5.6 S4 ELEMENTS
The 745 has the ability to monitor any external quantity, such as bus voltage, battery voltage, etc., via a gen-
eral purpose auxiliary current input called the analog input. Any one of the standard transducer output ranges
0-1 mA, 0-5 mA, 4-20 mA, or 0-20 mA can be connected to the analog input terminals. The analog input is con-
figured in S2 SYSTEM SETUP / ANALOG INPUT and the actual values displayed in A2 METERING / ANALOG INPUT.
This section contains the settings to configure the analog input monitoring elements. Included are two analog
input levels, each with a programmable pickup threshold and time delay.

Range: Disabled / Enabled
Range: Self-reset / Latched / None
Select None to inhibit the display of the target message when the element
operates. Thus an element whose "target type" is None will never disable the
LED self-test feature because can not generate a displayable target
message.
Range: 1 to 65000 (steps of 1)
Enter the analog input value (in the units programmed) above which the
analog input level 1 element will pickup and start the delay timer.
Range: 0 to 60000 (steps of 1)
Enter the time that the analog input value must remain above the pickup
level before the element operates.
