3.4.3Setup Alarms

The list of alarms may be reviewed using the UP/DOWN keys. Any alarm may be selected to have it's parameters modified by pressing the ENTER key. All alarms have a time delay and alarm type parameter. The high/low temperature and humidity alarms also have a programmable Trip Point. The Trip Point is the point at which the alarm is activated. By programming a time delay for an alarm, the system will delay the specified amount of time before recognizing the alarm. The alarm condition must be present for the amount of time programmed for that alarm before it will be annun- ciated. If the alarm condition goes away before the time delay has timed out, the alarm will not be rec- ognized. For software alarms such as Loss of Power, Short Cycle, and Low Suction Pressure, a time delay will only delay the annunciation of that alarm. The condition of the alarm is not applicable because the condition has already occurred. For these alarms, the time delay should be left at the fac- tory default of 0.

The following table shows the default time delays for each alarm.

Each individual alarm can be selected as either DISABLED, WARNING, or URGENT. The four cus- tom alarms may also be selected to be a Status Only input. If the alarm is DISABLED, it is ignored. If the alarm is WARNING or URGENT, it will be annunciated audibly, visually, and communicated to a Site Products System if appropriate. When the alarm is selected to be a WARNING, the alarm will NOT activate the common alarm relay. When the alarm is selected to be URGENT, the alarm is first annunciated as a WARNING, and then annunciated again, after the programmed time delay. When the alarm becomes URGENT, the control will activate the common alarm relay. The common alarm relay is de-energized after the alarm has been recognized and when the alarm no longer exists. When the alarm type has been selected to be URGENT, the allowable range for the time delay from warning to urgent is 0 minutes to 999 hours. When any of the four custom alarm inputs have been selected as Status Only, they become digital inputs for monitoring only and are no longer treated as alarms.
