Alarm and Faults

11.4 List of Messages

Table 9

lists available event messages, a definition of the event, and the functions that are activated

with the event by default. The functions are indicated as follows:

— The indicated event initiates the

Auto-Dial

sequence through the optional modem.

— The indicated event activates the

Audible

alarm.

— The indicated event triggers a

Freeze

of the History Log.

— The indicated event

Latches

. A latched alarm remains displayed until the alarm condition

has cleared and the RESET (ALRMRST) button has been pressed.

— By default, all faults and alarms are written to the Event Log. Changing this setting is only

available for the LED units and is set through the RS-232 port. See

Setting Event Masks with

the Terminal on page 83

All of these functions, except Freeze, can be reconfigured to trigger for each event, using the Event

Mask option. See

11.1 - Event Mask

on page 71. The Freeze function is hard-coded and cannot be

changed for a event.
If the front panel of your STS2 contains LEDs and push buttons instead of the touch screen interface,

you can view these messages via the RS-232 port. See

12.1.1 - Connecting and Using a

Terminal

on page 77 for the commands to view the event messages on a PC terminal.

An LED is used to indicate the presence of any active fault or alarm. Refer to

14.0 - Operating the

LED Display STS2

for more information about the LEDs.
