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.
On the external potentiometer for fi ne adjustment of time to adjust 8 s, check accuracy
(eg. a stopwatch).
On rough time setting, set potentiometer to originally desired scale 1 - 10 hours, leave
a fi ne setting as it is.
Potentiometer
It is possible to connect the external operating potentiometer up to the distance of
maximally 10 meters (32.8 ft.) from relay CRM-2HE, for example in switchboard. The external
potentiometer has cover IP65 from the front side and IP20 from the rear side. It is absolutelly
necessary to connect potentiometer with the device in correct way. The terminals on the
device must be connected to the equally marked terminal on the potentiometer.

Warning
Device is constructed for connection in 1-phase installation of AC/DC 12-240 V main
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.
