More accurate setting of timing for long periods of time
Example of time setting to 8 hours period:
For rough setting use time scale 1 - 10 s on the potentiomenter.
For fi ne time setting aim for 8 s on potentiometer, then recheck accuracy (using
stopwatch etc).
On rough time setting, set potentiometer to originally desired scale 1 - 10 hours, leave
a fi ne setting as it is.
Warning
Device is constructed for connection in 1-phase 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 qualifi ed electrician staff 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.
