NOVATEK-ELECTRO MCK-108
3.2.1.2 Operation in the automated
filling mode
with the pressure sensor
In the initial state (if the movable contact is located between the
UL
and
LL
contacts), when starting the power
supply, the electric motor will not be activated.
When closing the movable contact with the contact of the
UL
upper setting, the automatic deactivation of the
electric motor takes place.
When closing the movable contact with the contact of the
LL
lower setting, the automatic activation of the
electric motor takes place and the cycle is repeated.
3.2.1.3 Operation in the automated
filling mode
with the level sensors
In the initial state (in case there is no liquid in the tank), when starting the power supply, the pump electric
motor will be activated automatically.
When the liquid level reaches the
UL
sensor, the automatic deactivation of the electric motor takes place.
When the liquid level in the tank is lower than the
LL
sensor, the automatic activation of the pump electric
motor takes place to feed the liquid into the tank and the cycle is repeated.
3.2.1.4 Operation in the automated
drainage mode
with the level sensors
In the initial state (in case the liquid level in the tank is lower than the
UL
sensor), when starting the power
supply, the pump electric motor will not be activated.
When the liquid level reaches the
UL
sensor, the automatic activation of the pump electric motor takes place.
When the liquid level in the tank is lower than the
LL
sensor, the automatic deactivation of the pump electric
motor takes place and the cycle is repeated.

3.2.2 MCK-108 operation with two pumps
For operating MCK-108 with two pumps, one must connect the contactor starter of the second pump according to
Figure 7.
In the automated operation modes of MCK-108 with two pumps, the operation logic of the device is preserved, but
the functional relay is used to control the electric motor of the second pump and, subsequently, does not respond to
emergency conditions.
Activation of the electric motors of the pumps (activation of the functional relay and the pump relay) takes place in
turn after each deactivated of one of them.
