Alarm Logging . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . The log will consist of which output became active, which parameters
caused the alarm to become active (useful for the AND type alarm)
along with the date and time that the alarm became active. This log is
cleared whenever any of the output alarms are cleared. Can be
activated or deactivated by the user.
Output Contact Closure Functions
Duration . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0 to 255 minutes (user selectable). Determines how long the alarm
output should stay active once it is triggered. Default = 10 minutes
Reactivation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0 to 255 minutes (user selectable). Determines how long to leave the
alarm output deactivated once it is deactivated. Default = 0.
Pulse Width . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0 to 9999 milliseconds (user selectable). Default = 2000 milliseconds
(2 seconds).
Activation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Continuous or Pulse (1-time) (user selectable). Determines whether a
pulse for alarm activation is continuous throughout the activation time
or a one time pulse. Pulsed relay oriented devices will require the one-
time pulse. Default = Continuous
Circuit Behavior . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Normally Open or Normally Closed (user-selectable). Determines
whether the circuit stays open or closed when no alarms are active. The
opposite behavior occurs for an active alarm condition. Normally closed
is the most typical operation for Irrigation controller use. Default =
Normally Closed.
