2.2.3 Status Optical Coupler
The status optical coupler provides a potential isolated switching contact for monitoring the
modules synchronization status.
Function:
Status output via 3-pole terminal with selection of the desired synchronisation status at which
reporting is to be activated:
Optical coupler:
•
Selected status or better achieved
– Optical coupler switched through
•
Selected status not achieved
– Optical coupler blocked
The desired reporting status is set via the
hmc
software.
2.2.4 Serial-Remote Interface for
hmc
software
The connection to a PC’s RS232 serial interface is made by means of the KA6870 interface
cable supplied.
The Serial-Remote interface for the configuration of the module is located on its front panel.
The transmission line (Tx) and reception line (Rx) have status LEDs which signal the activity
on the respective interface line.
No further configuration of this Serial-Remote interface is necessary.
2.3
Back-up Clock
The module has a maintenance-free, buffered backup clock for at least three days.
After a power failure the clock starts with the internal back-up clock information unless valid
time information was available beforehand.
2.4
Voltage Feed
The voltage feed takes place via the integrated power supply in the device.
2.5
Further Signal Outputs
Further available signal outputs of the respective system are stated in the accompanying
manual of the specific-device.
