Functions
| Function | Description |
|---|---|
| ON DELAY | When the input voltage U is applied, timing delay t begins. |
Relay contacts R change state after time delay is complete.
Contacts R return to their shelf state when input voltage U is
removed. Trigger switch is not used in this function.
SINGLE SHOT| Upon application of input voltage U, the relay is ready to
accept trigger signal S. Upon application of the trigger signal S,
the relay contacts R transfer and the preset time t begins. During
time-out, the trigger signal S is ignored. The relay resets by
applying the trigger switch S when the relay is not energized.
INTERVAL ON| When input voltage U is applied, relay contacts R change state
immediately and timing cycle begins. When time delay is complete,
contacts return to shelf state. When input voltage U is removed,
contacts will also return to their shelfstate. Trigger switch is
not used in this function.
FLASHER – OFF first| When input voltage U is applied, time delay t begins.
When time
delay t is complete, relay contacts R change state for time delay
t. This cycle will repeat until input voltage U is removed. Trigger
switch is not used in this function.
ON/OFF DELAY| Input voltage U must be applied continuously. When trigger
switch S is closed, time delay t begins. When time delay t is
complete, relay contacts R change state and remain transferred
until trigger switch S is opened. If input voltage U is removed,
relay contacts R return to their shelf state.
FLASHER – ON first| When input voltage U is applied, relay contacts R change
state
immediately and time delay t begins. When time delay t is complete,
contacts return to their shelf state for time delay t. This cycle
will repeat until input voltage U is removed. Trigger switch is not
used in this function.
MEMORY LATCH| Input voltage U must be applied continuously. Output changes
state with every trigger switch S closure. If input voltage U is
removed, relay contacts R return to their shelf state.
OFF DELAY| Input voltage U must be applied continuously. When trigger
switch S is closed, relay contacts R change state. When trigger
switch S is opened, delay t begins. When delay t is complete,
contacts R return to their shelf state. If trigger switch S is
closed before time delay t is complete, then time is reset. When
trigger switch S is opened, the delay begins again, and relay
contacts R remain in their energized state. If input voltage U is
removed, relay contacts R return to their shelf state.
Warning: Ensure proper understanding of the product manual before usage to avoid any misuse or damage.

Warning
The device is constructed for connection in 1-phase network AC 12 – 240 V and
must be installed in accordance with regulations and standards applicable in
the country of use. Installation, connection, setting and servicing should be
installed by qualified electrician staff only, who has learned this
instruction and the functions of the device. This device contains protection
against overvoltage peaks and disturbances in supply. For correct function of
the protection of this device there must be suitable protections of higher
degree (A,B,C) installed in front of them. According to standards elimination
of disturbance must be ensured. Before installation the main switch must be in
position “OFF” and the device should be de-energized. Don´t install the device
to sources of excessive electromagnetic interference. By correct installation
ensure ideal air circulation so in case of permanent operation and higher
ambient temperature the maximal operating temperature of the device is not
exceeded. For installation and setting use a screw-driver cca 2 mm. The device
is fully-electronic – installation should be carried out according to this
fact. Non-problematic function depends also on the way oftransportation,
storing and handling. In case of any signs of destruction, deformation, non-
function or missing part, don´t install and claim at your seller it is
possible to dismount the device after its lifetime, recycle it, or store in
the protective dump.
Functions
ON DELAY
When the input voltage U is applied, timing delay t begins. Relay contacts R
change state after time delay is complete. Contacts R return to their shelf
state when input voltage U is removed. Trigger switch is not used in this
function.
INTERVAL ON
When input voltage U is applied, relay contacts R change state immediately and
timing cycle begins. When time delay is complete, contacts return to shelf
state. When input voltage U is removed, contacts will also return to their
shelf state. The trigger switch is not used in this function.
FLASHER – OFF first
When input voltage U is applied, time delay t begins. When time delay t is
complete, relay contacts R change state for time delay t. This cycle will
repeat until input voltage U is removed. Trigger switch is not used in this
function.
FLASHER – ON first
When input voltage U is applied, relay contacts R change state immediately and
time delay t begins. When time delay t is complete, contacts return to their
shelf state for time delay t. This cycle will repeat until input voltage U is
removed. The trigger switch is not used in this function.
OFF DELAY
Input voltage U must be applied continuously. When trigger switch S is closed,
relay contacts R change state. When trigger switch S is opened, delay t
begins. When delay t is complete, contacts return to their shelf state. If
trigger switch S is closed before time delay t is complete, then time is
reset. When trigger switch S is opened, the delay begins again, and relay
contacts R remainin their energized state. If input voltage U is removed,
relay contacts R return to their shelf state.
SINGLE SHOT
Upon application of input voltage U, the relay is ready to accept trigger
signal S. Upon application of the trigger signal S, the relay contacts R
transfer and the preset time t begins. During time-out, the trigger signal S
is ignored. The relay resets by applying the trigger switch S when the relay
is not energized.
SINGLE SHOT falling edge
Upon application of input voltage U, the relay is ready to accept trigger
signal S. Upon application of the trigger signal S, the relay contacts R
transfer and the preset time t begins. At the end of the preset time t, the
relay contacts R return to their normal condition unless the trigger switch S
is opened and closed prior to time out t (before preset time elapses).
Continuous cycling of the triggerswitch S at a rate faster than the preset
time will cause the relay contacts R to remain closed. If input voltage U is
removed, relay contacts R return to their shelf state.
ON/OFF DELAY
Input voltage U must be applied continuously. When trigger switch S is closed,
time delay t begins. When time delay t is complete, relay contacts R change
state and remain transferred until trigger switch S is opened. If input
voltage U is removed, relay contacts R return to their shelf state.
MEMORY LATCH
Input voltage U must be applied continuously. Output changes state with every
trigger switch S closure. If input voltage U is removed, relay contacts R
return to their shelf state.
PULSE GENERATOR
Upon application of input voltage U, a single output pulse of 0.5 seconds is
delivered to relay after time delay t. Power must be removed and reapplied to
repeat pulse. Trigger switch is not used in this function.
