Axiom Relay Contact Outputs:
When equipped with the optional RS-232 contact kit board, Labconco Axiom Biosafety
Cabinet (BSC) models are provided with two (2) dry relay contacts to allow connection
to an external monitoring system, or to switch other air handling units “on” when the
Labconco unit is turned on.
With the optional RS-232 board installed, the Labconco Axiom BSC provides two
contacts: One to indicate the internal Labconco blower is on, (so that external blowers
may also be energized) and the other to indicate airflow errors. These contacts
provided will “short circuit” when the blower is turned on, or when there is an airflow
error. This means that the Labconco contacts are isolated from the Labconco
equipment, and the user must provide the interface circuitry based on the requirements
of the connected equipment.
The dry contacts are accessed at connector J3 of the Axiom Control Box (Labconco
harness P/N 3432300 is available for easy connection). This J3 connector is located on
the electrical control box on top of the BSC, above the “ALARM CONTACT” label as
shown in the picture below:
