CLOCK SETUP
After the clock has been powered down for longer than 2 weeks the time keeping system may have to be preset to the current
time and date again.
NOTE:
If a 10 Year Lithium Battery Backup option is installed, the clock will preserve the correct timekeeping for up to appx.
10 year period.
Such battery should be replaced at least once every 10 years, even if no power down occurred.
If a Battery-Less option is installed, each power down period may last up to at least 14 days. It will recharge itself
automatically within several minutes when the power is restored.
INITIATING REMOTE CONTROL operation
NOTE that the Remote Control may have been locked-out by enabling the function Fn62 or Fn63.
Irrespective of any previous settings, the clock will always accept the Remote Control commands for a period of
appx. 33 seconds following each power up and this period is extended by further 33 seconds whenever a valid key on
the remote is activated.
During that initial period the functions Fn62 and/or Fn63 may be disabled to cancel the Remote Control lock-out.
Always, before using the Remote Control, remember to press the CLK key to set the remote to the clock mode.
If the Remote Control is Enabled and the power has been present for longer than appx. 33 seconds, press the
MUTE key 5 times within appx. 4 seconds period to initiate the clock PROGRAMMING mode. This mode time-out is
extended by further 33 sec. each time a valid key is pressed. If that timer expires, the MUTE button has to be activated again 5
times (within appx. 4 seconds) to restart the programming mode.
TIME / DATE SETUP
After the power-up, the clock may display the text: “SEt” if the internal backup ran “out of charge” or the clock was not
previously set. If however the time is still correct, the clock will resume the normal operation.
NOTE, that it is advisable that the display be set to indicate the Real Time clock ( not the timer or temperature or other data )
before the time / date programming is initiated. This may be easily achieved by pressing the SCAN key on the remote until the
clock time comes on the display. If non of the functions Fn 2 to Fn 6 are enabled, initiate the clock time programming mode as
described previously and press the FUN key to jump to any of the time or date screens, and then continue programming of the
clock time / date as described below.
After initiating the clock PROGRAMMING mode as described previously, perform the following:
1.
Press the NXT key to initiate the Clock Time Preset Mode and with UP and DN keys set the time minutes and hours.
2.
Using the FUN key scroll to the display screen with month and year, and with UP and DN keys set the current data.
3.
Using the FUN key scroll to the display screen with date and month, and with UP and DN keys set the current date.
4.
Using the FUN key scroll to the display screen with day-of-week and with UP and DN keys set the current day.
5.
Wait for several seconds without pressing any keys. The clock will resume normal operation.
NOTE: During programming use the “NXT” key to move the cursor when needed.
NOTE, that the clock Seconds will RESET to 00 when the “CLR” key is pressed during the real
time clock programming.
DISPLAY MODE SETUP
Several Clock Display screens can be enabled/disabled by enabling/disabling the corresponding Functions: Fn 0 to Fn 7.
Initiate the Function Preset Mode ( See the “LIST OF FUNCTIONS” section ) by following the steps listed in the “FUNCTION
SETUP Procedure”.
When more than one display mode is enabled, the clock will display these screens in an ALTERNATING fashion.
For example: if Fn 3, Fn 2 and Fn 1 are enabled, the display will start with HOURS:MINUTES display followed by
13
KERA TECHNOLOGIES INC. 2013
www.ledclocks.com
SELENA Multifunctional LED Clock
USER MANUAL V32D
MONTH:YEAR display, followed by EXTERNAL TEMPERATURE display and all over again: HOURS:MINUTES display
followed by ... etc...etc...
NOTE, that the Real Time Clock mode (Fn 3), when alternating with other displays, always persists on the display the longest
(appx. 10 sec) while other displays will each remain on for shorter periods (appx 5 sec). This persistence split may be altered
by enabling the functions Fn 40 and / or Fn 41 .
If only one display mode is enabled, it will remain on the display all the time.
All three Time display Formats are available in all SELENA clocks.
The Function Fn 8 can be used to select between the 12 and 24 hour format.
To select the Military Time format, enable the function Fn 45.
To select the display of AM or PM text indicator in the 6-digit clock, or in the Text display,
enable the functions Fn 8 and Fn 85.
HALTING the ALTERNATING DISPLAY in the Digital Time section
The user may (ON DEMAND) HALT the alternating display by pressing the HOLD key at any time. The screen currently on
the display will remain active until either a programming mode is initiated or the SCAN key is pressed.
Similarly, whenever the Timer/Counter START, STOP or RESET is performed externally or via the remote, the display will
switch to the timer/counter mode. Press the SCAN key to return to other display screens.
To scroll quickly through the enabled screens, press the SCAN key repeatedly.
NOTE: when the function Fn 62 is enabled, ALL COMMUNICATION with the clock via the remote control is DISABLED.
To regain the remote control access disconnect the power momentarily, then restore it and disable Fn 62 within 33 seconds.
Also see the function Fn 63 to disable the remote communication except the timer functions and the brightness control .
DATE / TEXT and ZONE Text display

