6.2 Single String Display
The Single String Display lists all jars associated with a string. Each string can be given its own
name which is displayed near the top of the page.
This page will display up to 40 jars. For each jar present in the string the jar voltage and
admittance change is displayed. The admittance change field will indicate “undefined” until the
initial cell admittance has been set in the Jar Setup Display.
The button text on this
page is color coded to
indicate the jar status.

Cell button to view the
detailed information on
the jar.
The Discharge Status
indicator displays the
present state to this
string either “Normal”
or Discharging”. The
discharge event is

count of the Discharge

also displayed. The event counter and total time are stored in nonvolatile memory and can be
reset from SNMP or by deleting the string. Alarms may be provisioned for the Discharge Status

All Conductance measurements and Equalization are automatically disabled on all strings when a
discharge event is detected on any string.
