Continuous Control - ABB OTM C Series Installation And Operating Instructions Manual

6. Operating

6.1.2 Continuous control

When using continuous control, the control command is supplied to the switch continuously. When
you press the control button, the change-over switch is driven to the corresponding position (I, 0, II).
Operation of position 0 will over-run control of the other positions; that is, if you simultaneously give the
0 command with another command, the change-over switch is driven to position 0. Figure 6.4 shows the
operation of the change-over switch 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.
