CHAPTER 6: MONITORING
The alarm messages appear only when the alarm threshold has been exceeded for the 
programmed time. When an alarm is assigned to an output relay, the relay can be set to be 
unlatched or latched. When the alarm is set as unlatched, it automatically resets when the 
alarm condition no longer exists. If the alarm is set as latched, a keypad reset or a serial 
port reset is required.
