Honeywell UDC2500 ユーザーズマニュアル

Set Point Ramp, Set Point Programs and Set Point Rates can be configured in this group. 

A single Setpoint Ramp [SP RAMP] can be configured to occur between the current local 
setpoint and a final local setpoint over a time interval of from 1 to 255 minutes.  

A Set Point Rate [SPRATE] lets you configure a specific rate of change for any local 
setpoint change. 

A single Set Point Program [SP PROG] with up to 12 segments can be configured. 

For more information on Set Point Rate, Ramp and Programming, see Sections 4.18 
through 4.21. 

You can start and stop the ramp/program using the 

 key. 

PV Hot Start is a configurable feature and means that, at initialization, the setpoint is set 
to the current PV value and the Ramp or Rate or Program then starts from this value.
