Initial Start-Up
c1. _____ Open all doors on the booth c2. _____ Confirm incoming voltage matches unit name plate (on inside door of control panel) before energizing disconnect (energize after confirmation)
c2a. L1 to L2: _______________
c2d. L1 to Ground: ________________
c2b. L2 to L3: _______________
c2e. L2 to Ground: ________________
c2c. L3 to L1: _______________ c2f. L3 to Ground: ________________ c3. _____ Confirm voltage between terminal 2 and 1B (approx. 120vac) Voltage Reading: _______ c4. _____ Confirm voltage between terminal 2 and 1A (approx. 120vac) Voltage Reading: _______ If there is no voltage on 1A, then check fire suppression system. If fire suppression system is not present, install jumper between 1A and 1B (de-energize panel first). c5. _____ At the remote control panel, ensure the E-stop button is pulled out. c6. _____ At the remote control panel, on the GA-1 device, measure the DC voltage before plugging in the “telephone cable” c6a. Terminal 2 to Terminal 1 = +24 to +36 VDC (proper polarity is critical) c6b. Terminal 2 to Terminal 3 = +2 to +3 VDC (proper polarity is critical) c6c. Terminal 2 to Terminal 4 = +2 to +3 VDC (proper polarity is critical) c7. _____ After DC voltage has been confirmed correct, plug in the “telephone cable” – the display should illuminate and show the home screen. c8. _____ Adjust “booth pressure set point” to -0.099 (see step a12 screen 4) which will force the exhaust VFD to ramp to 60hz (full speed). c9. _____ Set mode to “summer” (this will prevent the burner from attempting to ignite) c10. _____ Set spray temperature to 50F c11. _____ At the AMU control panel, turn on SW5 – the inlet/discharge damper should open (damper can be located at inlet or discharge of AMU) c12. _____ Visually inspect the damper to ensure it opens fully (if actuator is not tight, the actuator will open and prove, but the damper may remain closed). c13. _____ After the damper is proven open, the AMU fan and exhaust fan(s) will begin to rotate. c14. _____ Visually confirm AMU fan is rotating in the correct direction (arrow on the fan housing) c15. _____ Visually confirm exhaust fan(s) is rotating in the correct direction (arrow on the fan housing) c16. _____ Confirm AMU fan is running at 60.00hz (supply VFD) c17. _____ Confirm AMU fan is not exceeding FLA rating when running at 60.00hz Press “set” button on the VFD to display amps. Compare reading to AMU motor name plate from step b11c. c18. _____ Confirm exhaust fan(s) is running at 60.00hz (exhaust VFD) c19. _____ Confirm exhaust fan(s) is not exceeding FLA rating when running at 60.00hz Press “set” button on the VFD to display total amps. Compare reading to exhaust motor name plate from step b6c. If there is more than one exhaust fan, use a true RMS ammeter to measure the amps at the output side of the exhaust fan overloads. c20. _____ If the unit has exhaust overloads, ensure they are set to match the FLA rating on the exhaust motor name plates from step b6c. c21. _____ Confirm VFD parameter P9 is set to match total FLA rating of exhaust motor(s) Example 1: if there is 1 exhaust motor rated for 7.2 amps, ensure P9 is set for 7.2 Example 2: if there are 4 exhaust motors, each rated for 7.2 amp, ensure P9 is set for 28.8
