- 2 -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 directcontact 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 andmalfunction.
• When wiring, use a crimping pliers and a solderless terminal with an insulation sleevein which an M3 screw fits.
• 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 does not have a built-in power switch, circuit breaker and fuse. It isnecessary 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.
• 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 orcleaning.
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 a hard 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 thefront 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 thesocket 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 SGF into the socket.
④ Fasten the mounting screw by turning it clockwise, to secure the SGF 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 thefront panel.
③ Insert a flat blade screwdriver into the Lock lever (lower part of the socket), andremove the socket from the DIN rail while pulling the lever down.

Manual Mode
If MANUAL is selected in [Auto/Manual] in Instrument setting mode, and if the DOWN
key is pressed for 3 seconds, then the unit can enter Manual mode.
The output frequency can be selected by the UP or DOWN key.
By pressing the SET key in Manual mode, or after Manual mode auto return time has
elapsed, the unit returns to the Default Display.

7.1 Indication after Power-on
After the power is turned on, the instrument is switched to warm-up status for 3
seconds. Multi-Display A indicates a model name, and Multi-Display B indicatesthe input code, Output 1 code and Output 2 code as follows.
The thousands and hundreds digits: Input code
The tens digit: Output 1 code
The ones digit. Output 2 code(e.g.) SGFW-F0OO-0-0
Multi-Display A:
Multi-Display B:
7.2 Operation
After warm-up, the unit proceeds to display mode.
The input type selected in [Frequency range group] will be converted to the pulses
set in Output 1 setting mode and Output 2 setting mode.
7.3 Indication Time
After preset indication time has elapsed, Multi-Display A, Multi-Display B andeach action indicator are turned OFF.
They light up again if any key is pressed.
They remain lit during setting mode or in the event of an input error.
If the indication time is set to 00:00, they remain lit.
7.4 Division Ratio
By setting Output 1 and Output 2 division values, obtains the division ratio(of the input value) for Output 1 and Output 2 (for SGFW only).
.
Division ratio is obtained by the following formula.

7.5 One-shot Output Pulse Width
If input pulses are entered, the output pulses will be output with the time set in [Output
1 one-shot output pulse width] or [Output 2 one-shot output pulse width].
However, if one-shot output pulse width is set to 0 (zero), this function will be disabled,
and the pulse width of input and output will be the same.
Pulse width accuracy: If input pulse width is 1 ms, and if one-shot output pulse width isset to 0 (zero), the difference between input pulse width andoutput pulse width is less than 10 μs.

Operation
Problem

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

No output

Possible Cause

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 oforder.
Check whether input andoutput wires are securely
connected to the I/O
terminals of the instrument.
Check whether the wiring of
input and output are correct.
Selections in [Output 1
Normal/Reverse (p.20)] or[Output 2 Normal/Reverse(p.21)] may be incorrect.

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