Trouble and abnormality shooting

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.

Analog current output unable outputted

Abnormal wiring

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

The function is not turned on.

Analog current outputabnormal outputtedvalue

Outputted value needs to be fine tuned.

​

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.

RS485 Unable to receive response.

Communication parameter set-up mismatch

​

Address conflict

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

RS485 signal is unstable.

Poor wiring

Abnormal calendar battery

Calendar battery is low.

Other abnormalities

​

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 go to to turn on the function.

Please adjust output current value by set-up parameter .

Please confirm the correction of set-up parameter .

Please confirm the correction of set-up parameter .

Please refer to the to confirm the wiring is correct.

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

Please use to reset to default settings.

Please initialize the paddle wheel with .
