Why SOFT LED is on but the pump motor does not operate in Hach SP-510?
If the SOFT LED is lit but the pump motor isn't running, check that the line voltage is within the specified range. Also, verify the line voltage selector switch is set to the correct voltage. Ensure the motor cable is properly connected. If the motor still doesn't operate, it may need to be replaced.
What to do if display lights and the pump motor does not operate on Hach Monitor?
If the display lights up but the pump motor doesn't operate on your Hach Monitor, here are a few things to check: 1. Low operating power: Verify the line voltage is within specifications. 2. Incorrect line voltage selector switch setting: Check the line voltage selector switch position. 3. Motor cable not connected: Check the motor cable connection to the circuit board. 4. Defective motor: Replace the motor.
How to troubleshoot a Hach Monitor when the display doesn't light and the pump motor isn't operating?
If the display does not light and the pump motor is not operating on your Hach Monitor, check the power switch position, fuse, and power cord connections to ensure they are properly connected.
What to do if display doesn't light but the pump motor operates on Hach Monitor?
If the display doesn't light, but the pump motor operates on the Hach Monitor, the problem may be with the power supply. Replace the circuit board.
Why does my Hach Monitor show hard water with a continuous red LED?
If the flow rate is not correct, the Hach Monitor may show hard water and a continuous red LED. A flow rate that's too low can prevent the sample cell from completely flushing out the color, leading to a zero reading. A flow rate that's too high can cause water to bypass the pinch block, diluting the color. Ensure the flow rate is set to 200 mL/minute. Additionally, check the sample line in the pinch block to ensure it's not pinched off. Adjust the flow rate to 200 mL/minute while observing a steady water stream. Also, make sure the pressure plate of the pinch block is not overtightened and inspect the back of the pinch blocks for grooves.
What happens if no stir bar is installed in Hach Measuring Instruments?
If no stir bar is installed or more than one stir bar is installed in your Hach Measuring Instruments: * Make sure that a stir bar is installed. * Use a paper clip to retrieve the stir bar from the colorimeter and make sure that multiple stir bars are not installed. * If the stir bar does not operate, mix the sample manually after the reagents have been added. Use the end of a wooden Q-tip and mix the reagents approximately for 10 seconds. If the instrument gets a reading, the mixing is not sufficient. Replace the stir coil. Additional information is available on the manufacturer's website.
Why is the SOFT LED flashing continuously on Hach SP-510?
If the SOFT LED is flashing continuously for more than 5 minutes after powering on your Hach Measuring Instruments, let the instrument complete the cycle. Ensure the motor is operating. Power off and then on, waiting 5 minutes. If the issue persists, contact technical support, as it could indicate a blockage in the optical path or a faulty optical switch.
Why is the reading continually high on Hach SP-510 Measuring Instruments?
If the reading is continually high and the HARD LED is on for your Hach Measuring Instruments, refer to Troubleshooting for a hard reading on page 22. If the problem continues, cycle power, examine all power connections and fuses, replace the circuit board, or contact technical support.
How to fix a pinched sample line in the pinch block of Hach SP-510?
If the sample line is pinched off in the pinch block of your Hach Measuring Instruments, follow these steps: * Pull the sample line from the colorimeter, being aware that water in the line may leak out. Examine and adjust the flow rate to 200 mL/minute while the line is pinched, ensuring a steady water stream. * Make sure the pressure plate of the pinch block isn't overtightened. * Inspect the back of the pinch blocks for grooves.
How to set the flow rate for accurate readings on Hach Measuring Instruments?
To ensure the sample cell in your Hach Measuring Instruments flushes completely, set the flow rate to 200 mL/minute. This prevents a zero reading caused by insufficient flushing or dilution from bypassing the pinch block.
