Failsafe
In a condition of device failure, known errors and input
power failure the outputs of the device resemble the ALARM
condition. This is meant to prevent overflow or dry run con-
ditions in case of failures.
Prevent Overflow - High Level Switch
: Failsafe High
(default) is set by moving the FS 1 and FS 2 switch for RE-
LAY 1 and 2 to OPEN position.
1. When not in contact with the material, LED turns
GREEN.
2. When in contact with the material, LED turns RED.

Use of LED Bar Display
: The bar display can be used
for two purpose:
•
Sensitivity: Refer to section Sensitivity for more details.
•
Display Mode: The display mode shows the material
distance from the instrument’s probe. The movement
of LEDs in upward direction depicts the movement of
