1. Brief Overview
SICLOCK GPS1000 is a modern GPS radio-controlled clock which can be used worldwide for the reception of time signals
from the 24 American GPS satellites. At the output of the GPS1000 antenna head a DCF77 time telegram with Greenwich
Meantime is available.
The particular advantage is that the antenna, GPS receiver and GPS decoder are integrated in the antenna head as one
unit and there is therefore no need to lay coaxial cables, nor to separately install the decoder together with power sup-
Both the power supply of the antenna head and also the transmission of the DCF77 time telegram are via loop current by
means of a shielded twin-core control cable with a maximum length of approx. 1000 meters. The power supply module
GPS1000 PS is at the process end of the control cable. The module feeds the loop current connection to the antenna head and
extracts the DCF77 time telegram. For its own supply it has a long range power supply of 24 to 240V AC/DC.
SICLOCK GPS1000 does not require parameter settings.

1.3. Installation Procedure
1. First find a suitable location for the antenna.
When doing this, please take the following into account:
The antenna head should be able to "see" as much sky as possible and must be installed with the housing cover upwards,
parallel to the sky.
The antenna head should NOT be installed in places where there is lightning protection hazard! (see chap. 3)
Make sure that there is easy access for servicing! (Electromagnetic interference fields from the plant do not need to be
taken into account as the operating frequency of GPS1000 is above the industrial interference level.)
2. Mark the drill holes for installing the antenna stand, drill and insert dowels.
3. Make the bore hole for the connecting cable (for wall mounting preferably in the middle underneath the base plate).
4. Assemble the antenna according to figures 9 and 10 respectively.
5. Thread the cable into the bore hole and screw on the stand. For mounting on flat roofs, use additional IP67- distribution
box and additional control cable to extend if necessary.
6. Inside buildings, install the conduit box supplied near to the cable entry (alternatively, install the lightning protection
module 2XV9450-1AR83 and omit the conduit box).
7. Mount the GPS1000 PS near the system to be synchronized (computer, SICLOCK TM, SPC or similar.) (on DIN rails,
19 inch frames or in table housing).
8. Control cable provided on site for GPS1000 PS (terminal X2/11,12) for installation of conduit box for the antenna and
clamp with antenna connection cable (Poling is not important here).
9. Lay the shield of the control cable on the equipotential busbar in the control cabinet.
10. Set up the power supply connection to GPS1000 PS (terminal X1/13,14,15).
11. Setting up synchronization to the plant:
Connection to PC: via cable supplied for X3 at SICLOCK GPS1000 PS to free COM interface.
(Driver software required: 2XV9450-1AR28).
Connection to SICLOCK TM: via shielded twin-core control cable from the terminal X2/1,2 at SICLOCK
GPS1000 PS to SICLOCK TM terminal X2/5,6.
Connection to SICLOCK TS: via shielded twin-core control cable directly from the antenna head (SICLOCK
GPS1000 PS is not necessary) to SICLOCK TS terminal X2/9,10.
Connection to SIMATIC S7 Digital input: via shielded twin-core control cable from terminal X2/1,2 at
SICLOCK GPS1000 PS to the corresponding SIMATIC S7 digital input.
(necessary function module for step7 - software: 2XV9450-1AR30).
12. Switch on the mains power. When the green LED "Pwr" is illuminated, the initializing of the antenna head now begins
(yellow LED "Sig" permanently illuminated). After successful initialization, the initializing of the time reception begins,
which, according to the reception situation and the number of satellites received, can last for up to 30 minutes or longer.
