How to Operate
5-1. Preparation for start-up
Before supplying power, read and understand the following precautions. Ignoring these precautions may
cause an electric shock or damage the detector.
•
Connect the detector to a grounding circuit.
•
Check that the wiring is connected to external device properly.
•
Check that the power supply voltage is compliant with the specifications.
•
Because the external contact may be activated during the adjustment, take measures to prevent an
activated contact from having influences on external device.
•
Check that there is no clogging or leak in the connected tube. (If the connected tube is clogged, pressure
is applied to the sensor, causing errors and malfunctions.)
•
Check that the filter is attached properly. (The filter is specified based on the gas to be detected.)
5-2. Basic operating procedures
Normally, the detection mode is used for normal operations. (The detection mode is activated after the
power is turned on.)
The detector is restarted
after recovering from fault.