USER MANUAL V32D
CYCLING ( LOOPING ) UP/DOWN STOPWATCH TIMER ( automatic Reset and Restart )
This function may be used either with the remote control or when the external inputs for Start, Stop, Reset are installed (see
Fn 36 ).
By enabling the function Fn 28, the timer may be set to the LOOPING mode of operation. In this mode, once STARTed, the
timer/stopwatch will continue counting down ( or UP if the function Fn 87 is also enabled ), until it reaches 00:00 in the countdown mode or the PRESET value in the count-up mode. At this point it will reset itself to the starting value and continue
counting. This process can be interrupted at any time by activating the STOP or SET ( RESET ) key ( or external input ).
NOTE, that in this mode the internal buzzer and/or relay CAN also be controlled by the timer. See the functions Fn 17, 37, 49.
At each “expiry” of the timer, the internal buzzer ( Fn17 ) and/or the internal relay ( Fn 37 ) may be enabled to become active
for a short period ( 3 to 5 seconds when Fn 49 is also enabled ) or until the MUTE or the SET key is pressed on the remote
( or until the external RESET input is activated ).
Please note, that when the remote control is used to operate the timer or when Fn 58 is enabled and the external START/
STOP/RESET inputs are used, the timer can be “HALTed” at any point and then restarted.
UP / DOWN TIMER RECOVERY after Power Failure
( Optional Feature )
When the function Fn 43 is Enabled, the Up/Down timer can recover the lost time and continue counting as if the power was
present all the time.
When the function Fn 42 is also Enabled, the lost time will not be taken into account and the timer will restart in the HALT
mode after the power returns. To continue counting, press the STRT key on the remote ( or activate the external START
input ).
This option may not be available on standard clock models unless specifically ordered.
1/100 SECOND RESOLUTION for UP TIMER/STOPWATCH
( Optional Feature )
Enable the function Fn 35.
Note, that this option may be used either in 4-digit or in 6 digit displays, however to show Sec:1/100 sec in the 4-digit display
the function Fn 38 must also be enabled.
NOTE : , The 1/100 stopwatch can be operated via the remote control when the function Fn 36 and Fn 59 are also enabled.
However, the 1/100 sec timer function should be used when the external inputs for Start, Stop, Reset are installed ( and Fn 36
enabled ), since the speed of reaction to the STRT or STOP key on the remote is not determined and may not be predictable
in the 1/100 sec resolution.
AUTO-RESTART for UP TIMER / STOPWATCH
( Optional Feature )
This function may be used only when the external inputs for Start, Stop, Reset are installed ( Optional Feature ).
Enable the functions Fn 36 and Fn 57.
NOTE: The 1/100 second resolution mode may also be activated by enabling the function Fn 35 .
In the Auto-restart mode, the timer will start counting UP when the START input is activated and will automatically STOP and
RESTART each time the START input is reactivated. At each RESTART, the display will show the “most recent count”
between the two starts. Activating the STOP input will stop the timer permanently until the START input is activated again.
The Auto-restart mode can be used to “measure” the time periods between periodically occurring events ( the START input
activations ).
SWITCHING THE DISPLAY BETWEEN THE TIMER AND THE REAL TIME CLOCK
1) If using the remote to control the timer:
After finished using the timer, press the "SCAN" key on the remote.
The clock will go to the real time clock display mode or any other mode set ny any of the functions Fn 0 to Fn 6.
If the timer is to be used again, press any of the SET, STRT, or STOP keys.
NOTE, that if the SCAN key is pressed while the timer is still running and the real time clock is displayed, the DOT in the lower
18
KERA TECHNOLOGIES INC. 2013

SELENA Multifunctional LED Clock
USER MANUAL V32D
right corner of the display will be flashing to indicate that the timer is running in the background. To see the timer then, press
the STRT key ( or SET or STOP key ) on the remote.
2) If using the external Start/Stop/Reset inputs for the timer:
After finished using the timer, press the "SCAN" key on the remote or activate the external RESET input and hold it for 5
seconds. In both cases the display will go back to the real time clock display mode.
OTHER possible MODES:
Depending upon the desired operation, the clock may be set to alternate between the timer and the real time clock display,
even if the timer is not presently running.
To do that, enable the function Fn 7 and have the function Fn 3 also enabled ( default ).
Generally, the first 8 functions ( Fn 0 to Fn 7 ) control what the display will show in the alternating mode. The timer display
screen is Fn 7.
However, the timer display can be initiated at any time even if Fn 7 is not enabled, as described above, by pressing any of the
timer keys on the remote or activating any of the timer external inputs ( Start/Stop/Reset ).
If the display is set to alternate, pressing the HOLD key at any time, will stop the alternating mode.
To resume the alternating press the SCAN key.
This way, even if several screens are alternating, like: time, timer, date, temperatures ( if installed ), Julian day ( if installed ), it
is possible to FREEZE the particular screen by pressing the HOLD key while the desired screen is on the display.
EXTERNAL START / STOP / RESET INPUTS
FOR UP / DOWN TIMER / STOPWATCH and EVENT COUNTER
( Optional Feature )
The SELENA timers and event counters may be set up to use external inputs for Start, Stop (count UP, count DOWN) and
Reset. These inputs are available via the screw terminal block accessible at the back panel ( if installed ).
To activate the External Inputs for the Up/Down Timer/Stopwatch or Event Counter, enable the function Fn 36.
CAUTION: External inputs may be connected to DRY CONTACTS ONLY. Any voltage carrying signals connected to those
inputs may cause irreversible damage. However, in special applications it is possible to apply a voltage within the range from
0 to +5V between the Common (0V) and any of the external control inputs if an external current limiting resistor is also used.
NOTE:
If the function Fn 59 is also enabled, the timer may be operated via the remote concurrently with the external inputs.

TYPICAL WIRING OF EXTERNAL DRY CONTACT SWITCHES FOR STANDARD TIMER/COUNTER OPERATION
The Timer activated via the external inputs behaves in a similar fashion as when it is operated using the Remote Control unit.
However, note the following:
1.
The Timer or Counter initial count may be preset only via the remote control (by pressing the SET key).
2.
A) If the Function Fn 58 is NOT ENABLED, activating the START input will start the timer only if it was previously
RESET either by activating the external RESET input, or via the remote control, by pressing the SET or CLR key.

