2. If the Serial Setpoint logical input is on, the controller reverts to using the Fallback Setpoint.
See page 18.
NOTE: It is very important that no two controllers on the same serial line have the same controller address!
This would result in both responding to a message at the same time. The results would usually be
unusable data.
Set Date and Time
For setting the date and time parameters, follow the direction given the Numeric Entry
Screen section found on page 9. The application and controller hardware has been
tested for the millennium shift, with regards to operation across the shift and the year
2000 being a leap year. There are no known problems. The controller is “Y2K compliant”.
PCAD Settings
WARNING: The following values are set at the factory and should never be changed.
CAL
This value is used by the PCAD Converter to control an amount of positive offset added to the load
cell signal. It is used to simulate load on the load cell during an Electronic Calibration, an is
normally zero. In the rare occasion of negative dead load, a positive value can be present. The
actual offset signal is added is 0.2 mV/V times the Cal Set number.
ZERO
This value is used by the PCAD Converter to control an amount of negative offset added to the
load cell signal. It is used to electronically remove dead load from the load cell signal. This allows
the PCAD to operate at a higher gain and achieve better resolution when measuring the load cell
signal. The actual offset signal is added is -0.2 mV/V times the Zero Set number
GAIN
This value is used by the PCAD Converter to control the Gain setting of the PCAD Converter. The
amount of Gain depends on how much dead load and live load there will be on the scale. The
actual Gain of the controller decreases as the PCAD Gain Value is increased. This value is
normally set to 15.
Set Status
This value is the hardware calibration setting and is preset at the factory. This value should not be
changed.
WARNING: This number should not be changed from it’s setting of 2. DO NOT CHANGE THIS NUMBER!
CAL 0
ZERO 0
GAIN 15
Set Status 2
Number of PCAD’s
If your application requires two PCAD’s this number must be set to two to insure proper operation
of the application software.
Allowed Difference
This parameter is the allowed difference in counts between two installed PCAD’s. If this value is
exceeded the General Alarm PCAD Discrepancy will activate.
