Honeywell UDC2500 manual SP Ramp Set Up Group, Ti Min

Configuration

3.5 SP Ramp Set Up Group

Introduction

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 RUN/HOLD 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.
