DANGER
Only qualified personnel should conduct the tasks described
in this section of the manual.
The nature of tasks described in this section of the manual requires
individuals to be technically knowledgeable of the associated
dangers. Burns, shock, eye damage, fire and chemical exposure
may occur if this work is not done by qualified personnel. Always
review appropriate Material Safety Data Sheets (MSDS) before

6.1 Scheduled maintenance
Scheduled periodic maintenance requirements of the SS7 sc
Turbidimeter are minimal. Standardization checks and calibration
are the primary requirements. Several other activities should be
performed on a regular basis, but the schedule for these may
depend on the installation and sample.
6.2 Removing a sensor from the system
Prior to physically removing a sensor from the system, record all
user defined settings such as relays, signal averaging, etc. Turn off
power to the sc controller platform and SS7 sc, then disconnect the
sensor at the controller.
6.3 Installing a sensor on the system
To return the system to normal operation following a software
upgrade or sensor repair, perform the following procedure:
1. Detach all sensors from the sc controller platform.
2. From the Main Menu, press the
DOWN key to highlight
TEST/MAINT and confirm.
3. Use the
DOWN key to scroll to SCAN SENSORS and confirm.
4. Remove attached sensors by selecting the corresponding serial
number or select “All”.
5. Power down the sc controller platform, then attach the
sensor(s) to be used.
Note: Clean sensors before installing on the system.
6. Supply power to the sc controller. The system will
initialize automatically.
