Di
= voltage inner diameter
Q
= diameter ratio
∆
U
= voltage difference
• Set U
Da nominal
by potentiometer.
8. Set max. roller Ø.
9. Push “set” key.
10. Release “set” key.
Reference Ø is accepted,
“Ø contr.” lights up.
11. The installation is ready for operation.
NOTE
Should the installation not function properly, consult
“4. Identification and causes of failure / corrective action”
