2.7 Output Wiring Procedures
4-20 mA control output wiring
You can wire control output 1 or 2 for 4-20 mA output.
The prerequisites are:
 Model Number - Table 2 = 1X, 6X, X1, X6
Refer to Figure 2-16 and follow the procedure in Table 2-15 to wire 4-20 mA control outputs.
Table 2-15 4-20 mA control output wiring
Step
Action
1
Open the recorder door. Loosen the captive screw in the chart plate and swing the plate out.
2
Locate connector J1 near the top of the control output #1 printed circuit board (refer to Figure
2-16 for location).
3
Remove the unwired plug from J1.
4
Run the output wires through the desired knockout.
5
For CE Mark conformity:
 Install the ferrite filter as shown in Figure 2-11.
 Install the .0047µF capacitor as shown in Figure 2-16.
6
Strip insulation from the end of each wire.
7
Loosen the screws in plug J1 terminals and position the plug as you would to plug it into J1.
8
Observing the polarity, insert the wires into the appropriate screw clamps as shown (refer to
Figure 2-16). Tighten the screws to secure the wires.
9
Install the wired plug into J1.
10
Locate jumper position W6/W7 on the bottom left portion of the board. Make sure W7 position
is selected for 4-20 mA output.
11
Repeat steps 2 through 10 for control output #2 printed circuit board as applicable.
ATTENTION
Be sure that the 4-20 mA current output is aligned. Refer to subsection 8.2 Current
Proportional Output Calibration.
TIP
The 4-20 mA output can be used as a retransmission output if it is not used as a control
output.
