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 11B for correct orientation.
Speed Control Potentiometer
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.
Setup Selection Switches
There are four dipswitches on the control board that are used to configure the
board for specific applications. The switches are numbered 1 through 4, with
1 being the top switch when viewing the control board as shown in the figure.
They are read only at power-up, meaning that any changes to switches will

the switches are as follows:
Switch 1 - Motor Rotation Selector Switch
This switch determines the default or "forward" direction of rotation of the
E24™ motor. When the switch is in the "ON" (right) position the motor rotates
clockwise when viewed from the back of the motor. When the switch is in the
"Off" (left) position the motor rotates counter-clockwise when viewed from
the back of the motor.
Switch 2 - Input Type Selector Switch
This switch is used to set the type of input accepted by the "motor-run" input
terminal and the "motor direction" input terminal. It does NOT affect the
EzLogic® controller connector input. When the switch is in the "Off" (left)
position the inputs are "NPN" type; that is , an input is activated by connecting
the terminal to DC(-) terminal using a jumper wire or through a switch. When
the switch is in the "ON" (right) position the inputs are "PNP" type; that is, an
input is activated by connecting the terminal to the +24VDC terminal using a
jumper wire or through a switch. PNP is recommended.
Switch 3 - Dynamic Braking Enable Switch
This switch is used to enable the dynamic braking feature. When the switch
is in the "Off" (left) position the dynamic braking feature acts to stop motor
rotation quickly when the motor is turned off. When the switch is in the "ON"
(right) position the motor will coast to a stop when it is turned off.
Switch 4 - Current Limit Selector Switch
This switch selects the maximum current that the control board will allow the
E24™ motor to use. When the switch is in the "Off" (left) position the current
limit is set at 1.5 amps. When the switch is in the "ON" (right) position the
current limit is set at 3.0 amps. for most applications the switch should be set
to the "ON" position.

SOLUTION
1) Check AC power.
2) Set disconnect to "on."
3) Replace fuses.
4) Check output power of power supply.
5) Check EzLogic® connections and IOP.
1) Connect wiring harness and pin connector to power pins on
Control Board.
2) Connect cables.
3) Connect motor power connector to motor control board.
4) Clean lens.
5) Replace reflector.
6) Replace EzLogic® zone controller.
7) Replace motor.
8) Replace fuse.
9) Replace control board.
10)Replace motor.
1) Clean lens.
1) Enable sleep feature.
2) Unblock upstream zone.
1) Check input cable and signal source.
1) Loosen butt couplings and pivot plates to square/straighten
frame.
1) Ensure that motor is in high current mode (switch 4 is ON)
2) Replace any rollers that will not freely rotate when belt tension
is removed
