2.5.2 Analog Input Wiring

Introduction

The input for pen channel 1 is wired to TB2 on the printed circuit assembly (PCA) on the right (when facing recorder). The input for pen channel 2 is wired to TB2 on the PCA on the left.

Each input can be wired for thermocouple, RTD, mA, mV, or Volt actuations.

ATTENTION

Make sure you have configured the recorder to accept the desired input type. See Section 3 – Configuration, Startup, and Operation of Recorder Without Display or Section 4 – Configuration, Startup, and Operation of Recorder With Display.

Procedure

Refer to Figure 2-11while following the procedure in Table 2-9to install analog input wiring.

Step

Action

ATTENTION To avoid damaging the recorder, be sure that you install the power wires into the correct screw terminals as shown in Figure 2-9and Figure 2-10.

1Turn off the power to the recorder.

2Open the recorder door. Loosen the captive screw in the chart plate and swing the plate out.

3Locate terminal block TB2 on the right edge of the printed circuit assembly for pen 1 (refer to Figure 2-11).

4Run the input wires through the appropriate conduit hole (see Figure 2-7and Figure 2-8). DO NOT bundle them with the power wires.

5Strip 1/4-inch maximum of insulation from the end of each wire and form end to fit under the screw terminal on the removable connection block.

6Insert the wires under the appropriate screws for the applicable input type. See Figure 2-11for specific input actuation wiring.

Tighten the screws to secure the wires.

7If the recorder has two pens, repeat Steps 3 through 6 to wire the input for the second pen channel to TB2 on the PCA on the left inside of the recorder.
