If your PEDROLLO Water Pump VSP displays a “DRY RUN” alarm at start-up, check the COSFI MIN setting in the CONF.MOTOR menu. For the 400V three-phase model, ensure the pump rotates correctly. Also, verify the connection and operation of the flow sensor connected to IN1, ensuring IN1 is OFF. Note this is a self-resetting alarm with repeated attempts for REC TIME.
What to do if PEDROLLO Water Pump VSP shows a “CIRCU.OPEN” alarm on pressure transducer at start-up?
If the PEDROLLO Water Pump VSP goes to protection due to “CIRCU.OPEN” alarm on the pressure transducer upon start-up, check that the transducer is correctly connected and that the cables are not damaged. Also, check the transducer state. Note that this is a self-resetting alarm.
Why does my PEDROLLO Water Pump VSP show a “PFC.IN.LOW” alarm on start-up?
If the PEDROLLO Water Pump VSP goes to protection due to input undervoltage alarm “PFC.IN.LOW”, check if the input voltage has decreased, or if the VSP is incorrectly connected to a power system (e.g., 230V instead of 400V). Also, inspect the condition of the power cables. Note that this is a latching alarm.
Why does my PEDROLLO Water Pump VSP show a “MIN.VOLTAGE” alarm on start-up?
If the PEDROLLO Water Pump VSP goes to protection due to input undervoltage alarm “MIN.VOLTAGE”, check if the input voltage has decreased, or if the VSP is incorrectly connected to a power system (e.g., 230V instead of 400V). Also, inspect the power cables for any issues. Note that this is a latching alarm.
Why does my PEDROLLO Water Pump VSP show a “PFC.IN.HIGH” alarm on start-up?
If the PEDROLLO Water Pump VSP goes to protection due to input overvoltage alarm “PFC.IN.HIGH”, check if the input voltage has increased, or if the VSP is incorrectly connected to a power system (e.g., 400V instead of 230V). Also, inspect the power cables for any issues. Note that this is a latching alarm.
Why does my PEDROLLO Water Pump VSP show a “MAX.VOLTAGE” alarm on start-up?
If the PEDROLLO Water Pump VSP goes to protection due to input overvoltage alarm “MAX.VOLTAGE”, check if the input voltage has increased, or if the VSP is incorrectly connected to a power system (e.g., 400V instead of 230V). Also, inspect the power cables for any issues. Note that this is a latching alarm.
Why does my PEDROLLO Water Pump VSP show a “MAX CURRENT” alarm on start-up?
If the PEDROLLO Water Pump VSP goes to alarm mode for “MAX CURRENT” protection upon start-up, you should first check the maximum current setting in the CONF.MOTOR menu. Also, verify that the motor being used is working correctly. Note that this is a latching alarm.
How to reset a non-latching alarm on a PEDROLLO Water Pump?
To reset a non-latching alarm on the PEDROLLO Water Pump, follow these steps: * Press the button. * Look for the message 'CLEAR ERROR? (TYPE OF ALARM *)' on the display. * Press the key to definitively reset the alarm.
What to do if PEDROLLO VSP Water Pump is in automatic mode but the pump is not enabled?
If the PEDROLLO Water Pump VSP is in automatic mode but the pump is not enabled, check the configuration of the inputs IN1, IN2, and the PRESSURE TRANSDUCER in the ADVANCED PARAMETERS MENU. Also, check that the inputs are working correctly, such as the pressure switch connected to IN1, IN2, or the PRESSURE TRANSDUCER.
How to fix LCD ERROR alarm on my PEDROLLO VSP Water Pump?
If the display of your PEDROLLO Water Pump does not switch on or shows an "LCD ERROR” alarm, check that the FLAT cable is correctly connected and is not damaged.
