The motor operator is protected from overloading by a fuse (F1) under the motor
operator. Only use the same type of fuse that is described on the label close to
the fuse.
If a new command is given before the switch has reached the position of the
previous command, the fuse (F1) may operate.

Impulse control
6.1.1 Impulse control
When using impulse control, the change-over switch is operated by electric impulses. When you
press the control button, the change-over switch is driven to the corresponding position (I, 0, II). The
control impulse must last more than 100ms to take effect. A new command cannot be given until
the change-over switch has reached the position of the previous command. Figure 6.3 shows the
operation of the change-over switch with impulse control.
