The Process Cool Down sequence reduces the water temperature before the unit shuts off to
extend the life of the pump seal. See the Program Menu section for instructions on how to enable
or disable this feature. During this sequence, the cooling valve opens and the pump runs for 120
seconds or until the temperature reaches 90°F {32°C}, whichever occurs first. During the Process
Cool Down sequence the Set Point display temporarily toggles between the target value 90°F and
current set point and the Pump, Cool, and Process Cool Down lights flash green. After the Process
Cool Down sequence is complete, the unit stops, the set point temperature displays in the Set Point
display, and the Process Cool Down light remains solid green to indicate the completion of the
sequence. Pressing the Start and/or Stop buttons during a Process Cool Down cool-down sequence
stops the sequence.
To initiate a Process Cool Down sequence on units with the Premium Controller simply press and
release the Process Cool Down button. To initiate a sequence on units with the standard controller,
press and hold the Start button, then press the Stop button and release both buttons. The Process
Cool Down sequence begins if the process supply temperature is above 90°F {32°C}.

The total accumulated pump running hours are stored for maintenance purposes. See the Program
Menu section to display the pump running hours. Running hours are in units of hundreds so a
display value of 10 means 1,000 hours. To reset the pump running hours, press the Start and Alarm
Reset buttons at the same time and hold for 3 seconds.

SPI Comm un ica t ion s (Op tio na l)

Several members of SPI : The Plastics Industry Trade Association developed a communications
standard for plastic processing equipment to communicate using the Serial Peripheral Interface
bus (SPI bus), which coincidently has the same abbreviation as the trade association. This option
includes an expansion module and a RS-485 communication port on the unit. The communication
hardware firmware is SPI 3.01 standard compliant.
To activate or deactivate this feature use the program menu Communication Type function. In addi-
tion to activating the communication type, a baud rate and SPI address must be set using the Com-
munication Baud Rate and SPI Address function. If multiple pieces of equipment are on the same
network, the base address of each machine has to be unique.
