When a module is configured as non-redundant and uses a redundant IOTA, ensure that the lower slot is kept empty or if a module is plugged into the bottom slot, make sure that the module MUST be powered off.
You can wire input 1 or 2 for thermocouple, RTD, Radiamatic, mV, or 0-5 Vdc actuations.
The polarity for inputs #1 and #2 is identical.
The prerequisites are:
· Model Number - Table 1 = 1X00, X100
ATTENTION
For thermocouple or RTD inputs, calibrate the recorder to achieve the stated accuracy. Refer
to Section 7 – Input Calibration
Refer to Figure 2-13 and follow the procedure in Table 2-12 to wire Thermocouple, RTD, Radiamatic, mV,
or 0–5 Vdc inputs.

Step Action
1 Open the recorder door. Loosen the captive screw in the chart plate and swing the plate out.
2 Locate connector J2 on the printed circuit board for input 1 (refer to Figure 2-13).
3 Remove the unwired plug from J2.
4 Run the input wires through the desired knockout - DO NOT bundle them with the power wires.
5 For CE Mark conformity:
· Install the ferrite filter as shown in Figure 2-11.
· Install a .01µF capacitor across the J2 terminals and a .0047 µF capacitor at the
sensor end of the input wiring as shown in Figure 2-13.
6 Locate jumper position MA/W1 and make sure the jumper is in the W1 position. (See Figure
2-13 for the jumper positions.)
7 Locate jumper position W3 and make sure the jumper is in the proper position for your input
type. (See Figure 2-13 for the jumper positions.)
8 Strip insulation from the end of each wire.
9 Loosen the screws in plug J2 terminals and position the plug as you would to plug it into J2.
10 Insert the wires into the appropriate screw clamps for the applicable input type. See Figure
2-13 for specific input actuation plug wiring. Tighten the screws to secure the wires.
11 Insert the wired plug into J2.
12 Repeat steps 2 through 11 for input 2 printed circuit board as applicable.
