however, the Pinnacle unit responds to the first limit value that impacts output.

Description
Enables or disables a voltage lower limit
value for the process (8-bit value):
• 0 = disable
• non-zero value = enable
Read back this value with Command 163.
Sets a minimum process voltage. With
this limit in place, the Pinnacle unit waits
for the output voltage to first exceed the
limit. Once that happens, output will
remain on until you turn off the output or
until the voltage falls below the
established limit. If the voltage falls
below the limit, output will turn off and
error message E010 will appear on the
display. With this command, send 2 data
bytes (16-bit value). Read back this value
with Command 177.
Sets a maximum limit for output power.
Accuracy is +0.3% of the full rated
output power for the supply. Send 2 data
bytes (16-bit value); value must be
between 0 and the maximum rated output
power for the supply in kilowatts.
Assume 3 decimals for a stand-alone unit
(20000 = 20.000 kW or 20000 watts) and
2 decimals for a master/slave unit (2000
= 20.00 kW or 20000 watts).
Note: Master/slave units will refresh to
the maximum limit for power on
power up, after explicit slave
faults, or after connecting or
disconnecting slaves.
Read back this value with Command 141.
