5.1.1 Impulse control

When using impulse control, the switch-disconnector is controlled by electric impulses.
When you press the control button, the switch-disconnector is driven to the corresponding
position (I or 0). The control impulse must last more than 100 ms to take effect. A new
command cannot be given until the switch-disconnector has reached the position of
the previous command. Figure 5.3 shows the operation of the switch-disconnector with
impulse control.
If a new command is given before the switch has reached the position of the
previous command, the fuse (F1) may operate.

5.1.2 Continuous control

When using continuous control, the control command is supplied to the switch
continuously. When you press the control button, the switch-disconnector is driven to the
corresponding position (I or 0). The position will change only when the new command is
given. Figure 5.4 shows the operation of the switch-disconnector with continuous control.
The continuous control command can be given with push buttons, cam switches or
with relays incorporated in PLC equipment or with other suitable contacts.
