Removal and Replacement Procedures - Overview

Removal and Replacement Procedures

Overview

This section contains procedures for removing and replacing the active components of an HC900 Hybrid Controller. It also includes recommendations, suggestions, and hints as they apply to the circumstances under which the procedures are used.

Safety Considerations - PLAN AHEAD!

When using the procedures in this section, plan the sequence of procedural actions so as to ensure:

The safety of personnel

The protection of property

The integrity of operating processes

The first consideration is safety of personnel. While there is always an inclination to preserve the materials and time invested in a running process, no action should ever be taken that would risk injury to personnel.

Protection of personnel property is an important consideration that always requires comprehensive knowledge of the entire control process: the control equipment, the process control strategy, and the conditions and circumstances that exist when the removal and replacement procedures are taken.

The procedures in this section include notices of potential hazard as they apply to various components in the controller. Because each control process and the set of conditions and circumstances at each user site are unique, it is the user's responsibility to know the potential consequences of each action as it relates to a running process.

It is recommended that the user becomes familiar with the significant aspects of each set of circumstances and has a plan for execution of the proper action sequence.

All of the input/output modules available for use in the HC900 Controller have a RIUP designation. That is, they can be Removed and Inserted Under Power, where "power" refers to DC power at the backplane of the rack. (It does not refer to power for field wiring at the terminal board associated with the I/O module, which must be disconnected (using a user-supplied switch) at the field device before removing or inserting the module.

For all other components of the controller, AC power to the controller must be removed before removal or replacement of the component.

Hazardous voltages exist at the Power Supply and at the terminal boards on I/O Modules

Only trained and authorized personnel should perform the procedures in this section.

Disconnect all sources of power associated with these components before removal or insertion.

Failure to comply with these instructions could result in death or serious injury.
