Mechanical WARNING: DO NOT LIFT CONTROL BY WIRING COMPONENTS Site Preparation 1. Provide clearance around installation site to safely install equipment into its final position.
Wall Mount Installation (Optional) Mount control panel with adequate clearance from excessive heat sources such as appliances to prevent damage of the components. Duct Sensor Installation When the control panel is ordered, the system typically consists of one duct sensor per hood exhaust riser. These sensors are typically shipped factory installed in factory assembled hood risers. If the risers are field cut, the sensor and other components are shipped loose for field installation as shown below.
Electrical Before connecting power to the control, read and understand this entire document. As-built wiring diagrams are furnished with each control by the factory and are attached either to the door of the unit or provided within a paperwork pouch internal to the panel. Electrical wiring and connections should be done in accordance with local ordinances and the National Electric Code, ANSI/NFPA70.
Low Voltage Wiring Low voltage field wiring consists of Duct and Room Temperature sensors, ECM motors, 0-10VDC output, 24VDC input, or Modbus communication over CAT-5 cables for HMI(s) and remote equipment. Additionally, panels can be ordered with Building Management Options. Refer to the Building Management Owner’s Manual, if equipped, for low voltage building management wiring requirements.
Variable Frequency Drive (VFD) Installation Instructions Input AC Power 1. Circuit breakers feeding the VFDs are recommended to be thermal-magnetic and fast acting. They should be sized 1.25 to 1.5 times the input amperage of the drive. Refer to the installation schematic for breaker sizing. 2. Each VFD should be fed by its own breaker. If multiple VFDs are to be combined on the same breaker, each drive should have its own protection measure (fuses or miniature circuit breaker) downstream from the breaker.

OPERATION Start-Up Procedure NOTE: FIRE system must be in ARMED state before proceeding. 1. Once all required connections have been completed as indicated on the installation schematic, startup can begin. Apply power to the panel. The ECPM03 board and the HMI(s) will power up and beep. If that is not the case, check all power connections. Verify that there is no alarm message displayed on any HMI. If there are alarms present, you can press the MUTE button to silence the alarm and then work to resolve them.
6. If the controls include the Self Cleaning or CORE Protection Fire System option, a WASH button will be displayed on the HMI. Push the button to start the wash cycle. Water will be sprayed in the plenum and duct of the hood and surfactant will be injected at a predetermined frequency. The wash cycle will stop when the wash timer expires or when the Stop Wash button is pressed. Make sure Hood filters remain in place during the wash cycle.
Max Air Flow: By manually pressing the MAX AIR button, the fans will run at High Frequency, typically 60 Hz for a factory set time of 30 minutes. This time is adjustable under the Misc Options section of the configuration menu. Once the time period has expired or if the MAX AIR button is pressed again, the VFDs will go back to operating based on the duct temperature.
Functionality Fan Control The control panel controls fans through VFDs. They are used to adjust the speed of 3 phase motors and frequency is proportional to airflow. There is one VFD for each fan in the system. Preparation Time Mode 1. This option is enabled by default from the factory. It can be disabled under Configuration → Factory options. 2. Preparation Time Mode is available for morning operation when appliances are off or when very light food preparation is performed.
If the signal from the make-up air is not received by the DCV 90 Sec (factory default) after the start signal is sent to the supply fan, an alarm will appear on the HMI. The DCV panel ships with a jumper between terminals IL1A and IL1B for supply #1 and IL2A and IL2B for supply #2 if present. The jumper has to be removed first before wiring the interlock from a make-up air unit.
The amount of time elapsed since the previous wash cycle is greater than the “Wash Min Interval time” value configured under “Misc Options”. That elapsed time is reset to zero when the wash cycle is run. c. If a Building Management System (BMS) is remotely controlling the fans through the external input terminal IO1, when the Fans are turned ON and then OFF through the IO1 terminal, granted that the fans are not maintained on by the duct temperature sensors or the fan button. d.
Shunt Trip Follow Fans (Optional) If this option is ON, the shunt trip will be energized whenever the fans are off. This is meant to prevent electric cooking appliances from running when the fans are off and is only required in some jurisdictions. This option can be enabled under Configuration/Misc Options/Shunt trip Follow Fans. Factory Default Setting is OFF. Dimmable HMI (Optional) This option allows the backlight on all HMIs to turn off whenever a timer is satisfied.
