Trouble and abnormality shooting

Please be aware that magnetic fields or residual magnetism may cause interference to the flowmeter which may result in damage if they are used near the installation site. The purchaser must determine the applicability of the product for its desired use and assumes all risks in connection therewith. LORRIC assumes no responsibility or liability for any omissions or errors in connection with the use of its products.

The alarm used to detect paddle damage or loss is intended to assist on-site operators to find out what is causing equipment abnormalities. Because there are a myriad of variables involved with on-site operation and magnetic fields that come from other equipment, the alarm function is liable to fail. Please do not take the alarm function as a single source for monitoring your flow system. Please contact LORRIC for advanced help.

Trouble shooting

Messages or phenomena

Possible causes

Solution

Error of paddle wheel

  1. Paddle damaged by foreign objects or external force

  2. Magnet demagnetization caused by the environment.

  1. Stop the operation of working piping system.

  2. Empty fluid the in pipe.

  3. Remove the device.

  4. Take off paddle set for confirming the condition.

    1. If the paddle wheel is damaged or lost, please contact LORRIC to purchase a replacement paddle set.

    2. If the exterior of paddle wheel looks fine, the cause of the problem might be the demagnetization of the paddle wheel caused by the environment. It is able to use the H05 parameter to initialize the paddle wheel flowmeter. If after initializing by the H05 parameter, the result is “initialization failure”, please contact LORRIC to purchase a replacement paddle set.

  5. Exclude the factors which cause abnormal paddle wheel.

  6. After replacing the new paddle set, please initialize the paddle wheel with the H05 parameter.

Magnetic field interruption

There is magnetic field interruption around the flowmeter.

Please remove equipment which may generate magnetic fields until the status of the paddle wheel is back to normal. If interference is not able to be excluded, please turn off the alarm when flow volume data is as expected.

4-20mA unable outputted

4-20mA Not enough external external supply voltage provided by communication.

Please make sure that the 4-20mA loop provides power supply as well as the polarity of cable connection is correct or not.

4-20mA abnormal outputtedvalue

4-20mA Outputted value needs to be fine tuned.

Please adjust output current value by set-up parameter E11 and E12.

Excessive Line and measuring impedance.

  1. Please confirm if total loop resistance exceeds usage limit, and if it is replaceable.

  2. Please increase external supply voltage, proper external supply voltage will increase usage limit of total loop resistance.

Wrong set-up outputted parameter.

Please confirm the correction of set-up parameter E06 E07 E08.

RS485 Unable to receive response.

Communication parameter set-up mismatch

Please confirm the correction of set-up parameter E04 E05.

Address conflict

Please confirm that there is only one piece of equipment at a specified address.

Abnormal calendar battery

Calendar battery is low.

Please refer to the page of mechanical and electrical installation, take off upper housing and replace battery.

Other abnormalities

  1. Please use parameter H06 to reset to default settings.

  2. Please initialize the paddle wheel with H05 parameter.

Abnormality shooting

Phenomenas

Possible causes

Solutions

Flow volume is repeated as zero.

Unable to keep rotating paddle wheel caused by too slow flow speed.

Please confirm the flow speed range on the main page. If flow speed is under 0.3 or repeated as zero, there are 2 solutions as below.

  1. Please increase flow speed slightly if possible.

  2. If the flow speed is not able to be increased, please turn on parameter A08. This function will increase response time, but the flow volume will be 0 less frequently.

Foregn objects will cause Intermittent deceleration.

  1. Stop the operation of working piping system.

  2. Empty fluid the in pipe.

  3. Remove the device.

  4. Take off the paddle set for confirming the condition and remove foregn objects.

    1. If the paddle wheel is damaged or lost, please contact LORRIC to purchase a replacement paddle set.

  5. Exclude the factors which cause abnormal paddle wheel.

Intermittent shut-down problem.

Unstable power supply

Please confirm supply voltage and current is within the range.
