Installation
Model RYY792X converters are mounted on panels. Install according to the following instructions:
Precautions for installation
Do not use the product in an atmosphere containing excessive humidity, acidic gases, or corrosive substances.
Use the product under the conditions specified in this document.
Use dedicated sockets.
Installation procedure
1) Mount the socket on the panel with DIN rail or screws. For screw-mounting, mounting screws (M4 15 or longer) are
additionally required. Mounting dimensions are shown in Figs. 1 and 2.
Before mounting the socket, make sure that it is in upright position. (Do not mount it upside down.)
2) Connect the wires to the terminals according to Wires Connection section.
Then, assemble the main unit with the socket by carefully inserting the main unit in the front of the socket. Improper
insertion (e.g., with the main unit inclined/upside down) can damage the pins of the main unit or the socket.
After insertion, finger-tighten the main unit fixing screw.

Adjustment
Precautions for making adjustment
IMPORTANT:
This product is adjusted before shipment. Do not turn the potentiometer knobs with paint locks.
When adjusting the potentiometer knobs on the front of the unit, use the appropriate size driver. Do not turn the
potentiometer knobs beyond their limits.
Use standard lead wires to be connected to the monitor terminal.
Do not touch components other than the potentiometer knobs and the setting switches when making adjustments.
Adjusting the POT/I converter
Set the effective sliding range of the potentiometer as:
Zero adjustment:
Set the potentiometer sliding position at the 0 % point as shown in the figure above, and connect to the converter. Then, turn the
ZERO potentiometer adjustment knob until the output is set to 4 mA.
Span adjustment:
Similarly, shift the potentiometer sliding position to the 100 % point as shown in the figure above. Under this condition, turn the
SPAN potentiometer adjustment knob until the output is set to 20 mA.
Figure 4. Front panel of the POT/I converter
Monitor switch setup
Monitor switch is set by turning the front thumbwheel switches with a driver. Output 1 is for high alarm and Output 2 is for low
alarm. Monitor LED turns on when the relay coil is excited.
Output 1 is excited when Input > Setpoint, and Output 2 is excited when Input < Setpoint.
Figure 5. Alarm trip operation Figure 6. Front panel of the monitor switch
Limiter setup
How to set high limit:
Switch the high/low limit selector to the upper side. The high/low limit display shows the high limit (-10 to +105 %). Press
UP/DOWN control for the value setup. The polarity indicator LED glows RED when the set value is in positive range, and glows
GREEN in negative range.
How to set low limit:
Switch the high/low limit selector to the downside. The high/low limit display shows the low limit (-10.0 to +105 %). Press
UP/DOWN control for the value setup. The polarity indicator LED glows RED when the set value is in positive range, and glows
GREEN in negative range.
The factory preset setting values for high limit is 100 %, and low limit is 0 %.

Ratio bias setup
How to set the ratio:
Switch the ratio/bias selector to the “RATIO” side. The ratio/bias display shows the ratio (0.10 to 4.00). Press UP/DOWN control
for the value setup.
The polarity indicator LED glows RED when the set value is in the positive gradient characteristic, and glows GREEN in the
negative gradient characteristic.
How to set the bias:
Switch the ratio/bias selector to the “BIAS” side.
The ratio/bias display shows the bias (0 to100 %). Press UP/DOWN control for the value setup. The polarity indicator LED
glows RED when the set value is positive, and glows GREEN when negative.
Figure 8. Front panel of the ratio bias
Equation:
Y = KX + B (positive gradient characteristic)
Y = KX +B + F (negative gradient characteristic)
where Y = Output signal (%)
K = Ratio (Linear characteristics, positive gradient: 0.1 to 4.00 / negative gradient: -0.1 to -4.00)
X = Input signal (approx.-10 to +120 %)
B = Bias (-100 to +100 %)
F = 100%
Fine adjustment:
Follow the procedure below for fine adjustment.
1) Under the equation: Xo = KX + B (positive gradient) or Xo = KX + B + F (negative gradient), shift the input signal value Xi to
zero point side and adjust the output Y to the result with ZERO adjustment.
2) Shift the input signal value X to the span point side and adjust the output Y to the result with SPAN adjustment.
3) Shift again the input signal value X to zero point side and check the output Y on the zero point side.
4) If the output Y is changed, repeat the procedure 1 through 3 again for adjustment.
The unit is set and calibrated for shipment as: Ratio (K)=1, Bias (B)=0%
