Output Voltage Selection: (Continued) To change from 24VAC output power to 24 VDC
output power , unplug the white
AC
plug from the connector shown below and plug in the white
DC
plug.
Timing:
The force valve actuates when the first level of the foot switch is closed.
It automatically de-activates when the
COOL
temperature is reached, or
in the event of a reflow alarm.
The head cool valve is user-programmable to be ON or OFF. It is
independent of the reflow process cycle. It is used to prevent the
thermocouple holder from overheating.
The solder cool valve can be user-programmed to activate at the start of
the
COOL
period. It automatically de-activates when the thermode
temperature reaches either the
COOL
or
PREHEAT
temperature which
ever is lower. It is used to cool the hot thermode quicker.
