SAFETY PRECAUTIONS
1. Read and understand the user’s manual before operating the controller.
2. Inspect the controller and accessories before each use.
3. Operate the unit only under specied environmental conditions.
4. Follow instructions in the manuals for proper wiring.
5. Never connect the controller or accessories to a supply source having a voltage
greater than the maximum rated voltage of this controller or accessory.
6. Never connect the controller or accessories to a supply source having a pressure
greater than the maximum rated pressure of this controller or accessory.
7. Never use anything but clean dry inert gases or air into the
electropneumatic controller.
8. Start up sequence for electropneumatic controllers is:
a. Feedback loop must be installed and operational.
b. Electrical power should be applied and system setpoint reduced to
its lowest pressure output before turning on the pneumatic supply to
the controller.
9. Refer to product label (modication specic) for maximum inlet pressures. If
this rated pressure cannot be found, contact your local TESCOM representative
for the rated pressure prior to installation and use. Verify the designed pressure
rating of all equipment (e.g., supply lines, ttings, connections, lters, valves,
gauges, etc.) in your system. All must be capable of handling the supply and
operating pressure.
