Connecting Optical Fibers for pH and DO:
ALERT!
Risk of damage to equipment!
Take care not to bend the optical fibers.
The optical fibers for DO and pH readings before (DO1 and pH1, short ones) and after (DO2 and pH2,
long ones) the packed-bed are packed in the crate of the accessories and documentation.
Figure 18: Optical fibers before (short) and after (long) fix bed
Connect the optical fibers after fix bed (long ones) to the optical connectors ‘pH2’ and ‘DO2’ located on
the front of the iCELLis 500+ control system (Figure 19a-b-d). Secure the connector by turning the
metallic part of the connector (Figure 19c). Repeat these steps to connect the optical fibers before fix
bed (short ones) to the optical connectors ‘pH1’ and ‘DO1’ (Figure 19e).
