12.6.20 REL1000: Error Relay Module
The REL1000 error relay module can be switched by various operating states (e.g.: Clock Not Sync). If the
internal hardware clock is running synchronous to the source, the relay is switched to NO (Normaly Open)
mode. In case of an error, the relay switches to NC (Normaly Closed) mode.
Depending on the hardware configuration of the IMS system, i.e. redundant with RSC module and two inte-
grated reference clocks or with SPT module and only one reference clock, different relay states can be switched.
In redundant operation, the two clocks and the changeover unit are monitored as standard (CLK1 - relay
A, CLK2 - relay B, RSC - relay C). This jumper setting is supplied per default in redundant systems.
Possible configurations of Error Output:
Relay A:
Clock 1 / Notification Events
→
Relays
Relay B:
Clock 2 / PPS
Relay C:
RSC / 10 MHz / Notification Events
→
Relay
In redundant mode, the jumpers on the REL1000 are set as shown below:
