Handling Instructions and Precautions
Handling Instructions and Precautions
General precautions
1. When using a switching regulator obtained on the market for the
power supply, always ground the frame ground (F.G.) terminal.
2. When using equipment (switching regulator, inverter motor, etc.) that
can become a source of noise around the EP Sensor mounting area,
always ground the equipment frame ground (F.G.) terminal.
3. When wiring is completed, check that there are no errors in the wiring
connections.
Wiring
1. Check power supply fluctuations to ensure that power input does not
exceed the rated value.
2. Avoid use during the transient period (0.5s) when the power is
switched on.
3. Do not use needle tips or other sharp points to perform key operation.
Others
1. Zero calibration is a function for adjusting the reference electric
potential where the measured value is 0V. The 0V electric potential is
recorded at space where no metal plate or charged object is
connected to the ground.
2. When the power supply is connected and the operation mode is
switched between the ion balance monitor mode and averaged data
output mode, or between the ion balance monitor mode and actual
measured data output mode, the reference electric potential is
automatically set to the ground electric potential connected to the body.

1. Since miswiring in the EP Sensor, or in the power supply, switch, and
communication cable, can damage both the EP Monitor and EP
Sensor, always check the wiring before switching on the power.
2. The setting conditions are written to EEPROM and saved. Be aware
that EEPROM has a finite lifetime, with a write guarantee times up to
100,000 times.
1. For mounting the EP Sensor, use either the screws provided (M3×
0.5, length 18mm [0.709in.]) or M3×0.5 screws. Use a tightening
torque of 0.4N·m [3.5in·lbf]. Be careful when tightening, since over-
tightening will damage the EP Sensor.
2. Always perform grounding. Because measurement of electric
potential uses the ground electric potential as the reference, the
electric potential cannot be accurately measured unless connected to
a ground.
3. The EP Sensor body is connected to a ground. Be sure to provide
adequate insulation when mounting in a location subject to applying
voltages.
4. Do not touch the detecting portion. Also, do not let high pressure air
blow against it. The detecting portion could be damaged.
5. Ensure a dust-free environment around the detecting portion.
6. If the detecting portion requires cleaning, position the detecting
portion so that it faces downward, and blow air at a pressure of
0.1MPa [14.5psi] or less from a distance of at least 100mm [3.94in.].
7. Where stability in electric potential detection is needed, a wait of at
least 15 minutes after the power supply is switched on before starting
operation is recommended.
8. This sensor measures the strength of electric field to calculate the
voltage value. As a result, be aware that the presence of items
capable of disturbing the electric field (relays, solenoids, metal chips,
etc.) near the sensor, or between the sensor and the item being
measured, could affect the measurement value.

Connect the EP Sensor DTY-EPS and the mini clamp connector. Follow
the procedure below to perform the connections.
1. Check that the connector cover (the part where lead wire is inserted)
is protruding from the connector body.
It cannot be used if it’s flat and placed at the same level against the
body.
2. Arrange the EP Sensor cable into the required form.
Since the insulation on the tip of the lead wire has been peeled off
and soldered, cut the wires at about 10mm [0.39in.] from the tip so
that it does not protrude from the insulation.
3. Follow the instructions in the table to insert the lead wires into the
hole in the connector cover. Look through the top of the semi-
transparent cover to check that the lead wires have been firmly
inserted all the way to the back. (Insertion is about 9mm [0.35in.].)
Use caution in making the connections, since switching on the power
with mistakes in the connections will damage the EP Sensor and EP
Monitor.
4. Taking care to avoid letting the lead wire slip out from the connector,
use pliers or some other hand tool to crimp the cover and connector
body, and push the cover into the connector body.
Limit the crimping force to 980.7N [220lbf.] or less.
When the cover is flat and placed at the same level against the
connector body, the connection is complete.
5. Check one more time that the wiring is correct.
Sensor and connector connection procedure
To mount the EP Sensor and the power supply, switch, and
communication cable, align the lock lever position as shown in the figure,
and push until the lock hooks on the controller-side connector.
To remove, push down hard on the lock lever, take the connector and pull
it out. At this time, be careful to avoid applying unnecessary force on the
lead wires.
