Operation
Using the 2564 Thermistor Scanner Module with the 1560
Black Stack
is very
simple. The following sections explain the steps for setting up and using the
2564 to measure with thermistors. For instructions for installing the 2564
Thermistor Scanner Module onto the 1560 see Section 4.1.
11.3.1
Wire Configuration
The 2564 Thermistor Scanner Module can accept sensors with two, three, or
four wires but all the sensors connected to the same row must be of the same
type. The connectors are arranged in two rows—front and rear. Each row can
be independently configured for four-wire (or two-wire) or three-wire opera-
tion. The wiring type is selected using the
SET UP DEVICE
function in the
MODULE
soft-key menu (see Section 5.4.2). Select the THRS device. A win-
dow appears showing the setup parameters for the 2564 Module:
SET UP DEVICE: THRS 3
CURRENT(µA): AUTO
LR
WIRES FR: 4
WIRES RR: 4
SAMP PER: 2
RES RANGE: AUTO
Select the wiring type for the front row and rear row with the WIRES FR and
WIRES RR parameters respectively. Move the cursor from line to line with the
UD
buttons. The values of parameters can be changed using the
LR
but-
tons. Press
ENTER
to set the parameter. If 3 is selected for one row all the sen-
sors connected on that row must be three-wire. If 4 is selected for one row all
the sensors connected on that row must be two-wire or four-wire.
11.3.2
Connecting a Probe
Four-wire sensors are connected as shown in Figure 17. The shield, if used, is
connected to pin 1 on the left. One pair of wires connects to pins 2 and 3. The
opposite pair of wires connects to pins 4 and 5. Pins 2 and 5 source current and
pins 3 and 4 sense potential.
When using four-wire sensors be sure to check that
the wiring configuration for that row is set to 4 as explained above!
Note:
There are two types of sensor connectors. One has the wire holes facing
the front of the module and one has the wire holes facing the back of the mod-
ule as shown in the connector details in Figure 17.
