    2-12 <2. Installation, Wiring and Piping> 2.4.3 Cables Wired to Outputs These cables are used to transmit 4-20 mA DC signals and carry out BRAIN communication. Use shielded cables of 8 to 16 mm in finished outer diameter and 0.75 mm minimum in thickness (or a two-core shielded cable for single output). Wire the cables as instructed below: (1) Use cables that are 0.75 to 2.5 mm thick.

There are two ways to switch between the zero, span and sample gases: by using manually-operated valves or by using solenoid valves. When switching between the gases using solenoid valves, follow the instructions on valve installation in Subsection 8.3.1.

Even during automatic calibration, you can interrupt the system with the semi-automatic or manual mode of calibration. One cycle of automatic calibration is skipped, however, if the time of automatic calibration arrives when semi-automatic calibration is in progress.

    Their sealing capabilities therefore are not readily impaired. Any deterioration in these O-rings however can result in not only gas leakage but reduced resistance to mechanical vibration, which in turn may lead to reading errors. For this reason, it is recommended that the O-rings be replaced at a fixed interval (every two to three years). Consult Yokogawa for the replacement of O-rings. IM 11T03E01-51E...
