AC Module Remote Programming ReFlex Power™ Programming Manual
M380056-03 Rev L 103
Command
Description
:RANGe?
Query the voltage range of the unit.
:PROTection<NRf>
Sets the Over -Voltage Protection setpoint.
:PROTection?
Returns the Over Voltage Protection setpoint.
:UPSET
4
<NRf>,<NRf>,
<NRf>,<NRf>
The UPSET Event has four arguments that allow surge/sag or dropouts to be
programmed to start at a specific phase delay, to a specified RMS voltage
level, for specified time, and then apply an after event voltage level.
:UPSET?
4
Returns the above UPSET Event parameters if the event has not finished.
The returned duration value will be zero when the event is complete.
:UNDERVOLTage
:PROTection[<NRf>]
Sets the Under Voltage Protection setpoint.
:PROTection?
Returns the Under Voltage Protection setpoint.
:TRIPped?
Query whether Under Voltage Protection supervisory tripped or not
:STATe <bool>
Sets or clears the global detect enable for the Under Voltage Protection
supervisory. 0 = disable, 1 = enable
:STATe?
Query the global detect enable for the Under Voltage Protection supervisory.
0 = disabled, 1 = enabled
:MODE
:SHUTdown<bool>
Set or clear the shutdown enable for Under Voltage Protection supervisory
:SHUTdown?
Query the shutdown enable for Under Voltage Protection supervisory
1
See Section 4.12 for examples for using Group operation.

PHASE:LEAD specifies that the specified PHASE <NRf> angle value is the number of
degrees that the rising waveform zero cross will occur before the Phase Reference in time
.
Cleared by *RST, by command, or Power cycle. Power on default is LAG.
2
PHASE:LAG specifies that the specified PHASE <NRf> angle value is the number of
degrees that the rising waveform zero cross will occur after the Phase Reference in time.
Cleared by *RST, by command, or Power cycle. Power on default is LAG.
The Phase Reference is a timing signal that is generated by the Phase Master Module. It is
used by the Phase Master and Slave Modules to offset their own rising zero cross waveform
timing from the Phase Reference time marker. The PHASE setpoint accepts values
between -360.0 and +360.0 degrees, this will interact with LEAD/LAG.

Prior to setting the Voltage above 125V in the low range or above 250V in the high range, you
must set the three Current related setpoints, SOURce<n>:CURRent, SOURce<n>:CURRent
:PROTection and SOURce<n>:INRushcurr:PROTection, else a “parameter out of range”
error will occur. The reason is that these three Current setpoints are designed to limit the
maximum continuous power to 875VA, and have the protection values at safe levels; therefore,
they must be lowered in order to raise the voltage above the values stated for the low range or
for the high range. The three Current setpoint formulae in order, are as follows:
Step 1: Current Setpoint (I
set
) as a function of voltage:
Low Range formula: I
set
(v) = I
set
(max) * 125 / V
set
, for V
set
> 125
Example: to set the voltage to 137V. I
set
(137) = 7.14 * 125/137 = 6.514A(max)
SOUR<n>:CURR 6.51
