POWER SUPPLY OVERVIEW

POWER SUPPLY FEATURES

1. AUTO SHUT-OFF
Like the STSS-PS2E, the MX-500P is equipped with a ground sensing
feature. The AMBER LIGHT illuminates when there is any break in the
ground. To reset, turn the power supply off and back on. If the ground has
not been re-established, the power supply will remain off.
2. TIME-OUT FEATURE
Your MX-500P comes with a time-out feature designed to maximize the life of
your tip cartridges. The time-out feature works by detecting a load difference
at the tip and sensing whether the tip cartridge has been used during the past
25-30 minutes. If no load change is sensed, the power supply shuts off. This
is indicated by the GREEN LIGHT going off. To reset, turn the power supply
off and back on.
3. OVERRIDE SWITCH
Because the time-out feature works off a load difference, sometimes the
power supply may not sense very light loads. If, for instance, an operator is
soldering 30 gauge wire with an STTC-522 (no sponge wipe), the power
supply may shut down after 30 minutes. To ensure operator satisfaction,
Metcal has equipped the MX-500P with an OVERRIDE SWITCH. To
disengage the time-out feature, unscrew the set screw several turns with the
provided Allen wrench. To re-engage, turn off the power supply and screw
the set screw clockwise until it feels tight. When the power supply is turned
back on, the time-out feature will be restored.
