3.2 Indications at Power-on and Initialization
When the power switch is set to ON, the internal circuitry is automatically checked, and this product
becomes ready for operation if no abnormality is detected. On the panel, the values set with the DIP
switch are set. For the initial setting of the DIP switch, refer to "
3.6 Setting at Power-on
".
If this product cannot be operated after the power is turned on, a fault has occurred. Turn off the power
immediately and then contact NF Corporation or its representative.
For fault diagnosis at Power-on, refer to "
5.1.1 Errors at Power-on ".
All LEDs above the switches, the 0% LED of output meter LEDs, the overload LED (OVLD), and the
error LED (ERR) turn on. After all LEDs above the switches turn off and the error LED (ERR) blink for a
few seconds, the overload LED (OVLD) and the error LED (ERR) turn off. Next, when the internal power
supply is fixed, the state selected at power-on time is set.
3.3 I/O Terminals
3.3.1 Input connector: A (front)/B (rear)
Signal input connectors are provided. Select A or B with the corresponding input signal selection switches
(INPUT A/INPUT B). The LED of the selected input will light. If both of the A and B switches are
pressed, both signals are added. However, the maximum input voltage is within ±10 V for the sum of the
2 inputs.
