History Freezes

When certain system failures occur, service personnel may request a system history freeze

(system data snapshot), so they can analyze system activity for the time period preceding the

alarm.

Freezing or Unfreezing the System History

You can freeze or unfreeze the current node system history.

To freeze or unfreeze system history:

1. Dial 9900 (9100 in Europe) to turn on diagnostics mode. DIAGNOSTICS ON appears.

2. Dial 9993 (9193 in Europe) to freeze the system history, or dial 9998 (9198 in Europe) to

unfreeze the system history. HISTORY FROZEN (or UNFROZEN) appears. If you try to

change the state of the system history to its current status, HISTORY ALREADY

FROZEN (or UNFROZEN) appears.

3. Dial 9900 (9100 in Europe) to turn off diagnostics mode. DIAGNOSTICS OFF appears.

Freezing or Unfreezing the Network History

You can freeze or unfreeze the network history for any node in the network. Service personnel

can then pull the information from each node for troubleshooting purposes. Nodes are assigned

to freeze zones by the database programmer to allow selective freezes. You must know which

zone to freeze or unfreeze.

A node can be in more than one freeze zone. If you freeze a zone that contains a node that is

already frozen, SOME NODES ALREADY FROZEN appears and the node remains frozen. If

you unfreeze a zone with unfrozen nodes in it, SOME NODES ALREADY UNFROZEN appears.

To determine the individual freeze status of the nodes, check the Message Print output.

To freeze or unfreeze network history:

1. Dial 9900 (9100 in Europe) to turn on diagnostics mode. DIAGNOSTICS ON appears.

2. Dial 9939 (9139 in Europe) to freeze the history a network node, or dial 9989 (9189 in

Europe) to unfreeze the history of a network node. SELECT FRZ ZONE (0–9) #

appears.

3. Enter the number of the node you want to freeze or unfreeze. FREEZE ZONE XX IS

FROZEN (or UNFROZEN) appears. If you try to change the state of the system history

to its current status, FREEZE ZONE XX ALREADY FROZEN (or UNFROZEN) appears.

4. Dial 9900 (9100 in Europe) to turn off diagnostics mode. DIAGNOSTICS OFF appears.

NOTE Do not perform these procedures unless directed to do so by service personnel.
