3.3.7 Low Level Fail Safe Blind Calibration of Control w/Flush Sensing
Element
(Alarm when chute is empty at sensor)
1. Start with sensing element uncovered, (no material at
sensing element), and tuning the SetPoint adjustor to full
counterclockwise (ccw) position. Red LED will be OFF.
2. Turn the SetPoint adjustor clockwise (cw) until the Red
LED just turns ON.
3. Test the unit by turning adjustor slowly counter-clockwise
(ccw), then clockwise (cw) to determine differential of the
electronics.
If ON/OFF differential of LED is more than one quarter
turn, unit is not operating correctly. Please consult
factory service department for assistance. This is a simple
function test of the electronics.
4. If above operation is satisfactory, then continue turning
adjustor clockwise (cw):
• One (1) turn for granulars containing moisture. (1 = 4PF)
• One half (1/2) turn for dry insulating powders.
Calibration is Complete
When excessive build-up on sensor occurs, turning adjustor
clockwise will generally eliminate a false high-level signal. Build-
up may continue to form, or, it may drop off.
