This chapter describes how to install, configure and connect the module. For more
information, refer to the Safety Manual (HI 801 003 E).
i
The safety-related application (SIL 3 in accordance with IEC 61508) of the inputs and the
sensors connected must comply with the safety requirements. For more information, refer
to the HIMax Safety Manual.
4.1 Mounting
Observe the following points when mounting the module:
ƒ Only operate the module with the appropriate fan components. For more information,
see the System Manual (HI 801 001 E).
ƒ Only operate the module with the suitable connector board. For more information, see
Chapter 3.6.
ƒ The module and its connected components must be mounted to provide protection of at
least IP20 in accordance with EN 60529: 1991 + A1: 2000.
NOTE
Damage due to incorrect wiring!
Failure to comply with these instructions can damage the electronic components.
Observe the following points:
ƒ Plugs and terminals connected to the field zone.
-
Take the appropriate earthing measures when connecting the plugs and terminals to
the field zone.
-
Use shielded cables with twisted pairs.
-
Connect one twisted pair of the shielded cable to each of the analog measurement
inputs.
-
On the module side, the shielding must be connected to the cable shield rail (use
SK 20 shield connection terminal block or similar).
-
When using stranded wires, HIMA recommends fastening ferrules to the wire ends.
The terminals must be suitable for fastening the cross-sections of the cables in use.
ƒ If the transmitter supply is used, use the one assigned to the input, e.g., S1+ with AI1+.
ƒ HIMA recommends using the transmitter supply of the module.
Failure of an external supply or measurement unit can lead to overload and damage of
the affected measurement input on the module.
If an external supply is used for the given application, check the zero and final values
following a non-transient overload!
ƒ The inputs may be wired redundantly using the corresponding connector boards, see
Chapter 3.6.
4.1.1 Wiring Inputs Not in Use
Inputs that are not being used may stay open and need not be terminated. However, to
prevent short-circuits, never connect a wire to a connector board if it is open on the field
side.
