Setpoint Rate/Ramp/Soak Program Operation
5/00 UDC3300 Expanded Model: DC330E User Manual 57
4.4 Operating Modes
The controller can operate in any of three basic modes:
• Manual – One or Two Loops
• Automatic with Local Setpoint – One or Two Loops
• Automatic with Remote Setpoint – One or Two Loops
• Manual Cascade
• Automatic Cascade
4.5 Setpoints
You can configure the following setpoints for the UDC 3300 controller in the control
group.
• A single local setpoint (SP)
• Two local setpoints (SP, 2SP)
• One local setpoint and one remote setpoint (SP, RSP)
• Three local setpoints (SP, 2SP, 3SP)
• Two local setpoints and one remote setpoint (SP, 2SP, RSP)
Changing Local Setpoint 1, 2 or 3
To scroll through the setpoint type menu, press and hold in the SETPOINT SELECT
key. Release when the desired active setpoint selection is displayed.
ATTENTION
“KEY ERROR” will appear in the lower display if:
• You choose either local setpoint 2 or 3 or remote setpoint and your choice has not
been configured as the setpoint source.
• You attempt to change the setpoint while a Setpoint Ramp is enabled.
• Setpoint Ramp rate will apply to Local SP changes, if enabled.
After changing a local setpoint value, if no other key is pressed, a minimum of 30
seconds time will elapse before the new value is stored in nonvolatile memory. If
power is removed before this time, the new setpoint value is lost and the previous
setpoint value is used at power up. If after changing the LSP value another key is
pressed, then the value is stored immediately.
