5 — Operating Instructions

11971394_D Automatic Load/Unload System (ALUS) Operator Manual

Operating Instructions

5.1 Changing Operation Configuration

Summary: The sterilizer can be configured with or without an Automated Load/Unload System (ALUS). Alternately, the

sterilizer can be configured to be loaded manually, but use an ALUS table for automated “Unload Only.”

NOTE: Customers using only the UNLOAD portion of ALUS need only refer to the applicable unload content. When ALUS is used

for unload only, loading is performed using the typical transfer carriage method, as discussed in the sterilizer operator manual.

Sterilizer Operation with ALUS

The sterilizer provides the hardware and software interface for Automatic Load/Unload (or Unload Only) equipment to

control the automatic loading and unloading process for sterile cycles.

• When the sterilizer is configured with ALUS from within service mode, the sterilizer automatically loads loading

carts from the loader (if applicable) and starts sterilization cycle selected by the operator.

• The sterilizer completes the sterile cycle and automatically unloads the loading cart from chamber when:

> Sterile cycle has not been aborted

> An alarm has not occurred, and

> No loading cart is present on the unload table.

NOTES:

1. ALUS “Unload Only” systems only function with sterile cycles. They are disabled when test cycles are selected.

2. Reference the sterilizer operator manual for information regarding manually loading a sterilizer.

Sterilizer Operation without ALUS

The Automatic Load/Unload System (or Unload Only System) may not always be needed. If this is the case, turn OFF

the Automatic Load/Unload System (or Unload Only) from Machine Setup (from within the Options Mode).

NOTE: When ALUS System has been turned OFF, sterilizer load/unload inputs and outputs are non-functional and the

automatic load/unload equipment is not controlled by the sterilizer.

5.2 ALUS Control System

General

The automatic load/unload system has been developed to simplify the work in, for example, the central sterilization

department. The system's main function is to load and unload baskets racks with sterile goods from a sterilizer.

The loading process is controlled from the sterilizer. The load/unload system automatically switches on and off when

the sterilizer is switched on and off.

(B) - Manual/auto mode Turn key to select automatic or manual mode. In manual mode, the four arrows light up.

(D) - Confirm loading button Push confirm loading button when loading of the loader is complete.

(E)- Emergency stop button To stop ALUS system quickly in case of emergency.

Interface Box

The ALUS interface receives and sends signals to govern proper automatic loading and/or unloading of an ALUS-

equipped sterilizer, regardless of whether the associated sterilizer is single or double door. Refer to Section 5.7, Pass

Through Cycle (Double-Door Units) for related information.

ALUS Loader – Automatic Mode

In automatic mode the loading/unloading is controlled from the sterilizer.

Loading - Put a normal load on the loading table. Load advances into sterilizer chamber when sterilizer is ready (i.e.,

previous cycle and unloading are complete).

Unloading is controlled from the sterilizer. (Cycle completes, load unloads.)

ALUS Loader – Manual Mode

Loader/Unloader functions can be manually operated. Set key switch to "Manual." All table movements can then be

operated from directional push buttons located on the load/unload table.

NOTE: While in manual operation mode, all ALUS control buttons are illuminated.

IMPORTANT: Return loader/unloader to stand-by (Start) position before restoring to automatic mode.

1. Return table to "Start." Use manual mode and manual push buttons.

5 — Operating Instructions

11971394_D Automatic Load/Unload System (ALUS) Operator Manual

2. Return load/unload tables to automatic operation by setting key switch to “Automatic”.

Verify Emergency Stop

When pushed, an Emergency Stop button (one located on each of the side of loader and unloader) interrupts supply

power to the loader/unloader and signals the PLC. To ensure the Emergency Stop System works:

1. Press emergency stop when running ALUS.

2. Verify the Loader/Unloader stops.

3. Restore Emergency Stop.

4. Ensure load/unload system is not running.

5. Press yellow (reset) push button portion (of Emergency Stop) to restore operation mode.

6. Turn key switch to manual position.

7. Return loader/unloader to the stand-by (start) position.

8. Turn key switch to automatic mode.

NOTE: The yellow outer edge portion of Emergency Stop button is the Emergency Stop Reset. It is used to reset ALUS

following an emergency stop scenario. The Confirm Loading button (lower left of button control) illuminates when the

loader is operational.

Power Limit – Current Limitation Card

ALUS loader and unloader motors are connected to “current limitation cards.” In case of overload, for example, from

obstruction to feeder movement, a limitation card turns off the overloaded motor, making the table incapable of

automatic movement. If this occurs, the manual mode must be used to restore ALUS to the start position, before

automatic mode can resume.

Safety

WARNING

PERSONAL INJURY HAZARD

All Equipment involving mechanical movement can cause injuries. Never use hands to stop movement of

loaders or unloaders. Keep clear of loader/unloader during operation. Be alert to use Emergency Stop

buttons if needed.

To prevent jeopardizing built-in system safety, it is important to avoid removing parts or replacing components with

other that factory original or authorized equivalent.

If a component is removed or replaced, or if the ALUS system undergoes unauthorized reprogramming, the warranty is

violated and the manufacturer is no longer responsible.

In event of damage and/or and injury, report the incident to STERIS as soon as possible.

For safety, an Emergency Stop button is located on each of the side of loader and unloader. When pushed, supply

power to the loader/unloader is immediately interrupted.
