Adjustment
Setting the Sensitivity Potentiometer (5) requires no tools. To adjust the sensitivity potentiometer, (5).
simply turn the shaft of the potentiometer (5) counter-clockwise (CCW) to increase sensitivity and
clockwise (CW) to decrease sensitivity.
Periodic Maintenance
Periodic maintenance/inspection is recommended. Customer may determine appropriate time
interval for their installation. Check the following items:
1. Remove accumulated dust, dirt, and moisture from inside of the enclosure.
2. Inspect all electrical connections and wires. All connections should be secure and free from
corrosion.
3. Test per section “Testing” (page 12)
4. If AC line lightning protection is installed: Verify that the LED on the AC Line protector is
ON.
CAUTION:
Failure to routinely inspect for and correct this condition may result in
damage to the unit in the event of a lightning strike. If at the time of inspection the green
LED is blinking four times per second rather than the normal once per second, the
microprocessor’s “watchdog” feature has detected an error in its operation, but has
corrected the problem. If it blinks sixteen times per second the error was caused by a
power “brown out”; that is, the 120 VAC line voltage at some time has fallen below the 98-
132 v operating range.
NOTE:
these fast blinking rates are intended to alert users to a past
problem that has been self corrected, not that there is an existing problem. These problems
may have been of such short duration that they were not noticed. The blinking LED may be
reset to once per second either by pressing the small reset switch button near the LED, or
by moving the on-off slide switch briefly to off, then back on.
