SERVICE MODE DESCRIPTION
2.0 SERVICE MODE DESCRIPTION
The MRidium 3860+ is configured with a Service Mode that allows technicians
to access the software diagnostic subsystem. Once the Service Mode is
enabled, the technician can use the diagnostic test sequences to verify
operation of the operator interface features, to operate the pumping
mechanisms independent of the alarm/malfunction interrupts, to check Analog
to Digital voltages and to access the history log. Additionally, the Service Mode
is used to test the serial port, configure the instrument's radio communication
interface and select one of the six available languages for the user interface
presentations (when available).
Put Pump into Service Mode by Press overlay KeyPad On (I) button and the
holding the overlay KeyPad Cancel key depressed until the Service Mode is
displayed. Once enabled, Maintenance Mode operation is strictly software
dependent.
The Channel B Start/Stop key changes the pump from SERVICE MODE A
(main 3860+ pump) to SERVICE MODE B (3861 SideCar pump).
