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.
