Operations

5.1 Introduction

The Operations Section of this manual covers only the aspects related to safety of operating a
Triguard SC300E Safety Programmable Logic Controller configured for an Emergency
Shutdown Application.
The Operations and Maintenance Manual provided by the System Integrators will cover all
application aspects with respect to the operation of the system and all standard maintenance
procedures. All operators must be fully conversant with this manual. The supplied Operations
and Maintenance Manual will include the standard Operations and Maintenance Manual 008-
5202.

5.2 Training

All operators of Triguard SC300E Safety Systems must have completed the Triguard SC300E
Operators Training Course. It is recommended that operators be re-trained on a SC300E
refresher course every 24 months.

5.3 System Start-up

Operators must ensure that there is no dangerous material within the plant or process prior to
the start-up of the Triguard SC300E Safety System
An auditable permit to works system must be in operation before any system/process start-up
operation occurs.
Trained maintenance staff will only complete the system power-up. The Operational Start-up
procedures documented in the Operations and Maintenance Manual must be followed in the
order presented.
5.3.1

Process Loading and Start-up

Before the process is re-loaded into the plant and the process plant started, the Safety System
must be confirmed to be in full operation and 100% healthy. If during the system start-up
procedure errors still remain in the system, maintenance must ensure that these errors are
corrected before process load and start sequence commences.

5.4 System Operation

The detailed operation aspects of the supplied Safety Systems will be covered in the bespoke
Operations and Maintenance Manual supplied by the System Integrator.
The following procedures, however, must be followed to ensure the continued and safe
operation of the system and plant.

Maintenance Alarm

All maintenance alarms must be immediately brought to the attention of maintenance by
operations to enable repairs to be carried out within the specified Mean Time to Repair.
