2.1 Controller Mounting
The controller is surface mounted by four 0.172” diameter mounting holes located in the corners
of the case that are sized for screws as large as #8. They are located on a rectangle 159mm x
121mm (6.26” x 3.58”). The depth of the case at the mounting holes is 0.120”. The mounting
holes are accessed by removing the four screws that retain the clear cover of the controller.
The Controller can operate in any orientation however, for ease of use, it is best to orient the
unit with the display and text right side up. The case is IP65 rated so the unit may be mounted
inside or outside of a protective cabinet. Take care that the cable pathways may affect the unit’s
ability to fully prevent the ingress of liquids. See Mechanical Specifications on page 28 for full
details.
2.2 Probe Mounting and Positioning
The P80T30P probe must be mounted using non-metallic materials such as Delrin to insure the
mounting hardware does not interfere with the sensing of the target material. No metal should
come within half the probe diameter (15mm) of the sides of the probe.
The distance from the P80T30P probe face and the material sample can range from direct
contact to as much as ½ inch, depending upon the metal thickness. However, whatever the gap,
for proper operation the separation distance must be held constant between gauging and
calibration.
2.3 Logic I/O Wiring
The logic inputs and outputs of the DS600 family of controllers are electrically isolated from the
controller circuitry. However, the integrity of the isolation and the type of signal (sourcing or
sinking) for a particular application are determined by the connections made to the reference
lines IN REF, SEL REF, and OUT REF.
For a given signal type, e.g. sourcing or sinking, the reference signals for inputs and outputs are
opposite. For sourcing signals, the input reference is connected to common and the output
reference is connected to the power supply high side. Conversely, for sinking signals, the input
reference is connected to the power supply high side and the output reference is connected to
common.
Additional +24V and COM terminals are available on the DS600 family controllers to facilitate
appropriate connections to the reference inputs if isolation is not required. If isolation is required,
the power supply common and high side of the isolated supply (perhaps power supply powering
the PLC connected to the DS600 controller) must be connected to the appropriate reference
terminals.
Just as it is possible to mix sourcing and sinking between the INP, OUTPUTS, and CAL MEM
groups of signals, it is also possible to mix isolated and non-isolated operation between these
same three groups.
In further discussions in this manual, the terms common and +24V will be used to signify power
common and high side respectively. These same terms will be used regardless if these
potentials are isolated or not from the power used to supply the controller, i.e. if isolation is
desired or not.
