Azbil MCW400A100 User manual

Thank you for purchasing the MCW400A100.
This manual contains information for ensuring
correct use of the MCW400A100. It also provides
necessary information for installation, maintenance,
and troubleshooting.
This manual should be read by those who design
and maintain devices that use the MCW400A100.
Be sure to keep this manual nearby for handy
reference.
Please read the "Terms and Conditions" from the
following URL before ordering or use:

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.

MOUNTING
• Use the MCW400A100 within the operating ranges
given in the specifications for temperature, humidity,
voltage, vibration, shock, mounting direction, atmos-
phere, etc. Failure to do so might cause fire or mal-
function.
• Do not allow lead clippings, chips or water to enter
the controller case. They might cause fire or faulty
operation.
CAUTION
CAUTION
Cautions are indicated when mishandling this
product might result in minor injury to the
user, or only physical damage to this product.

■Panel mounting procedure
(1) Insert the mounting part into the panel hole to firmly
fix it to the panel.
(2)
Insert the main unit into the back of the mounting part.
(3) After completing step (2), insert the mounting retain-
er from the back so that it engages the groove of the
mounting part.
Note
•To take the MCW400A100 off the panel, first
remove the mounting retainer with a screwdriver,
and then disassemble in the reverse order of
assembly.
■Connector and wiring
Handling Precautions
•Do not apply excessive force, vibration, or
impact to the connectors or cables. Doing so
might cause equipment failure.
•When using a switching regulator for the
power supply, be sure to ground the frame
ground.
•When using any device (switching regulator,
inverter motor, etc.) that produces electrical
noise near the flow sensor, be sure to ground
the frame ground of the device.
●Flow sensor connector and wires
Note
•Lead wire for trigger signal for memorizing
reference flow value must be supplied by the
customer. Wire size is 0.14 to 0.3mm2and outside
diameter of the insulator is 0.8 to 1.0mm.
●I/O connector and wires
●Connecting the cable of the flow sensor
The cable of the flow sensor is not yet connected to
the connector (pin contacts). Follow the steps below
to connect the cable and connector.
Handling Precautions
•Make sure that the connector cover (lead wire
insertion part) stands above the connector
main body as shown in the figure below. If the
connector cover is not lifted off the connector
main body, it cannot be used.
(1) Cut the cable to the required length. Remove the
sheath approx. 50mm from the end to free the lead
wires. However, do not remove the insulation from
the lead wires.
Handling Precautions
•The insulation at the end of the flow sensor
wire is incised at the factory. Cut off this por-
tion of the wire before inserting the leads into
the connector.
(2) Insert the lead wires into the holes in the connector
cover so that the lead wire colors and pin Nos. match
those indicated on the connector. Check through the
top of the semitransparent cover that the lead wires
are fully inserted to the end. (The insertion length is
approx. 9mm.)
Handling Precautions
•Ifreference flow value is desired, be sure to
insert that lead wire into the connector cover
before crimping.

(3) Carefully squeeze the cover and connector main
body together with an appropriate hand tool, such as
pliers so that no lead wires are disconnected from the
connector.
The crimping force must be 980.7N or less.
When the connector and cover top surfaces are level,
the connection work is complete.
●Connecting and disconnecting the cable
(1) To connect the flow sensor cable and signal cable,
position the lock levers as shown in the figure above,
and insert the cable connectors until the locks are
engaged.
(2) To disconnect the cable, push down the lock lever
sufficiently, hold the connector, and pull the cable
out. Be especially careful that no excessive force is
applied to the lead wires.
■ Internal circuit and external wiring example
■Operating
When the power is turned ON, this unit automatically
enters indication mode. In indication mode, the flow rate
of channel 1 is shown on the flow rate indicator and
channel indicator 1 is lit. The indicated channel can be
changed with the or key.
■Setting
Handling Precautions
•Do not press the keys with a mechanical pen-
cil or other sharp-tipped object. Doing so
might cause damage.
When the mode key is pressed after the power has been
turned ON, the mode enters the setting mode. To change
the settings from the factory defaults, follow the steps
below.

Handling Precautions
•
The displayed channel can be changed during hold.
•If the power is turned OFF, the peak hold or
bottom hold is cancelled.
•Peak hold and bottom hold cannot be done at
the same time.
•When the indication hold function is activated,
the output hold function is also activated at the
same time.

Handling Precautions
•If the threshold flow rate is set such that L1 ≤
L2, the switch output does not turn ON.
•“L1 ≤L2” may also come about when ∆L is
set in window comparator mode 2 or 3, due to
reading of the reference value, with the result
that the switch output does not turn ON.

■Operation mode
●Window comparator mode 1
L1 and L2 can be set to desired levels. If the flow rate
is increasing, SW output is not turned ON.
●Window comparator mode 2
L1 is automatically set according to the ∆L setting
and reference flow value (L1 = "reference flow
value" - ∆L). If the flow value is increasing, output
is not turned ON.
●Window comparator mode 3
L1 is automatically set according to the ∆L setting
and reference flow value (L1 = "reference flow
value" - ∆L).
Handling Precautions
•Do not input a trigger signal for memorizing
reference flow value frequently in window
comparator mode 2 or 3. Doing so might
cause the number of EEPROM erase-write
cycles to exceed the guaranteed amount.
●Window comparator mode 4
L1 and L2 can be set to desired levels.
●Hardware requirement
PC: PC-98 series or equivalent DOS/V machine
OS: Windows 95 or later
