NSTALLATION
The cable should not be placed in a tray or conduit with wires attached to heavy inductive loads
or SCR drives. A separate conduit is recommended.
1.5 Interconnection
The E-Scan offers many options for external device connections.
1.5.1 Analog Outputs
In addition to voltage outputs, the E-
Scan also offers current outputs for the
measurement and also the temperature.
The measurement is a standard output
and temperature is an option. Output
for these readings is a 4 to 20 mA
signal that is referenced to ground
(non-isolated) so that any device that is
connected to these outputs must have a
floating (or isolated) input. Isolated
current output modules are available as
an option.
The output for the measurement
reading is found on
TB 3
terminals
1
and
2
. Terminal 1 is the positive output
for both the isolated output option and
the standard non isolated output
module. The output for the temperature
is located on
TB 3
terminals
3
and
4
,
3
being the positive output in this case.
The modules on the top of the interface
board represent the output modules.
The one on the left
U1
is the output
module for the measurement.
U2
is the output module for the temperature. The other modules
(
U3
and
U4
) are for optional features and are explained in the optional addendums to this
manual. It is an easy process to change from a non-isolated module to an isolated output module.
You must first remove the power supply, then unplug the non-isolated module and replace it with
the isolated module. The isolated modules are blue potted modules while the non-isolated
modules are bare board modules. If a 0-10 voltage output is desired then
TB 4
terminal
1
is the
measurement output and terminal
2
is the temperature output. Terminal
3
is the common for
both of these outputs.
