Wiring

For thermocouple input, use the designated compensation lead; for RTD input, use wires with small lead wire
●
resistance and without any resistance difference among the three wires.
To avoid noise conductor effects, input signal wires should be separated from electric power lines or load lines.
●
Input signal wire and output signal wire should be separated each other. And both should be shield wire.
●
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; otherwise the filter's effectiveness will be
decreased.
Twisting the power wires is effective when connecting the wires. (The shorter the pitch of the twist, the more
●
effective the connection is against noise.)
Operation preparation time is required for the contact output when power is turned on. 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 product's life; so please attach
an auxiliary relay. If the output operation frequency is high, selecting a SSR drive output type is recommended.
[Proportionate cycles] Relay output: 30 seconds or more, SSR drive output:
1 second or more
When inductive loads such as magnetic opening/closing equipment, etc. as relay output equipment are connected,
●
use of a surge absorber is recommended in order to protect the contacts against opening/closing surges and to
ensure long-term use.
Recommended specification for the surge absorber

Attachment position: between the relay control output contacts.

Operation

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

Please 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 this equipment (within 50 cm). Otherwise a malfunction may result.
●
Trouble may occur if the equipment is used near a radio, TV, or wireless device.
●
This equipment should be treated as an industrial waste when it is disposed of.