B) If the Function Fn 58 is ENABLED, activating the START input will start or restart the timer only if the STOP
(HALT) input is NOT activated.
In the Event Counter mode (Fn 31), activating the UP input will increment the count by 1.
3.
A) If the Function Fn 58 is NOT ENABLED, activating the STOP input will stop the timer and it may only be
restarted from the beginning after activating the RESET input or pressing the SET or CLR key on the remote.
B) If the Function Fn 58 is ENABLED, activating the STOP (HALT) input will “halt” the timer.
C) If the Function Fn 58 is ENABLED, and the START input is permanently activated, then the STOP (HALT)
external input may be used as the “DISABLE” for the timer for as long as this input remains activated.
In the Event Counter mode (Fn 31), activating the DN input will decrement the count by 1.
NOTE: If the internal buzzer is enabled (Fn 17) it will be activated whenever the count reaches 0000 while counting
down. The MUTE key or the SET key on the remote, or the external RESET input may also be used to silence the
buzzer ( or reset the internal relay ).
4.
If the Function Fn 7 is not set as the exclusive display screen mode, pressing the STRT, STOP or SET key on the
remote will bring the Timer display on screen. Similarly, activating the external RESET input will have the same
effect.
5.
When the External Inputs are enabled (by enabling the function Fn 36), only the SET key on the remote may
activate the timer or counter preset. The STRT and STOP keys on the remote are not operational in this mode
unless the function Fn 59 is also enabled, in which case the CLR key may also be used to reset the timer.
6.
When the External Inputs are enabled (by enabling the function Fn 36) and the function Fn 68 is also enabled, the
external START can START/RESET and can also STOP the timer. The external STOP and RESET inputs do not
have to be used.
7.
When the External Inputs are enabled (by enabling the function Fn 36) and the function Fn 69 is also enabled, the
external START can START/STOP the timer. The external STOP input does not have to be used. The external
RESET input still has to be used to RESET the timer.
PROGRAMMABLE MULTI-EVENT TIMER
( Optional Feature )
The Programmable multi-event timer modes allow for presetting of the time instances (hours and minutes of the day for each
day of the week) at which the internal buzzer and/or internal relay(s) may be activated in order to control the operation of some
external devices and/or sounding an Alarm.
The duration of each event is also individually programmable. There may be up to 32 events per day and each day of the
week may be programmed with a different schedule.
The programmable multi-event timer is selected by enabling the function Fn 48.
Each event time occurrence and event duration period (alarm period) may be programmed. In addition, each event can be
marked to perform an OPTIONAL activation of a COUNT-UP or COUNT-DOWN timer that will run and display until the next
event.
All programmed data is stored in the internal, permanent memory which is retained even without the supply power.
Up to two optional, internal relays may be ordered with most clock models. They are designated as Relay 1 and Relay 2.
In most applications only Relay 1 is needed in order to control an external load like for instance a siren / buzzer or a light.
During the programming of each event, the “duration time” may be set from 0 up to 58 seconds, or until the next event. During
that period the internal Relay 1 will also be energized if the function Fn 37 is enabled.
The Relay 2, if installed, may be controlled by programming the “ option number “ ( OP zz ) for each event.
In most models, both the Relay 1 and 2 have SPDT contacts accessible at the terminal block on the back panel of the clock.
The standard switching capabilities of these contacts are 10Amp, 250V max.
HOW TO PROGRAM THE MULTI-EVENT TIMER
Programming of the Multi-Event Timer is performed using either the wireless IR Remote Control included with all clocks or the
optional, wired Remote Control unit.
The Multi-Event Timer may be programmed at any time during the regular clock operation and DOES NOT require invoking of
the Clock Programming Mode.

1.
Press the SET key at any time during the normal clock operation.
The display will show the Weekday and the Event number for that day.
2.
The Event number will flash rapidly to indicate that it is active for selection. Use the UP and DN keys to select the
event number for that day.
3.
To move the cursor to the Weekdays press the NXT key.
Use the UP and DN keys to select the day and press the NXT key. The display will show: du:xx (or: dxxx) where
“xx” (or “xxx”) is the Alarm duration period in seconds ( 0 to 58 ) for the event being programmed.
NOTE that when the duration is set to 59 seconds, the Relay 1 (if enabled by function Fn37) and / or the internal
buzzer (if enabled by function Fn17) , will remain energized until the next occurring, valid event with the duration
programmed as different than 59 seconds.
4.
Using the UP and DN keys, set the required Alarm duration period in seconds. When satisfied, press the NXT key.
5.
The display will show the hour and the minute (HH:MM) of the event that day. Using the UP and DN keys preset the
required time of the event. To move the cursor press the NXT key.
6.
The display will show: OP zz , where “zz” is an additional option that can be activated at the time of the event. This
option allows to cause the display to show a running UP or DOWN timer that is automatically programmed with a
time period equal to the time difference between the CURRENT and the NEXT valid event . Depending upon the
selected option number, the event may cause the internal Relay 2 ( if installed ) to be activated as well. In such case
the Relay 2 will remain energized until the next valid event. The Relay 2 contacts are accessible at the back panel of
the clock.
7.
NOTE that in the 4 digit clocks the timer Count-Up or Count-Down format may be in Hrs:Min or Min:Sec depending
upon the setting of the function Fn 38. Also, if the Hrs:Min format is selected, the timer display will switch
automatically to Min:Sec whenever the current timer reading is under 1 hour,
Using the UP and DN keys select the required option for the event. The available options are as follows:
Option “00” = sets this entire event as NOT VALID ( this event will be skipped by the timer routine ).
Option “01” = no options to perform.
Option “02” = activate the count DOWN timer automatically to count DOWN the time until the next event
and DO NOT energize internal Relay 2.
Option “03” = activate the count UP timer automatically to count UP the time until the next event
and DO NOT energize internal Relay 2.
Option “04” = activate the count DOWN timer automatically to count DOWN the time until the next event
and ENERGIZE internal Relay 2.
Option “05” = activate the count UP timer automatically to count UP the time until the next event
and ENERGIZE internal Relay 2.
Option “06” = ENERGIZE internal Relay 2 only, no timer to run.
7.
When satisfied with the preset data, press the HOLD key to store the data in memory.
MAKE SURE that this is done WHILE either the duration, the options or the Alarm Hours:Minutes is on the
display. If it is not done so, the OLD data shall be restored in the program memory.
8.
The display will flash the text: “Strd“ momentarily to indicate that the Alarm data has been stored in memory.
9.
Press the NXT key to go back to Step 2 in order to continue programming of other Events
or
Wait a few seconds for the system to return to the Normal Operating Mode. The Event Timer schedule will begin
executing automatically.
Remember, that in order to assure the correct operation of the programmable timer, the real
Date and Time of the clock has to be set correctly.
NOTE that the order in which the clock is searching for active alarms is from event “00“ thru event “31“. The search is
performed at 00 seconds of each minute of the real time. The First encountered active alarm shall be executed and further
search shall be aborted until the next minute of the real time clock reading. Therefore, if more than one event for the day is
identical with any other, only the younger (in order) event number shall be executed. This may have application in deactivating
any unused alarm events by setting them as identical to the highest used event number for the day. However, it is a good
practice to deactivate the unused events by setting their option number to 00 (OP 00 ) .
Note, that if certain events show unrecognizable characters and / or show the event hour:minute as 55:55 , these events will
be ignored by the program anyway and therefore do not need to be deactivated manually.
To be able to control the Internal Relay 1 operation during the Timer Alarm periods, enable the function Fn 37 (see
FUNCTION SETUP Procedure section).

one of the following methods of communication:
1.
Power Line Carrier System with Synchronizing signal carried by the Power Line that is also supplying the power
for the clock. A dedicated Master transmitter must “inject” the sync signal into the power line.
2.
Similar as the Power Line Carrier Sync protocol only the Sync signal may be either a dedicated wire with High
Voltage ( usually same as the line voltage ) or a Low Voltage (5V to 35V AC/DC) signal.

