SWT 3000 Alarms

Alarm output via the ALRS or ALR module

In the SWT 3000 system alarms are distributed with the relay contacts of the ALRS resp. ALR
module. An alarm is active, when the relay is de-energized.
The following alarms are distributed:
When the alarms appear they are immediately written into the event recorder even if the output
via the alarm relays is delayed!
The module is identical with the ALRS from the system SWT 2000 F6 however in the system
SWT 2000 F6 the 3 alarm relays are designated with GENALR (General alarm), SALR (Transmitter
alarm) and EALR (Receiver alarm).

In the system iSWT 30000 (integrated in the PowerLink ) the alarms are distributed via the ALRS
module which is controlled from the CSP module. The alarms from the iSWT 3000 are transmitted
cyclically via LAN to the CSP.

Alarms on the CLE

On the CLE module (only with the analog line interface LIA in the SWT 3000) the following alarm
LED are existing:
Table 60:
LED Reason(s)
SAL (red) SAL_CLE: Output level to low (alarm from internal measuring point)
EAL (red) EAL_CLE: Receive level alarm (PAL) or limit of the command output time (COx) ex-
ceeded
S/N (red) S/N: Signal-to-noise alarm
The alarm output depends as well on the configuration of the device (primary and secondary path,
no secondary path, LIA and LID, only LID resp. only LIA) as shown in the examples below.
