Operation
Regulator Adjustment
Controlled outlet pressure settings are obtained using TESCOM™ pressure reducing regulators
by adjusting the screw. Rotating the adjustment screw clockwise raises the outlet pressure
while a counterclockwise rotation coupled with venting of the downstream side of the
regulator plumbing lowers the outlet pressure. Final adjustments should be made in the
direction of increasing pressure to obtain the most accurate set point.
TESCOM™ regulators will operate with any liquid or gaseous media compatible with the
wetted materials.
Heater Temperature Controller Status
RED LED on the heater controller printed circuit board helps to shows that there is NO
power to the controller when the LED stays off. See Figure 5.
•
When LED is flashing, there is power to the controller and the heater.
•
When the LED stays on without flashing, there is an error:
*Temperature feedback is out of range
*Temperature set-point is out of range
*Temperature feedback lag. The feedback has been unable to meet the set-point value.
Heater temperature feedback is provided with a 4-20mA signal. The 4-20 mA output
correlates to a thermocouple temperature reading of 50 to 400 °C / 122 to 752 °F.
