Ramping Function
Select when the controller will ramp. Ramping limits the speed at
which an element can heat up. Ramping is often used to protect parts that
would crack or warp if they heat up too quickly.
• [`OFF] sets the system to heat as quickly as possible.
• [Strt] sets the system to ramp only at startup.
• [StPt] sets the system to ramp at startup and whenever the set point
changes.
[``rP] This prompt appears only on controllers with [`rSP] (Input Menu)
set to [`OFF] and with [`Ei1] not set to [`rSP] and with [CntL] (Global
Menu) not set to [diff] or [rati].
