Magmeter Operation Preparation - Toshiba LF622 Quick Start Manual

A. Magmeter Operation Preparation
NOTE: CHECK THE OPERATION MANUAL FOR SAFETY AND STORAGE
PRECAUTIONS BEFORE INSTALLATION!!
System check
- Check the wiring between the detector and the converter
- Check the wiring between converter and related instruments
- Make sure all the bolts of the connection flanges on which the flow meter is mounted
is securely tightened
- Make sure the direction of flow arrow is in accordance with actual flow
- Make sure flow meter is grounded with 100 ohm or less ground resistance.
- Make sure converter housing covers are securely tightened
Place system on-stream
- Let the fluid go through the detector pipe. When the detector is filled with the fluid,
stop the fluid and keep it still in the detector pipe and prepare to do a meter zero.
Power supply
- Make sure the power supply is as specified.
Checking converter parameters
- Check the configuration parameter settings (refer to instruction manual)
Zero Adjustment
- Warm up flow meter for 30 minutes. Make sure the fluid holds still in the detector
pipe, then start the zero adjustment (refer to instruction manual). Be sure to hold the
enter button for more than 3 sec until you see "Adjust Ready", then push enter one
more time.
On-line Measurement
- After checking the items and conducting the zero adjustment as listed above, let the
fluid go through the detector pipe. Output(4-20 mA dc) directly proportional to the
flow rate should be obtained.
