Operation and Maintenance Manual
Rev: L13
General Guidelines
Proper installation and use of the BECSys controller depends on the specific needs of the application. Read the manual
completely before starting the installation and ensure all guidelines and recommendations are followed. All components
should be mounted and the flow cell plumbing installed and pressure tested before wiring the controller. Ensure
compliance with all applicable plumbing and electrical codes during the installation as well.
Firmware Version
This manual was written for firmware v1.54. If you received newer firmware but did not receive a copy of the manual
covering that version of firmware, please contact your distributor.
Environmental Conditions
The BECSys5 is housed in a NEMA 4X (IP65) enclosure. It should not be used in explosive environments. The
BECSys5 should be mounted so that adequate ventilation is provided around the enclosure, preventing general
environmental specifications from being exceeded (see table below).

ports must be sealed using hardware rated NEMA4 or better. Damage to the controller caused by improper
sealing of the enclosure is not covered under warranty.
