Precautions for Safe Use
1.
Precautions for the environment
•
Use and preserve within the proper temperature and humidity
described in the specifications.
•
Temperature of surroundings for preservation (including during
transportation) and use:
-
10 to 55
C, humidity: 45 to 85%.
•
Do not install, among others, near heat devices such as coils or
other devices having coils, etc.
•
Avoid preserving (including during transportation) and using in a
humid place, in a corrosive gas environment, outdoors and in a
place which receives direct sunlight.
•
Preserve and use without exposing to danger of explosion, flamma-
ble dust, gas and vapor, excessive dust, and saline spray or drop-
lets.
•
Avoid preserving (including during transportation) and using in a
place which is vulnerable to flooding or oil spillage.
•
Avoid preserving (including during transportation) and using in a
place where vibrations and impacts are strong. Similarly, avoid
using next to a high-capacity contactor which may impacts at oper-
ation. Doing so causes malfunctions such as chattering, etc.
•
Do not install the product near devices generating strong high-fre-
quency waves or surges. When using a noise filter, check the volt-
age and current and install it as close to the product as possible.
2.
Cautions for Use
•
Read the instruction manual and catalog before operating and
maintaining the product.
•
Fit socket(s) and DIN rail(s) so that the screws are tight.
If the screws are not tight, DIN rail(s), socket(s), the product and
cable(s) may lead to come off.
•
Be sure to fit socket(s) to DIN rail(s) without fail.
•
Use metal strengthener(s) to maintain a firm connection between
the product and socket(s).
•
Read the instructions manual and catalog before the operation and
maintenance of the product.
•
When fitting crimping terminal(s) to terminal screw(s), use a tight-
ening torque of between 0.45 and 0.6 N·m
•
Use power supply of appropriate specifications to provide control
source(s), inputs, etc., and to wire cables.
[Recommended cable to wire between the model 61F and elec-
trode(s) when using three-core cabtire cable(s) of completely insu-
lated 600 V 0.75 mm VCT: 50 m max.]
•
Do not put power line(s), high-voltage cable(s) and wire(s) of elec-
trode circuit(s) in the same duct nor wire closely. Doing so causes
malfunctions by getting vulnerable to induction noise.
•
Shorten the distance for wiring between the model 61F and elec-
trode holders as much as possible. Long distance for wiring may
causes malfunctions because stray capacitance may influence
operation, or abnormal surges or noise may run through electrode
circuit(s).
•
Be sure to ground common electrode terminal(s). Doing so can
reduce some effects of noise.
•
Use the product within the noted supply voltage and rated load.
•
Before using, recheck the application, wiring, power supply, etc.
•
Check the application and power supply.
Power supply (AC 220 V, AC 230 V) consists of other specifications.
If the power voltage is not AC 200 V or AC 100 V, follow the instruc-
tions described on the device.
•
Firmly ground the earth terminal No.4.
•
Make sure that electrode probes in the liquid do not come in con-
tact one another as it may cause malfunction. Use separator when
connecting.
•
Tighten nuts for electrode probe(s) firmly.
•
Prevent flotage from attaching to electrode.
•
This device is not available when the resistance is too high and is
not conductive such as oil.
Do not touch the terminals while power is being supplied.
Doing so may possibly result in electric shock. Make sure
that the terminal cover is installed before using the
product.
Do not attempt to disassemble, repair, or modify the
product. Doing so may occasionally result in minor or
moderate injury due to electric shock.
