Setup
2.1 Mounting the Controller
If necessary,
the rear connector assembly may be removed from the main case for wiring
(see Figure 2.1a for Square Mount, Figure 2.1b for Round Mount).

Controller Mounting Instructions
1.
Separate the display from the meter by squeezing the case (where
shown) and then unplugging the cable from the meter.
2. Slide the retainer over the rear of the case, but do not
engage serrations on case.
3. Pass the cable (from the display) thru a 1 3/4" diameter
hole in the mounting panel and connect to the meter (take care to
center the connector on the mating pins). While squeezing the case,
press the display and meter squarely together until they connect.
4. Check the display and gasket for proper alignment, then
slide the retainer tight against the backside of the mounting panel. |

Dip Switch Configuration
| The
settings of the DIP switch must be verified or set to comply with
your selection at the Input/Type menu (see Section 3.0 for Input/Type).
The DIP switch is accessible through an opening on the side of the
case. After carefully removing the controller from the case, see
Section 2.1 for instructions, locate the dip switch (see Figure
2.4) and set the switches according to the following tables. |

Thermocouple

Thermocouple Wiring Hookup
|
INPUT
CONNECTION EXAMPLES
The figure
below shows the wiring hookup for any thermocouple type. For example,
for Type K hookup, connect the yellow wire to the + (+S) terminal
and the red wire to the û (ûS) terminal. When configuring your
controller, select Thermocouple and Thermocouple type in the Input
Type menu (see part 3). |
2.5.3
Two/Three-Wire RTD
The figures below
show the input connections and input connector jumpers required to hookup
a 2, 3 or 4-wire RTD.
|
|
The
two-wire connection is the simplest method, but does not
compensate for lead-wire temperature change and often requires calibration
to cancel lead-wire resistance offset. |
|
|
The
three-wire
connection works best with RTD leads closely equal in resistance.
The controller measures the RTD, plus upper and lower lead drop
voltage and the subtracts twice the measured drop in the lower supply
current lead producing excellent lead-resistance cancellation for
balanced measurements. |
|
The
four-wire RTD hookup is applicable to unbalanced lead resistance
and enable the controller to measure and subtract the lead voltage
which produces the best lead-resistance cancellation.
When configuring your controller, select RTD type and RTD value
in the input .Type menu (see part 3) |
2.5.4
Process Current
Figure
2.5.4 Process Current Wiring Hookup
|
The
figure shows the wiring hookup for process current 0- 20mA.
When configuring your controller, select Process type in the
Input Type menu (see part 3). |
2.5.5
Process Voltage
Figure
2.5.5 Process Voltage Wiring Hookup
|
The
figure shows the wiring hookup for process voltage 0 - .1V, 0
- 1V, 0 - 10V.
When configuring your controller, select Process type in the
Input Type menu (see part 3). |
