Notes
1.
The minimum figures shown are for battery voltage greater than the minimum
Standby (Battery Fail) level i.e. 21.5V. The figures shown in brackets are for a
battery voltage greater than 22.5V.
2.
Modes 1 & 2 have the same thresholds before the Alarm state is latched. For Mode
2 additional current is turned on once the Alarm state is latched (refer to Graph
3.4.2).

Notes
3.
I.e. short at end of an 800 Ohm circuit (gives voltage band B2 alarm, ref graph 3.4.1).
4.
I.e. short at end of a 2000 ohm circuit (gives voltage band B3 alarm, ref graph 3.4.1).
MCP Zener Diode
For voltage band B3 operation
