4-20 mA auxiliary output wiring
You can wire an auxiliary output for 4–20 mA.
The prerequisites are:
Model Number - Table 3 = 1XX or 4XX
Refer to Figure 2-22 and follow the procedure in Table 2-22 to wire 4–20 mA auxiliary output.
Table 2-22 4-20 mA auxiliary output wiring
Open the recorder door. Loosen the captive screw in the chart plate and swing the plate out.
Locate connector J2 near the bottom of the auxiliary output printed circuit board (refer to
Figure 2-22 for location).
Remove the unwired plug from J2.
Run the output wires through the desired knockout.
For CE Mark conformity, install the ferrite filter as shown in Figure 2-11.
Strip insulation from the end of each wire.
Loosen the screws in plug J2 terminals and position the plug as you would to plug it into J2.
Observing the polarity, insert the wires into the appropriate screw clamps as shown (refer to
Figure 2-22). Tighten the screws to secure the wires.
Install the wired plug into J2.
Be sure that the 4-20 mA auxiliary output is aligned. Refer to subsection 8.4 Auxiliary Output
Calibration.
The 4-20 mA output on the control output board can also be set up for an Auxiliary
retransmission output if it is not being used for a control output. This requires model selection
option Table II = 10, 60, 66.
TIP
Auxiliary output 2 and Auxiliary output 3 use Control current output 1 and Control current
output 2 if Control “OUT ALG” is not set to “CURRENT”.
