3.2. ELECTRICITY
3.2.1. ELECTRIC CONNECTION OF THE CONTROL UNIT
The system is supplied ready to be used in the installations. There is no need for any power adaptor, but we recommend
installing a motor protector before connecting to the mains, to avoid a possible surge in voltage that would severely damage
Microdos Pooltec’s electronics (Such problems are not covered under the guarantee). (See illustration).
Place the power cables of the control unit to the electrical box of the pump with protector or plugging into an outlet of the engine
room.
1. Microdos Pooltec control unit 3. Contactor 5. Recirculation pump
2. Overload switch 230 Vac 4. Motor guard
We remind installers that Microdos POOLTEC has only one power input, which goes from the control unit to the main power
grid. We must be careful
not to connect the pump or any component to the main power supply.
The power supply to the peripheral circuit systems is provided as follows:
PERISTALTIC PUMPS (MP2-B) for pH, Redox, Peroxide ………………………………….………….... Direct outlet to the mains (*)
PERISTALTIC/SOLENOID PUMPS (MP2-HT/ME3) for pH, Redox, Peroxide ………….………... Direct to the main power grid
RECIRCULATION PUMP ........................................................................................................... Dry contact (**)
(*) The voltage output depends on the mains input. If the mains are 117VAC, the output to the peristaltic pump will be
117VAC; if the mains is 230VAC, the peristaltic pump output will be 230VAC.
(**) POOLTEC’s cut-off relay is 5 amps at 230VAC: we therefore need to use contactors or motor shields with a consumption
coil less than or equal to 5 amps at 230VAC.
Since Microdos Pooltec is a pool manager, it should control and command the recirculation pump.
IMPORTANT: It is also possible to choose not to manage the recirculation pump working time (NO PROGRAM).
In this case, however, Microdos Pooltec cannot allow the functioning of HEATING.
