Caution
This 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 of
this unit must not exceed 55 (131 ). Otherwise the life of electronic components

2. .W Wi ir ri in ng gp pr re ec ca au ut ti io on ns s
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 made
by Phoenix Contact GMBH & CO. applicable to terminals.
• Tighten the terminal screw using the specified torque. If excessive force is applied to
the 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 this
manual. 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.

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 and
cleaning. Working or touching the terminal with the power switched ON may result in
severe 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 or
press hard on it.

8.2 Operation
The unit enters the Run mode as shown in (Fig. 8.2-1). The input signal selected during
Input type selection is converted to the output selected during Output type selection.
(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.
(e.g.) Indication of -2000 IN 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 IN
•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, and
set the Output Normal/Reverse selection to “Normal”.
8.2.2 When using the Reverse function
This function reverses the output (100 to 0%)
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 first
order 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).
Indicates the input value.
Indicates the output value in
a
percentage form (%).
Output value corresponding to the input value is indicated
in a percentage form (%).

Input display is flashing
" " or " ".
• The sensor may be burnt out.
Change each sensor.
• Check whether the sensor is securely connected to the input
terminals of the instrument.
Ensure that the sensor terminals are securely connected
to the input terminals of the instrument.
• Check the input signal source.
The indication of the Input
display is irregular or
unstable.
• Check whether the sensor correcting value is suitable.
Set it to a suitable value.
• There may be equipment that interferes with or makes
noise near the unit.
Keep equipment that interferes with or makes noise
away from the unit.
10.2 Key operation
Problem Presumed cause and solution
Setting or adjustment is
not possible.
• “Lock” has been selected during Set value lock selection.
Select “Unlock”.
10.3 Operation
Problem Presumed cause and solution
Input value does not
change.
• 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 connected
to the Input/Output terminals.
• Check whether the wiring of input and output is correct.
No output • Check whether Output 100% and Output 0% value have
been set to suitable values.
