Operation Level Section 7-3
7-3-9 Alarm Upper Limit Value 2 (al2h)
Alarm Lower Limit Alarm Value 2 (al2l)
Condition: Alarm 2 type must be set to upper and lower limits, upper and
lower limit range, or upper and lower limit alarm with standby sequence.
These parameters independently set the upper and lower limit alarm values
when the mode for setting the upper and lower limits is selected for alarm 2
type.
Function • These parameters set the upper and lower limits of alarm 2.
• The decimal point position is dependent on the currently selected sensor.
For analog input, it is dependent on the “decimal point position” setting.
