ProDSS Sensor Installation/Removal
ProDSS cable assemblies that feature user-replaceable sensors include 4 port cables with (626910 and 626911) and
without (626909) a built-in depth sensor. This section pertains to these cable assemblies.
Other ProDSS cable assemblies, like the ProDSS ODO/CT (627150), ProODO (626250) and ProOBOD (626400 and
626401), feature integral (i.e. built-in) sensors. Therefore, sensors on these cable assemblies cannot be replaced by the
user. A complete list of cable options can be found in the Accessories section.
NOTICE: The ProDSS bulkhead and sensor connectors are not wet-mateable. Make sure that the sensor and
bulkhead connectors are clean and dry before sensor installation.
NOTE: Sensor ports on the bulkhead (4 port cables only) are numbered (Figure 4). If multiple sensors of the
same type are installed, the sensor port number will be added to the Run screen display to clarify the
measurement value of each sensor.

Sensor Installation
The ports on the ProDSS bulkhead are universal; therefore, you can install any sensor into any port.
NOTE: A conductivity/temperature sensor (626902) must be installed in a 4 port ProDSS cable for accurate
measurement of all parameters except turbidity and TSS. All sensors, including conductivity/temperature,
must be ordered separately.
1. Remove the port cover shipped with ProDSS cables. This cover fits over the bulkhead to protect the sensor
connectors from contamination and damage during shipment. This cover can be kept for long-term cable
storage.
2. Inspect the bulkhead port for contamination. If the port is dirty or wet, clean it with compressed air.
3. Apply a thin coat of o-ring lubricant to the sensor o-rings. Wipe off excess o-ring grease with a lint-free cloth.
