1
Simultaneously press once on
both UP and SET buttons.
Note: Ensure no strip is present
or common background while
doing this step.
Next, displays any value, and blinking. Example:
2
When all settings are done, "DTM" and "1 spot" indicators will light up in step 1.
DTM (orange light) stands for datum/universal change detection (UCD)
1 spot (green light) stands for sensor stability
3
Press UP or DOWN button to
adjust value.
If set value > display value in Step 1, press UP
If set value < display value in Step 1, press DOWN
After adjusting the value, new value will blink and immediately
change on screen. It will be autosaved after a while.
The LED indicator at the side will illuminate, which means the
signal is successfully detected in the machine.
See 3.7.5.2 How to Set Threshold Limit in Strip Sensor for further
details.
4
Add off delay in sensor. The purpose of this setting is to prevent a false alarm signal from a reflective
die telling the system that the strip is absent. See 3.7.5.3 Delay Timer Settings for further details.
***blinking***
80 = Current threshold limit
100 = actual optimum reading

3.7.6 Fine-tuning the Slot Mapping Sensor
The slot mapping sensor and amplifier is assembled in the input elevator module (Station 20).
3.7.6.1 Production Test Flow and Running Concept
1. Half of the magazine is filled with strips and the other half is empty (Figure 3-45).
2. The strip barcode scanner will scan to see if there is a strip in the magazine slot. If the
magazine slot is empty, the gripper will skip the magazine lifting index during the strip
kicking process.
Example:
Figure 3-45 Magazine Slot With and Without Strip
Table 3-8 Example of Slot Mapping Test

Target Threshold Value in Amplifier

(a) With strip

(b) Without strip

• In the magazine slot with a strip (a), the threshold value shown in the amplifier increases
(higher value) when the strip is readable (strip present) and decreases (zero or lower value)
when the strip is unreadable (strip absent).
• In the magazine slot without a strip (b), the threshold value shown in the amplifier increases
(higher value) when strip is unreadable (strip absent) and decreases (zero or lower value)
when strip is readable (strip present).

3.7.6.2 Fine-tuning the Amplifier
1. Press and hold L/D for 3 to 5 seconds until the red light is on (Figure 3-46).
2. Press
UP or DOWN to increase or decrease the threshold limit, until the correct threshold
limit is displayed on the screen.
Figure 3-46 Fine-tuning the Amplifier
3.7.6.3 Setting the Amplifier Threshold Limit
The threshold limit decreases (zero or lower value) when the magazine contains a strip and increases
(higher value) when there is no strip in the magazine. Table 3-9 and Table 3-10 show sample readings
obtained in these two modes.

Perform Step 2 in 3.7.6.2 Fine-tuning the Amplifier and press the UP or DOWN button to adjust the
threshold limit until "43" is displayed on the screen.
