Connection Of Secondary Clocks; Connection Of Gps Receiver - WEMPE 20097/W Operating Instructions Manual

5.6 Connection of secondary clocks

The standard version of the main clock can control up to 100 forward and up to 50 forward
and backward adjustable secondary clocks. All common secondary clock systems for 12V or
24V impulses can be connected.
The MOBALine secondary clocks are powered with 15V/50Hz AC-voltage by the main clock
via a 2-wire conductor. At the same time the current time is transmitted by means of
amplitudes/frequency modulation. Time adjustments effected on the main clock, are
automatically recognized by the secondary clocks and reproduced.
If several secondary clocks are to be connected, they have to be connected in parallel first
via a power distribution system. The power distribution system is then connected to the main
clock via a supply line.
1. Fit the cables for the secondary clocks supply line. ( 5.4 Fitting of cables)
2. Fix the leads of the secondary clock's supply line to the corresponding terminals (either
to terminals 7 and 9 or terminals 32 and 33, for MOBALine extension additionally
terminals 20 and 44) according to the terminal plan ( annex). Make sure that the
leads are connected firmly to the terminals.
3. Close the electrical connections ( 5.4 Fitting of cables). Ensure protection class IP54.

5.7 Connection of GPS receiver

The main clock can adopt the time signal of a GPS receiver.
All types of GPS receivers supporting the "NMEA 0183 Version 2.0" standard are included in
the basic configuration (for example: MAGNAFOX and LEICA).
Receiver types from other manufacturers can be installed. The description of the output
protocol of the corresponding GPS receiver is needed for this purpose.
1. Fit the cables for the GPS receiver supply line ( 5.4 Fitting of cables)
2. Fix the leads of the GPS receiver supply line according to the terminal plan to the
terminals 15 and 16 as well as to the terminals 40 and 41. Make sure that the leads are
connected firmly to the terminals.
3. Close the electrical connections ( 5.4 Fitting of cables). Ensure protection class IP54.
