CAUTION
When making the pipe connections, hold the hexagonal part of the connector
section and turn the pipe to tighten. After connecting, check that there are no
gas leaks.
If using Rc connections, take care not to coat with too much sealant.
Foreign matter or burrs in the pipes may also cause measurement errors.
Do not apply a negative voltage or a voltage exceeding 5 V to the external setup
voltage input terminal. Doing so might cause malfunction or equipment failure.
When using a relay for external contact input and/or external 3-way switching
input, always use a relay designed for micro-current use (with gold contacts).
Failure to do so could cause faulty contact, resulting in malfunction.
If there is a risk of a power surge caused by lightning, use Azbil Corporation’s
SurgeNon to prevent possible fire or equipment failure.
Gas type switching by external contact input, flow rate switching, and analog
input/output voltage range switching by external 3-way input switching should
be done only after setting the operation mode to fully closed. Switching while
controlling could cause large fluctuations.
Be sure to check that the wiring is correct before turning the power on.
Incorrect wiring could cause damage or malfunction.
Do not apply excessive force to cables or connectors when connector cables or the
AC adapter is attached. Excessive force may damage the connectors or circuit board.
Do not operate the console keys using a sharp object such as a mechanical pencil or
screwdriver. Doing so might damage the console.
When discarding the device, dispose of it as industrial waste, following local
regulations.
