Safety Instructions
The Flow Sensor have in after referred to as flow sensor and this manual contain essential information for the protection of users and others from possible injury and property damage and to ensure correct handling.
Please check that you fully understand the definition of the following messages (signs) before going on to read the text, and always follow the instructions.
These instructions must be followed while in maintenance ; Turn off the power supply, stop the supplied air, exhaust the residual pressure and verify the release of air before performing maintenance.
Otherwise it can cause injury.
Perform proper functional checks and leak tests after maintenance.
Stop operation when an abnormality is observed such that the flow sensor does not work properly or there is a leakage of fluid. Safety is not be assured due to unexpected malfunction. When leakage occurred from other parts except piping, the flow sensor might break. Cut off power supply and stop supplying pressure. Don’t apply pressure at leaking condition.
Precaution on Handling
Use UL approved product for direct current power supply.
1.Clamping voltage current circuit complies with UL508 Circuit which power supply if insulation transducer satisfying following conditions
Max. voltage (No load) : 30Vrms (42.4V peak) or less
Max. current : (1) | 8A or less (Including short circuit) | ||
(2) | When limited by the circuit | ||
