Installation Instructions
HAWKEYE 708
Solid Core Adjustable Current
Status Sensor
!CAUTION!
•
This product is not intended for life or safety
applications.
•
Installing sensors in an energized motor control center
or on
any energized conductor can be hazardous.
Severe injury or death can result from electrical shock during contact
with high voltage conductors or related equipment. Disconnect and
lock-out all power sources prior to installation.
Applications shown are suggested means of installing sensors, but it is
the responsibility of the installer to ensure that the installation is in
compliance with all national and local codes. Installation should be
attempted only by individuals familiar with codes, standards, and
proper safety procedures for high-voltage installations.
1.
Ensure power conductor to be monitored is disconnected and
locked out from the power source!
2. Install the adjustable mounting bracket to the back of the motor
control center. The sensor may be located at any point on the conductor
between the motor and the motor starter.
3. Align to permit the conductor to fit through the hole. Slide the
conductor through the center hole in the sensor and connect the
conductor to the lugs on the motor starter.
Note:
Low (<1 amp) and high (>135 amps) applications may require
special installation:
a. Low amperage (<1 amp FLA) - to provide adequate current,
wrap conductor through the center hole and around the sensor body to
produce multiple turns and increase flow. Measured current = Actual
Current x Number of turns.
b. High amperage (>135 amp FLA) - current flows in excess of
135 amps require the use of an appropriately sized external current
transformer. Install the external CT on the conductor and run the CT
secondary wire through the sensor.
CAUTION:
CTs can contain
hazardous voltages. Install CTs in accordance to manufacturers’
specifications and instructions.
4. Wire as shown below. Note: Testing the solid-state output of this
sensor with a digital ohm meter may yield inaccurate, but relative
readings of switching (i.e., 6 Meg Ohms.) Use an Analog VOM for
readings similar to loop.
Status output is not polarity sensitive
Orient the current switch so the status output terminal is facing you
and follow method number 1 or 2 below.
1. For under current status indication: (Belt loss, fan & pump
status)
•
Turn the set point screw clockwise until the status closed
LED goes out and the status open LED comes on.
•
Turn the set point screw counter-clockwise until the status
open LED goes out and the status closed LED comes on.
•
Turn the set point screw ¼ turn counter-clockwise.
•
The sensor is now calibrated to provide indication of current
flows below normal full load amps.
Output Status:
Normal: Output closed
Alarm: Output open
2. For over current status indication: (Locked rotor)
•
Turn the set point screw counter-clockwise until the status
open LED goes out and the status closed LED comes on.
•
Turn the set point screw clockwise until the status closed
LED goes out and the status open LED comes on.
•
Turn the set point screw clockwise ¼ turn
•
The sensor is now calibrated to provide indication of current
flows above normal full load amps
Output Status:
Normal: Output open
Alarm: Output closed
!CAUTION!
Status indicators of this device should not be relied on to
determine whether or not the monitored conductor is connected to
a power source. Doing so may result in injury or death from
electrical shock.
