SMC Networks ISE35 Operation Manual
Operation
When the pressure exceeds the set value,
the Pressure switch will turn ON. When the
pressure falls below the set value by the
amount of hysteresis or more, the
Pressure switch will turn OFF. As a default
setting, the Pressure switch is set to turn
ON when the pressure exceeds 0.35 MPa,
and turn OFF when it is below 0.34 MPa.
If this condition,
shown to the right, is
acceptable, then keep
t
hese settings.
<How to perform>
1. Press the button in the measurement mode to display set values.
2. Press the or button to change the set value.
The button is to increase and the button is to decrease.
Press the button once to increase by one digit, and press it continuously
to keep increasing the set value.
Press the button once to decrease by one digit, and press it continuously
to keep decreasing the set value.
3. Press the button to complete the setting.
Wiring
Connection
Connections should only be made with the power supply turned off.
Use separate routes for the Pressure switch 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
b
e 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 the switch-mode power supply.
Connector
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.
Digital Pressure Switch
Operation Manual
ISE35
The Pressure switch operates within a set pressure range during window
comparator mode. Set P_L, P_L (switch lower limit) and P_H, P_H (switch upper
limit) with the setting procedure above.
Indication LED (green): Displays the switch condition.
3-digit LED:
Displays the current status of pressure, setting mode and error code.
Four display modes can be selected: display always in red or green,
or display changing from green to red, or red to green, according to
the output status.
button (UP): Selects the mode or increases the ON/OFF set value.
Press this button to change to the peak display mode.
button (DOWN): Selects the mode or decreases the ON/OFF set value.
Press this button to change to the bottom display mode.
button (SET): Press this button to change to another mode and to set a value.

Safety Instructions
These safety instructions are intended to prevent hazardous situations and/or
equipment damage.
T
hese instructions indicate the level of potential hazard with the labels of
"Caution", "Warning" or "Danger". They are all important notes for safety and must
be followed in addition to International standards (ISO/IEC) and other safety
r
egulations.
CAUTION indicates a hazard with a low level of risk
which, if not avoided, could result in minor or
moderate injury.
Operator
T
his operation manual is intended for those who have knowledge of machinery
using pneumatic equipment, and have sufficient knowledge of assembly,
operation and maintenance of such equipment. Only those persons are
allowed to perform assembly, operation and maintenance.
Read and understand this operation manual carefully before assembling,
operating or providing maintenance to the product.
Caution:
Warning:
Danger:
WARNING indicates a hazard with a medium level of
risk which, if not avoided, could result in death or
serious injury.
DANGER indicates a hazard with a high level of risk
which, if not avoided, will result in death or serious
injury.

Maintenance
How to reset the product after a power cut or 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. If
the installation is using accurate control, wait until the product has warmed up
(approximately 20 to 30 minutes).
