Figure 4-37. Remote Contact Inputs
A Alarm Configuration: None, Alarm, or Pre-Alarm.
B Activation Delay: Adjustable from 0 to 300 s in 1 s increments.
C Label Text: An alphanumeric character string with a maximum of 16 characters.
D Contact Recognition: Always or While Engine Running Only.
Remote Analog Inputs
An optional AEM-2020 (Analog Expansion Module) provides eight analog inputs. To make identifying the
analog inputs easier, a user-assigned name
A can be given to each input.
Select the input type B and amount of hysteresis C . The analog inputs are always monitored and their status
is displayed on the appropriate metering screens. A user-adjustable arming delay D allows configuration of
the analog input threshold monitoring in one of two ways. (1) When the arming delay is set to zero,
threshold monitoring is performed all the time, whether the engine is running or not. (2) When the arming
delay is set to a non-zero value, threshold monitoring begins when the arming delay time has expired
after engine startup is complete. When enabled, an out of range alarm
E alerts the user of an open or
damaged analog input wire.
Ranges must be set for the selected input type. Param Min F correlates to Min Input Current G or Min Input
Voltage H and Param Max I correlates to Max Input Current J or Max Input Voltage K .
Each analog input can be independently configured to annunciate an alarm, pre-alarm, or status only L
when the analog input signal falls beyond the threshold M . A user-adjustable activation delay N setting
delays alarm annunciation after the threshold has been exceeded.
The remote analog inputs are incorporated into a BESTlogicPlus programmable logic scheme by
selecting them from the I/O group in BESTlogicPlus. For more details, refer to Section 5, BESTlogicPlus
Programmable Logic.
A remote analog input is disabled when Alarm Configuration is set to “None”. Remote analog input status
is available in BESTlogicPlus Programmable Logic when “Status Only” is selected.
The BESTCOMSPlus Remote Analog Input #1 screen is illustrated in Figure 4-38.
