3.1 Symbol identification DANGER! Potentially lethal voltages. The CE mark proves the compliance of the product with the requirements of the directives. 3.2 Types / article numbers This User Manual covers the following products: 931U‐C9C7C‐BC Signal Conditioner 931U‐CABLE Programming Cable 3.3 General description / applications / examples The 931U‐C9C7C‐BC is an accurate and stable signal converter / isolator / alarm generator for use in measurement and control systems.
Typical Applications Typical of applications for the 931U‐C9C7C‐BC is the conversion of thermocouple temperature input (low range of millivolts) into a high level (e.g. 4‐20 mA) value for transmission to a control system. In this type of installation the 931U‐C9C7C‐BC pro‐ vides: • Linearization of the standard thermocouple temperature/millivolts characteristic. • Isolation of the input signal to the control sys‐ tem.

5.1 General (Competence Warning) The 931U‐C9C7C‐BC should only be installed by technically qualified personnel with sufficient quali‐ fication or knowledge in the subject of instrumenta‐ tion and control engineering. 5.2 Mounting / Environmental / EMI protection / warm up Mounting 931U‐C9C7C‐BC is designed to be mounted onto a TS35 DIN rail. It clips onto the rail via a spring‐loaded mounting foot, and can be removed via a spring release on the edge of the product near the mounting rail.
When auxiliary power is switched on, for the first 200 ms the 931U‐C9C7C‐BC will consume up to 200 mA. 5.3 Electrical Connections Input, output and power supply wiring is made via numbered, pluggable connectors, which may be screw clamp or tension clamp type, depending on the item article number. The connectors are coded to prevent the power supply connector being fitted in the wrong position.

The green Status LED is flashing It indicates sensor wiring (short circuit or open cir‐ cuit) or internal fault. See description in chapter 3 to identify fault source. 17H The DC output is incorrect 1 Ensure the input type and range are configured as required and wiring connections are correct. 2 Check the output configuration settings for cor‐ rect range and transfer functions including direct or re‐verse action.
