• 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 bits of wire in the instrument, because 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.
• 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.

7. Adjustment
Performs the output zero and span adjustments.
For this instrument, the output adjustment has already been completed when shipped.
If the instrument is used with the ordered Input/Output spec, the adjustment is not required.
However, for calibration, or for the fine adjustment of the SGM to which any equipment isconnected, perform the adjustment.
Connect an mV generator or Dial resistor to the input terminals of this instrument.
Connect a digital multimeter to the output terminals.
7.1

Basic Operation of Adjustment

Use the following trimmers on the front panel for adjustment.
Output 1 Zero: Adjusts the value of Output 1 Zero.
Output 1 Span: Adjusts the value of Output 1 Span.
Output 2 Zero: Adjusts the value of Output 2 Zero. (for SGMW only)
Output 2 Span: Adjusts the value of Output 2 Span. (for SGMW only)
7.2

Adjustment
All adjustment items are shown below.
Perform adjustment as follows.

7.2.1 Output 1 Adjustment
The following outlines the procedure for Output 1 adjustment.
① Enter the value corresponding to output 0%, and adjust the value using the‘Output 1 Zero’ trimmer while viewing the output value (on the digital multimeter).
② Enter the value corresponding to output 100%, and adjust the value using the‘Output 1 Span’ trimmer while viewing the output value (on the digital multimeter).
③ Enter the value corresponding to output 0% again, and confirm the output value(on the digital multimeter).
④ If the value corresponding to output 0% is not at 0%, repeat steps ① to ③
again
7.2.2 Output 2 Adjustment
The procedure for Output 2 adjustment is the same as that of Output 1 adjustment.
Use Output 2 Zero and Span trimmers for adjustment.

8. Operation

8.1 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 and output code.
(e.g.) SGM-A01-0-0
Multi-Display A:
Multi-Display B:
A value corresponding to input 0% will be output for Output 1 and Output 2.
8.2 Operation
After warm-up status, the unit enters display mode.
The input signal will be converted to the output selected in [Output 1 type] and[Output 2 type].
8.2.1 Input Indication Range
The measured value is indicated within the following range:[Output 0% value – (Output 100% value – Output 0% value) ×10%] to[Output 100% value + (Output 100% value – Output 0% value) ×10%]
For a value lower than (and including) -2000, the input value and the minus (-) sign
are indicated alternately. For a value higher than (and including) 10000, the lower 4
digits will flash. (The placement of the decimal point follows the selection.)
When the measured value exceeds the indication range,
will flash.
When the measured value drops below the indication range,
will flash.
8.2.2 Indication Range of Output 1 and Output 2
The output value is indicated within the following range:[Indication value at output 0% – (Indication value at output 100% – Indication
value at output 0%)×10%] to[Indication value at output 100% + (Indication value at output 100% – Indication
value at output 0%)×10%]
However, the high limit value is 9999, and the low limit value is -1999. (Theplacement of the decimal point follows the selection.)
8.2.3 Input Disconnection Status
If input is disconnected, the input status will be equal to 0 mA input.
8.2.4 Indication Time Setting
After preset indication time has elapsed, Multi-Display A, Multi-Display B andeach action indicator are turned OFF.
They will light up again if any key is pressed.
They remain lit during setting mode, or in the event of an input error or input
disconnection.
If the indication time is set to 00:00, they will remain lit.
8.2.5 Square Root Function
Selects Enabled/Disabled of the square root extraction function.
(Factory default: Disabled)IN’ : Input after square root extraction'

IN = IN

IN : Input (0 to 100%)- 34 -

8.2.6 Low Level Cutoff Function
When PV input is near 0 (zero), the result of the square root extraction changes
considerably with only a very small change of input, which also affects the indication
value. This function prevents this effect.
If PV input is lower than the low level cutoff value, the PV is forced to become 0(zero).
The low level cutoff value is indicated in a percentage form (%) corresponding to
the input range.
8.2.7

Ratio and Bias Settings

Ratio setting
When ‘Ratio setting’ is selected in [Ratio setting method], the ratio and bias
value for the output value corresponding to the input value can be set.
Output 1 ratio setting
Sets the ratio for Output 1 output value.
The output will be produced by [(Input x Ratio) + Bias value] (for normal output)
based on the slope set in [Output 0% value] and [Output 100% value].
• Output 2 ratio setting
Sets the ratio for Output 2 output value.
The output will be produced by [(Input x Ratio) + Bias value] (for normal output)
based on the slope set in [Output 0% value] and [Output 100% value].
Output 1 bias setting
Sets the bias value for Output 1 output value.
The bias value is added to [Input x Ratio] to produce the output based on theslope set in [Output 0% value] and [Output 100% value].
Output 2 bias setting
Sets the bias value for Output 2 output value.
The bias value is added to [Input x Ratio] to produce the output based on theslope set in [Output 0% value] and [Output 100% value].

10. Troubleshooting
10.1 Indication
Problem
Multi-Display A or B
flashesor
wen it indicatesan input value.

Multi-Display A or B isirregular or unstable
when it indicates aninput value.

Displays and indicators
are unlit.
If any key is pressed,
they will light up.
10.2 Key Operation
ProblemIf the DISP key ispressed, Multi-Display A
shows, and thedisplay mode cannot beswitched.
10.3 Operation
Problem
When Multi-Display A or
B indicates an input
value, the input value
does not change.

No output

Possible Cause
The sensor may bedisconnected.
Check whether the sensor
is securely mounted to the
input terminals of this
instrument.
Check the input signal
source.
Sensor correction value is
unsuitable.
AC leaks into the sensor
circuit.
There may be equipmentthat interferes with or makes
noise near the instrument.
The Indication Time (p.28) is
set to any value other than
00 : 00.
(Factory default is 30 : 00.)

Solution
Replace with a new sensor.

Possible Cause
The DISP key is in locked
status.

Solution
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 wire 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 type(p.22)], [Output 1 Normal/
Reverse (p.23)], [Output 2
type (p.25)] or [Output 2
Normal/Reverse (p.26)]
may be incorrect.

Solution
Replace with the new sensor.

- 42 -

Connect the sensor terminals
to the instrument input
terminals securely.
Ensure that the input signal
source works normally.
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.28)
to “00 : 00”.

Ensure that input and output
wire are securely connectedto the I/O terminals of the
instrument.
Wire them correctly.
Make a correct selection in[Output 1 type (p.22)],[Output 1 Normal/Reverse(p.23)], [Output 2 type (p.25)]
or [Output 2 Normal/Reverse(p.26)].
