Voltage Output Settings; Controlling The Output - Promax FA-405 Manual

P LIMIT Power limit
Press the "P LIMIT" key in the "LIMITS" field until the symbol "P-const"
flashes. The power limit can now be adjusted to 1 W steps by using the
encoder wheel. If the "P LIMIT" key is now pressed for longer than 2s,
the power upper limit will again be set at "200 W". To complete the
input, press the "ENTER" key. An inadvertently wrong-set limit setting
can be erased/reset with the " CE " key. As a result of this, the previous
set value will be indicated and the setting menu exited. The "P-const"
will no longer flash.
Attention: The current "I LIMIT" is adjusted independently of its

4.4.2 Voltage output settings

V SET Using the "V SET" key, the output voltage can be adjusted up to the
preset upper limit directly. For this the "V SET" key must be pressed
and held and the voltage changed with the encoder wheel. If the "fine"
F key is selected, the changes occur in 10 mV steps. If "norm" N key
is selected, the changes occur in 1V steps.
ENTER Each input via the "LIMITS" keypad is completed with the "ENTER"
key.
Any values incorrectly entered via the "LIMITS" keypad can be reset
CE
with the "CE" key.
F If the "N" key is pressed, the "fine" symbol disappears from the display.
If the "F" key is pressed, the symbol "fine" appears on the display.
LOCK Pressing the "LOCK" key locks/blocks all keys and the encoder wheel
against inadvertent adjustment. Only the "Power" switch remains active.
Locking is indicated by the "locked" symbol in the bottom line of the
display. If the "LOCK" key is pressed again (> approx. 2s), then the
operating elements are released again (unlocked).

4.4.3 Controlling the output

OUTPUT The output of the power supply is switched on or off via a relay with the
"OUTPUT" key. In the process, the status "On" or "Off" is indicated at
the bottom right of the display. On switching the power supply on, the
output is always in switched-off status.
