Multi-function time relay
Characteristic
Description
EN
• Multi-function time relay for universal use in automation, control and regulation
or in house installations.
• All functions initiated by the supply voltage, except for the asher function, can
use the control input to inhibit the delay (pause).
• Relay mode selection - according to the set function, permanently closed,
permanently open, function of memory latch with delay (ZTM 1) / switching of
the second relay according to supply voltage (ZTM 2).
• Universal supply voltage AC/DC 12 – 240 V.
• Time scale 50 ms - 30 days divided into 10 ranges: (50 ms - 0.5 s / 0.1 s - 1 s /
1 s - 10 s / 0.1 min - 1 min / 1 min - 10 min / 0.1 hr - 1 hrs / 1 hrs - 10 hrs / 0.1 days -
1 day / 1 day - 10 days / 3 days - 30 days).
• Output contact:
ZTM 1: 1x changeover / SPDT 16 A
ZTM 2: 1x changeover / SPDT 16 A, 2x changeover / DPDT 8 A
• Multifunction red LED ashes or shines depending on the operating status.

When the supply voltage is applied, the relay is open. If the control contact is closed,
the relay closes and the time delay T starts. It does not matter the length of the control
pulse. When the timing is complete, the relay opens. If the control contact is closed
during timing, the relay opens immediately. Each time the control contact closes
during relay timing, it changes status.
The second relay switches according to the supply voltage.
The rst relay switches according to the function (a-j) set by the trimmer FUNC.

Warning
Device is constructed for connection in 1-phase AC/DC 12- 240 V main alternating current
voltage and must be installed according to norms valid in the state of application.
Connection according to the details in this direction. Installation, connection, setting
and servicing should be installed by quali ed electrician sta only, who has learnt
these instruction and functions of the device. This device contains protection against
overvoltage peaks and disturbancies 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 disturbancies 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 electro-magnetic 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 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 of transportation, 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, or store in
protective dump.

When the supply voltage is applied, the relay is open. When the control contact is
closed, the relay closes and the time delay T begins. When the control contact is
opened, the relay closes and the time delay T begins. If the control contact is open
during timing, the relay remains closed for 2T. When the timing is complete, the relay
opens. Any other change of control contact status during timing is ignored.
When the supply voltage is applied, the relay is open. If control contact is closed, time
delay T starts. When the control contact is opened, a new time delay T begins. If the
control contact is open during timing, the relay closes at the end of the timing and
opens the relay after the new time delay. Any other change of control contact status
during timing is ignored.