See the following sections for the description of each of the above sync systems.
POWER LINE CARRIER Synchronizing signal ( Fn 23 enabled )
( Optional Feature )
Large System Clock installations may be synchronized by injecting a strong, low frequency signal into the power line at certain
times of the day. The Slave Clocks receive that signal and self-adjust their internal circuitry in order to remain “IN-SYNC” with
the Master clock and all other clocks in the system.
Two distinctive types of sync signals are sent with a different purpose:
1.
12 HOUR Sync Mode ( disable Fn 14 )
Sent from 57th minute 54th second to 58th minute 02 seconds of every hour except at 05:57.54 and 17:57.54 when
the signal lasts until 58th minute 08 seconds.
2.
24 HOUR Sync Mode ( enable Fn 14 )
Sent from 57th minute 54th second to 58th minute 02 seconds of every hour except at 05:57.54 when the signal
lasts until 58th minute 08 seconds.
Each clock may be setup to respond to ANY SELECTED sync signal frequency within the range of the clock model.
Normally this range will be from 2,000 Hz up to 16,000 Hz.
To select a particular Sync Frequency perform the following:
1.
Make sure that functions Fn23, Fn 31, 38, 39 and Fn 11 are Enabled.
2.
Press the “SET” key on the Remote and select the frequency in multiples of 10x by pressing the “UP” and “DN” keys.
For instance to setup 2925 Hz select the number: 292 .

USER MANUAL V32D
After the frequency selection has been made, the functions Fn 31 and Fn 11 may be disabled or left enabled.
IMPORTANT: The Sync signal Frequency programming affects the current Stopwatch/Timer/Counter memory.
Therefore, if timers or counters are also being used, DISABLE the function Fn11 and renew the programmed
starting time / count after finishing the zone offset programming. If the timer, not the counter is to be used,
also disable the function Fn31.
NOTE1: It is possible to monitor the presence of the Sync signal detected by the Slave Clock by enabling the function
Fn12. When Fn12 is enabled, the colon in the time clock display will flash when the sync signal is present.
NOTE2: In systems with the WIRED Impulse Sync transmitted through a separate Cable, High Voltage or Low Voltage, the
operation is similar except the SIGNAL Frequency selection is NOT NECESSARY and the function Fn 13 must be
also enabled. The sync signal should then be connected to a pair of designated terminals on the back panel of the
clock.
MASTER—SLAVE Sync System with Serial Communication
( Optional Feature )
Large System Clock installations may be synchronized by linking them together in a serial communication network using a
“Twisted Pair“ 2-conductor cable, power line serial communication, Ethernet/Internet or RF ( radio ) communication.
Slave Clocks receive the data transmitted by the Master Clock ( SELENA or other ) or a PC and interpret that data to
synchronize themselves with the Master.
In the simplest system the basic configurations for the Master-Slave operation are as follows:
1.
SLAVE for TIME SYNC only
( for all protocols )
The slaves will interpret the Time data from the Master and will set its own internal clock “in sync” with it.
In these configurations, even if the data connection is lost, the Slaves will continue accurate timekeeping based on
the latest, successful sync data reception.
A.
B.
2.
To use the standard SELENA Time Sync communication protocol enable the appropriate functions as
listed in the Configuration Table below.
To use the ASCII Time Code Format “0,1,2 or 3” or Lathem protocol enable both Fn 34 and Fn 46 and
select the sync format by enabling Fn11 and Fn12 as required.
SLAVE as the DISPLAY REPEATER form the MASTER clock screen ( This option is allowed only when the
SELENA Time Sync protocol is used ). See the function Fn 33.
The Slave will repeat all the display data as transmitted by the Master.
In this configuration the Slave will not be able to perform any other display functions except when it is put in the
programming mode via the Remote Control. In case of a loss of communication, the slave display may “freeze” at
the last received screen.
The function Fn33 may be used in Special Applications as the Master display contents repeater for broadcasting to the slaves.
This may work ONLY with the SELENA Time Sync protocol.
When other communication protocols are enabled, the clock may automatically DISABLE the Fn 33 Display Repeater Mode.
3.
EXTRA DATA TRANSMISSION from the MASTER or from designated Slaves
( This option is allowed only when the SELENA Time Sync protocol is used ).
See the functions Fn 81, 82, 83.
The Master ( or a PC ) or in some cases the selected Slaves or Repeater slaves, may be setup to transmit special
data with selected parameters or commands. For instance the temperature measurement results, the relay control
or the timer setup data may be sent from the Master or the repeater to some slaves that are setup to receive such
data.
Appropriate control software ( and hardware ) and functions must be installed and enabled to use this configuration.

