Service personnel can switch off the controller in the "setup"
menu. For details, see

9.4.1 Continuing production after terminating chlorine
During commissioning and in normal operation: Start chlorine
dioxide production:
The undefined content of the reaction tank is flushed into the
batch tank, and the warning message "check ClO2 batch"
appears. The batch should be disposed, see section
9.5.2 Manually draining the batch
After that, the process and dosing proceed in normal operation.
9.4.2 Continuing production after removing a fault
Confirm the alarm message. Continue operation as described in
section
dioxide
9.4.3 Continuing production after changing a chemical
The Oxiperm Pro system automatically continues operation.
9.4.4 Continuing production after a power supply
As soon as the power is restored, the Oxiperm Pro system is
switched on again automatically.
If the reaction tank is full, the liquid is in an undefined state. It can
contain too much hydrochloric acid or too little NaClO
The controller uses the float switch in the reaction tank to
determine whether the reaction tank is empty or full, and

The reaction tank is part-filled or full, the batch tank is empty:
– If the reaction tank is part-filled, it is filled up with water.
The undefined liquid is drained into the batch tank, and the
following alarm message is displayed: "check ClO2 batch".
– Drain the batch tank manually. For details, see section
9.5.2 Manually draining the batch

– The remaining batch is dosed into the batch tank.
– The reaction tank is filled up with water. The undefined liquid
remains in the reaction tank, until the batch tank is empty.
Water is supplied to make the reaction tank overflow, and
the alarm message "check ClO2 batch" is displayed.
– Drain the batch tank manually. If it is not drained manually,
the undefined solution will be dosed.
