Above
: Alarm 1 condition triggered when the process variable is greater than the
Alarm Hi Value (Low value ignored).
Below:
Alarm 1 condition triggered when the process variable is less than the
Alarm Low Value (Hi value ignored).
Hi/Low:
Alarm 1 condition triggered when the process variable is less than the
Alarm Low Value or above the Hi Value.
Band:
Alarm 1 condition triggered when the process variable is above or below
the "band" set around Setpoint 1. Band equals Hi Value (Low Value ignored). A
"band" is set around the Setpoint by the instrument only in the "Deviation" Mode.
The Band for the AL 1 would be following the Setpoint 1 value
The Band for the AL 2 would be following the Setpoint 2 value.
The Band or the Deviation Value should be entered under:
AL1 High (if they want Alarm 1)
AL2 High (if they want Alarm 2)
AL Low value is ignored in the Band mode.
Example
: if customer requires a Deviation Value of ±10 degrees around a
setpoint (using Output 2 as alarm)
Output 2: disabled (this enables the Alarm 2)
Alarm 2: - Deviation
Contact Closure type: Deviation---Band
AL2 High: 10 (Band they want around Setpoint 2)
Then the Band Value is to be entered under AL2 HI: 10 not 80+10 = 90
