S A potentiometer labeled “Fault” limits the amount of filling time in case
of level sensor failure. It is only for overflow protection. The factory
setting is at the 12 o'clock position, sufficient in most applications.
The time can be adjusted from 5 to 115 seconds. For reference, the 9
o'clock position is 22 seconds and the 3 o'clock position is 98
seconds.
S A potentiometer labeled ”AIR” is a pre‐vibrate timer for the optional
storage bin vibrator kit. The range for this potentiometer is 0 to 20
seconds. When installed, this vibrator will activate up to 20 seconds
before the fill system activates and stay on until the level sensor is
satisfied. This kit is well suited for adhesives and plant conditions that
are prone to bridging.
S A dip switch labeled SW1 is preset at the factory. Position M1 should
always be OFF and position M2 should always be ON.
S A terminal block labeled ”XT2”. An optional light tower may be
attached here. The functions of the light tower are
‐ Fill (Blue) - visual
‐ Fault (Red) - visual
‐ Fault (Alarm) - audible.
NOTE: The fault outputs will engage simultaneously.
(7). Sensor
The level sensor detects the level of adhesive in the melter tank. When the
adhesive falls below the set point, the level sensor sends a signal to the Fulfill
control box.
For optimal performance based on specific applications, see the Level
Sensor Adjustment and Calibration detailed later in the manual.
