CONNECTION OF PRESSURE SENSOR HEAD
Make sure that the power supply is OFF while connecting or removing the pres-
sure sensor head
DPH-100
series (optional).
This product can automatically recognize the connected pressure sensor head.
When the pressure sensor head is replaced, the threshold value and the zero-
adjustment value change. Therefore, set those values again.
How to connect
Insert the connector of the pressure sensor head
DPH-100
series (optional) into the connector area
for the pressure sensor head of this product.

How to disconnect
Pressing the release lever attached to the connec-
tor of the pressure sensor head, pull out the con-
nector.

CONTROLLER CASCADING
Make sure that the power supply is OFF while adding or removing the series
connection type.
In case 2 or more the series connection types are connected in cascade, make
sure to mount them on a DIN rail.

When connecting 2 or more in cascade, use the sub cable for the second series
connection type onwards.

How to cascade
1.
Mount the controllers, one by one, on the
DIN rail.
2.
Slide the controllers next to each other,
and connect the quick-connection ca-
bles.

OUTPUT MODE AND OUTPUT OPERATION
The EASY mode, window comparator mode, hysteresis mode, forced ON output
mode, or forced OFF output mode can be selected individually as the comparative
output mode 1 or the comparative output 2.
However, the comparative output 2 cannot be set to the window comparator
mode.
For details, refer to “
12
OUTPUT MODE
.”
EASY mode
The comparative output ON / OFF state can be controlled in this mode.

H: Hysteresis (Note)
In case of compound pressure type or positive pres-
sure type, hysteresis is set to the lower pressure side.
In case of vacuum pressure type, hyster-
esis is set to the lower vacuum side.
Note: Hysteresis can be set to “
” (1% F.S.), “
” (2% F.S.) or “
” (5% F.S.).
For setting method, refer to
<PRO 1: Hysteresis setting>
in “

Window comparator mode
In this mode, the ON or OFF state of the comparative output is controlled with a
pressure in the set range.
H: Hysteresis (Note 1)
In case of compound pressure type or positive pres-
sure type, hysteresis is set to the lower pressure side.
In case of vacuum pressure type, hyster-
esis is set to the lower vacuum side.
