Operation
1. Turn on the power switch in orde of slave, then master.
2. After all power is turned on, wait approximately 2 seconds before operating.
3. The HX-S-G2 power supply whose M/B CONTROL Connector IN is not connected to another HX-S-G2 Series
power supply is the Master unit (#1 in the previous page).
4. After the POWER switch has been turned ON, the output voltage will be displayed on the Master unit’s Number
Display (voltage) and the model name and the total power capacity will be displayed on the Master unit's Number
Display (current).
If there is discrepancy in total power capacity (the total power capacity of this time is different from that of the
previous time), the error code "E011" is displayed on the Number Display (voltage) and detected total power
capacity blinks in the bottom. After checking the total power capacity, hold down the "FUNC" key for more than 2
seconds and approve the detected number of devices to change to the measurement display mode.
5. The voltage measurement is displayed on the Number Display (voltage) of the master, and the current
measurement is displayed on the Number Display (current) of the master.
Total current value is displayed in the bottom Number Display.
Select power display with the "Display" key to display total power values.
Slaves, when operating normally, will display bars as
shown on the right.

2. Error Displays for Slave Units
In the event an alarm is triggered by a Slave while the Master is functioning normally;

The Sla
ve that detected the alarm will display the error code on the Number Display (voltage) and the alarm
type on the Number Display (current).

Error code "E006" is displayed on the Number Display (voltage) of the Master unit.
(When alarm is triggered by a Slave and Master is functioning normally)
