Iout_OC_fault_limit (0x46): Sets the value at which the power
supply will shut down. The default OC_fault_limit is 68Adc at
high_line and 30A at low_line. (The value is contingent on
whether the power supply operates in the low_line or
high_line mode). This level can be permanently changed and
stored in non-volatile memory. Which level is changed is
contingent on the input voltage applied to the power supply
at the time the change takes place.
Iout_OC_fault_response (0x47): Sets the response if the
output overload exceeds the OC_Fault_limit value. The
default OC_fault_response is hiccup (0xF8). The only two
allowable states are latched (0xC0) or hiccup. The default
response state can be permanently changed and stored in
non-volatile memory. The response is the same for both
low_line and high_line operations.
Iout_OC_warn_limit (0x4A): Sets the value at which the
power supply issues a warning that the output current is
getting too close to the shutdown level. The default
OC_Warn_limit is set to 64.8A at high_line and 27.8A at
low_line. This level can be permanently changed and stored
in non-volatile memory. Which level is changed is contingent
on the input voltage applied to the power supply at the time
the change takes place.
OT_fault_limit (0x4F ): Sets the temperature value at which
the power supply shuts down. The default OT_fault_limit is
set at TBD°C. This level can be permanently changed and
stored in non-volatile memory.
OT_fault_response (0x50): Sets the response if the output
overtemperature exceeds the OT_Fault_limit value. The
default OT_fault_response is hiccup (0xC0). The only two
allowable states are latched (0x80) or hiccup. The default
response state can be permanently changed and stored in
non-volatile memory.
OT_warn_limit (0x51):
Sets the value at which the power
supply issues a warning that internal temperatures are
getting too close to the shutdown level. The default
OT_Warn_limit is set to TBD°C. This level can be permanently
changed and stored in non-volatile memory.
Vin_OV_fault_limit (0x55):
Sets the value at which the power
supply shuts down because the input voltage exceeds the
allowable operational limit. The default Vin_OV_fault_limit is
set at 300Vac. This level can be permanently lowered and
stored in non-volatile memory.
Vin_OV_fault_response (0x56):
Sets the response if the input
voltage level exceeds the Vin_OV_fault_limit value. The
default Vin_OV_fault_response is restart (0xC0). The only two
allowable states are latched (0x80) and restart (0xC0). The
default response state can be permanently changed and
stored in non-volatile memory.
Vin_UV_warn_limit (0x58): This is another warning flag
indicating that the input voltage is decreasing dangerously
close to the low input voltage shutdown level. The default
UV_fault_limit is 90Vac. This level can be permanently raised,
but not lowered, and stored in non-volatile memory.
Vin_UV_fault_limit (0x59):
Sets the value at which the power
supply shuts down because the input voltage falls below the
allowable operational limit. The default Vin_UV_fault_limit is
set at 85Vac. This level can be permanently raised and stored
in non-volatile memory
Vin_UV_fault_response (0x5A): Sets the response if the input
voltage level falls below the Vin_UV_fault_limit value. The
default Vin_UV_fault_response is restart (0xC0). The only two
allowable states are latched (0x80) and restart (0xC0). The
default response state can be permanently changed and
stored in non-volatile memory.
