OUTPUT CONTROL
The K3C has output according to the measurement value. The output can be used to control external devices, such as valves and absorption
systems.
To control an external device, a reference value must be set so that the output can be turned ON if the measurement value is above the refer-
ence value and turned OFF if the measurement value is below the reference value. (The ON/OFF setting can be reversed.)
The value turning the outputON is called the ON pointand the value turning the outputOFF is called the OFF point.The following is an example
of ON- and OFF-point settings on condition that the Controller has normally open output.

Automatic Compensation of Set Value for Original Pressure Fluctuation
When using the K3C-MP8-T1Z 4-channel model, the set values on channels 2 through 4 can be compensated according to the original
pressure fluctuation that is input to channel 1. When using the K3C-DP8-TIZ 2-channel model, the CH2 setting can be compensated.
Compensation value = Original pressure fluctuation (%) x compensation coefficient
Compensation is performed every minute by comparing the one-minute mean value and reference value of the original pressure.
The reference value is the mid-value between the ON- and OFF-points of OUT 1 on channel 1.
1. The compensation coefficient will appear by pressing the DISPLAY Key.
2. Select the channel for value compensation.
3. On the basis of no compensation as 0 times, change the compensation coefficient with the Up or Down Key within a range between 0
to 10 times.

1. Hold both ends of the female connector connected to the
Sensor I/O Connector so that the protrusion on the female
connector faces upward, orientate the hole in the male con-
nector on the Sensor upwards, and insert the female connec-
tor into the hole until the protrusion clicks in.
2. A lock cover is slid through the Sensor I/O Connector to pre-
vent it from coming free due to vibration or shock.
Insert the lock cover facing in the correct direction (a) as
shown in the following figure, and rotate it clockwise (b) until
it clicks in.

3. To unlock the connector, rotate the lock cover counterclock-
wise until it clicks, then pull it towards you.
To disconnect the connector, hold both ends of the connector,
then pull it towards you.

ends of the connector when disconnecting it.
E8M/E8MS
E8M/E8MS
E8MS-jj/E8M-10
The pressure-introducing section (aluminum for E8MS, SUS304
for E8M) is fixed with tapered 1/8 NPT male screws and M5
female screws.
When using tapered screws, use tapered 1/8 NPT female
screws. Wrap the tapered 1/8 NPT male screws with sealing tape
to prevent any leakage. Tighten the male screws to a torque no
more than 3.9 N S m (2.88 ft S lbs).
Tighten M5 female screws to a torque no more than 1 to 1.5
N S m (0.74 to 1.11 ft S lbs).
When tightening a screw, hold by its hexagonal head, not by its
body.
E8M-N0
The pressure-introducing section (SUS304) is fixed with M5 male
screws.
Tighten male screws to a torque no more than 1 to 1.5 N S m
(0.74 to 1.11 ft S lbs).
When tightening a male screw, hold by its hexagonal head, not
by its body.
E8M-A1
The pressure-introducing section (SUS303) is fixed with M5
female screws (7 mm deep).
Tighten screws for the pressure-introducing section to a torque
no more than 1 to 1.5 N S m (0.74 to 1.11 ft S lbs).
M4 female screws are used for the product mounting sections.
When mounting the product, tighten the screws while holding a
metal part of the product, not a resin part.
Tighten the product mounting screws to a torque no more than
1.2 N S m (0.89 ft S lbs).
If the positive pressure section is released and positive pressure
is applied to the negative pressure section, a positive pressure
may be displayed.
All Models
Do not use the Sensor in an environment subject to corrosive or
combustible gases.
Be sure to use the Sensor in an environment where air-borne
water or oil is removed by air filters.
Do not use the Sensor alongside a high-tension voltage line or
power line.
Do not expose the Sensor to water.
Mount the Sensor so that ultrasonic vibrations will not be applied
directly to the Sensor.
Be sure to use the Sensor under the rated pressure.
Do not insert any wire into the pressure sections. Doing so may
damage the pressure elements and cause a malfunction.
Do not apply any tensile strength in excess of 20N (4.5 lbs) for
E8MS, 30N (6.75 lbs) for E8M to the cables or connectors.
Do not pull the cables. When removing the connectors for
external connection, be sure to use the lock lever.
K3C
Install the Sensor horizontally.
The recommended panel thickness is 1 to 5 mm (0.04 to 0.20 in).
Do not install the Sensor in an environment subject to strong
vibration or shock.
Do not install the Sensor under dusty conditions.
Do not install the Sensor in an environment subject to corrosive
gases, particularly sulfide and ammonia gases.
