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 -10 to 55 (14 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 the vapors of these substances can come into direct contact
with the unit.
• When installing this unit within a control panel, please note that ambient temperature ofthis unit – not the ambient temperature of the control panel – 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.

Wiring Precautions

Caution• Do not leave wire remnants in the instrument, as they could cause a fire and malfunction.
• When wiring, use a crimping pliers and a solderless terminal with an insulation sleeve in whichan M3 screw fits.
• 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 does not have a built-in power switch, circuit breaker and fuse. It is necessary
to install a power switch, circuit breaker and fuse near the instrument.
(Recommended fuse: Time-lag fuse, rated voltage 250 V AC, rated current 2 A)
• For wiring of the AC power source, be sure to use terminals as described in this manual.
If the AC power source is connected to incorrect terminals, the unit will be burnt out.
• 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.
• When using DC voltage and current input, do not confuse polarity when wiring.
• Keep the input/output wires and power line separate.

Operation and Maintenance Precautions

Caution• Do not touch live terminals. This may cause an electrical shock or problems in operation.
• Turn the power supply to the instrument OFF when retightening the terminal or cleaning.
Working on or touching the terminal with the power switched ON may result in severe injury or
death due to electrical 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, be careful not to put pressure on, scratch or strike it with ahard object.

Mounting to, and Removal from the DIN Rail

Caution• Mount the DIN rail horizontally.
• To remove the socket, a flat blade screwdriver is required.
Never turn the screwdriver when inserting it into the Lock lever. If excessive power is applied
to the lever, it may break.
• If the instrument is mounted in a position susceptible to vibration or shock, mountcommercially available fastening plates at both ends of the instrument.

Mounting to the DIN rail (Fig. 3.2-1)① Separate the instrument from the socket by loosening the mounting screw on the front
panel.
② Make sure the lock lever of the socket is located in the lower part of the socket.
Hook the upper side of the socket onto the DIN rail, then fit the lower part of the socket
onto the DIN rail (A clicking sound should be heard when done properly).

Caution• Before inserting the instrument to the socket, make sure the cable is wired properly.
(Refer to “4. Wiring”.)• When inserting or removing the socket, make sure the socket is oriented vertically.
If force is applied in any other direction than vertically, a malfunction may occur.
• If the mounting screw is fastened too tightly, a malfunction may occur.
③ Insert the SGAL into the socket.
④ Fasten the mounting screw by turning it clockwise, to secure the SGAL onto the socket.
Tighten the screw lightly.
Removal from the DIN rail (Fig. 3.2-2)① Turn the power to the instrument OFF.
② Separate the instrument from the socket by loosening the mounting screw on the front panel.
③ Insert a flat blade screwdriver into the Lock lever (lower part of the socket), and remove thesocket from the DIN rail while pulling the lever down.

8.2.1
Basic Operation for Setting Alarm 1 to Alarm 4 Value
Alarm 1 value to Alarm 4 value can be set in Simple setting mode.
These setting items are the same as those in Alarm 1 to Alarm 4 setting mode.
To enter Simple setting mode, follow the procedure below.
(e.g.) Any alarm type (except No alarm action) is selected in [Alarm 1 type] to [Alarm 4 type].
Default Display is RUN display mode 1.
① Press the DISP key.
The unit enters RUN display mode 2.
Multi-Display A indicates an input value, and Multi-Display B indicates Alarm 1 value.
② Press the SET key.
The unit enters Simple setting mode.
Multi-Display A indicates, and Multi-Display B flashes Alarm 1 value.
③ Set the alarm value with the SHIFT, UP, or DOWN key, and press the DISP key.
Alarm 1 value will be saved (registered), and the unit moves to [Alarm 2 value].
④ Set Alarm 2 to Alarm 4 value in the same manner.
⑤ Press the DISP key at [Alarm 4 value].
The unit reverts to RUN display mode 2.

8.3.2
Input Indication Range
The input value is displayed within the following range:[Indication value at input 0% – (Indication value at input 100% – Indication value at input 0%)
x 10%] to[Indication value at input 100% + (Indication value at input 100% – Indication value at input 0%)
x 10%]For a value lower than (and including) -2000, the minus (-) sign and the input value light up
alternately.
For a value higher than (and including) 10000, the lower 4 digits flash.
(The placement of the decimal point follows the selection.)
When input value exceeds the indication range:
flashes.
When input value drops below the indication range:
flashes.
8.3.3
Input Disconnection
If input is disconnected, the input status will become as follows.
Input
Input Status
4 to 20mA (Built-in 50
shunt resistor)
Equals 0 mA input.
4 to 20mA (Externally mounted 250
shunt resistor) Equals 0 mA input.
4 to 20mA (Externally mounted 50
shunt resistor) Equals 0 mA input.*
1 to 5V
Equals 0 V input.
If the indication is overscale, the Alarm indicator will light up, andwill flash.
* If the shunt resistor is out of order or disconnected, the indication will be overscale.
8.3.4
Indication Time Setting
After preset indication time has elapsed, Multi-Display A, Multi-Display B and each action
indicator are turned OFF.
They will light up again if any alarm is activated, or if any key is pressed.
They remain lit during a setting mode, when an alarm action is ON, or if input errors or input
disconnection occurs.
If the indication time is set to 00:00, they will remain lit.

Indication
Problem
Multi-Display A or B flashesor

when

Possible Cause
The sensor may bedisconnected.
Check whether the input
terminals of this instrument are
securely mounted to the sensor.
Check the input signal source.
Check whether sensor input
is correct.

will light up.
10.2

Key Operation
ProblemIf the DISP key is pressed,
Multi-Display A shows, and the display
mode cannot be switched.

10.3

Operation
Problem

When Multi-Display A or B
indicates an input value, theinput value does not change.

No alarm output

Possible Cause

Solution
Replace with a new sensor.
Connect the sensor terminals to
the instrument input terminals
securely.
Ensure that the input signal
source works normally.
Select the same sensor typeas that of currently used sensor.
Set it to a suitable value.
Use an ungrounded typesensor.
Keep the instrument clear ofany potentially disruptive
equipment.
To indicate continuously,
set the Indication Time (p.31) to“00 : 00”.

Solution

The DISP key is in locked status.

Press the DISP key for approx. 3
seconds to release the key lock.

Possible Cause
The sensor may be out of order.
Check whether input and output
wires are securely connected to
the I/O terminals of the
instrument.
Check whether the wiring of
input and output are correct.
Check whether Alarm 1 value
to Alarm 4 value are suitable.
(p.35)

Solution
Replace with the new sensor.
Ensure that input and output
wires are securely connected to
the I/O terminals of the
instrument.
Wire them correctly.
