Honeywell VRX180 Manuale Utente

Each profile can monitor up to 2 process variables.  The second PV is for monitoring a second variable 
related to your process.  The value of each PV is compared with the value of the profile.  If the 
difference between either PV and the profile value exceeds specified amounts, the profiler will Hold 
(soak), if enabled to do so. 

Up to 63 segments may be in a profile. 

All segments use the same time base (seconds, minutes, or hours). 

There are four ramp types selectable at the RAMP TYPE prompt. 

1. Value/Duration 

2. Time 

3. Rate 

4. External 

Value/Duration (Val/Dur)Ramp Type 

This is the only ramp type that allows consecutive ramps or soaks.  VALUE is the beginning value of the 
segment; TIME is the time needed to reach the VALUE of the next segment.
