3.12 SP Ramp Set Up Groups
The Setpoint Ramp 1 or 2 Set Up groups let you configure two setpoint ramps. Each group (SP RAMP1
and SP RAMP 2) can be configured one of three ways: ramp, rate, or setpoint program.
Setpoint Ramp
Setpoint will ramp between the current local setpoint and a final setpoint over a time interval (SP RAMP).
Setpoint Rate
The Setpoint Ramp Set Up group also contains the function parameters that let you configure a specific
ramp rate up and ramp rate down (SP RATE). These rates are used when the local setpoint is manually
changed.
Setpoint Program
Also included under this group are prompts for configuring a Setpoint program (SP PROG). The prompts
and instructions for Setpoint programming are presented in the
Section 6 - Setpoint Ramp/Soak
Programming Option.
Function prompts
Table 3-9 lists all the function prompts in the SP RAMP 1 or SP RAMP 2 Set Up group. Configure each
ramp separately. When you enable the ramp type (SP RAMP, SP RATE, SP PROG) the other two types
are hidden from the display.
