1.2 Mode of operation

The main clock 20097 controls and operates analogue (optionally as well digital) secondary clocks by impulses. A highly precise quartz-controlled oscillator with an average accuracy of ± 0,05 s/24 h provides the control pulse for the main clock’s UTC. Or if a GPS receiver is connected its receiver signal provides the control pulse.

When travelling through different time zones, the LT of the main clock has to be adjusted manually. Analogue secondary clocks are readjusted automatically after the preset interval. MOBALine-secondary clocks set themselves automatically after 3-4 s. Digital secondary clocks adopt the modified LT without time delay.

1.3 Accessories

1.1.1 Secondary clocks

We offer a wide range of secondary clocks. Please contact us for a presentation of our assortment.

1.1.2 Extension cards

Depending on the customer’s specification, the following extension cards are included in the delivery or optionally available ( see also "Appendix", section "Extension cards"):

• digital clocks extension card for the operation of digital secondary clocks

• MOBALine extension card for self-adjusting secondary clocks

• analogue clocks extension card for the operation of more than 100 forwards or 50 forwards and backwards running analogue secondary clocks.

• serial extension card for the operation of two different protocols with a differing data frame

1.1.3 Accumulator

The unit is fitted with an accumulator as power reserve. Only when the accumulator is completely discharged, the clock switches itself off automatically.

The following accumulator types are used:

• pbq VRLA accumulator 0.8-12

• Le Long WP0.8-12

• or comparable accumulators with identical performance

NOTICE!

Do only use these accumulator types or comparable accumulators when replacing the accumulator (see also section "Maintenance").

Design and function

1.1.4 Fuses

Main fuse ("MAINS") medium blow 1,0 A (DIN 41571; 5x20 mm)

The main fuse protects the internal processor circuit, the oscillator and the accumulator charge circuit.

In case of a failure of the main fuse, the main clock switches over to the internal accumulator power supply. The display shows the error symbol "E" ( see also "troubleshooting").

Secondary clocks fuse ("SLAVE") medium blow 2,5 A (DIN 41571; 5x20 mm)

The secondary clocks fuse protects the external power supply circuit of the digital secondary clocks, the data outputs of all standard and extension cards as well as the internal interface and the power supply circuit of the display illumination.

In case of a failure of the secondary clocks fuse, the power supply of the secondary clocks is interrupted and they stop running. The display shows the error symbol "E" ( see also "troubleshooting").

5 Installation and putting into operation

1.1 Safety

CAUTION! Electric energy hazard!

The improper installation of the electrically operated main clock may cause injuries or damages of the unit. For that reason:

– The unit shall be installed in accordance with the safety regulations by trained staff

qualified in electrical engineering only!

– Before starting with the installation, make sure it is volt-free and prevent any

1.2 Requirements on the place of installation

possibility of reconnection!

The clock’s construction is shake and shockproof. Nevertheless, the following conditions apply when choosing an installation place:

– no direct sunlight

– ambient temperature: 0-40 °C

– max. relative humidity 0-90 % without condensation

Special care has to be taken for the wall-mounting version:

ATTENTION! Material risk!

The mounting place has to be chosen so that the main clock does not obstruct any motion areas of objects (e.g. doors) or people.

V3.0 01/2011

Page 20

WEMPE digital main clock 20097 Installation and putting into operation

1.6 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. ( 1.4 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 ( 1.4 Fitting of cables). Ensure protection class IP54.

1.7 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 ( 1.4 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 ( 1.4 Fitting of cables). Ensure protection class IP54.

Operation

1.1.3 Synchronisation of the clock with GPS signal

The PPS signal of the GPS receiver is necessary for the exact synchronisation of the main clock.

Additionally, a synchronisation without PPS impulse (NO PPS) can be activated for NMEA receivers.

1. Remove write protection ( 1.1.1).

2. Press key 1 several times until the message on the right appears on the display:

3. Press ENTER key for confirmation. The cursor starts flashing.

4. Press the key 2 to select whether the data is to be adopted with the positive flank (Pos.) or with the negative (Neg.) flank depending on the GPS receiver.

5. Press the ENTER key to confirm the modification. To cancel the modifications, press the MENUE key twice.

6. Press the MENUE key to return to the time display.

NOTICE!

After having finished the settings, the main clock automatically adopts the UTC and date. The LTC has possibly to be set by hand.

NOTICE!

In case the receiver signal is interrupted, the main clock keeps running with a high accuracy thanks to its internal oscillator.

V3.0 01/2011

Page 32

WEMPE digital main clock 20097 Operation

1.1.4 Setting of synchronisation rate

The use of GPS receivers without PPS impulse involves a risk in view of the correct synchronisation of the main clock.

All data frames that correspond to the usual layout are regarded as valid. For GPS receivers with an up-date rate of more than 1 second, this means for example that the receiver transmits the same time for up to 5 seconds and then makes a 5-seconds leap forwards. This results in leaps of the time indicated on the main clock and the secondary clocks and in some cases even a fast adjustment of the secondary clocks is carried out without interfering of the user.

In order to eliminate this source of error, modify the synchronisation rate as follows:

1. Remove write protection ( 1.1.1).

2. Press the key 1 several times until the message on the right appears on the display:

3. Press the ENTER key for confirmation. The cursor starts flashing.

4. Press the key 2 to set whether data is to be synchronised once per second, minute, hour or day.

NOTICE!

During the period in between two synchronisations, the main clock runs with the accuracy of the internal oscillator.

5. Press the ENTER key to confirm the modification. To cancel the modifications, press the MENUE key twice.

6. Press the MENUE key to return to the date display.

NOTICE!

Although a "jumping" main clock display and fast adjustment of the secondary clocks does not occur anymore after having modified the synchronisation rate, it is nevertheless recommended to refit the PPS standard or to let the manufacturer of the GPS system activate at least a higher up-date rate.
