2 2/7 TECHNICAL SPECIFICATIONS Crystal frequency: MHz Accuracy: 0.1 s/24 hours (20ΕC) Microprocessor: HD6303Y Eprom: Type 27C512 with label ANVA-Dvvv, vvv=version Output: Minute impulse: 24 V reversing 1/1 min, 2 seconds, max load 1 A. World time output: 24 V push/pull max load 0.5 A, simplex 2-wire, 1024 bits/second, format: 8 data-bits, 1 stop-bit. Impulse memory: Program memory: 72 hours (impulse memory with rapid impulsing after power failure) 10 years (lithium battery). Mains voltage tolerance: +/- 10% Max ripple (DC-models): 0.7V RMS Ambient temperature: 0Ε to +40ΕC Dimensions: Accessories: Width x Height x Depth = 265 x 217 x 135 mm Radio synchronizing DCF77, Rugby (MSF), FM, RDS, GPS, 1/1 minute, 2 minute. INSTALLATION The World Time Master Clock is intended for fitting on a wall. 1. Screw in the upper fixing screw halfway and hang up the unit. 2. Screw in the two lower screws, accessible inside the plastic cover. 3. Connect the digital clocks according to the connection drawing. PROGRAMMING - WHEN INSTALLING When the Master Clock is connected for the first time the following question is displayed: Accept using [YES]. Set, by using the arrows, correct UTC-time, year, month, day and hour, but some minute ahead of present time. Wait for correct time and synchronize using [YES]. Set UTC-time? :00? The World Time Master Clock is now in running mode. Digital slave clocks will start displaying time as soon as UTC-time is set. In a system with analogous slave clocks, each clock must be programmed individually by function Group. Mon 3 Sep 12:07:49 CET:14.07 Lon:13:07 CST:07:07 Mos:16:07 GMT:12.07 EST:08:48

3 3/7 PROGRAMMING Programming is carried out with the six buttons [ ], [ ], [ ], [ ], [NO] and [YES]. Data is shown on a 4x20 character display. Programming is self-instructive and to simplify the dialogue Yes/No questions are used. By pressing [ ] several times the program always will enter running mode. In running mode the display shows: The first line shows current UTC-time. The other lines show current time of the world time slave clocks. If more than 6 places are defined, these places are displayed by pressing [ ] and [ ] from running mode. After total reset of the master clock all slave clocks are stopped. A function is chosen in this way: 1. Make sure the program is in running mode by pressing [ ]. 2. Press [ ] until desired function text is displayed. 3. Accept this function by pressing [YES]. 4. Carry out programming. 5. After programming the function text is displayed again. 6. Go back to running mode by pressing [ ]. These functions are defined: Mon 3 Sep 12:07:49 CET:14.07 Lon:13:07 CST:07:07 Mos:16:07 GMT:12.07 EST:08:48 Set UTC-time Group Spec.-functions Alarm Set universal time. Program rules for separate slave clocks. Special functions. Alarm functions. Function Set UTC-time Make sure the clock is in running mode. Press [ ] until the display shows: Press [YES] Answer [YES]. The display shows year, month, day, hour and minute: Enter UTC time! The flashing value is changed with buttons [ ] and [ ]. Move to other positions with buttons [ ] and [ ]. Synchronization takes place when [YES] is pressed. Go back to running mode by pressing [ ]. Set UTC-time Set UTC-time? :00? Set UTC-time Digital slave clocks will start displaying time as soon as UTC-time is set. In a system with analogous slave clocks, each clock must be programmed individually by function Group.

4 4/7 Function Group Remark: Group no. 1 must always be used for Local Time. Group 1 London This function defines time rules for the analogous slave clocks. Each group has default values according to the dipswitch configuration. Normally no programming, except field >ON/OFF= is required. The other fields only must be programmed if an other time-zone is desired or the rules for summer-time are changed. With this function these default values are overwritten. After reset all groups are stopped (OFF). OFF Fields for programming are emphasized. UTC +0.0h 14:14 (14:14) Sun S= W= First group number is selected. The digit on line 1 is flashing. Press [ ] and [ ] until desired group is displayed. Press [YES]. If the group is started (=ON), the display shows: Accept by pressing [YES]. Go to desired field with buttons [ ] and [ ]. Change value with buttons [ ] and [ ]. During prog. This group is stopped. Continue No/Yes Explanations: Field London Field UTC+0.0h Field 14:14 (14:14) Field Sun Choose a place from the table on page 6. Alternative >Undefined= is also allowed. Then nothing is displayed in running mode for this group. Offset in hours to universal time according to the table on page 6. Enter current slave clock time. This field is only visible for analogues clocks! Don=t change the hands of the slave clock manually. The clock tries to correct to the time shown in parenthesis. Weekday for summer- and winter-time change. Value No SW is also possible. This means no summertime for this slave clock. Fields S= W= If a weekday was entered in the previous filed this field tells first possible dates for summer/winter-time. See the table on page 6. The hour is current local hour. Function Alarm Display and remove alarms. An existing alarm is indicated by lamp ALARM on the front. After start-up of the master clock alarm Reset is set. The display than shows: Restore the alarm by pressing [YES]. Restore Reset If Master Central 2 does not receive synchronization impulses within 12 hours alarm No Radio is set. Go back to running mode by pressing [ ] [ ]

5 5/7 Function Spec.-functions Special functions are functions which are not so often used. These special functions are defined: Language RS232 Signal Radio alarm Impulse length Choose language. RS232 parameter setting. Acoustic alarm signal ON or OFF. Set alarm time for radio clock Impulse length to slave clocks 1. Make sure the program is in running mode by pressing [ ]. 2. Press [ ] until the display shows: 3. Press [YES] 4. Press [NO] until desired special function text is displayed. 5. Select this special function by pressing [YES]. 6. Go back to running mode by pressing [ ] [ ]. Spec.-functions Special function Language These languages are defined: English (default), Svenska (Swedish), Suomi (Finnish) and Deutsch (German). Press [NO] until desired language is displayed. Accept with [YES]. Special function RS232 Not used Special function Signal Switch ON or OFF the internal alarm buzzer. If ON is chosen a signal sounds after alarm time-out. Press [ ] and [ ] until desired status is displayed. Accept with [YES]. Press [ ] [ ] in order to enter running mode. Signal OFF? Special function Radio alarm This function has no meaning if no radio is connected for time synchronization. Set alarm time-out in hours. At time-out lamp ALARM is switched on. Output relay ALARM is closed (output 5 is closed to output 6). In mode Man a radio-alarm always must be restored manually. In mode Auto a radio-alarm is removed automatically when the radio is accepted again. Radio alarm Time: 712 min 12h Restore Man? S Töreboda, Sweden Internet:

6 6/7 Special function Impulse length Set impulse length to slave clocks. This function assumes a system with analogous clocks. Default length is 2.0 seconds. S Töreboda, Sweden Internet:
