Refer to figure 3-10, which includes drawings that outline sensor wiring.
For sensor wiring of PH8EFP, PH8ERP, PH8EHP, OR8EFG, OR8ERG, HA405, HA406, HA485,
DPA405, DPA406, DPA485, HF405, DPAS405, DPAS485 and FU20, see APPENDIX 2 (Chapter 11).
The EXA analyzers can be used with a wide range of commercially available sensor types, both from
Yokogawa and other manufacturers. The sensor systems from Yokogawa fall into two categories; the
ones that use a fixed cable and the ones with separate cables.
To connect sensors with fixed cables, simply match the terminal numbers in the instrument with the iden-
tification numbers in the instrument on the cable ends.
The separate sensors and cables are not numbered, but instead use a color-coding system. The elec-
trodes have a colored band incorporated in the label on the connection cap:
• Red
for measuring electrodes (both pH and ORP)
• Yellow
for reference electrodes
• Blue
for combined sensors with both measuring and reference elements in the same body
• Green
for temperature sensors
The recommended procedure is to color-code each end of the cables to match the sensors with the color
strips provided with each cable. This provides a quick way to identify the ends of the cables belonging to
a particular sensor when they are installed. (The procedure for fixing the identification labels is described
in detail in the instruction sheet provided with the cable.)
