4.1.8 Digital Display Counter C-1 (Optional)
As arranged for use in this system, the counter operates in the DOWN & STOP mode. When the AUTO mode is
selected, the illuminated display resets to the value dialed in to the Three Digit Preset. Immediately, the counter
begins counting down. When the illuminated display reads all zeroes (000), the counter has "counted out" and
initiates a sampling cycle. The auger tube rotates once to collect a sample, and the auger rotates to empty out the
sampler. When the auger motor is energized the counter C-1 is reset (powered off). When the motor stops, the
counter display resets to the preset value and another counting interval is initiated. If the controller is shut off or
the mode switched from AUTO to MANUAL, the counting cycle is terminated. When power is restored or the
AUTO mode is again selected, the display is reset to the preset value and another cycle begins. NOTE: A new
counting cycle can be initiated ONLY after the sampling cycle has completed.
A. External Settings
1. THE DISPLAY:
The high intensity blue fluorescent display consists of three digits and a Counting Bar with a special
Count-Out symbol. The Counting Bar appears to the right of the digits and blinks once every count,
regardless of range. When the delay relay is energized at count-out, a triangular Count-Out symbol
appears to the left of the digits.
2. SETTING SWITCHES:
The three digits are set with the rotary switch knobs located beneath each digit. These knobs can be
rotated in either direction (CW or CCW), and they are "pull" removable, if digit set security is desired.
Changing one or more digits, during counting, will instantly be reflected by an equivalent change in the
counter's display. Setting all three digits to zero will cause instant count-out of the counter.
B. Internal Settings
THE 366 DIGITAL DISPLAY COUNTER MUST BE REMOVED FROM ITS HOUSING TO ALTER THE
COUNT RANGE:
The 366 has three ranges.
1x = Counts single pulses to 999
10x = Counts every tenth pulse to 9,990
100x = Counts every hundredth pulse to 99,900
Each range is selectable using finger force on the white plastic lever behind the front face of the
counter. In two of the three possible lever positions, an indicator will appear in a range window
located on the front face of the counter. When nothing appears in this window the count is in the x 1
range.
NOTE:
THE COUNTER CHASSIS AND THE HOUSING ARE POLARIZED SO THAT THE CHASSIS
CANNOT BE INSERTED INTO ITS HOUSING UPSIDE-DOWN. IF THE COUNTER IS FORCED INTO THE
HOUSING UPSIDE-DOWN DAMAGE WILL RESULT.
