Health Mode Alarm
The Health Mode Alarm alerts you when preventative maintenance becomes necessary to ensure reliable sensing. The
Health Mode output 2 is Active when the system is OK and operating normally. Health Mode output 2 becomes Inactive
when the system is in a marginal state because of contamination. The system still operates normally and can detect small
objects, but is nearing the alarm state. When the system is completely contaminated and unable to ensure reliable
sensing, the system goes into the alarm state. In the alarm state, the discrete output 1 is forced to the blocked state and
can no longer be used to detect small objects.
The sensor may enter Health Mode Alarm for any of these reasons:
1. When first powered up; the fiber optic array may already be contaminated
2. If the Window SET procedure fails, indicating the fiber optic array is contaminated and the sensor could not set a
valid clear-state light level for reliable detection
3. If the fiber optic array is contaminated enough that the auto compensation tracking algorithm cannot sufficiently
adjust the thresholds to ensure reliable detection
4. If the fiber optic array is blocked for more than 2 seconds
Return the system to normal operation by cleaning the fiber optic array and performing a Window SET to reset the clear-

Discrete output 1: Forced to Blocked State (i.e. in dark
operate, the output is conducting)
Health Mode output 2: Inactive
Indicators: Arrow Icons 1 & 2 Red
Alarm: System not operational; system
maintenance required
Programming Options
Light/Dark Operate Selection. Toggle to select the condition for which the output will conduct: when the object is
present or when the object is absent.
Threshold Offset Percentage. 2%, 3%, 4%, 5%, 10%
Dynamic Event Stretcher (DES) Selection. The output is held ON (OFF in Light Operate) for a percentage of time
longer than the detection event duration.
Options: 0%, 25%, 33%, 50%, 100%
(e.g., If the Dynamic Event Stretcher was set at 50%, a 1 ms event would be stretched to 1.5 ms)
Display Orientation. Normal or inverted
Display Mode. Health Mode (100%–0%); Percentage Blocked (0%–100%); Signal Level (ADC value); or Counter Mode
(0–9999)
Power Level/Speed Selection. High-Speed (HS) (150 µs response, 50 µs repeatability); High-Power (HP) (225 µs
response, 75 µs repeatability); or Super High-Power (SHP) (300 µs response, 100 µs repeatability)
