2. DISPLAYS AND OPERATIONS
2.1 Front Panel Description
①
Upper display window, displays PV, parameter code, etc.
②
Lower display window, displays SV, parameter value, or
alarm code.
③
Setup key, for accessing parameter table and conforming
parameter modification.
④
Data shift key, and also for auto tuning, auto/manual switch.
⑤
Data decrease key, and also run/pause switch
⑥
Data increase key, and also stop key
⑦
LED indicator. PRG indicator is non-applicable for AI-519.
The lighting of MAN means in manual output status. MIO, OP1, OP2, AL1, AL2, AU1 and AU2 indicate I/O operation
of the corresponding module. For example, That the COMM indicator is lighting means that the instrument is
communicating with upper device.
Basic display status :
When power on, the upper display window of the instrument shows the process value (PV), and
the lower window shows the setpoint (SV). This status is called basic display status. When the input signal is out of the
measurable range (for example, the thermocouple or RTD circuit is break, or input specification sets wrong), the upper
display window will alternately display “orAL” and the high limit or the low limit of PV, and the instrument will automatically
stop output. If the lower display window alternately display “HIAL”, “LoAL”, “HdAL” or “LdAL”, it means high limit alarm,
low limit alarm, deviation high alarm, and deviation low alarm happening. The alarm display can also be turned off by
setting parameter AdIS to oFF. If “EErr” is displayed, it means internal self-test error, and the instrument should be sent
back for repair.
