NOVATEK-ELECTRO MCK-108
3.1.4 When working with one pump, connect the magnetic starter (hereinafter referred to as MS) of the electric
motor according to Figure 2 and turn the switch 1
– 2
to " 1 " position. When working with two pumps, connect MS of
the electric motor according to Figure 7 and turn the switch 1
– 2
to " 2 " position.
3.1.5 When working in the drainage mode, turn the switch Drn - FI (Drainage
– Filling) to "
Drn " position.
3.1.6 When working in the filling mode with level sensors, turn the switch CPG
– S.L.
(CPG
– Level Sensor) to
" S.L ." (Level Sensor) position and turn the switch Drn - FI (Drainage
– Filling) to "
FI " (Filling) position.
3.1.7 To connect the pressure sensor to MCK-108, one must connect the following items by using Figure 1 and
Figure 3:
– contacts "1а" and "1b" on CPG with contact "12" on MCK-108;
– contact "2" on CPG with contact "10" on MCK-108;
– contact "3" on CPG with contact "9" on MCK-108;

3.1.8 When working in the filling mode with the pressure sensor, turn the switch CPG
– S.L.
(CPG
– Level
Sensor) to
“
CPG " position and turn the switch Drn - Fi (Drainage
– Filling) to "
Fi " position.
3.1.9 By using the handle
Тhs
, adjust the necessary response delay time, which shall exclude false level
sensor tripping due to a possible hydraulic shock.
ATTENTION! Don't make excessive efforts when performing adjusting operations.
3.1.10 Turn the handle Sens to the position, corresponding to the measured liquid resistance.
3.1.11 By using the handle
Таr
, adjust the necessary AR time, after deactivation of the pump motor due to a dry
run failure. Setting the AR time depends on either the time of filling the well or the liquid flow from the tank.
