2.4 PCBRM15 and System 5.2 - Control Panel Overview
(A) Digital Temperature Controller - Microprocessor provides two programmable set points: Process
Temperature and Standby/Interlock Temperature. Digital readout of actual temperature is accurate
/-1% of full scale. (Thermocouple is located at bottom of solder pot).
(B) Solder Flow Rate Control – Process flow rate can be varied and controlled during the duration
cycle. There are three Solder Flow Rate Controls: Ramp Up, Process, and Ramp Down. The Flow Rate
Control adjusts the pumping speed of the solder to produce a level flowing wave through the Flow Well.
Too low of speed will not pump the solder against the pcb contacting all the component leads. Too high
a setting will cause solder to flood the board surface.
(C) Solder Duration Control – The length of the time solder flows in one cycle can be set. The
process cycle can be started by either depressing the START ON the Footswitch or pressing the
CYCLE Start-switch.
•
(D) Mode Switch - Automatic Mode – With the Timer Switch in the Automatic Mode, specific
timing logic is available up to 60 seconds and is adjusted and set by the Duration Control. The
settings between 1 and 5 give the range used for most applications. If the cycle needs to be
interrupted, pressing the STOP ON of the Footswitch will stop the cycle.
•
(D) Mode Switch - Continuous Mode – With the Mode Switch in Continuous, the Duration
Control Logic and Cycle Start Switch are now by-passed. Solder will flow until the STOP pedal
is depressed. Solder flow will not resume until the STOP pedal is released. The Continuous
Mode is operator controlled.
