3.10.2.1 Connecting the Isolated Analog Input
(Density) Wiring
•
Ensure the jumper on
JP4
on the motherboard is
installed across pins 1 and 2 before attaching signal
connections.
•
Connect the appropriate density measurement device
output cable to terminal block
J9
according to Table 3.4.

Table 3.4: Isolated Analog Input (Density) Terminal Block
Layout
If a density meter output will not be connected to the
transmitter, do not connect anything to terminal block J9.
Density information representative of the material under process
conditions must be entered into the transmitter in order to accurately
calculate viscosity in standard viscosity units.
This may be accomplished via
•
Real-time density data input
to the transmitter’s
Isolated Analog
Density Input;
•
Manual entry of a static representative density into the transmitter
which is used for all viscosity calculations.
If density information is not provided, the calculated results in standard
viscosity units will be inaccurate unless the process material
density =1.00 g/cm
3
(the default factory setting.)
The density parameter may be configured via the transmitter keypad
(see 4) and/or the ViscoSite software (see 5.)
Digital Relay Outputs
The ViscoSite transmitter provides 2 digital relay outputs. These relay
outputs are primarily used to provide notification of changes in
measured parameter values that are outside the expected range. They
are especially useful when real-time data logging is not required and
the exact value of the parameter is not of interest.
