Tab. 47 SIGMA CONTROL 2 ready states
When the operating voltage is applied to the SIGMA CONTROL 2 controller, the operating control
is in OFF mode.
If all faults are inactive, pressing «ON» produces the ON ready mode.
If remote control is active, the remote load demand and remote idle demand signals are evaluated.
When the remote control is deactivated, the system switches to Local mode. The load signal is
generated by the «ON» key or the two-point controller.
Pressing the «OFF» key produces the SWITCH OFF ready mode. The machine is shut down un‐
der control. The sound enclosure's fan will run on to prevent a heating up of the interior caused by
pent up heat. If «ON» is pressed during the control shut-down process, the ready control returns to
ON mode.
You can interrupt the controlled machine shut-down by pressing «OFF» a second time. The ready
control changes to OFF ready mode. The sound enclosure's fan stops.
5.8.1.1 Ready control without remote acknowledgement
If the ready control is in ON or SWITCH OFF ready mode and a fault occurs, the ready control
switches to OFF ready mode.
If the Remote acknowledgement function is inactive, the machine cannot be operated until the fault
is corrected. When all fault causes have been corrected and all faults have been acknowledged,
you must again press «ON».
5.8.1.2 Ready control with remote acknowledgement
If the ready control is in ON ready mode and a fault occurs or is active, the ready control switches
to ON/FAULT ready mode but not OFF ready mode. In the ON/FAULT ready mode, the machine
behaves similar to the OFF ready mode.
When all fault causes have been corrected and all faults are acknowledged, the ready control re‐
turns to ON ready mode and the drive motor starts. You don't need to press «ON» a second time.
If the ready control is in ON/FAULT ready mode, you must expect at any time that a remote
acknowledgement may switch the machine to ON ready mode and the drive motor is started.
5.8.2 Operating control
The operating control mode specifies whether individual machines or machines under master con‐
trol are activated. It evaluates the Load run command and Idle run command signals.
