• SMTEMP# Clear Probe Alarm: Clears an SM Temp Probe Fail alarm. The only selection is Clear. Once Clear is selected
and confirmed, the alarm clears.
• SMDUE1 Temp #: Sets temperature port # on the SMDUE1 module to None, Battery, or Ambient. When set, the following
parameters can also be set. Note that one or more analog inputs on SMDUE1 needs to be configured for temperature ports
(Advance Settings Menu / Custom Inputs Tab / SMDUE #).
SMDUE1 Temp# High 2: Sets temperature port # on the SMDUE1 module “Temperature High 2” alarm point.
SMDUE1 Temp# High 1: Sets temperature port # on the SMDUE1 module “Temperature High 1” alarm point.
SMDUE1 Temp# Low: Sets temperature port # on the SMDUE1 module “Temperature Low” alarm point.
• SMDUE2 Temp #: Sets temperature port # on the SMDUE2 module to None, Battery, or Ambient. When set, the following
parameters can also be set. Note that one or more analog inputs on SMDUE2 needs to be configured for temperature ports
(Advance Settings Menu / Custom Inputs Tab / SMDUE #).
SMDUE2 Temp# High 2: Sets temperature port # on the SMDUE2 module “Temperature High 2” alarm point.
SMDUE2 Temp# High 1: Sets temperature port # on the SMDUE2 module “Temperature High 1” alarm point.
SMDUE2 Temp# Low: Sets temperature port # on the SMDUE2 module “Temperature Low” alarm point.
Rectifiers Tab Programmable Parameter Descriptions
• Current Limit: Enables or disables adjusting the output current limit point. When enabled, the following parameters can be
set.
NOTE! By default this is set to disabled. When disabled, rectifier current limit is set in the rectifier (not via the NCU) at the
maximum current limit point.
Current Limit Point: Sets the output current limit point for all rectifiers combined when the “Current Limit” setting above is
set to enabled.
• HVSD Limit: Sets the High Voltage Shutdown point for all rectifiers.
• Restart on HVSD: Enables or disables the High Voltage Shutdown Restart feature for all rectifiers.
• HVSD Restart Time: When the High Voltage Shutdown Restart feature is enabled and the output exceeds the high voltage
limit, the rectifiers restart after this time period expires.
• Walk-In: Enables or disables the start-up walk-in feature for all rectifiers. When enabled, the following parameters can be
set.
Walk- In Time: Sets the start-up walk-in time when the “Walk-In” setting above is set to enabled.
• Sequence Start Interval: Sets the sequence start interval (time period between starting each rectifier in the system).
• Nominal AC Voltage: Enter the nominal line to neutral voltage (signal phase rectifier) or nominal line to line voltage (three
phase rectifier).
• Mains Failure Alarm Limit 1: Sets the Mains Failure Alarm 1 value (percent of nominal).
• Mains Failure Alarm Limit 2: Sets the Mains Failure Alarm 2 value (percent of nominal).
Corresponding Alarms:
- Phase A Voltage Low 1 (Nominal Minus "Mains Failure Alarm 1” Percent of Nominal)
