• HLC/Power Supply Unit for Motor
The E24™ family of conveyors is equipped with a 24 volt DC power supply unit
for providing power to the drive card and motor combination . Each power supply
provided is a high efficiency DC power supply in a sealed industrial enclosure .
The various wiring connections, adjustments and settings, and electrical specifica-
tions of the power supply unit are described in Figure 7A .
Electrical Connections
Input power connections are made inside the enclosure at factory . Wiring harness
power connections are made to connector on the outside of the enclosure .
AC Input
AC power for the HLC power supply unit is connected directly
to the disconnect switch, and the ground wire is connected to
the grounding terminal block . "MC" models are wired to plug
directly into a wall outlet (115 VAC) for easy install without permit
requirements .
The dual voltage single phase input powered units will
automatically adjust to the 115 VAC or the 460 VAC input power .
DC Output
Connect the wiring harness to a connector on the side of the
enclosure .
NOTE: Can NOT have more than 19 cards and motors per
side, or 38 cards total.
• The Motor Control Board
The motor control board is an integral part of the E24™ system . The control
board performs the following functions:
1 . Provides power to the motor .
2 . Allows the motor to be operated by an EZLogic® zone controller or other
control device .
3 . Limits the current to the motor to protect the motor from damage in the case
of an overload or stall condition .
4 . Provides optional dynamic braking .
5 . Allows the default direction of rotation to be selected .
6 . Provides speed control for the motor .
7 . Provides LED's to indicate when the board is receiving power and when
certain fault conditions occur .
The parts of the motor control board are shown in Figure 8A . Each of these
parts and their function are described below .

+24VDC Input, DC (-) Terminals
These terminals provide power to the control board and motor . The two pin
connector from the wiring harness supplies power to this location .
Motor Direction Terminal
This terminal is used to provide a "reverse" signal to the motor control board .
The type of signal used is PNP type and is determined by the position of the
input type selector switch (switch 2) . The actual definition of "forward" and

(CABLE
Mount the power supply unit near the center of the conveyors and connect the
wiring harnesses to each side of the power supply .
A gender changer cable is supplied for one side of the power supply .
Main Power Disconnect Switch
The main power disconnect on/off switch handle is located on the front door. The
switch can be used to turn the conveyor on and off to perform maintenance. It may
be "locked out" in the off position if desired/required.

"reverse" is determined by the position of the motor rotation selector switch
(switch 1) . This input is not used on standard configurations of the E24™
family of conveyors, but may be used in special applications .
Power Indicator LED (Green)
This LED will be illuminated at all times if input power is connected to the
controller with the proper polarity .
Current Limiting Indicator LED (Amber)
This LED will be illuminated if the board is in current limiting mode . This
occurs when the motor load current requirement exceeds the selected
maximum current value . When the current requirement drops below this
value, the indicator will turn off . Fault Indicator LED (Red)
This LED indicates information about various faults, either by flashing or by
remaining in a steady "ON" state . Flash patterns are repeated at four-second
intervals . The indicated faults are as follows:
•
One flash - Board hardware problem
•
Two flashes - Over-Voltage
•
Three flashes - Under-Voltage
•
Four flashes - Internal motor fault
•
Five flashes - Control Board over temperature shut down
•
Six flashes - Extreme over current shut down
•
On steady - Stalled motor
Blown Fuse Indicator LED (Red)
This LED will be illuminated if the replacement fuse is blown .
Motor Connector
This connector accepts the connector on the E24™ motor's cable . The
connection provides power to the motor and allows the control board to

monitor the motor's load status . Note: See Figure 8A for correct orientation .
Speed Control Potentiometer (Mounted to Face of HLC/Power Supply)
The speed control potentiometer is used to vary the speed of an individual
E24™ motor . Speed-up and slow-down areas may be created to gap product,
provide more accurate positioning, etc .
