Connect the piping to the pressure switch with a plug or fitting.
The tightening torque of the piping port must be 8.8 Nm or less.
Spanner
Wiring
Connection
Connections should only be made with the power supply turned off.
Incorrect wiring will lead to digital pressure switch breakdown, failure or
malfunction. So be sure to confirm the wire colour and terminal number
before wiring.

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.

: •Hysteresis mode (same as for positive pressure use) When the value of hysteresis is set to 2 digits or less,
the switching output might chatter due to fluctuation of the input pressure around its set point.
•Window comparator mode (same as for positive pressure use) since the hysteresis will be 3 digits, separate
P1 from P2 (in case of 2-output type, same as for P3 and P4) by 7 digits or more.
: 1 digit is the minimum pressure display unit.

Failure predictive count: Normal Once Twice 3 times
The failure predictive detection counter is incremented when the switch is
turned on then is turned off, without the pressure (exceeding P1) not reaching
the failure predictive pressure (P3).
The failure predictive detection output is energized when the set failure
predictive counter (EC) is incremented consecutively. When the switch is
turned ON and the pressure (exceeding P1) exceeds the failure predictive
pressure (P3), the failure predictive counter is reset.
(This example shows a case in the hysteresis mode.)
Other Settings
Peak hold mode
Pressing the button when pressure is displayed enables the
upper limit peak value (value with a high degree of vacuum) to be
held. In this case, "H" is displayed on the LCD. To reset holding,
press the button again.
Bottom hold mode
Pressing the button when pressure is displayed enables the
lower limit peak value (value with low vacuum) to be held. In this
case "d" is displayed on the LCD. To reset holding, press the
button again.
Reset function
Pressing the RESET button causes the following
1. Measurement mode
•Zero clear
•Clearing the peak hold mode or bottom hold mode
•Clearing the failure predictive function internal counter
•Resetting the failure predictive output
2. Upon error occurrence
•The data set in the setting mode is retained as is and the state when the
power supply was turned on is restored (System reset is triggered).
•In case of a data error, the setting mode is selected. When you finish
setting, the state when the power supply was turned on is restored.
(System reset is triggered).
: In the set value input mode, the reset function does not work.
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
