●A place where the ambient temperature may reach beyond the range of from 0 to 50°C while in operation.
●A place with rapid temperature changes, leading to dew condensation
●A place where corrosive gases (sulfide gas and ammonia gas, in particular) or combustible gases are emitted.
●A place with vibration or shock directly. (Vibration and shock may cause output relay malfunction.)
●A place exposed to water, oil, chemicals, steam and/or vapor.
(If the equipment gets wet, there is a risk of electric shock or fire, so have it inspected by the distributor.)
●A place where the unit is exposed to dust, salt air, or air containing iron particles.
●A place where the unit is subject to interference with static electricity, magnetism, and noise.
●A place where the unit is exposed to direct sunlight.
●A place where the heat may be accumulated due to the radiation of heat. Recommended site condition:
●A place where the ambient humidity during operation is between 45 to 85%RH.
About EMC standard
●This equipment is designed as Class A (for industrial environment). Do not use this equipment in home environment, or it may cause electric jamming. If you use this equipment in home environment, install appropriate measures on the outside of the equipment.
●Under the requirement of EMC standard, the maximum length of a sensor to be connected to this equipment is 30 m. Do not connect the sensor longer than 30 m.
Caution on installation on panel
●Attach the included Fixtures (2 pieces) onto the top and bottom of PXF5/9 , and tighten them with a screwdriver. The clamp torque is approx. 0.15 N·m (1.5 kg·cm) The plastic fixture is designed such that over tightening will cause left/right cracking to the central area of the Fixtures and hence reduce the torque. Cracking to the central area will not cause any problems in terms of usability of the equipment as is.
(However, do exercise caution in not applying too much torque because the casing is made of plastic.)
● The front of this equipment is waterproof in compliance with NEMA-4X standards (IP66-equivalent). However, regarding waterproofing between the equipment and the panel, use the included packing to ensure waterproofing and attach it according to the guidelines below. (Incorrect attachment may cause the equipment to lose its waterproof capabilities.)
(1)As shown in Fig. 1, insert the panel after attaching the packing to the equipment case.
(2)As shown in Fig. 2, tighten the fixture screws so that no gaps can remain between the equipment face, the packing and the panels. Once finished, confirm that there are no changes in shape such as displaced or improperly-fitted packing, etc. as shown in Fig. 3.
●Please exercise caution if the panel strength is weak and gaps develop between the packing and the panel, as this will result in the loss of its waterproofing capabilities.

Mounting on vertical plane (in horizontal position)
PXF5/9
Mounting on vertical plane (in horizontal position)
●In order not to hamper heat radiation, do not block the sides of the equipment.
●Do not block the air vents on the upper part of the terminal.
●For PXF9, please attach the Fixtures to the attachment holes in the center of the main unit.
Cautions on wiring
●For thermocouple input, use the designated compensation lead; for resistance temperature sensors, use wires with small lead wire resistance and without any resistance difference among the three wires.
●To avoid noise conductor effects, do not use input signal wires in close proximity with electric power lines or load lines.
●Use the input signal lines and output signal lines that are separated from each other and are shielded.
●If there is a lot of noise from the power source, adding an insulation transducer and using a noise filter is recommended. Always attach a noise filter to a panel that is grounded securely, and keep the wiring between the noise filter output side and the measuring equipment power terminal wiring to a minimum length. Please do not attach fuses and switches, etc. to the noise filter output wiring since doing so will decrease the filter’s effectiveness.
●Twisting the measuring instrument wiring is effective when connecting the wires. (The shorter the pitch of the twist, the more effective the connection is against noise.)
●When the power is turned on, it takes some time before a contact output starts operation. If using it as a signal to an external interlock circuit, please couple it with a delayed relay.
Concerning the output relay, connecting the maximum rated load will shorten the relay’s life; so please attach an auxiliary relay. If the output operation frequency is high, selecting a SSR drive output type is recommended. [Proportional cycles] Relay output: 30 seconds or more, SSR drive output: 1 second or more

●The alarm function does not work properly when an error takes place unless the settings are made correctly. Always verify its setting before operation.
●If the input wiring breaks, the display will read "UUUU" or "LLLL". When replacing the sensor, always turn the power OFF.
Others
●Do not wipe the equipment with organic solvents such as alcohol or benzene, etc. If wiping is necessary, use a neutral cleaning agent.
●Do not use mobile phones near the instrument (within 50 cm). Otherwise malfunction may occur.
●Trouble may occur if the equipment is used near a radio, TV, or wireless device.
●Do not turn off the power right after you change the setting. If you turn off the power after setting change, be sure to wait for a few seconds before turning it off, so that the changed values can be stored on the nonvolatile memory.
