Component Description
Temperature Sensor
The temperature sensor is a 10K Ohm Thermistor. The
sensor gives constant feedback to the controller. One
sensor is installed in every riser.
Room Temperature Sensor
The Room temperature sensor is a 10K Ohm Thermistor. The sensor provides constant
room temperature to the controller. It should be installed on a wall somewhere in the
space but not directly under the hood or close to an appliance so that the reading is not
affected by heat.
Typically a system will have one room temperature sensor. However systems
configured with 2 fan zones have the option to be ordered with 2 room temperature
sensors, one for each zone. They should be mounted in the space accordingly.
HMI
The HMI is designed to withhold grease and water when installed on
the face of the hood or utility cabinet.
The HMI is connected to the ECPM03 through a CAT-5 cable. If the
HMI is installed on the face of the hood, a high temperature CAT-5
Cable is used.
The HMI can be mounted to a standard 2-gang junction box.
Current Sensor
One or several current sensors are included in the panel when the
Proving Option has been ordered. A current sensor has a solid core and
provides a 4-20 mA analog output that is proportional to the current
measured. It has an adjustable range of 0-10 amp, 0-20 amp or 0-50
amp based on the position of the jumper on the top of it: L, M or H
respectively. The jumper is typically adjusted at the factory. The range
selected should be the smallest range possible that includes the FLA of
the motor being monitored.
