EA402 913-402-000-012 is installed as a controlled cable segment, so the physical route has to preserve the coaxial path from the TQ4xx probe to IQS900.

1. 01

   Minimum bend radius

   The bare cable route for EA402 913-402-000-012 keeps at least 20 mm bend radius; the optional hose route uses the separate 50 mm value.

2. 02

   Connector orientation

   Seat the self-locking miniature coaxial connector of EA402 913-402-000-012 into its matching TQ4xx/IQS900 connection before securing the route.

3. 03

   Thermal route

   The cable and connector limits for EA402 913-402-000-012 are evaluated with the selected probe, protection and environmental variant.

The extension is a measurement-path component; installation details determine whether the signal reaches the conditioner as the selected TQ4xx system.

1. 01

   Do not mix cable types

   EA402 913-402-000-012 uses the EA402 FEP coaxial construction; a general instrument lead does not provide the same cable function.

2. 02

   Account for total length

   When EA402 913-402-000-012 is added, include the TQ4xx integral cable in the total 1 m, 5 m or 10 m system arrangement.

3. 03

   Use the protection option correctly

   If an IP172 interconnection protector is specified with EA402 913-402-000-012, its connector and environmental position remain part of the same cable path.

EA402 913-402-000-012 occupies the middle of the TQ4xx measurement chain, joining the front-end cable to the conditioner rather than creating a separate field signal.

1. 01

   Probe side

   The integral cable from TQ402 or TQ412 reaches the EA402 913-402-000-012 extension segment.

2. 02

   Conditioner side

   The far connector of EA402 913-402-000-012 continues to the IQS900 high-frequency input.

3. 03

   Measurement output

   IQS900 conditions the proximity signal after the path containing EA402 913-402-000-012; the cable itself is not the controller output stage.

The TQ4xx system uses defined cable combinations, so EA402 913-402-000-012 is selected together with the probe and conditioner path.

1. 01

   System length

   The TQ4xx integral cable and EA402 913-402-000-012 extension together make the specified 1 m, 5 m or 10 m system length.

2. 02

   Environment code

   For an Ex arrangement, the selected EA402 variant, probe and conditioner environment must describe the same installed path around EA402 913-402-000-012.

3. 03

   Protection position

   An optional IP172 protector can sit at the interconnection involving EA402 913-402-000-012; it does not change the role of the EA402 extension itself.
