Calibration

3.3.6 High Level Fail Safe Blind Calibration of Control w/Flush Sensing

Element

(Alarm when chute is full at sensor)

A. Start with sensing element uncovered, (no material at

sensing element), and tuning adjustment full counter-

clockwise (

ccw

). At this point red LED will be ON.

B. Turn adjustor clockwise (

) until LED just turns OFF.

C. Test unit by turning adjustor slowly counter-clockwise

(

ccw

), then clockwise (

) 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.

D. If above operation is satisfactory, then continue turning

adjustor clockwise (

• One (1) turn for granulars containing moisture. (1 = 4PF)
• One half (1/2) turn for dry insulating powders.

Calibration is Complete

1/4 TURN MAX.

3.3.5 Calibration of Adjustable Differential Units (HLFS and LLFS)

A. Put Fail-Safe switch in

HLFS

position.

See Section 2.6.3

B. Turn Set Point adjustor to full counterclockwise (

ccw

)

position.

C. Turn Differential adjustor to full counterclockwise (

ccw

)

position as well.

See Figure 2-5

D. Adjust material level to lower point of desired control

band.

E. Slowly turn Set Point adjustor clockwise (

) until

instrument just operates (LED changes state).

F. Turn Differential adjustor to full clockwise (

) position

(maximum differential).

G. Raise material level to upper point of desired control

band.

H. Slowly turn the Differential adjustor counter-clockwise

(

ccw

) until the LED changes state.

I. Select desired Fail-Safe position.

Calibration is Complete
