9 Lifecycle
This chapter describes the following lifecycle phases:
Installation
Start-up
Service and maintenance
Instructions for a correct decommissioning and disposal of the products are provided in the
manuals for the individual components.
9.1 Installation
This chapter describes how to install and connect the HIMax controllers.
9.1.1 Mechanical Structure
To ensure a faultless operation, choose a suitable mounting location for the HIMax system
in accordance with the operating requirements, see Chapter
2.1.3.
Observe the instructions for the installation of Base Plates and other components in the
respective manuals.
9.1.2 Connecting the Field Zone to the I/O Module
HIMax is a flexible system designed for continuous operation. It allows the I/O modules to
be connected to the field zone:
directly, via the connector boards.
indirectly, via the field termination assemblies.
The following section describes the four recommended wiring variants.
1. Connection to single connector boards with screw terminals
2. Connection to redundant connector boards with screw terminals
3. Connection to single connector boards via field termination assemblies and system
cables.
4. Connection to redundant connector boards via field termination assemblies and system
cables.
Additional wiring options require higher planning efforts and are not described in the
manuals. If required, HIMA recommends to contacting HIMA's experts in the Project
Management & Engineering division.
Wiring 1
For an individual I/O module, connect the sensors or actuators to a non-redundant
connector board with screw terminals.
Connect individual sensors or actuators to an individual I/O module on a per channel
basis (non-redundant).
Connect two or more redundant sensors or actuators to two or more redundant modules
on a per channel basis. The number of redundant sensors or actuators must be identical
with the number of redundant modules (e.g., two sensors/two modules).
