General Theory of Operation
The AL-1000 is a high precision electronic dosing system designed exclusively for STERIS Prolystica Ultra
Concentrated Chemistries. The system will interface and dose chemistries on all STERIS equipment and competitive
washer sterilizers.
A unique microprocessor pump controller interfaces to the washer’s chemical pump power outputs and low supply
sensors via a customized washer interface module that mounts inside the washer. Service friendly electrical connectors
make washer interfacing simple and easy for the technician.
Precise speed controlled peristaltic metering pumps provide optimal accuracy for dosing of ultra concentrated
chemistries for any wash pre-programmed wash cycle. A simple calibration procedure requires calibration to 30 ML or
120 ML per minute flow rates that enable precise washer control over dosing quantities.
Since the AL-1000 dosing system is mounted remote from the washer the system includes a low supply alarm function
where with audible alarm at the system and communicated the same alarm to the washer user interface via the washer
interface module.
Bright pump signal LED’s illuminate whenever a pump signal from the washer is present. If the LED is not lit the pump
will not operate and visa-versa. Low supply sensor LED’s also indicate when the float switch on the low supply sensor
senses low level in the container.
Pumps can dose in the default “relay” mode for newer STERIS equipment or “signal” mode for all other washers.
Three pump configuration with main control, washer interface module, low supply sensors and injector kits.
