The solder cool valve will also activate at the end of POSTHEAT and de-activate when the thermode
temperature reaches either the COOL2, PREHEAT, or BASE temperature which ever is lower. The
solder cool valve is used to direct the cool air onto the thermode to force it to cool faster. The solder
cool valve supplies a connector-selectable 24 VAC or +24 VDC signal for controlling a user supplied
air solenoid valve.
FOOTSWITCH RESPONSE MODE
Press the 3 key toggle between ABORT and LATCH. This will deselect and select how the foot switch or
fire switch initiates a Control process cycle when an air actuated head is used.
Use ABORT when employing an operator to position parts. Releasing the foot switch at any time during
the heating cycle immediately turns off thermode heating and retracts the thermode from the surface of
the parts.
Use LATCH with automated or fixtured applications. Once the second level of a 2-level foot switch is
activated, the heating cycle will continue to completion unless the EMERGENCY STOP switch is
actuated.
