After doing all the connections properly, the Probomba Relay shall be adjusted accordingly to the motor’s characteristics. The Control Box shall maintain all the signaling OFF until the main switch is switched to the ON position (I), time when the yellow signal lamp for phase presence (~) turns ON.
With the command circuit switch on the automatic mode “AUT”, every time the start/stop command (P11-P12) closes, the probomba relay turns ON (LED’s “PWR”,”COM” and “OUT”) and the soft starter does the soft start of the pump during the previously regulated period of time (green signal lamp).
After this time, the pump will work at nominal speed, doing a soft stop and turning OFF if the start/stop command opens.
If during functioning, the PRObomba relay detects a consumption lower than the minimum parameter, by a period of time (Td) higher than 4 seconds, the pump turns OFF (with soft stop) and it will show on the display, intermittently, the error message for under intensity “EIL” and the remaining period of time (minutes) until the automatic re-start happens.
The automatic re-start will be tried for 3 times, being the two first intervals of 5 minutes (pre-defined value from factory, with the possibility of being changed by the user), and the last re-start tried after 99 minutes, after which the relay will turn OFF, keeping a message for error of under intensity “EIL”.
The re-start of the relay may only be done manually, by pressing the reset button “RST” or by cutting momentarily the supply.
If the maximum intensity limit is exceeded by a period of time (Td) over 4 or 8 seconds, accordingly to the verified overcharge, the pump will turn OFF (with progressive stop), indicating on the display the error message for over intensity “EIH”, and the alarm signaling will turn ON, (red signal lamp and LED “AL” of the Propump relay). The re-start of the relay may be only made manually, by pressing the reset button “RST”, or by cutting momentarily the supply. If the operating time of the pump exceeds the previously regulated period of time, it will be show non the display, intermitently the information "EOH", the elapsed time (minutes) and the value of current. It is also activated the alarm output.
Every time that during operation it is verified that the supply tension is higher than the maximum parameter and lower than the minimum (values pre-defined from factory) for more than 4 seconds, it will be shown on the display of the PROpump relay the message ”EUH” – error by surge of voltage or ”EUL” – error by sub voltage.
The opening of the security command (C11-C12) turns OFF the pump, independently of the indications of the indications of the Start/Stop command. If you do not wish to make use of the safety command, you may close it through a "shunt".
With the command circuit switch on the manual position, the pump starts, independently of the state of the start/stop command and the safety command.
