Turn-On Check Procedure
WARNING
There is a potential electrical shock hazard when using a power system without output protection. Do
not turn ON power without output protection properly assembled. Turn OFF power system or
disconnect power system from AC mains before making or changing any rear panel connection.
WARNING
The doors (on both the left and the right side) must be in LOCK position at all times to prevent access
to hazardous parts and sections.
4.8.1
General
The following procedure ensures that the power system is operational and may be used as a basic
incoming inspection check. Refer to Figure 2-1 and Figure 2- for the location of the controls indicated in
the procedure. Please note that this procedure is valid for standard units. For blank units, all the
parameters settings and status reading can be made by using communication interfaces. Refer to the
User manual for further information.
4.8.2
Prior to Operation
1. Power On/Off switch at Off position.
2. Ensure that the protection of output terminals is mounted and properly assembled.
3. Connect the unit to an AC mains as described in Section 4.7.
4. Connect a DVM with appropriate cables for the rated voltage to the output terminals.
5. Turn the front panel Power switch to On.
6. Ensure that the power supply is configured to the default setting (refer to User Manual IA761-04-02_,
Parameter Setting Memory section).
7. When power system is turned ON and all LCD Display segments and LEDs illuminate momentarily,
then the LCD display shows:
”
OUT OFF
” (not applicable to Blank Panel master power supply).
8. The power system operating status is then displayed (not applicable to Blank Panel master power
supply).
4.8.3
Constant Voltage Check (Standard Master Power Supply)
1. Turn on the output by pressing OUT button so the OUT LED illuminates.
2. Observe the power system Voltage display and rotate the Voltage encoder.
3. Ensure that the output voltage varies while the Voltage encoder is rotated. The minimum control
range is from zero to the maximum rated output for the power system model.
4. Compare the DVM reading with the front panel Voltage display to verify the accuracy of the Voltage
display.
5. Ensure that the front panel CV indication on the LCD screen is active.
6. Turn off the front panel Power switch.
