COUNTING SENSOR (revised 2022-01-19)
❑
Detects solid (opaque) product and translucent or clear product, such as gel caps.
❑
Automatically and continuously adjusts light level for maximum sensitivity
❑
Compensates for dust buildup and sets alarm if conditions become marginal.
7.3.1.
THRESHOLD ADJUSTMENT
– How Much The Light Level Must Drop To Count.
When the light in the counting window is unblocked, the sensor detects 100% of the
light. When an object falls through the window, the light is blocked. If the threshold
size is set to 40%, the sensor will send a count signal when 40% of the light is
blocked; that is, when the light level falls below 60%. The sensor will reset when the
light level rises above 60% again. This is the factory setting and works with most
products. The threshold can be reduced to as low as 5%.
Adjustable in 5% increments
Light bar 1=5%
Light bar 8 = 40% (factory setting, most products)
•
THRESHOLD FACTORY SETTING = 8 (good for all but the smallest pills)
7.3.2.
ONE-SHOT DELAY ADJUSTMENT – How Long the Count Signal Stays On.
This is a feature for CLEAR PRODUCT ONLY. It is used to stretch the count signal
so a product with a clear center does not produce a “double” count. Normally set at
the minimum (5 ms) for solid product. For clear or opaque product, increase the one-
shot according to the length of the product. For example, 10 ms for round gel caps
.25” long, or 40 ms for oblong gel caps .90” long.
Adjustable in 5 millisecond increments
Light bar 1 = 5 ms (factory setting, for solid product)
Light bar 8 = 40 ms (for long clear products)
•
ONE-SHOT DELAY FACTORY SETTING = 1 (good for all solid product)
•
ONE-SHOT DELAY 2-8 is for CLEAR PRODUCTS ONLY
•
With ANY product, if the ONE-SHOT DELAY is set too high, it will cause
OVERFILLS (too many pills in the bottle)
•
With CLEAR product, if the ONE-SHOT DELAY is set too low, it will cause
UNDERFILLS (too few pills in the bottle).
