■
Installation location
Avoid mounting this device in places characterized by any of the following:
• Temperature below -10 °C or above 60 °C (However, if the operating tempera-
ture and humidity ranges for the batteries are more narrow than the ranges for
the
MCF
, the ranges for the battery have priority.)
• Humidity exceeding 90 % RH
• Sudden changes in temperature, or condensation
• Corrosive or flammable gases
• Heavy concentration of conductive substances (e.g. dust, salt or iron dust), water
droplets, oil mist or organic solvents
• Vibration or shock
• Direct sunlight
• Splashing by water or rain
• Splashing by fluids (e.g. oil, chemicals)
• Constant, heavy splashing by water or dust
• Strong magnetic or electrical fields

Excessive flow rate
If the flow rate exceeds the maximum display range, alarm code
AL40
is displayed
alternately with the flow rate. Be sure to use the device within the flow rate range
stated in the specifications.
WARNING
Never allow gases that are within explosive limits to pass through this device. Doing so could
result in an explosion.
Do not use this device for oxygen gas. Doing so could result in a serious accident.
CAUTION
Be sure to use this device within the flow rate range stated in the specifications. To prevent
excessive flow, use a suitable means to control the supply pressure or use a throttle valve or
the like to control the flow rate.
If damage could result from the abnormal functioning of this device, include appropriate
redundancy in the system design.
If there is a risk of a power surge caused by lightning, use Azbil Corporation's SurgeNon to
prevent possible fire or equipment failure.
