ALARM BLOCKING

—Prevents nuisance 

alarms when the controller is first powered 
up. The alarm is suppressed until the 
parameter gets to the non-alarm limit or 
band. Alarm blocking affects both alarm 
setpoints. 

DISABLE

—Disables blocking 

AL 1

—Blocks alarm 1 only 

AL 2

—Blocks alarm 2 only 

AL12

—Blocks both alarms 

 ATTENTION 

  When enabled on power up 

or initial enabling via configuration, the alarm 
will not activate unless the parameter being 
monitored has not been in an alarm condition 
for a minimum of one control cycle (167 ms).

AL 2

 

DIAGNOSTIC

—Monitors the Current Output 

and/or Auxiliary Output for an open circuit 
condition. If either of these two outputs falls 
below about 3.5 mA, then an Alarm is 
activated.  This configuration is in addition to 
whatever was selected for AxSxTYPE. 

DISABLE

—Disables Diagnostic Alarm 

ALARM 1

—Alarm 1 is diagnostic alarm 

ALARM 2

—Alarm 2 is diagnostic alarm
