Scale Error No. 54
(Figure 7-2)
Pedestal not installed.
You will typically receive a Fluidmove error message
when the pedestal is not installed on the scale. There
is a minimum weight that must be placed on the
scale in order for it to read properly.
Unstable scale
Lid not on scale.
Verify that the scale lid is installed. Air turbulence will
cause scale instability issues.
Dispensing area door open.
Verify that the dispensing area door is closed. Slight
air turbulence can cause unstable readings.
Floor vibration.
In some rare cases, vibration through the floor can
cause scale instability issues. This is most common
where the dispensing system is not installed on a
concrete floor.
NOTE The scale can also be tested from the Fluidmove Terminal Mode. See instructions below.
To test the scale from the Fluidmove terminal mode:
1. In the Fluidmove Main Window, select
Tools.
2. In the Tools menu, click on
Terminal and then on Scale .
3. Use the following commands to check the scale responses:
ESC+P (escape key and capital P) Outputs the current scale value to the terminal
screen.
ESC+S (escape key and capital S) Restarts the scale but gives no response.
ESC+T (escape key and capital T) Tares and Re-zeroes the scale.
4. If the scale does not respond to those commands, then there may be a software
configuration issue. Verify the scale is configured from the configuration menu. The scale
type selected should be
