For changing the line type, you first have to enter the slave clock lines configuration menu
regardless of the current mode setting. E.g. changing the line type from ”Impulse” to “DCF”:
...
Line
X
[Impulse]
Configuration
Line
type:
Impulse
The modify key
is used for selection of the line type (Impulse/ DCF/ DCF-Imp/
MOBALine).
...
Line
X
[DCF]
Configuration
Line
type:
DCF
Confirm with the navigation key
(OK
).
Caution:
You must not change the line type of a slave clock line when it is connected to
the terminals of the ETC. Make sure that the used slave clocks match your line
configuration settings
before
connecting the line to the terminals.
Notice:
An electronic overload switch protects the output stage in case of short-circuits
on the line.
12.2 Active Line Current Supervision
The model ETC 24(R) provides an active current supervision for its two slave clock lines.
For each line individually a high and a low limit can be entered. The first line of the menu
shows the current value of the line current.
If the measured current exceeds the high limit or if it falls below the low limit an alarm
will occur which indicates a faulty operation on the line. This kind of alarm will not shut
down the line. If the current supervision is not in use, set the high limit to the maximum
(refer to current allocation) and the low limit to zero.
