DISPLAY AND OPERATIONS 

 

Upper display window, displays PV, 
parameter code, etc. 

 

Lower display window, displays SV, 
parameter value, or alarm 

 

Setup key, for accessing parameter 
table and conforming parameter 
modification. 

 

Data shift key, and auto tuning. 

 

Data decrease key 

 

Data increase key 

 

LED indicator.  MAN, PRG, MIO, 
COM, OP2, AL2, AU1 and AU2 
Com indicators is non-applicable. 

 
OP1 and AL1 will indicate I/O operation of the corresponding module.

 

 

 

Basic display status:   

When power on, the upper display window of the instrument shows the process 
value (PV), and the lower window shows the set-point (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.
