Warning: The ORP and pH Sensors are very fragile and must be handled with care. The tips of the probes must be kept wet at all times, requiring the wetting caps to remain in place until they are ready to be installed. The probes must be stored in temperatures above freezing.
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 v1.26. If you received newer firmware but did not receive a copy of the manual covering that version of firmware, please contact your distributor.

It should not be used in explosive environments. The BECSys7 should be mounted so that adequate ventilation is provided around the enclosure, preventing general environmental specifications from being exceeded (see table below).
Environmental Specifications Specification Rating Storage Temperature -40 to 85 Deg C Ambient Operating Temperature -18 to 50 Deg C Ambient Humidity 95% non condensing maximum humidity
Electrical Specifications The BECSys7 may be ordered in either a 115VAC model or a 230VAC model. Following are the electrical specifications for each model:
115VAC Model: Voltage: 115VAC 60Hz Phase: Single Current: 32.5 Amps Full Load (½ Amp – Controller) (32 Amps – Relay Outputs: 3A X 8, 8A X 1)
