computing the fluid density for the measured temperature and adjusts the volumetric or mass
delivery total.
Simply stated, temperature compensation adds pulses to the pulse total when the detected
temperature is colder than the products reference temperature and subtracts pulses when the
product temperature is warmer than the reference temperature. The rate at which the pulses
are added or subtracted is determined by the measured temperature departure from the
products reference temperature.
Modes of Operation:
The
CDS1000
program offers 3 modes, Operating, Programming, and Prove. Any mode that
can affect the calibration of the
CDS1000
is password protected. The
CDS1000
has a 2 tiered
password level of security, Privileged and User/Weights and Measures. The Privileged
password is maintained exclusively for Factory use and allows access to ALL menu options.
The Weights and Measures password allows access to all displayed menu options except two,
Initialization Options 5,8 Hardware test/calibrate and Loaner respectively.
Operating Mode
The Operating mode is the power up mode for the
CDS1000
; all others must be accessed
with a password. The Operating screen containing all delivery information is the normal
display for this mode. The Detail screen is also accessible in this mode without a password.
Programming Mode
The Programming mode and associated menu’s permit the
CDS1000
to be configured to the
operating conditions of the application. When accessed, the first Display is
CDS1000
Initialization Options menu containing 9 options. Options 2,3,5 and 8 are password protected.
Options 5,8 require a Privileged password and are intended for Factory use only
..
Prove Mode
The Prove mode permits convenient calibration of the trailer’s delivery system. This mode
temporarily aborts certain safeguard features and therefore is password protected. To access
this mode, depress the SETUP key while in Operating mode. The system will prompt for a
password, either User/Weights and Measures or Privileged, to be entered. If an incorrect
password is entered or the ESC key is depressed, the
CDS1000
will revert to the Operating
mode. The Prove mode allows entering, changing or viewing the Kfactor. The Prove mode is
retained until the
CDS1000
is either turned “Off” or no flow activity is detected for 5
minutes. The Prove mode has the following operational characteristics:
The

message on the operating screen
A password is not required to change the Kfactor
The pump cooldown timer is disabled (pump enabled)
The Totalizer can be reset regardless of the presence of flow
