Service Operations; Resetting A Circuit Breaker - Labconco Cell Logic+ B2 User Manual

Service Operations

The operations in this section provide instructions to maintain the Cell Logic+ Type B2
for normal consumable replacement, and access to parts in accordance with the
Recommended Maintenance Schedule. This section does not cover service operations
beyond normal maintenance, nor does it cover annual airflow certification procedures.
These advanced sections are found in the Logic+ Technical Manual.

Resetting a Circuit Breaker

Should an over current situation arise during normal operation, the circuit breakers
located on the left side of the top electrical box will trip, protecting the cabinet from
damage.
The Cell Logic+ Type B2 biosafety cabinet offers internal outlets to power small devices
inside the cabinet. The internal outlets are protected by one circuit breaker (two circuit
breakers on 230v models), and the cabinet electronics are protected by different circuit
breaker (two different circuit breakers on 230v models). This allows the cabinet to
continue to operate, providing protection to the product and user, should a device
connected to an internal outlet experience an over current situation.
If the internal outlets do not have power when the Outlet icon is displayed on the Home
Screen, reset the appropriate circuit breaker(s) as shown in Figure 8-1. The outlet
circuit breaker(s) are in the Rear Position(s).
If the cabinet does not have power when the System Reset Switch (Figure 7-2) is on,
reset the appropriate circuit breaker(s) as shown in Figure 8-1. The cabinet circuit
breaker(s) are in the Front Position(s).
The thrown circuit breaker will be easy to identify, as the white barrel will be extended
further than the other circuit breaker(s). To reset, simply push it in.
