Sound Alarm When…Menu-continued
When this menu item is set to YES for each humidity sensor, the controller alarms if the humidity sensor fails.
The alarm requires the humidity sensor to give 10 invalid readings during a single hour to avoid false alarms. The
humidity sensors are checked every 15 seconds, so a complete failure would cause an active alarm state in as little
as 150 seconds. All invalid readings are recorded in the Alarm History. If more than one humidity sensor is installed,
press the PLUS and MINUS keys to scroll through the list of humidity sensors to set each alarm.
This alarm setting is especially useful if you rely on the humidity sensor to trigger humidity-based purges or to enable
and disable evaporative cooling devices.
SOUND ALARM WHEN.... Z1-S01
Humidity Sensor #1 Reading is Bad: YES
ACTIVE ALARM FOR 11/8 AT 9:20 ZONE 1
#01 Temp Range: #03 61.7 #02 75.2 CNT 12
The alarm system should be tested periodically to ensure proper operation.
Setting this menu item will activate the alarm relay, with a "Temp Range" alarm, if the difference of the temperature
readings of any two temperature sensors is greater than the value you set. The alarm will display the two sensors
that caused the alarm, and the readings of those two sensors at the time the alarm activated. This alarm can no
-
tify you when the temperature changes drastically from one end of the barn to the other. It also can indicate when
a temperature sensor is going bad and starts sending lower or higher readings than it should. When the alarm is
active, the controller continues to use the readings from the temperature sensors to control devices. To prevent
nuisance alarms when the temperature only changes momentarily, as when a door is opened and closed, the alarm
will not activate until it has taken ten readings that were off by the set value. The "Range Alarm" is not self-clearing,
so the alarm could activate within a few minutes (10 continuous out-of-range readings) or a few hours/days/months
(intermittent out-of-range readings). Press
DOWN
arrow key to set this alarm.
If the alarm is active, as show below, you should determine why the readings between the two temperature
sensors were so far apart before clearing the alarm.