2-WIRE MASTER – SLAVE SYSTEM INSTALLATION ( RS485 or RS232 )
( Optional Feature )
A twisted pair, 2 conductor cable must be connected “IN PARALLEL” to all clocks in the system. Additional clocks may be
added at any time and/or taken away from the system either by Selecting/Deselecting the appropriate Sync Control functions
or physically.
Normally, up to 64 clocks (or optionally up to 400 clocks) can operate within a single communication network wiring without
any additional signal boosting. It is advisable that for each 64 slaves at least one Opto-Repeater be used to amplify the
signal. Such repeater is an Option # 841 in the SELENA systems and is installed inside the clock that is purchased with that
option. Alternately, a third party RS485 or RS232, or other standard signal booster/repeater may be used to improve the
signal quality or strength.
Clocks that are not enabled as slaves may continue to operate in the Stand Alone mode.
For the SELENA Sync Standard Protocol:
To keep the Slave clocks synchronized with the Master, setup the appropriate function as listed in the Clock
Configuration Table or use the sync repeater configuration.
See the Sync Repeater function description in this manual.
MASTER – SLAVE SYSTEM INSTALLATION with PC as the MASTER
( Optional Feature )
A PC may be used as the MASTER for the entire clock system.
SELENA clocks do not have to be synchronized all the time. A sync signal every several hours may be sufficient to keep all
clocks working within one second accuracy. Also, when the power is interrupted and later restored, SELENA clocks will
continue to count the time accurately thanks to the internal battery-less (or optional Lithium battery ) backup.
All communication methods are possible to be used in a configuration with the PC as the Master as follows:
1)
The PC may send the sync to an External Power Line Modem ( with RS232, RS485 or USB input ) that sends the
signal to the slaves through the power line wiring. In this case the slaves have to have the Power Line Modem
receiver option installed.
2)
The PC Master may send the sync to the first Slave that has a compatible RS232, RS485 or USB input and then
that slave will broadcast the sync signal into the power line wiring through its internal Power Line Modem. In this
case the slaves have to have the Power Line Modem receiver option installed.
3)
The PC may send the sync to an External RF Modem ( with RS232, RS485 or USB input ) that sends the signal to
the slaves through radio. In this case the slaves have to have the RF Modem receiver option installed.
4)
The PC Master may send the sync to the first Slave that has a compatible RS232, RS485 or USB input and then
that slave will broadcast the sync signal through radio with its internal RF Modem. In this case the slaves have to
have the RF Modem receiver option installed.
36
KERA TECHNOLOGIES INC. 2013
www.ledclocks.com
SELENA Multifunctional LED Clock
USER MANUAL V32D
The Master PC may broadcast the sync signal directly into the slave network or it may send the sync to the First Slave that
is setup as the Sync Repeater clock which will then broadcast the signal to other slaves and / or repeaters.
Consult the particular communication protocol since not all are allowed to use the sync repeater functions.
For the SELENA Sync Standard Protocol:
The software driver package “PCT2Kera.exe” must be installed on the Master PC to allow it to send the internal PC
clock data as the Master Synchronization signal to all slave clocks. The software works in background (if properly
installed) and has several features that may be customized by the user.
In order to have the whole system synchronized with, for example, the Atomic Clock time or a GPS Atomic Time, another
widely available software package may be installed on the same PC that will allow for updating of the internal PC clock
through the internet, a special WWVB ( or other Time Broadcasting radio stations ) receiver card, a GPS or a network, or
manually.
MASTER – SLAVE SYNC SIGNAL RANGE EXTENDER – REPEATER configuration
using SYNC REPEATER function Fn 53
( Optional Feature )
In some installations the sync signal may become deteriorated due to the long distance of wiring or weakening of the RF signal
in RF communication etc... In such cases SELENA clocks can be setup to extend the signal range by repeating the Master
sync signal at different “Time Slots” than the original Master transmission.
The repeater function, when enabled, will cause the selected clock(s) to retransmit the sync signal at various times
( channels ) during each minute. NOT ALL slaves should be set up with this function enabled. Only a few slaves should have
this configuration at locations where the sync signal becomes too weak for the slaves farther down the sync path.
The “Repeater” slaves must have the functions Fn 34 and Fn 53 enabled and the appropriate Repeater Channel selected.
All other slaves in the system must have either the function Fn 34 enabled only to receive the sync on ALL CHANNELS or the
function Fn 53 enabled only to receive the sync on the Selected Channels only.
NOTE, that irregardless of the settings, ALL SLAVES ALWAYS “listen” to the sync signal on the 05th second of each
minute.

combination of functions Fn 88 and Fn 89 in all slaves, repeaters and the Master.
NOTE 2: In the Master – Slave system with the Sync Range Extenders-Repeaters the Master MUST NOT transmit all the
time or at the channels that the repeaters use themselves for retransmission.

To use the SELENA clock as the Master in the ASCII Time Code Format “0 or 3” enable both Fn 32 and Fn 46
and select the required Format with Functions Fn 11, Fn 12 and Fn 13.
Note, that only the Format 0 or 3 may be selected in the Master.
NOTE: ONLY ONE MASTER IS ALLOWED TO OPERATE ON THE SAME NETWORK OR A COLLISION WILL OCCUR.
A Twisted Pair cable must be connected “IN PARALLEL” to all clocks in the system. Additional clocks may be added at any
time and/or taken away from the system either by Selecting/Deselecting the appropriate Sync Control functions or physically.
Clocks that are not enabled as slaves may continue to operate as stand alone.
Normally, up to 64 clocks can operate within a single RS485 communication network wiring without additional signal boosting.
It is advisable that for each 64 slaves one Opto-Repeater be used to amplify the signal. Such repeater is an Option #841 in
SELENA systems and is normally installed inside the clock that is purchased with that option, or a third party signal booster
may be installed.
MINUTE IMPULSE Sync System
for 2-wire, 3-wire and Reverse Polarity 1 Minute and 1/2 Minute Impulse
( Optional Feature )
The MINUTE IMPULSE Synchronization slave mode may be activated by enabling the Function Fn 47.
ONLY 2 WIRES, Line A is used by the SELENA clocks to achieve successful synchronization.
SELENA clocks will respond to the Minute Pulses within the range of + 5 to + 35 VDC presented at the appropriate external
inputs.
The current load requirement on Line A inputs are very low and are equivalent to an Input Resistance of 4.7 to 10 Kohm per
input.
The functions Fn 11 and Fn 12 select the specific protocol for the Minute Pulse sync as follows:

