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. Through a digital Building Management System. Refer to the Building Management
Owner’s Manual for more information.
5. If the surfactant level is too low, an alarm will be triggered on the HMI. If the wash cycle is
initiated while this alarm is active, water will be sprayed but no surfactant will be injected. Refill
Surfactant as soon as possible for best results. (Refer to Self-Cleaning or CORE Manual for
additional information)
Fan Proving Interlock (Optional) (i.e. Loss of Load Interlock/Airflow Fault Interlock)
1. This function is designed to prevent exhaust fans from running if the supply fans are not running,
which in turn would shut off the cooking equipment. In practical terms, this means that all fans will
shut off along with cooking equipment if any of the exhaust or supply fans are not properly
running. Examples of reasons why a fan would not be properly running are: overload tripped,
broken fan belt, defective motor, disconnect switch off, etc.
2. This function requires calibration, which can be performed through the Calibration setting on the
ECPM03 LCD.
3. If this option is enabled, the load on all the exhaust and supply fans is constantly monitored. If the
load for an exhaust fan or the load for a supply fan drops below the threshold calculated after
calibration for more than the 35 sec, all exhaust and supply fans will shut down.
4. If an electric gas valve and shunt trip are attached to the system, they will shut down as well.
5. To reset the system after a Proving fault, press the Fault Reset button on the HMI.
CORE Protection Fire System (Optional)
1. If a CORE Protection Fire system is connected to the control panel, alarms from the CORE
system will automatically be displayed on the HMI.
2. Multiple CORE systems can be connected to the same control panel. Refer to the CORE Manual
for setup of CORE Interlock Network addressing to prevent communication conflicts.
PCU Advanced Filter Monitoring (AFM) (Optional)
1. If a PCU AFM is connected to the control panel through Modbus, alarms from the PCU will
automatically be displayed on the HMI.
2. To connect the AFM system to the HMI, run a CAT-5 connection from terminal J3 to the RJ45
port on the PCU AFM internal to the PCU. This is outlined in the installation schematics.
3. Up to 8 PCU AFM can be connected to the same Control panel. . Note that each additional PCU
AFM must be assigned a unique Modbus address. Refer to the PCU AFM manual for more
information. Note that each additional PCU AFM must be assigned a unique Modbus address.
Refer to the PCU AFM manual for more information.
Electric Gas Valve Follow Fans (optional)
This option is only available when an electric gas valve is enabled. If this option is ON, the gas valve is
shut off whenever the fans are off and requires a reset when the fans are turned ON. This is meant to
prevent gas cooking appliances to run when the fans are off and is only required in some jurisdictions.
This option can be enabled under Configuration/Misc Options/Gas Follow Fans. Factory Default Setting is
OFF. NOTE: Appliance pilots must be relit after each fan cycle when this option is enabled.
