What does 'WARN: PUMP BOX TEMP HIGH' mean on my EBARA Water Pump?
If your EBARA Water Pump displays 'WARN: PUMP BOX TEMP HIGH', the cooling water flow may be reduced, or the ambient temperature may be high. Increase cooling water flow or confirm the ambient temperature (less than 30?).
Why is the circuit protector activated on my EBARA Water Pump?
If the circuit protector is activated on your EBARA Water Pump, it could be due to incorrect wiring or a short circuit. Check the wiring first. If that's not the problem, the pump may have a short circuit, requiring replacement or overhaul.
What to do if EBARA EV-S20N Water Pump shows ALARM: WATER FLOW LOW?
If the EBARA Water Pump displays 'ALARM: WATER FLOW LOW', several issues could be the cause. It might be that the coupler is disconnected, the pressure isn't sufficient, the root valve is closed, the water pipe is clogged, tube fittings are loosened, there's an instrument failure, or the outlet and inlet pipes are reversed. To resolve this: * Connect the coupler if disconnected. * Apply sufficient pressure. * Open the valve if it's closed. * Clean or replace the piping if clogged. * Re-tighten any loose tube fittings. * Replace the instrument if there is an instrument failure. * Connect pipes correctly if they are reversed.
Why is my EBARA EV-S20N Water Pump making abnormal noises and vibrating excessively?
If your EBARA Water Pump is experiencing abnormal noise and excessive vibration, here are a few possible causes: * The adjustment feet may not be applied, so use them. * Some object might be making contact with the outer cover, so remove it. * The fastening screws of the outer cover may have worked themselves loose, so tighten them. * Parts of the pump may be damaged, requiring you to replace or overhaul the pump.
What does 'WARN:PUMP N2 VALVE ERROR' mean on my EBARA Water Pump?
If your EBARA Water Pump displays 'WARN:PUMP N2 VALVE ERROR', the N2 valve may be open. Close N2 valve, which is located at the side of the pump.
What does 'ALARM : BACK PRESS.HIGH' mean on my EBARA EV-S20N?
If your EBARA Water Pump displays 'ALARM : BACK PRESS.HIGH', the exhaust valve may be closed, there may be accumulation of by-products in pipes, or there may be instruments failure. Check the exhaust pipe or replace the instruments.
What does 'ALARM:STARTFAIL ALARM/WARN EXIST' mean on my EBARA Water Pump?
If your EBARA Water Pump displays 'ALARM:STARTFAIL ALARM/WARN EXIST', it could be due to starting during WARNING/ALARM status or instrument failure. Make sure that all starting conditions are met or replace the instrument.
What to do if my EBARA Water Pump shows 'ALARM: WATER LEAKAGE'?
If your EBARA Water Pump displays 'ALARM: WATER LEAKAGE', it could be due to loosened tube fittings or instrument failure. Re-tighten the tube fittings or replace the instrument.
What to do if my EBARA EV-S20N MP does not start when entering external “MP start” signal input?
If the MP on your EBARA Water Pump doesn't start when entering external “MP start” signal input, it might be because “Local” or “COM” mode has been selected, start-up conditions are not satisfied, or there is an instrument failure. Set the switch to “Remote” or satisfy all start-up conditions. If the problem persists, replace the instruments.
What does 'ALARM:BP MOTOR TEMP H.HIGH ALARM:MP MOTOR TEMP H.HIGH' mean on my EBARA EV-S20N?
If the EBARA Water Pump displays 'ALARM:BP MOTOR TEMP H.HIGH ALARM:MP MOTOR TEMP H.HIGH', the cooling water flow may be reduced, or there may be a motor failure. Cool the pump thoroughly and reset it, or replace or overhaul the pump.