Additional Special sync Feature:
Independent of the Fn 11 and Fn 12 settings, the functions Fn 23 and Fn 13 may also be enabled. This will cause the Selena
clock to respond to a Positive Sync signal presented on a separate low or high voltage input. The protocol will be similar as in
the Power Line Carrier Sync mode ( see Power Line Carrier sync description ), except that a Positive DC Signal or an AC
signal ( 50/60Hz ) is used rather than a specific Frequency. This may allow the user to independently sync all Selena clocks in
the network to the closest hour (58th minute) and/or to 5:58 if the function Fn 14 is enabled and also to 17:58 if Fn 14 is not
enabled.
NOTE, that the above feature is optional and requires that the appropriate signal inputs be installed on the clock back
panel. Specify the required features when ordering.
BCD Time Code synchronization Slave / Receiver ( SIMPLEX compatible )
( Optional Feature )
The BCD Time Code Synchronization slave mode may be activated by enabling the Function Fn 21.
SELENA clocks will respond to the signal within the range of + 5 to + 35 VDC presented at the appropriate inputs.
The current load requirements are very low and are equivalent to an Input Resistance of 4.7 to 10 Kohm.
The input is electrically isolated from all internal electronics via high isolation opto-coupler that can withstand high voltage
differences of over 1,500V.
This Sync option can receive BCD Time Code at either 50Hz or 60Hz clock speed and it detects the correct clock
automatically.
MULTI-ZONE Clock Systems
( Optional Feature )
The SELENA Multi-Zone clock ( V25 and later ) configurations are based on the ability of the clocks to be synchronized to
the Second only or the Minute-Units only or to an absolute time hours and minutes Offset.
All methods allow the zones to differ by as little as 1 minute from each other.
The internal timekeeping by each zone clock allows it to display the zone time and the zone date as well.
In clocks with the TEXT display, the ZONE names as well as the zone dates may be stored and displayed electronically and
they may be made to alternate between several different screens per each zone ( see Fn 64, 65, 66, 80, 85, 86 ).
The ZONE Master clock and each of the ZONE Slave clocks in the Multi-zone configuration should be setup separately with
the zone time and date or the zone offset. Each zone can be setup to any time and/or date.
In practice, the Master is usually set to the GMT ( or UTC ) or the Local time / date.
An external Master clock may be used to synchronize the entire system with, for instance, the Atomic clock time or the
building network time. This external Master may be a PC or any other Master clock that has a compatible serial data output.
NOTE:
To prevent unauthorized access to the clock programming, the function Fn 62 may be enabled, ALL
COMMUNICATION with the clock via the remote control is then DISABLED. To regain the remote control access
remove the power momentarily and disable Fn 62 within the first 33 seconds
Similarly, the function Fn 63 can me used to Partly Disable the access via the remote control. Here, only a limited
timer and dimming operation will be allowed.
NOTE that the above functions may be also used when setting up the time zones to prevent the master or other
zones from being altered accidently while operating the remote control. Usually however, one clock at a time only
should be powered up when redefinig the zone clocks settings or, when several multi-zone clocks are housed in the
same enclosure, a dedicated switch on the side of the enclosure will alllow to select the zone that is to communicate
with the remote control.
There are two possible configurations that may be used in the Multi-Zone system:
NOTE:
The DEDICATED MULTI-ZONE NETWORK with the Seconds SYNC FUNCTION Enabled ( Fn 50, Fn 51 )
Option # 741 has been discontinued in Firmware Versions 25 and higher.
Type “A”
MULTI-ZONE NETWORK with ABSOLUTE ZONE OFFSET ( Fn 50 )
This configuration requires at least one of the following wired or wire-less serial communication
options installed:
# 725, 725RF, 725ETH, 725NTP, 725GPS, 725232, 724RS.
41
KERA TECHNOLOGIES INC. 2013
www.ledclocks.com
SELENA Multifunctional LED Clock
USER MANUAL V32D
This configuration may be used either when the individual zone clocks are installed in separate enclosures or when a
group of zone clocks is installed in a common enclosure.
One of the zone clocks ( in the group ), that has the required options installed, may be designated as the Master.
Alternately, an external Master or a PC with installed Master-Slave driver software may be used.
All other zone slaves must have a serial sync signal inputs installed and have the slave function ( mostly Fn34 )
enabled.
The sync signal may be transmitted by the master at any time and at any intervals. The slave zones time offsets can be
set to differ even by as little as 1 minute from the master time.
Once in the Programming Mode, the multi-zone ( Fn 50 ) function and the Zone Slave function ( Fn 34 ) should be
enabled and the ZONE OFFSET should be initially programmed manually in all zone slaves.
TO SET THE ZONES OFFSETS
1.
2.
3.
Use the switch on the side of the enclosure to select the zone ( if multi-zone system in a common enclosure ).
Initiate the functions programming mode ( see the manual ).
Make sure that the zone is set as SLAVE ( Fn34 enabled and , if required, set the appropriate combination of
functions Fn53,54 and 55 ).
4. Make sure that the zone has Fn50 enabled.
5. Enable Fn38, Fn39 and Fn51 ( offset preset enable ) and wait till the display returns to showing the clock time.
6. Press the "SET" key on the remote and using the UP and DN keys, preset the "time offset hours and minutes" for
the zone. Use the "NXT" key to move the cursor.
NOTE, that setting the hours to less than 24 makes the zone offset negative and to over 24 hours sets a positive offset.
The minutes are set as an absolute offset.
For instance: if the hours:minutes are set to 21:30 then the zone offset = [ Master - (2hrs:30min) ].
Setting the hours:minutes to 27:30 makes the zone offset = [ Master + (3hrs:30min) ].
7. Press the “SCAN” key to return the display to the clock mode.
8. Initiate the functions programming mode again and Disable Fn51 ( zone offset programming enable ).
IMPORTANT: The TYPE “A” Zone Offset programming affects the current Stopwatch/Timer/Counter memory.
Therefore, if timers or counters are also being used, renew the programmed timer starting time or the
counter count after finishing the zone offset programming.
Type “B”
STANDARD SYNCHRONIZED NETWORK with x5th MINUTE-UNITS and SECONDS SYNC
FUNCTION ENABLED ( Fn 90, 91 ) .
This configuration can be used with any of the wired or wireless options series # 725 or 724RS installed.
This configuration requires that the slaves have the serial communication functions enabled, in most
cases the function Fn34. The sync RANGE REPEATER functions Fn53, 54 and 55 may also be used.
When a number of clocks is synchronized using the SELENA Time Sync protocol, or in some instances also other
protocols, it is possible to set the slave clocks to synchronize either “only to the Second” ( enable the function Fn
90 ), or to the “x5th Minute-Units and the Seconds” ( enable the function Fn 91 ), rather than the entire time data.
In this configuration, some or all slave clocks should be initially set manually to different time and date, for instance
different Zones.
1.
2.
3.
4.
5.
Use the switch on the side of the enclosure to select the zone ( if multi-zone system in a common enclosure ).
Initiate the functions programming mode ( see the manual ).
Make sure that the zone is set as SLAVE ( Fn34 enabled and , if required, set the appropriate combination of
functions Fn53,54 and 55 ).
Make sure that the zone has Fn91 or Fn90 or both functions enabled.
Set the clock time to the current time for the zone ( see the manual ) and wait till the display returns to showing the
clock time.
After the first minute of operation the slaves and the master seconds will fall in sync. The minutes may sync within the
first 10 minutes of operation.
Remember that in order to make the Master synchronize the zone slave clocks for the first time, it is a good practice to
set the slaves ( zones ) seconds as close as possible to the master seconds.

