MOTOR FORCE ADJUSTMENT
Adjustment of motor force for the version MT/B4 at 230V~ is by variation of the power supply voltage, for example
using the control unit SERAI CR/41, and by variation of the current control on the version MT/C4 at 24Vdc, for
example using the control unit SERAI CR/39.
In any event, installation must be in full observance with current standards governing power-operated gates;
remember that
the installer is responsible for the system and operation in compliance with
standards.
