__________________________ MODEL 2234 DIGITAL FLOW COMPUTER

3.4.4 INDICATORS

Indicators other than the keyboard and LED display consist of three status
indicators and an optional six-digit electromechanical counter on the front panel.
The three colored status indicators show the status condition of the total system.
The red indicator is ON when an out-of-tolerance (error) condition exists (e.g., a
transmitter over-ranges) and is OFF when the condition ceases to exist.
The amber indicator is ON when the out-of-tolerance condition, which causes the
red indicator to light, is entered by the computer into the error memory list. The
amber indicator remains lighted until all error conditions have ceased and the
operator has cleared the error memory list as described in paragraph 3.7.2.
The green indicator is ON when the operator entry "enable/disable" switch on PC
Board No.1 is in the "enable" position. The green indicator being ON indicates
that the operator can enter or alter any of the respective measurement parameters
when the operator entry "enable/disable" switch, in the "disable" position, causes
the computer to display ENABLE at any attempt by the operator to enter or alter
the measurement parameters.
The operational six-digit electromechanical counter on the front panel displays the
gross, net, or mass flow total that is selected during the Startup Prompting
Sequence.
