SETTING

If key-protect has been set, make sure to release key-
protect before operating the keys. (Please refer to    KEY-
PROTECT FUNCTION 
for the procedure.)

The conditions which are set are stored in an EEPROM.
Kindly note that the EEPROM has a life span and its
guaranteed life is 100,000 write operation cycles.

Setting of pressure values

[Set Value 1 (P1)] and [Set Value 2 (P2)] of the comparative

and [Set Value 3 (P3)] are set.

• 

The sensor returns to sensing mode after
Set Value 1 (P1) and Set Value 2 (P2)
have been set.

• 

Since the values which have been set are
stored in an EEPROM, they are not
erased even if the power supply is
switched off.

MODE

The setting of Set Value 2 (P2) with respect to Set Value 1
(P1) can only be towards the high pressure side in case of
the positive pressure type sensor and only towards the high
vacuum side in case of the vacuum pressure type sensor.

Set Value 1 (P1) and Set Value 2 (P2) can be made common
for all the output modes. However, when a changeover is
made to the automatic sensitivity setting mode, since Set
Value 3 (P3) has not been set, make sure to carry out the
pressure value settings for the automatic sensitivity mode.

The setting of Set Value 2 (P2) with respect to Set Value 1
(P1) can only be towards the high pressure side in case of
the positive pressure type sensor and only towards the high
vacuum side in case of the vacuum pressure type sensor.

Set Value 3 (P3) is automatically set to the mid-value of Set
Value 1 (P1) and Set Value 2 (P2). However, if Set Value 1
(P1) is set to a value on the vacuum pressure side for a
positive pressure type sensor or to the positive pressure side
for a vacuum pressure type sensor, Set Value 3 (P3) is
automatically set to the mid-value of ‘zero’(atmospheric
pressure) and Set Value 2 (P2). Further, if both, Set Value 1
(P1) and Set Value 2 (P2) are set to a value on the vacuum
pressure side for a positive pressure type sensor or to the
positive pressure side for a vacuum pressure type sensor, Set
Value 3 (P3) is automatically set to ‘zero’(atmospheric
pressure).

The automatically set Set Value 3 (P3) can be changed manually.

Since display of error messages is not possible during
pressure value setting in the automatic sensitivity setting
mode, make sure that the sensor is used within the rated
pressure range.
