General descr pt on

Westerstrand’s KNX analogue slave clock provides the possibility to create a time distribution system with high

accuracy and high reliability through a KNX network.

The clock is intended for connection to a 2-wire bus that combines power supply and KNX communication.

A built-in microprocessor receives time telegram from a KNX master clock, reads the position of the hands, and

sets the clock to the correct time.

Installat on

1. When the clock is wall mounted use the cable inlets, see fig. 1.

2. easure and assemble an appropriate mounting screw (not included).

3. Connect the KNX bus to the black/red connector on the back of the clock.

4. The clock will start to reset itself to 12:00.

5. Configure the clock with the ETS software. The KNX connector, LED and programming buttons are

located on the back of the clock.

6. After the configuration is downloaded, the clock will again reset itself to 12:00, and then wait for a time

telegram. If the parameter “Send Time Request at Startup” has been enabled, the clock will send a time

request to the master clock. This requires that the master clock is configured to receive time requests.

7. As soon as a valid time telegram has been received, the hands will step forward to the correct time.

Descr pt on of Group Objects

ID 1: DateT me

The clock receives time with datapoint type 9.00 and synchronises the local clock accordingly.

ID 2: T me

The clock receives time with datapoint type 0.00 and synchronises the local clock accordingly.

ID 3: Date

Not used in analogue clocks

ID 4: T me Request

To speed up installation, the clock can be set to send a time request at startup. If the master clock

can receive and respond to the request, it will immediately transmit the time. This way the installer

can quickly see if the clock is working or not.

ID5: T meout Alarm

The slave clock will expect time messages with the interval set with the parameter “System Clock

Timeout”. If there are no messages within this time, an alarm can be sent on the KNX bus. If

parameter “Enable Timeout Alarm” is set to “Yes”, the clock will set this group object to ‘ ’. When the

clock again receives time messages, it will reset the alarm by setting the group object to ‘0’.

Descr pt on of Parameters

SCLOMode

SCLOMode is a read only parameter that indicates that the clock is a slave clock.

System Clock T meout

The timeout period is set using the System Clock Heartbeat parameter. The default value is 2

minutes. The timeout value should be set using the following formula:

System Clock Timeout= (System Clock Heartbeat x 2) +

Where System Clock Heartbeat is the transmission interval set in the master clock.

Clock Type

There are two types of slave clocks, the digital that can show both date and time and the analogue

which can only display time. For the analogue clock, select “Analogue”.

T me Format

The clock can receive time in two different formats, datapoint type 0.00 or 9.00 . The default

datapoint type is 9.00 .

Send T me Request at Startup

As default, the slave clock will not send any time requests. To force the slave clock to send a request

at startup, select “Yes”.

Send Alarm at T meout

Select ”Yes” if the clock should send an alarm on the KNX bus at timeout. The default is “No”.

T meout Act on

As default, the timeout action is “Free run”. This means that clock will keep running using the local

clock in the case of a timeout. If “Reset to 2:00”, the clock will instead reset itself to 2:00.

Clean ng the clock exter or

A clean clock is always a more representative product. The exterior should regularly be cleaned to maintain the

clock in good condition.

Cleaning solutions

Never apply cleaning solutions directly to components. Solutions are always sprayed on a cloth, and then the

cloth is used to wipe the component. Almost any type of household cleaner can be used to clean the outside of

the clock case. The cleaner should not dissolve or scratch the finish. When rubbing alcohol is used with cotton

swabs, the swabs should be moist, not dripping with solution. Avoid ammonia-based cleaners.
