High Alarm Outputs

Low Alarm Outputs

The Alarm Outputs dialog box is used to assign the 4 outputs of the alarm to recorder relays. The relays themselves have the address programmed in the Main Editing Window under Recorder Setup - Alarm Relays or by adding a station using Recorder Quick Setup.

If a relay has not been assigned an address, it will show "Relay X - No Address Assigned".

To enable the output, "Enable Output" must be set on the High or Low alarm category for the alarm we are setting up as well as the "Enable" setting for the Relay in this window, See image below. This is set by default when any of the alarm relays have the "Enable" checkbox checked in this dialog box. (New for Version 5).

Relays A, B, C, D can be used to turn on up to 4 relays on 4 different outstations when the alarm occurs.

Relay Settings

• Enable
  To Enable the Relay, the "Enable" checkbox should be turned on.

• Latch
  To Latch the alarm on, the "Latch" checkbox should be turned on. When an alarm output is latched, it must be manually cleared via the Alarm Status dialog box in the recorder before its output is reset.
  If the Latch setting is not on, the Alarm is considered a control output and the output is reset when the reading clears the differential limits for the line. Latched alarms appear in the Alarm Status dialog box and appear as Red on the data screen. Unlatched alarms do not appear in the Alarm Status dialog box and appear as Blue on the data screen.

• Pulse Output
  The Pulse Output setting is used to turn the relay on momentarily when the alarm occurs. If this is set, the latch means that the alarm will appear in the Alarm Status dialog box for viewing and clearing, and the alarm is still considered valid until the user manually clears it.

The relay settings are error checked. If you enable a relay, and its relay shows "No Address Assigned", a message box will appear as follows.

This message is new for Version 5.

Enable Output is shown ticked, which allows the Recorder to write the relay states when the alarm occurs.
