ZERO TARE ALARM
(former: DUMP ALARM)
ALARM CODE:15
Problem: Load Cells outside of acceptable
Calibration.
Weigh bin empty weigh above tare high upper limit (TH parameter) or
below tare lower limit (TL parameter). If above TH (upper limit) weigh
bin dump valve opens and closes repeatedly. Possible causes:
There is material in the weigh bin that will not dump out.
The dump flap may be stuck.
The load cells are hung up or obstructed.
The load cells are out of calibration.
Solution: Clear material jam, check dump valve for free movement,
Check that weigh bin and load cells are free from contact with door
and back of enclosure, verify weigh bin is installed correctly. If weigh
bin is empty and weight reading on-screen is above TH parameter or
below TL parameter then recalibration load cells. See page 35 (zero
only) and
Error! Bookmark not defined. (zero and full calibration).
OVER WEIGHT ALARM
ALARM CODE:20
Problem: Over Dispense triggered by Alarm
Parameter
First three digits of the component specific AL parameter ( 000 00) are
used to STOP and ALARM the blender if an over dispense occurs by
a specified number of grams or percent.
Grams: enter 001 to 499 in
the first three digits. Percent: enter the number
“5” in the first digit.
When percent is enabled, the 2
nd
and 3
rd
digits are the percent (01
–
99). In the first digit of the _AL parameter, 6
– 9 are invalid digits.
Solution: Determine cause of over dispense.
WAIT FOR RECIPE ALARM
ALARM CODE:21
Problem: Recipe Request option did not receive a
recipe within the 2-minute timeout period.
When enabled the Recipe Request option uses the Recipe Number
Tag to request a recipe over communications. If the recipe number is
changed to a value between 100 - 65535, the 2-minute Recipe
Request timer starts and monitors for a change in the recipe. If a
recipe is not received within the timeout period, this alarm sounds.
Solution: Check Recipe number, check status of communications.
WEIGHT DROP ALARM
ALARM CODE:22
Problem: Weigh Bin loosing weight during a cycle.
This alarm is triggered by a loss of more than 20, 40,or 80 grams
(model dependent) during a dispense cycle. This serves to detect
and report a weigh bin problem, such as material leaking from the
bottom of the bin. See WDD parameter, Weight Differential Detect.
Solution: Examine weigh bin for issues with material retention such
as weigh bin flap closure problems, material jam, angel hair causing
leak, low air pressure, damage to weigh bin or obstruction to weigh
bin closing.
