5 AB6484 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 Set the effective sliding range of the potentiometer as: r R r UP 0 00% R: Effective sliding range r : Residual resistance at 0 % side r : Residual resistance at 00% side As the left figure shows, set the 0 % and 00 % points to make the residual resistances of the potentiometer be r = r. Zero adjustment: Set the potentiometer sliding position at the 0 % point as shown in the figure above, and connect to the. 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 00 % point as shown in the figure above. Under this condition, turn the SPAN potentiometer adjustment knob until the output is set to 0 ma. Potentiometer knob for SPAN adjustment Potentiometer knob for ZERO adjustment ZERO adjustment range: 0 to 0 % FS SPAN adjustment range: 0 to00 % FS (Reconfirm point zero and repeat the procedure and to ensure the s accuracy.) Figure 4. Front panel of the POT/I Monitor switch setup Monitor switch is set by turning the front thumbwheel switches with a driver. Output is for high alarm and Output is for low alarm. Monitor LED turns on when the relay coil is excited. Output is excited when Input > Setpoint, and Output is excited when Input < Setpoint.

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 (0 to 0 %). 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 (0.0 to 0 %). 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 00 %, and low limit is 0 %.

Front panel of the limiter Ratio bias setup How to set the ratio: Switch the ratio/bias selector to the RATIO side. The ratio/bias display shows the ratio (0.0 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 to00 %). 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.
