SCOM-100, User guide		37
ALH:	Alarm high limit in physical units
	(number in the range of SCL to SCH
	with one optional decimal digit.
	Example: ALH = 121.5)
u:	Physical unit (0-15 characters)
d:	Delay time in seconds (0-65535)

For example let us explain all the different parameter settings to use a 4-20mA, 0-10 bar pressure sensor wired on analog input 2 on the main unit (See section 2.4.2).

The pressure sensor characteristic is shown in the diagram below:

The 4-20mA input signal is converted by the internal A/D converter in the digital raw range of 819 to 4095.
