Product Information
The Hawkeye Relay Combination Series is designed to maximize reliability and
minimize installed cost for automation installers.
These units combine a current switch and relay into a single package, offering
status and control in one convenient solution.
The devices allow for start/stop control and status monitoring with a single
device, simplifying installation and reducing space requirements.
Key Features:
- Combined relay & status sensor
- Two outputs for increased control
- Fan & pump status monitoring
- Added flexibility with multiple installation configurations
- Polarity insensitive for easy setup
- Relay and status LEDs for quick visual indication
Applications:
- Detects belt loss/coupling shear
- Fan/pump status monitoring
- Electrical failure detection
Product Usage Instructions
Installation:
- Ensure power is disconnected before installation.
- Mount the unit securely using the provided brackets in the desired configuration.
- Connect the appropriate wires to the terminal block following the specified wire size and torque requirements.
Setting Trip Point:
- Determine the desired trip point for current monitoring based on your application requirements.
- Adjust the trip point using the provided settings on the device.
- Test the functionality by simulating different current levels.
Status Monitoring:
- Observe the relay and status LEDs for indication of device operation.
- Monitor fan and pump status regularly to detect any issues such as belt loss or motor failure.
Frequently Asked Questions (FAQ)
Q: What are the typical coil performance specifications for the product?
A: The typical coil performance includes voltage ratings for AC and DC
operation, pull-in voltage, and drop-out voltage for different models within
the series.
Q: How can I detect belt loss or coupling shear using the product?
A: The product is designed to detect belt loss or coupling shear by
monitoring changes in current draw, allowing you to easily identify issues
such as slipping belts or sheared couplings.

Status and Control in One Package
The Hawkeye Relay Combination Series is the ideal solution for the automation installer. These units combine a current switch and relay into a single package, reducing the space required for total control of fans and pumps. The current switch and relay operate independently of one another. These devices allow start/stop control and status monitoring with one device instead of two.
