The Process Temperature Cut-In/Cut-Out setpoints used for control are taken from the
setpoint group associated with the current Suction Pressure control group. For example,
if Suction Pressure Group 2 is currently selected for control, the Process Temperature
setpoints will also be taken from Group 2.
The following Hardware needs to be installed for the Pump Down program to function:
• Process Temperature input (Analog Channel 8) is the Alcohol Temperature
from another control system.
• The Remote Start/Stop input from DCS is used to control enabling/disabling
the process when the RMT button on the panel is used to start the process.
• Spare I/O Channel 16 will be fitted with a solid state output module to control
the Liquid Valve.
• Software for the Pump Down Program installed.
