9. DIGITAL TEMPERATURE CONTROLLER
9 DIGITAL TEMPERATURE CONTROLLER
The PH Series has three Digital Temperature Controllers to manage the temperatures for
the Primary Heaters (Iso (A), Poly (R)) and the Heated Hose. The Hose Heater Controller
is programmed different from the Iso (A) and Poly (R) Controllers and therefore not inter-
changeable with them.
WARNING! Do not turn the Temperature Controllers ON
until the Proportioner Purging procedure is complete and the
Primary Heaters and Heated Hoses are filled with material.
EATON CONTROLLER
1. Ensure Main Power (See Figure 6 on page 15) is ON, Control Power (See Figure 6 on
page 15) is ON
and 01 Display light is lit.
2. Press and release X button. The display will read SP1.
3. Press and release up or down button to display the current material
temperature set-point.
4. Press and hold the up or down button to increase or decrease the
material temperature set-point to the desired value as determined by
the material supplier or application conditions.
5. Press and release up and down together to return to the actual material
temperature in the Primary Heater/Hose Heater.
NOTE! The Temperature Controller normally displays the ac-
tual material temperature. When lit, the “01” display in the
upper left indicates power is sent to the designated heating
system. The “01” display goes out when the material temper-
ature has reached its set-point. The “01” display will continue
to cycle on and off indicating the Controller is maintaining the
material temperature set-point.
