The  ones  switch  is  in  increments  of  one  second  and  the  tens  switch  is  in  increments  of  ten  seconds.    As  an 

example, to set the motor timer to 20 seconds, turn the tens rotor to setting 2 and turn the ones setting to 0.  The 

solenoid timer setting would be set in the same manner. 

 

4.1.9.5  Solenoid Timer Switches (Tens & Ones) 

 

These rotary switches can be adjusted to vary the length of time the clutch solenoid is energized to allow the auger 

tube to rotate in  the product stream during each sample collection cycle. 

 

NOTE: 

THE  CLUTCH  SOLENOID  TIME  IS  ADJUSTED  SO  THAT  THE  AUGER  TUBE  MAKES  ONE 

REVOLUTION.  WHEN THIS TIMER TIMES OUT THE SOLENOID WILL STAY ENERGIZED VIA THE FIELD 

WIRING THRU THE LIMIT SWITCH.  WHEN THE LIMIT SWITCH IS ACTIVATED POWER TO THE SOLENOID 

WILL  CEASE  AND  THE  CLUTCH  WILL  NO  LONGER  DRIVE  THE  AUGER  TUBE.    IF  ADDITIONAL 

REVOLUTIONS  ARE  DESIRED:  ADD  SIX  SECONDS  TO  THE  SOLENOID  AND  MOTOR  TIMER  SETTINGS 

FOR EACH ADDITIONAL REVOLUTION. 

 

Utilizing a small screw driver turn the slotted rotor of the tens and/or ones switches to desired length of time the 

sample tube clutch solenoid is energized during a cycle.  The time period can be adjusted from 1 to 99 seconds.  

The timer is factory set at 4 seconds.  Refer to Section 4.1.9.4 for further explanation on time settings. 

 

4.1.9.6  Motor LED Indicator 

 

This LED (D1) is illuminated when power is present to K-1 relay coil on the PC board.  It is a visual signal showing 

when the motor should be running. 

 

4.1.9.7  Solenoid LED Indicator 

 

This LED (D2) is illuminated when power is present to K-2 relay coil on the PC board.  It is a visual signal showing 

when the clutch solenoid should be energized. 

 

4.1.9.8  Mode Select Switch 

 

The switch, located at the lower center of the circuit board, determines the sequencing of certain internal controller 

events. 

 

As  this  board  is  used  in  controllers  for  several  different  samplers,  MODE  switch  settings  allow  the  board's 

functions to be tailored to the requirements of the various samplers. 

 

NOTE: 

GSS-U SAMPLERS REQUIRE THE MODE SWITCH TO BE POSITIONED ON SETTING "2" (TWO).  

IF THE MODE SETTING IS NOT CORRECTLY SET, TURN POWER OFF TO THE CONTROL PRIOR TO RE-

SELECTING.  THE PC BOARD WILL ONLY CHANGE MODES WHEN POWER IS INITIALLY APPLIED.

 

 

4.1.9.9  Terminal Strip 

 

This 20-position barrier terminal strip is located along the left edge of the circuit board.  It serves as the controller's 

interface and connection point for all external circuits and for the components mounted on the enclosure's front 

panel.  Refer to the certified electrical drawing(s).
