Blow the air to flush out the foreign matters, dust and
etc. before installing the pipe. Uncleaned air may cause
malfunction or damage to the product.
When mounting the fitting, a wrench should be used
on the metal part.
Using on other parts of the product with a wrench may
damage the product.
If the tightening torque is exceeded, the product can
be broken.
If the tightening torque is insufficient, the fitting may
become loose and cause air leakage.
After installation completed, turn on the gas and
power supply for proper operation and leaking test to
confirme whether the installation is correct.
Caution
5.4 Electrical Connection
NOTE
Incorrect power supply
Destruction of the integrated electronics
4
Operate the product using a power supply unit with protected extra-low voltage
(PELV).
4
The system must incorporate safe electrical cut-off of the power supply in compliance
with EN60204.
4
Do not connect or disconnect the connector under tension and/or when voltage is ap-
plied.
NOTE
Connect with the power turned on
Damage to the electronics and/or malfunction
4
Switch off the power supply before connecting cables!
The folw sensor is supplied with a 6-wire connection cable with open cable ends.
Integrate the folw sensor into your application in accordance with the electrical circuit diagram. The fol-
lowing points must be taken into account for this:
•
Check wire color and terminal number when wiring. Incorrect wiring can cause permanent damages
to the sensor, check wire color and terminal number against the manual before wiring.
•
Avoid repeatedly bending or stretching the lead wire. It can cause damage to the sheath, or break-
age of the wire.
•
Confirm wiring insulation. Please avoid poor insulations (and interference from another circuit, poor
insulation between terminals, etc.) it can lead to over current being applied to the product, causing
damage.
•
Do not route wires and cables together with power or high voltage cables. The product may mal-
function due to interference or noise and surge voltage from power and high voltage cables.
•
Do not short-circuit the load. When the load is short-circuited, an error will be displayed. But excess
current may cause damage to the sensor.
