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 count-
down 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
