Verify the specifications before use.
Do not operate in an atmosphere containing flammable or explosive gases.
Fire or an explosion can result.
This product is not designed to be explosion proof.
Do not use the product in a place where static electricity is a problem.
Otherwise it can cause failure or malfunction of the system.
If using the product in an interlocking circuit:
•Provide a double interlocking system, for example a mechanical system.
•Check the product regularly for proper operation.
Otherwise malfunction can result, causing an accident.
The following instructions must be followed during maintenance :
•Turn off the power supply
•Stop the air supply, exhaust the residual pressure and verify that the air is released before performing
maintenance work
Otherwise an injury can result.
Caution
Do not touch the terminals and connectors while the power is on.
Otherwise electric shock, malfunction or damage to the product can result.
After maintenance is complete, perform appropriate functional inspections and leak tests.
Stop operation if the equipment does not function properly or there is a leakage of fluid.
NOTE
The direct current power supply used should be UL approved as follows.
Circuit (of class 2) which is of maximum 30Vrms (42.4 V peak), with UL 1310
class 2 power supply unit or UL 1585 class 2 transformer.
The product is a approved product only if it has a mark on the body.
Maintenance
How to reset the product after a power cut forcible de-energizing
The setting of the product will be retained as it was before a power cut or de-energizing.
The output condition is also basically recovered to that before a power cut or de-energizing,
but may change depending on the operating environment.
Therefore, check the safety of the whole installation before operating the product.

Mounting and Installation
Installation
Panel mounting
•Fix the panel mount adapter to the product with the mounting screws (nominal size:
3 x 8 L, 2 pcs.) supplied.
•The monitor can be mounted on a panel with a thickness of 0.5 to 6.0 mm.
Bracket mounting
•Mount the bracket using the mounting screws (M3 x 5 L) supplied.
•The required tightening torque is 0.5 to 0.7 Nm.
•Install the product (with bracket) using the M4 screws (2 pcs.).
•Bracket thickness is approximately 1.6 mm.
Refer to the product catalogue or SMC website (URL http://www.smcworld.com) for more
information about panel cut-out and mounting hole dimensions.

Wiring
Wiring of connector
•Connections should only be made with the power supply turned off.
•Use separate routes for the product wiring and any power or high voltage wiring.
Otherwise, malfunction may result due to noise.
•Ensure that the FG terminal is connected to ground when using a commercially
available switch-mode power supply. When a switch-mode power supply is connected
to the product, switching noise will be superimposed and the product specification can
no longer be met. This can be prevented by inserting a noise filter, such as a line noise
filter and ferrite core, between the switch-mode power supply and the product, or by
using a series power supply instead of a switch-mode power supply.
Attaching the connector to the sensor wire
Cover more than 20 mm
•Strip the sensor wire as shown.
•Do not cut the insulator.
•Insert the corresponding wire colour shown in the table into the
pin number printed on the sensor connector, to the bottom.
Pin no. Wire colour A
1 Brown (DC+)
2 NC
3 Blue (DC−)
4 Black (IN (1 to 5 V))
•Check that the above preparation has been performed
correctly, then part A shown should be pressed in by hand to make temporary connection.
•Part A should then be pressed in using a suitable tool, such as pliers.
•The sensor connector cannot be re-used once it has been fully crimped.
In cases of connection failure such as incorrect order of wires or incomplete insertion,
please use a new connector.
•If the sensor is not connected correctly "LLL" or "HHH" will be displayed.
Connecting / Disconnecting
•When mounting the connector, insert it
straight into the socket, holding the
lever and connector body, and push the

connector until the lever hooks into the
housing, and locks.
•When removing the connector, press
down the lever to release the hook from
the housing and pull the connector
straight out.

Flow Setting
Measurement mode
The mode in which the flow is detected
and displayed, and the switch function is
operating. This is the basic operating
mode; other modes should be selected for
set-point and other Function Setting changes.
: The display will indicate [LLL] if a sensor is not connected.
To use the product for flow rate indication, select the connected flow sensor using
function [F95] before setting any other functions.
Switch operation
When the flow (or voltage) falls below the set
value by the amount of hysteresis or more, the
switch will turn ON.
When the flow (or voltage) exceeds the set value,
the switch will turn OFF.
If this condition, shown to the right, is acceptable,
then keep these settings.
