1 Installation and assembling
1.1 General Information
MPU-TC is a modular Master Clock and can be configured for industrial application
with up to 6 slave clock lines and up to 32 switching channels, using extension
modules. Specific to the configuration an extension enclosure is required.
The clock can be continuously synchronized using a DCF77 or GPS Antenna.
Daylight Saving Times are calculated automatically based on a user defined entry or
are defined by the DCF77 signal.
The slave clock lines outputs are polarised 24V impulses, the line type can be
defined separately for each line.
The switching channels can switch up to 230V AC signals.
Programming of the switching channels is done in multiple steps.
First the switching times of the switching channels on one day are defined in a
Dayplan. On one day only one Dayplan can be active.
The Dayplans then have to be assigned to a specific date or date period in which
they are active using the Period Assignment menu. Additionally the days of the
week in which they are active can be selected.
The Holidays menu enables the user to assign Dayplans to holidays or holiday
periods which overrule the Period Assignment Dayplan. The standard fixed and
moveable holidays are pre-programmed.

1.2 Installation
The enclosure must be opened cautiously with a slot screwdriver. The screwdriver
has to be pressed against the enclosure snap, when put in the opening hole [1],
while pulling on the top of the enclosure.In the enclosure top there also is a switch
[2], which can be used to disable all switching channels.

1.3 Connections
The MPU-TC can be mounted on a support rail. A position should be considered,
where the cabling fits well through the provided opening (1).
For Wall mounting the provided 8mm dowels and the screw holes (2) should be
used.
If the optional available support rail is used, it must be checked that the enclosure is
correctly snapped onto the rail and afterwards the lock bolts (3) have to be fixed with
screws (4).

1.4 Connection of power supply (230VAC)
The 230VDC mains supply has to be installed by qualified specialists. The wires
must not be energized during installation.
The provided supply cable with ferrite (6) has to be connected to the base circuit
board.
Live wire, neutral wire and protective earth wire need to be attached according to the
labels as follows:
•PE = Protective Earth
•N = Neutral
•L1 = Live
For comfortable mounting the plug can be removed carefully.

1.5 Connection of slave clocks
Slave clock lines are also located on the base cuircuit board inside the housing. The
clocks for line 1 must be attached to the terminal with the label 1.1 1.2 and clocks
for slave clock line 2 should be connected to the terminal 2.1 2.2.
The electrical schema is presented in the following figure.

1.6 Connection of DCF receiver
The DCF77 antenna needs to be plugged into the terminal with the label +DCF-.
Before attaching the antenna the MPU-TC must be taken from main supply, the
polarity of the Mattig-Schauer DCF77 Antenna does not need to be considered.
After powering the MPU-TC again, the signal quality can be checked with the
antenna symbol on the MPU-TC display, the control LED on the base cuircuit board
or the LED on the DCF antenna. All of those indications should blink in a one second
cycle.
If the LEDs blink aperiodic or permanent, then the antenna needs to be positioned
differently. To improve reception conditions please change position of the DCF
antenna as long as necessary. The DCF antenna should be mounted in a 90°angle
to the direction of Mainflingen near Frankfurt/Germany.
In case the signal reception is interfered by means of the shape or material of the
building (reinforced concrete) or due to the surroundings (high buildings, cranes, etc)
the DCF antenna should be mounted externally (facade or roof). The maximum
distance with shielded cable can be 200m.
In other cases the MPU-TC master clock can also be synchronised by GPS antenna
with output of DCF signal.
If the BMC is operated together with the Network Module, it can be synchronized to a
Network Time Server (NTP). In this case antenna input is ignored. For more details
can be found in the user manual of the Network Module.

If a DCF signal is available the switching to DST is done
according to the DST bit in the DCF packet. In case of a
poor DCF signal the DST offset is done according to the
user defined points in time (see chapter Fehler!

DST switching is done only at the user defined points in

DCF
Only the DCF DST bit is used for DST switching.

The master clock does not change to DST.
For the settings DCF and DCF/user the DST announcement bit is analysed.
After identifying 5 successive DCF packets with a set announcement bit within an
hour, a DST switch will happen at the next full hour, even if there is no DCF signal at
that point in time.
If 5 consecutive packets without the announcement bit set are received, there will be
no DST change at the next full hour, when no DCF signal is available at the moment
in time. Even if user defined settings would indicate a change for the setting
DCF/user the switching will not be done.

The next option which is marked with the xin the upper line is used to set the
behaviour in case of a short circuit on the line.
It can be configured after pressing using the button >

As default setting (.) the output of impulses is stopped when a short circuit is
detected and automatically restarted after the short circuit is resolved.
If the √is selected here then the clock checks every second if the short circuit is
resolved and if still is not, after 60 times of checking (60 seconds), the line switches
itself off and has to be re-enabled manually.
The next option determines if the line output follows the Daylight Saving Times. The
default setting (√) lets the line follow the DST settings of the master clock. If .is
selected the line will not switch to summer time, but will keep the standard time
always.

3.2.4 Line Impulse/Pause Duration
Display: 24 Pulse Pause 01

This menu enables the user to set the duration of the impulses on the line. The first
parameter 1s means that the impulse for the clock will have a period of 1 second.
The second 1s indicates that after the impulse there will be a minimum 1 second
pause until the next impulse is generated. For a minute impulse clock it will take 2
seconds to make up one minute if the salve clock is not already synchronised.
The line will be pre-programmed to 1s pulse duration and 1s pause duration.
For standard applications the value should be 1s 1s, for special applications the
duration of the minute pulses/pauses can vary between 1s, 2s, 5s and 10s. The
pulses/pauses for second impulse slave clocks may vary between .05s, .10s, .20s
