3.1. Operator Intervention
Once a formula starts, the machine usually runs automatically. The machine will sound the signal
if an operator needs to make a decision or do something manually. The most common reasons
you'll need to attend to the machine are errors, and to manually add chemicals in some cases.
Error with Operator Signal
3.1.1.
The operator signal will sound and the beacon will flash if an error causes the machine to stop.
These errors usually disable the three-wire circuit, and include a tripped vibration switch or a
malfunction of the inverter that controls the motor.
Figure 16
shows how a vibration switch error
appears on the display.
