3.8.13 Warning Screens
There are two warning screens that may appear during the course of
operation:
H ARD F AULT
Hard Fault warns that a hardware fault has occurred in a power module, such
as an overtemperature, undervoltage of AC input, or converter failure. These
conditions might clear themselves, however, if they continue to occur after
pressing the F4 (ClrFault) key, contact the factory for service assistance.
OVP F AULT
OVP Fault occurs when the output voltage of the supply exceeds the OVP
setting. When this occurs the output is disabled, and voltage and current
output go to 0. To clear the display, press F1 (Clr OVP). The display will
return to Home Menu Page 1, and the output will remain disabled.
Note:
It is important to correct the condition that caused the OVP, prior to
re-enabling the output.
3.9 Remote Analog Control Connector (J1)
The Analog Control connector of the Remote Analog Interface on the rear
panel allows the unit to be configured for different operating configurations:
front panel (local) and remote programming of voltage, current, and OVP,
voltage and current monitoring, output enable/disable, etc. Refer to Figure
3-13 for the connector pin-out diagram. The setup and operating requirements
of each configuration are provided in Sections 3.10 through 3.13.3.
The SGI also has the capability of providing summing of remote analog input
with the set values on the front panel (or programmed values via the digital
interface) for voltage, current and OVP. This capability provides a means to
modulate a set value with the signal on the voltage, current and OVP analog
input. If the user only desires to control the unit with the analog input, all the
front panel values (V/I/OVP) or digital settings should be set to zero.
