CAUTION

!This is a Class A instrument. In a domestic environment, this instrument may cause radio interference, in which case the user may be required to take adequate measures.

!This instrument is protected from electric shock by reinforced insulation. Provide reinforced insulation between the wire for the input signal and the wires for instrument power supply, source of power and loads.

!Be sure to provide an appropriate surge control circuit respectively for the following:

-If input/output or signal lines within the building are longer than 30 meters.

-If input/output or signal lines leave the building, regardless the length.

!This instrument is designed for installation in an enclosed instrumentation panel. All highvoltage connections such as power supply terminals must be enclosed in the instrumentation panel to avoid electric shock by operating personnel.

!All precautions described in this manual should be taken to avoid damage to the instrument or equipment.

!All wiring must be in accordance with local codes and regulations.

!All wiring must be completed before power is turned on to prevent electric shock, instrument failure, or incorrect action.

The power must be turned off before repairing work for input break and output failure including replacement of sensor, contactor or SSR, and all wiring must be completed before power is turned on again.

!To prevent instrument damage or failure, protect the power line and the input/output lines from high currents with a protection device such as fuse, circuit breaker, etc.

!Prevent metal fragments or lead wire scraps from falling inside instrument case to avoid electric shock, fire or malfunction.

!Tighten each terminal screw to the specified torque found in the manual to avoid electric shock, fire or malfunction.

!For proper operation of this instrument, provide adequate ventilation for heat dispensation.

!Do not connect wires to unused terminals as this will interfere with proper operation of the instrument.

!Turn off the power supply before cleaning the instrument.

!Do not use a volatile solvent such as paint thinner to clean the instrument. Deformation or discoloration will occur. Use a soft, dry cloth to remove stains from the instrument.

!To avoid damage to instrument display, do not rub with an abrasive material or push front panel with a hard object.

!Do not connect modular connectors to telephone line.

If set to the STOP state (dSTP) by the contact input, no parameters in Engineering mode can be changed. They can be changed in case of the following.

•The instrument changed the STOP state (KSTP) by the key operation.

•The instrument changed the STOP state by both the key operation and contact input operation.

For the RUN/STOP transfer, see the Instruction Manual (IMR01H01-E#)

2.Press the <R/S key while pressing the SET key with the PV/SV monitor mode change the instrument to setup setting mode.

For the setup setting mode, see Instruction Manual (IMR01H01-E#).

2. DETAILS OF PARAMETER SETTING

2.1 Attention Items in Setting

If any of the following parameter is changed, the relevant set value is initialized or is automatically converted.

Before changing the set values, always record all of them (SV setting & CT monitor mode, setup setting mode, parameter setting mode and engineering mode).

After changing the set values, always check all of them (SV setting & CT monitor mode, setup setting mode, parameter setting mode and engineering mode).

!"When changed parameter of input type selection or engineering unit setting

When change a input type and unit, all the set value of a list shown below is initialized. Set it in value to use once again.

2. DETAILS OF PARAMETER SETTING

!"When changed parameter of decimal point position setting

When change a decimal point position, it is converted into about set value of a list shown below automatically. However, the set value may change as a result of changing the position of the decimal point. Therefore in that case, re-set it to the value to be used.

Example and caution of automatic conversion

•Decimal point location moves in accordance with it when increases decimal point location. Example: When the position of the decimal point changed from 0 to 1 with SLH set to 800 ° C.

(Changed from 800 to 800.0)

(SLH)		(SLH)

•If the setting range is not between − 1999 and + 9999 regardless of the position of the decimal point, it is limited by the range from − 1999 to + 9999.

Example: Suppose set SLH is 1372 ° C, if change decimal point position from 0 to 1.

SLH becomes 999.9 as it exceeds the setting range.
