Quo Qe Ae 000200000 TO DIAL ER ALARM 41 Linear actuator installation In a typical installation a linear actuator is physically connected to the inlets with a network of cables and pulleys These inlets are generally small and located in the ceiling walls and are usually spring loaded to aid in closing the inlet In other EE installations larger inlets may be connected to the actuator directly or with linking arm A system operates with the most precision when using the largest amount of stroke that is feasible with the actuator OPEN CLOSE In order fot the PEC to control the lineat actuator the actuator must have limit switches and a feedback potentiometer Most linear actuators are available with internal adjustable limit switches and potentiometer feedback A 10k ohm 10 turn feedback potentiometer is desired but it can range between 1k and 100k ohms Phason recommends the use of Grainger part 5A652 von Weise Fasco model V00099BA76 or equivalent DC linear actuator which can be used with a DC power supply

If the inlet has been tested and calibrated continue with these steps 1 When the inlet is controlled automatically by the PEC it is positioned according to the settings for parameter 4 and parameters 14 to 18 These parameters should be programmed so the inlet opens wider as more stages turn on In order to know what to program these parameters to adjust the inlet by pressing the UP and DOWN buttons while in manual operation and take note of the position reading for each of the desired positions The inlet should open further each time another stage turns on When the desired position reading is known the parameter can be programmed to the correct setting 10242307 27 28 Adjust the Inlet Manual Operation parameter 37 to OFF The PEC will now position the inlet automatically If the inlet begins hunting starting and stopping around the desired position the Inlet Hysteresis is set too low increase the Inlet Hysteresis adjust parameter 38 to a higher value If Inlet Hysteresis is adjusted too high the inlet will not be positioned accurately It is a good idea to decrease the Inlet Hysteresis until the inlet begins to oscillate and then increase the setting just above the point where it oscillates This will set the inlet system to operate with the most accuracy If a jam alarm occurs when the inlet 1s being positioned check to see if the inlet is stuck If it 1s not the alarm is occurring because the Inlet Time Out setting is
