F.63 Scale Overflow
Equipment Constants
The following equipment constants will affect scale overflow detection as described. Variables ending in _S1 refer to Scale 1 and variables ending in _S2
refer to scale 2.
The SECS/GEM host should monitor c_OverflowCurrentCupWeightMG_S1/S2 for the current total weight in the cup.
c_OverflowAccumulatedTotalMG_S1/S2 and c_OverflowPreTareMG_S1/S2 are for internal use and individually are only part of the total cup weight.
Read carefully the affect that changing each equipment constant will have on overflow detection. It is recommended that the SECS/GEM host should not
alter the weight variables.
c_OverflowProtectionEnabled_S1/S2
• Enables or disables the overflow protection feature.
• Set variable to ASCII string “ON” to enable the feature or “OFF” to disable the feature.
c_OverflowMaxCapacityMG_S1/S2
• Contains the maximum scale overflow capacity for the scale.
c_OverflowWarningPercentage_S1/S2
• Contains the percentage of the maximum scale overflow capacity of the scale when the operator is warned to change the cup.
• Note that 1.0 = 100%, 0.5 = 50%, 0.25 = 25%, …
c_OverflowCurrentCupWeightMG_S1/S2
• Contains the current total weight in cup in milligrams.
• This equipment constant contains the total of the accumulated weight plus the pre-tared weight.
• Zeroing this value will also zero c_OverflowAccumulatedTotalMG_S1/S2 and c_OverflowPreTareMG_S1/S2.
• Normally this equipment constant should not be changed by the SECS/GEM host. The equipment will keep track of the weight in the cup.
• If this value is changed by the host, it is recommended that only a zero is written to this equipment constant to clear the total weight in the scale
cup. A non-zero value will have the following affect on the accumulated and tare value equipment constants:
c_OverflowAccumulatedTotalMG_S1/S2 will be set to the value of c_OverflowCurrentCupWeightMG_S1/S2.
c_OverflowPreTareMG_S1/S2 will be zeroed out.
