Handling Precautions
• Do not disassemble the MCW400A100. Doing
so might cause faulty operation.
•
Do not use
the MCW400A100
during the tran-
sitional period (0.5s) immediately after the
power has been turned ON.
The MCW400A100 is
a multi-channel display designed to
remotely display the instantaneous flow rate of up to four
MCS-series flow sensors. It also produces open collector
output for any flow that is within the specified limits.
Additionally, by means of RS-232C communications, a per-
sonal computer can be used to change settings or to view and
save flow-rate indications and outputs.
■ Display and console
■ Connector
■ Location
Install the MCW400A100 where:
• There are no ignitable or flammable materials.
• It is not exposed to direct sunlight (ultraviolet rays).
• There are no salt particles or iron particles, and no
excessive dust.
• Humidity is not excessive.
• There are no organic solvents, phosphate ester
hydraulic fluid, sulfur dioxide, chlorine gas, and/or acids.
•
It is far from high voltage sources, welding machines,
and other sources of electrical noise.