4)
The SELENA Time Sync protocol, and in some instances also other protocols, MAY NOT ALLOW the slave to sync
to the master signal from the 50th second of the previous till the 5th second of the next minute.
When Fn 91 is enabled ( x5th Minute-Units sync ), the slave will sync on the 5th minute of each 10-minute period
only ( i.e. 05th, 15th, 25th, 35th, 45th and 55th minute). The hours and the minute tens will not be affected.
When Fn 90 is enabled ( sync the seconds only ), this method will cause the zone to sync ONLY the SECONDS of
each minute. The hours and minutes of the zone time will not be affected.
The SELENA Time Sync protocol, and in some instances also other protocols, are usually allowed to sync the
slaves ONLY on the 5th second of each 10-second period except the 55th second ( i.e. 05th, 15th, 25th, 35th, and
45th second).
NOTE: It may be a good practice to enable both Fn 90 and Fn 91 in the slaves to make sure that the slaves receive the
sync more often than just once every 10 minutes.
IMPORTANT:
If the particular zone requires that the zone minutes are not multiples of the Master 5-minute periods, the function Fn 91
SHOULD NOT BE ENABLED. Only the function Fn 90 should be activated thus allowing the slave to sync to the
SECONDS ONLY, and all minutes and hours should be initially set manually to within 1 minute of the real zone time.
Note, that in this configuration the sync RANGE REPEATER functions Fn53, 54 and 55 may also be used if necessary.
IMPORTANT: The TYPE “B” MULTI-ZONE configuration allows the slave zones to remain correctly offset from the
Master Time as long as either the supply power is present or the internal backup remains charged.
TEMPERATURE MONITORING and CONTROL with ALARM
( Optional Feature )
In all temperature monitoring or control configurations the function Fn 61 must be enabled.
The functions Fn 0 and Fn 1, when enabled, will cause the display to show the temperature sensed by one or two probes.
Up to 2 temperature probes may be connected to the clock terminals ( optional ).
For the ease of understanding, the probes are designated as Internal and External, even though they may be both wired
externally.
The clock is capable of monitoring and controlling ( optional ) the temperature sensed by the external and/or internal probe
(use function Fn 27 to select the controlling probe) . The wired sensor probe(s) can be located at a significant distance away,
up to 500 feet ( 150 meters ) or, optionally, one probe may be installed on the side of the clock enclosure.
The system also stores the historical Minimum and Maximum Temperature readings that can be displayed ON DEMAND
via the remote control ( by pressing the UP or DN key ).
In addition, by presetting the LOW and HIGH TEMPERATURE ALARMS, the user may activate the control operation of the
Internal Control Relay ( if installed ) and / or the Internal Alarm Buzzer to indicate the ALARM status ( see Fn 29 ).
The temperature may be displayed in Fahrenheit units ( Fn 15 disabled ) or in Celsius units ( Fn 15 enabled ).
The temperature display resolution is normally 1F ( or 1C ), but in the displays with at least 6 digits it is possible to increase
the resolution to 0.1F ( or 0.1C ). This feature is controlled by the function Fn 19.
TEMPERATURE PROBE type selection
The system can operate with two different types of NTC temperature probes specified as 50 Kohm or 100 Kohm , depending
upon the setting of the function Fn 93. Enable this function only if 100 Kohm probes are installed.
Note, that the higher resistance probe responds better to higher temperatures, while the lower resistance probe is better for
sensing of lower temperatures.

NOTE, that the function Fn 71 may be used to cause the system to NOT AVERAGE the temperature readings. This will
result in faster reaction to the temperature changes, but at the same time, the readings may become less stable.

CONTROL RELAY Operation in LOW/HIGH TEMPERATURE ALARM application
The Internal Relay can be controlled by the Low/High Temperature Alarm ONLY when the function Fn 37 is NOT ENABLED.
The Internal Control Relay operates in several different modes depending upon the setting of the function Fn 18 and Fn 16.
1.
When Fn 18 is enabled, the Internal Relay will be switched OFF when the Temperature ALARM occurs and ON
when there is NO ALARM condition.
2.
When Fn 18 is NOT ENABLED, the Internal Relay will ONLY be switched OFF in response to the HIGH
Temperature ALARM and ON when the Temperature is lower than the HIGH ALARM preset, even if it is lower
than the LOW ALARM preset.
When the RELAY LATCHING is enabled (by enabling the function Fn 16), once energized, it will remain ON even if the
temperature falls back within the NO-ALARM range. The relay may be reset manually by pressing the CLR key twice while
the temperature is NOT in the Alarm range.

Alternately, a 50 kohm to 100 kohm resistor may be connected instead.
PROGRAMMABLE MULTI—EVENT HEAT / COOL THERMOSTAT
( Optional Feature )
In all temperature monitoring or control configurations the function Fn 61 must be enabled.
The Programmable, Multi-Event Thermostat is enabled by enabling the function Fn 52.
The option # 714B is for either Heating or Cooling control and incorporates only one probe and one internal relay. The relay
is usually SPDT type with both, the Normally Open and Normally Closed contacts, available at the back panel terminal.
The option # 714C is for Heating and Cooling control and incorporates two probes and two internal relays. This option
includes the auto change-over function for Heat—Cool.
Models with two probes can be ordered either with one probe installed in the clock housing or optionally, with both probes
connected externally to the terminal block on the back panel .
Models with two relays can be ordered with either two Normally Open or two Normally Closed SPST contacts or with two
SPDT contacts, or any combination thereof.
The Programmable Thermostat may be preset for up to 32 events, separately for each of the 7 days of the week,
repeated each week . Total of up to 224 events per week.
The Programmable Thermostat mode allows for programming of the time instances (hours and minutes of the day and
weekday) and the Target Temperature for each event.
All programmed data is stored in the internal, non-volatile memory which is retained even without the supply power.
Programming of THERMOSTAT EVENTS
When the function Fn 52 is enabled, the thermostat may be programmed at any time during the regular clock operation and
DOES NOT require invoking of the programming mode.
1.
Press the SET key at any time during the normal clock operation.
The display will show “MANU” or “AUTO” text momentarily.
A) If in the “AUTO” mode, this will be followed by the Weekday and the Event number for that day.
NOTE: Pressing the “STOP” key at this time will invoke the MANUAL mode of operation.
B) If in the “MANU”al mode, the current preset temperature will follow.
NOTE: Pressing the “STRT” key at this time will invoke the AUTO mode of operation.
2.
A) If in the “AUTO” mode, the event number will flash to indicate that it is active for selection. Use UP and DN keys
to select the event number for that day.
B) If in the “MANU” mode, the preset temperature will flash to indicate that it is active for selection. Use UP and DN
keys to change the setting.
3.
A) If in the “AUTO” mode, to move the cursor to Weekdays press the NXT key. Use UP and DN keys to select the
day and then press the NXT key. The display will show the current Target Temperature for this event. Note: If this
value was never stored before, it may be either very low or very high. Pressing the UP or DN key in the next step
will put the value within the correct range.
B) If in the “MANU” mode, GO TO STEP 4.
4.
Using the UP and DN keys, set the required Target (Preset) Temperature.

