Switching Panel for 2 Electric Pumps Cabinet T

Apresentação

- Plastic Box 460x448x160 mm in ABS gray RAL7035 and lid with transparent window.
- Motor circuit breakers and contactors from selected brands.
- Toggle relay for toggle and simultaneity command.
- MCS-12 module that allows automatic, manual or off operation, independently controlled by each pump using a 3-position switch.
- MCS-AL module with audible and luminous alarm included and with a 3-position switch, allowing to keep the audible alarm in automatic operation, test or off, without interfering with the luminous alarm.
- Connection with reduced voltage (12V) for remote start (C31-C32, C41-C42) and stop (C21-C22) command of motors (pressure switch, float or other).
- Connection with reduced voltage (12V) for remote safety command (C11-C12) (pressure switch, float or other).
- Connection with reduced voltage (12V) for remote alarm command (C51-C52) (pressure switch, float or other).
- Protection of the command circuit through a circuit breaker.
- Protection of the power circuit against short circuits and overloads through a motor circuit breaker.
- Indication of command circuit voltage presence (yellow LED on the toggle relay).
- Individual indication of motor on (green LED's on the MCS-12 module).
- Individual indication of thermal trip (red LED's on the MCS-12 module).
- Alarm on indication (red LED on the MCS-AL module).

Modo de Funcionamento

Once all the connections have been made correctly, the motor circuit breakers must be adjusted according to the rated currents of the motors.

With the switches on the MCS-12 module in position (AUT), whenever the level reaches the start command for the 1st pump (C31-C32), one of the pumps will be turned on alternately, only turning off when the level drops to the stop level ( C21-C22). If the level rises to the simultaneous level (C41-C42), the 2 pumps will start operating simultaneously, only switching off both when the level drops to the stop level (C21-C22).

Whenever the alarm command (C51-C52) closes, the alarm LED and the sound alarm of the MCS-AL module will be turned on, and the latter can be turned off using the respective switch.

Opening the general safety command (C11-C12) switches off the pumps, regardless of the start and stop command indications and the MCS-12 module switches (if in automatic). If you do not intend to use the safety command, it must be closed using a "shunt".

With the control circuit switch in position (I), the corresponding pump turns on, regardless of the status of the start, stop and safety commands.

The tripping of any of the motor-breakers due to overload or short circuit (red LEDs of the MCS-12 module), causes the corresponding pump to remain off regardless of the indications of any of the commands
