1. Installation precautions

CautionThis instrument is intended to be used under the following environmental conditions(IEC61010-1): Overvoltage category , Pollution degree 2
Ensure the mounting location corresponds to the following conditions:• A minimum of dust, and an absence of corrosive gases• No flammable, explosive gases• No mechanical vibrations or shocks• No exposure to direct sunlight, an ambient temperature of -5 to 55 (23 to 131 )that does not change rapidly, and no icing• An ambient non-condensing humidity of 35 to 85%RH• No large capacity electromagnetic switches or cables through which large current is flowing• No water, oil or chemicals or where the vapors of these substances can come into
direct contact with the unit
• When installing this unit within a control panel, take note that ambient temperature ofthis unit must not exceed 55 (131 ). Otherwise the life of electronic components(especially electrolytic capacitor) may be shortened.
Note: Avoid setting this instrument directly on or near flammable material even though
the case of this instrument is made of flame-resistant resin.

2. Wiring precautions

Caution• Do not leave wire remnants in the instrument, because they could cause a fire or a malfunction.
• When wiring terminals, use ferrules with an insulation sleeve and crimping pliers madeby Phoenix Contact GMBH & CO. applicable to terminals.
• Tighten the terminal screw using the specified torque. If excessive force is applied tothe screw when tightening, the screw or case may be damaged.
• This instrument has no built-in power switch, circuit breaker or fuse. It is necessary to
install them near the instrument.
(Recommended fuse: Time-lag fuse, rated voltage 250V AC, rated current 2A)• For wiring of AC power source, be sure to use exclusive terminals as described in thismanual. If AC power source is connected to incorrect terminals, the unit will burn out.
• For a 24V DC power source, do not confuse polarity when wiring.
• For DC voltage and current inputs, do not confuse polarity when wiring.
• Do not apply a commercial power source to the sensor which is connected to the input
terminal nor allow the power source to come into contact with the sensor.
• Keep the input/output wires and power line separate.

3. Operation and maintenance precautions

Caution• Do not touch live terminals. This may cause electric shock or problems in operation.
• Turn the power supply to the instrument OFF when retightening the terminal andcleaning. Working or touching the terminal with the power switched ON may result insevere injury or death due to Electric Shock.
• Use a soft, dry cloth when cleaning the instrument.
(Alcohol based substances may tarnish or deface the unit.)• As the display section is vulnerable, do not strike or scratch it with a hard object orpress hard on it.

(Fig. 8.2-1)• Indication when input value is -2000 or less
For the indication of -2000 or less (up to –10% output), the input value and the minus (-)
sign are indicated alternately.

IN• Indication when input value is 10000 or more
For the indication of 10000 or more (up to 110% output), the lower 4 digits of input value
are flashing.
(e.g.) Indication of 10020

Flashes.
• Underrange, Overrange and Sensor burnout alarm indication
Even if any selection is made during the Display selection, the following indications appear.
Underrange : "" flashes on the Input display.
Overrange : "" flashes on the Input display.
• Indication time setting
If indication time is set, the displays will go off after the indication time has elapsed.
(Only the power indicator is lit.)
If power is turned on again, or if any of the keys,,
and the Sub-mode key
is pressed while displays are unlit, the displays will light again.
8.2.1 When using this unit as a standard ratio transmitter
Set the filter time constant to 0.0 seconds, andset the Output Normal/Reverse selection to “Normal”.
8.2.2 When using the Reverse function
This function reverses the output (100 to 0%)
Input
that corresponds to the input (0 to 100%).
Set the Output Normal/Reverse selection to “Reverse”.
8.2.3 When using the first order lag filter function
The value is outputted by performing the firstorder lag computation using the filter time
constant “T”. (Fig. 8.2.3-1)
Set the filter time constant to a random value(0.0 to 10.0 seconds).

Attached function• Power failure countermeasure:
The setting data is backed up in the non-volatile IC memory.
• Self-diagnosis:
The CPU is monitored by a watchdog timer, and if an abnormal status is foundon the CPU, the unit is switched to warm-up status with all outputs off.

No output

Presumed cause and solution• “Lock” has been selected during Set value lock selection.
Select “Unlock”.
Presumed cause and solution• The sensor may be out of order. Change the sensor.
• Check whether input and output wires are securely
connected to the Input/Output terminals of the instrument.
Ensure that input and output wires are securely connectedto the Input/Output terminals.
• Check whether the wiring of input and output is correct.
• Check whether Output 100% and Output 0% value havebeen set to suitable values.
• Check whether Output type and Output Normal/Reverse havebeen selected correctly during Output type and Output
Normal/Reverse selection.
