DR4300 Circular Chart Recorder

Insulation of output wires

The insulation of wires connected to the relay output terminals shall be rated for the highest voltage involved. Extra Low Voltage (ELV) wiring (input, current output, and low voltage control/alarm circuits) shall be separated from HAZARDOUS LIVE (>30 Vac, 42.4 Vpeak or 60 Vdc) wiring per Table 2-6.

Procedure

Follow the procedure in Table 2-13to wire the discrete outputs.

Refer to Figure 2-14for wiring electromechanical and solid state relays. Refer to Figure 2-15for wiring open collector outputs.

Refer to Table 2-12to see the output function of each terminal with the available output algorithms and options.

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 blocks TB3* and TB4* on the bottom right edge of the printed circuit assembly (PCA) for pen 1 or pen 2.

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

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

6Insert the wires under the appropriate screws for the applicable relay output as shown in the figures. Tighten the screws to secure the wires.

*TB3 is output 2. TB4 is output 1.
