NOVATEK-ELECTRO
1
– LED
Func
(Function) glows green if the functional relay contact is closed;
2
– LED
Pump
glows green if the pump relay contact is closed;
3
– Switch
Dr
– Fi
(Drainage
– Filling) sets either the drainage or the filling mode;
4
– Switch
CPG
– S. L.
(CPG
– Level Sensor) sets either the contact pressure gauge (CPG) or level sensors mode;
5
– Switch
Off
-
DR
allows operation of the dry run sensor;
6
– Switch
Off
-
EL
allows operation of the emergency level sensor;
7
– Switch
1
– 2
sets the number of pumps in use;
8 - Handle
Тhs
adjusts the sensor response delay time (hydraulic shock);
9
– Handle
Таr
adjusts the automatic reset (AR) time after failure of
DR
sensor;
10
– Handle
Sens
adjusts sensor resistance for various environments;
11
– LED
DR
(Dry Run) glows green if the liquid level is higher than the dry run sensor; glows red if the liquid level is
lower than the dry run sensor; and blinks green if the liquid level is higher than the dry run sensor, but AR time has not
elapsed yet; does not light up if switch
Off
–
DR
is
in
“Off”
position.
12
– LED
LL
(Lower Level) glows green the liquid level is higher than the lower level sensor. If the liquid level is
lower than the lower level sensor, in the filling mode it glows red, while in the drainage mode it blinks green;
13
– LED
UL
(Upper Level) glows red if the liquid level is higher than the upper level sensor;
14
– LED
EL
(Emergency Level) glows red if the liquid level is higher than the emergency level sensor, if the liquid
level is lower than the emergency level sensor or switch
Off
– EL
is in “
Off”
position LED does not glows.

Operation conditions
- Operating temperature range
– from -35 to +55 ºC;
- Atmospheric pressure
– from
84 to 106,7
кPa;
-
Relative humidity 30 … 80 % (at +25 ºС temperature).
If the temperature of the product after transportation or storage differs from the environment temperature at
which it is expected to operate, then before connection to electric mains keep the product under the operating
conditions within two hours (because the product elements may have moisture condensation).
ATTENTION!
The device is not intended for operation in the following conditions:
−
Significant vibration and shocks;
−
High humidity;
−
Aggressive environment with content in the air of acids, alkalis, etc., as well as severe
contaminations (grease, oil, dust, etc.).
