⑥⑦ Power supply voltage
Check to see if the I/O voltage of the power supply module and the voltage of the
external power supply are within allowable limits of specifications. Too low or high a
power supply voltage may cause the system to malfunction.
Power supply module specifications are as follows:
Input voltage regulation --- LQV000: 85 to 132 VAC
Output voltage regulation --- 5 VDC ± 5%
Determine the output voltage of the power supply module from the voltage measured at
the SERVICE CHECK terminals shown below.
(For the operating power supply voltage of each module and the voltage of the external
power supply, see the manual supplied with the module.)
LQV000
POWER
AC100-120V
Even if the input voltage of the power supply module falls within a specified
range, assume it to be in an input power abnormality when it is close to the
upper or lower limit of the range, and call upon the power supply facility
manager for a checkup.
Hot swapping of modules can lead to hardware or software destruction. Be
sure to replace the module with the power off.
LQV100: 85 to 132 VAC, 85 to 132 VDC
LQV020: 20.4 to 28.8 VDC
LQV200: 170 to 264 VAC
