6.6.4.3 Battery Cell Voltage Monitoring
This function is available only on units fitted with software supporting it. The system must
be fitted with Battery Cell Monitor modules.
Entry point to Battery Cell Monitor sub-menu when this
auxiliary is switched On. If it is switched Off the next screen
will be shown and the rest of the menu items will be hidden.

Press ENTER
Displayed when this auxiliary is switched Off.
Displayed when this auxiliary is switched On.
The configuration refers to cell type (2, 4, 6 or 12V) and how
the cells are connected to the monitor - see section 6.11 for
further information.
After pressing ENTER current configuration will flash. Scroll
through available configurations and press ENTER again
once the correct battery type is chosen.
Declare number of battery banks to be monitored. Maximum
is 4.
An alarm is posted if any cell voltage exceeds this value.
Press ENTER and increment or decrement the value as
desired in the normal way.
Similarly a low threshold can be set for the cell voltages. If
during a discharge (or any time) a cell voltage falls below
this value, an alarm is raised.
+dVc is a differential voltage threshold. It is the percentage
voltage by which the voltage of a particular cell exceeds the
average cell voltage for the whole battery.
Low differential cell voltage threshold.
6.6.4.4 Site Monitor
The site monitor is primarily designed to be operated with WinCSU-2 from a PC.
However, once set up the analog signal levels can be viewed and the alarm levels and
scale factors can be modified from the site monitor sub-menu of the MCSU-4.
The site monitor sub-menu is a sub-set of ‘Auxiliary Units’. When Site Monitor is declared
to be Off, no other menu items are displayed.
