Page 32 OFE Series Weight Loss Feeders
6-5-4 Output Signals from Programmable Controller
The OFE Feeder uses several output control signals to control the process. All of these
are very similar in nature, the first of which is the auger motor control.
The auger motor outputs are driven from a control output from the controller.
Each OFE Feeder includes an auxiliary customer alarm output. This dry contact can be
used to switch a remote alarm signal.
The customer alarm output is provided to actuate or energize a variety of alarm horns,
buzzers, strobe lights, and beacons. These are normally provided by the customer, and
care will have to be exercised not to exceed the maximum current draw (3 amp
maximum). The contacts will close whenever the control detects a fault that will
somehow inhibit the blending system from properly blending the material.
Note : The customer alarm contact is open if the panel control power is turned
off.
This contact is for use with a customer supplied alarm device as described
above.
The alarm contact has a maximum load of 3 amps.