The display will show the hour and the minute (HH:MM) of the event that day. Using UP and DN keys set the
required time of the event. To move the cursor press the NXT key.
6.
When satisfied with the event presets, press the HOLD key to store the data in memory.
MAKE SURE that this is done WHILE either the Temperature or the event Hours:Minutes is on the display. If it is
not so, the OLD data will be stored in memory.
7.
The display will flash the text: “Strd“ momentarily to indicate that the programmed data has been stored in the
memory.
8.
Press the NXT key to go back to Step 2 in order to continue programming of other events
or
If finished, wait a few seconds for the system to return to the Normal Operating Mode. The thermostat program will
start executing automatically.
IMPORTANT NOTES
A)
In both, the “AUTO” and the “MANU” modes:
In order to ensure proper operation of COOLING and HEATING, the Auto Switch-Over limits must be programmed.
This is done by programming the presets for SUNDAY Events 30 and 31 . Programming of those events must be
performed in the “AUTO” mode.
- The COOLING switch-over temperature limit ( SUNDAY event 31 ) is the temperature ABOVE which the Cooling
relay will be energized and only when the Target Temperature is lower than the temperature sensed by the probe.
- The HEATING switch-over temperature limit ( SUNDAY event 30 ) is the temperature BELOW which the Heating
relay will be energized and only when the Target Temperature is higher than the temperature sensed by the probe.
B)
If ONLY HEATING or ONLY COOLING control is required :
- If only HEATING control is required, the HEATING switch-over temperature limit ( SUNDAY event 30 ) must be
programmed as lower than any temperature ever expected and the COOLING switch-over temperature limit ( SUNDAY
event 31 ) as higher than any temperature ever expected .
- If only COOLING control is required, the COOLING switch-over temperature limit ( SUNDAY event 31 ) must be
programmed as lower than any temperature ever expected and the HEATING switch-over temperature limit ( SUNDAY
event 30 ) as higher than any temperature ever expected .
C)
The Target Temperature for the “MANU” mode:
The target temperature for the “MANU” mode is stored in SUNDAY event 29 . It may be preset in either the “MANU” or
the “AUTO” mode.
Note, that the “MANU” mode is also using the HEATING and COOLING Auto Switch-Over limits ( as preset for
SUNDAY Event 30 and 31 ) as its operating limits. Programming of those events must be performed in the “AUTO”
mode.
D)
The order in which the thermostat is searching for active events is from event “00“ thru event “31“. The search is
performed at 00 seconds of each minute of the clock real time. First encountered active event shall be executed and
further search shall be aborted until the next minute of the real time clock reading. Therefore, if more than one event for
the day has the same time as any other, only the younger (in order) event number shall be executed. This may have
application in deactivating unused events by setting them as identical to the highest used event number for the day.
E)
When the Supply Power is removed between the event times, after the power is restored the thermostat will SEARCH
BACK all active events that should have been executed. This search is performed in the REVERSED ORDER: from
events 31 thru 00 of each day. The most recent, valid event will be executed. Therefore, care must be taken when
programming the thermostat, so that the unused events in each day either have -40F(C) set as the Target Temperatures
or the OLDEST event number for each day is copied into the unused events for that day.
F)
SYSTEM WARM-UP :
During the first 5 minutes after the system Power-up, the temperature readings may show unreal values. The system will
correct the readings after the warm-up time.

INTERNAL RELAYS CONTROL :
The internal relays CONTACTS are enabled to change states only ONCE every 30 SECONDS.
The contact designated as “COOL” will be energized when a demand for cooling (Air-Conditioning) is detected.
The contact designated as “HEAT” will be energized when a demand for heating is detected.
Both relays contacts are completely isolated from each other and from all other circuits.
STEADY Light in the upper-left corner of the display indicates that the “HEAT” relay is energized.
BLINKING Light in the upper-left corner of the display indicates that the “COOL” relay is energized.
These lights may be active ONLY when the temperature is on the display.
To DISABLE the PROGRAMMABLE THERMOSTAT operation:
Disable the function Fn 52 . (see FUNCTION SETUP Procedure section in the Manual ). All previously preset events data
will be retained in the memory unaffected.
USEFUL TIP
During the Normal Operation, when the thermostat is set to operate in the AUTO or MANU mode, it is possible to find out
which event is currently being executed and with what presets.
To do that press the SET key on the remote at any time. The most recently executed event will be displayed. Use the NXT
key to scroll through the day, temperature and hrs:minutes for that event.
NOTE that at this point the system will also accept new settings for this and other events.
IMPORTANT NOTE:
If a probe is installed in, on or near the display enclosure, due to its location, its temperature may be slightly affected by
the heat generated by the display and the electronics. Therefore, wiring a probe externally, if possible, in an area in
which the temperature is to be controlled, is preferred.
Also, if an internal probe is installed in the enclosure, then pulling the probe further out of its shield may lessen its
sensitivity to the heat generated inside the display enclosure.
If the model has two probes, to switch the thermostat control to the External probe, make sure that the function Fn 27 is
DISABLED.
CAUTION: Avoid exposing the temperature probes to the direct sunlight as this will dramatically affect the readings.
To PROTECT the PROGRAM AGAINST ANAUTHORIZED ACCESS :
By ENABLING the function Fn 63 ( see the FUNCTION SETUP Procedure section in the Manual ) all access to the clock
functions and to the Thermostat program via the remote control will be LOCKED-OUT. All other operation will however
remain unaffected.
In order to regain the control via the Remote Controller, disconnect the supply power for 2 seconds and then restore the
power and within 30 seconds Disable the function Fn 63.
All remote access to the clock will be unlocked.
