Menu 2 - Lines Menu 2.1 Current consumption of the slave clock lines The current load of the slave clock lines is displayed here in amperes (A). If the master clock has only one or two lines, only one or two values are displayed here. The load capacity depends on the line voltage and the type and number of slave clocks.

If slave clocks with different cycles are operated on 1 slave clock line, select the higher value. Ex- ample: On one line, slave clocks with minute pulse (cycle 12 hours) and digital clocks with 24- hour display (cycle 24 hours) are operated together, in this case select cycle 24 hours.
Menu 2. 7 Activate power reserve - deactivate If the master clock is equipped with power reserve batteries, the power reserve for each line is switched on or off separately here in menu 2.7. The factory setting is "on". For master clocks with at least two slave clock lines, the duration of the power reserve of one line can be increased by deactivating the power reserve of other lines.
The factory setting of 1.0 second of pulse length is optimal for all PEWETA slave clocks. An extension leads to longer reset times. An extension may be necessary under certain circum- stances for special "large clock movements/tower clock movements". A shortening leads to shorter reset times, but can also lead to slave clocks going wrong.
Menu 3 - Switching Menu 3.1 Switching channels Status From left to right (channel 1 to 4), the display shows the current status of the individual switching channels. If the master clock has no or two switching channels, only no or two values are displayed here. Switching channels are a component of the design (see page 8) and cannot be retrofitted.
