Figure 53: Various possible battery status screens
The PLC battery is used for memory back up and retention. If the battery is removed while the PLC is
not powered, the PLC will lose its internal memory and the PLC program. The same thing will occur if
the PLC battery goes dead. The battery also controls the various clocking functions of the PLC
program, and the program may start to work unreliably if the battery is low due to clock skew.
Consult Appendix B on replacing the PLC battery in order to find the correct replacement part and to
dispose of the old battery.
The HMI battery is used for the internal clock on the HMI, and it is not used for backup or retention
of the HMI program. Removing the battery will not result in a loss of program. If the battery dies, the
internal clock on the HMI will be affected and there may be some strange results. Please consult
Appendix A and Appendix B on how to replace the HMI and PLC battery respectively.
III. Bearing Greasing Interval
The bearings on the Gravity Separator need to be greased at regular intervals. The suggested
number of hours is 2000. Once the machine has been run for 2000 hours, it will issue a warning,
changing the Bearing Greasing Interval status from a green button with “good” indicated on it to a
red button with “regrease” indicated on it. The number of hours since the last bearing greasing is in
the blue box. The number of hours can be reset at any point to 0, when hopefully the bearings have
been greased. See Figure 54.
