SICLOCK ® TC100 Operating Instructions
6.4 Connecting alarm and warning outputs
During operation, the SICLOCK TC100 automatically carries out a range of func-
tion tests. If an error occurs, the device generates corresponding messages on
the display. A distinction is made between alarms and warnings.
There is an alarm output and a warning output for external monitoring on terminal
X2.
Figure 6-6 Alarm output X2-7 and warning output X2-8
Example:
Set the alarm output if there is no external synchronization.
Use the Configuration Tool to set the parameter entry /Synchronisation/Exen-
ded/Monitoring/Monitor Synchronization Status (0.09.14) = "Alarm" to activate
monitoring / alarm output in case of error.
