Start-up Procedure
Tools Required: AC Voltage Meter, Standard Hand Tools, Amperage Meter
Start-up Procedure - Fans
1. Check all electrical connections are secure and tight.
2. Inspect the blades and air-stream for obstructions.
3. Compare the supplied voltage with the fan’s nameplate voltage. If this does not match, correct the
problem.
4. Discard any loose tags or covers attached to the unit. If the yellow sticker is attached to the unit, it can
remain in place.
5. Start the fan up by turning the external disconnect/control to the ON position. Shut it OFF immediately
to check rotation of the fan. Normal direction should be counter-clockwise as viewed from below the
fan. For 3-phase motors, any two power leads can be interchanged to reverse motor direction. Some
control packages allow for fan rotation reversal.
6. When the fan is started up, observe the operation and check for any unusual noises.
7. Switch the external disconnect back to the ON position.
8. Measure and record the voltage and amperage to the motor and compare with the motor nameplate
to determine if the motor is operating under safe load condition.
Start-up Procedure – Smart Control
Once all required connections have been completed as indicated on the installation schematic, start-up
can begin.
Apply power to the panel. The ECPM03 board and the HMI will power up and illuminate. If that is not the
case, check all power connections. Verify that there is no alarm message displayed on any HMI screen. If
there are alarms present, you can press the MUTE button to silence the alarm and then work to resolve
them. The HMI has 3 main modes: AUTO mode, Manual Mode, and Building Management Mode. The HMI
has 4 buttons; the function is displayed adjacent to them on the screen. These functions will change
depending on the status of the panel. If no text is adjacent to the button, it does not have a function.
Typically, the control operates in AUTO mode. In this mode, individual buttons are locked out and fans
operate based on the room temperature.
In MANUAL mode, there are typically four functions shown. The 2 left buttons control the speed of the fan
(SPEED UP and SLOW DOWN). The bottom right button controls the fan direction. The top right button
turns the fan on and off.
The status of those elements is shown by the shading used inside the box associated with the function. An
empty box around the FAN function means that the FANS are turned OFF. A dark box around the FAN
function means that the FANS are turned ON. For HVLS, this also applies to the FORWARD/REVERSE
button. The text on the HMI shows the action that the button will produce.
NOTE: The term button will be used to refer to either the actual button or the function associated
with it.
