*S1 = Continuous operation. The motor can be subject to full load in continuous operation.
*S3 = Intermittent operation. The motor must not be subject to full load for more than 25% of the 10 minute duty cycle.
In practice the motor is not subject to full load for more than one second just as it starts.
**The motor is available both with and without an integrated thermal switch. If the motor has a thermal switch there is a
red label on the motor indicating this.
Gears
Select the opening speed taking account of the size and weight of the gate. The basic rule is to select a lower speed for large
gates.
!
WARNING
Too high an opening speed can result in trapping forces being too
large despite the use of a sensing strip.
