Airflow Sensor
An Airflow Sensor is incorporated as one of the inputs to the controller. Remove
the plugs and connect the tubing from the Pitot assembly to the airflow sensor
inputs above the drive hub. (Refer to Illustration 1.)
Connecting Outputs
The Controller provides three output connection options configured according to
the model. Locate your model from the units discussed below:
7001/7051 and 7002/7052
These models provide three universal outputs O1, O2 and O3. They will provide
0/12 VDC at a maximum of 50 mA in Digital mode or 0-10 VDC at a maximum
of 30 mA in Analog mode. Returns are connected to the GND connections on the
left end of the strip. (Refer to Illustration 2 and 3.)
7003/7053
These models are unique as described below: (Refer to Illustration 4.)
Out 1
– This is a universal output that may be used as an output option. Output
ratings are the same as on the other models.
T2
– This Triac output will switch a maximum voltage of 30 VAC. It is rated for a
minimum current of 20 mA and a maximum of 1A. Use the RET terminal for
the triac return.
R3
– This output is assigned as the Normally Open Relay Output. The output
will switch up to 30 VAC/DC at up to 2A maximum. The return connects to the
COM terminal.
RJ-12
An RJ–12 connector is provided for connection to the KMD-1001 NetView or the
KMD-11xx Series NetSensor or a PC. Simply place the appropriate cable con-
nector in the provided RJ–12 connector and connect the other end to the device.
Board Configuration
Configuration settings may be required for the inputs or the RS-485 connection.
If you must activate or deactivate pull-ups on the inputs or set the end-of-line
termination for the RS-485 connection, refer to Illustration 7 to locate the
switches for these settings.
