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:
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

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.
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)
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)
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
