31.17 The 4-20ma SPARK MAP configuration setting enables or disables the ability to
remotely control the spark number via the auxiliary 4-20mA input. When turned
on, the valid 4-20mA range is limited to 2-22mA, so even when this feature
turned on, the assertion of a spark number based on the 4-20mA signal will
only be active if the 4-20mA signal is within the limit range of 2-22mA. If the
current is outside of the range, a warning is asserted.

4-20mA Current Loop to Spark Map
• Current > 2mA and <6mA: Spark #1
• Current >= 6mA and <8mA: Spark #2
• Current >= 8mA and <10mA: Spark #3
• Current >= 10mA and <12mA: Spark #4
• Current >= 12mA and <14mA: Spark #5
• Current >= 14mA and <16mA: Spark #6
• Current >= 16mA and <18mA: Spark #7
• Current >= 18mA and <22mA: Spark #8
Any values outside of those listed will produce
a diagnostic warning and the current loop will
have no effect on the spark number.
