LED STATUS LIGHTS
Eleven LEDs separated into two banks (see “Fig.
1”) are provided on the faceplate. The LEDs Bank
1 includes 6 LEDs and Bank 2 includes 5. In
Setup mode, these banks form a binary code to
indicate either the controller setup configuration or
error status, which is indicated by the last 8 (red)
LEDs. Refer to Tables 1, 2, 3 and 4 ( See "Cas-
cade Controller Installation and Operations
Manual" supplied with unit) for configuration and
status listings.
One LED is located next to the “AUTO” button to
indicate that the controller is waiting for the remote
start input to become active. The LED status lights
are (from top to bottom) see “Fig. 1”:
Engine running - If the green LED is on, then the
unit is receiving a speed signal, indicating that the
engine is above the crank cut speed.
ECU status - If the green LED is on solid, it
indicates that in a J1939 application the ECU and
the unit are communicating properly. If the LED is
blinking slowly the ECU is broadcasting a mes-
sage. If the LED is blinking fast, the ECU is NOT
communicating properly.
Remote Start/ Crank Rest - If the green LED is
on, then the remote start input is active and if the
system is in "AUTO" mode, it will try to start. If the
LED is blinking, the crank cycle has ended and is
now in crank rest cycle.
Low oil pressure - If the red LED is on, the
controller has caused the engine to shutdown and
lockout. If the LED is blinking, the engine ECU has
transmitted a SPN for an oil pressure related
condition.
High Engine Temperature - If the red LED is on,
the controller has caused the engine to shutdown
and lockout. If the LED is blinking, the engine ECU
has transmitted a SPN for an engine temperature
related condition.
Overspeed - If the red LED is on, the controller
has caused the engine to shutdown and lock out
due to engine speed exceeding the setpoint.
Underspeed - If the red LED is on, the controller
has caused the engine to shutdown and lock out
due to engine speed falling below the minimum
needed for proper operation.
Overcrank - If the red LED is on, the controller
has exceeded the set number of start attempts
The potentiometer is set at the factory. However, if
the voltage reading on the voltmeter is not as
desired use the following procedure to make the
necessary adjustments. With the unit running,
under no load, observe the AC voltmeter. Locate
the voltage adjustment knob on the control panel.
The decal above the knob indicates the direction
to turn the knob to increase or decrease the
voltage. Turning the knob to the right increases
the voltage while turning the knob to the left
decreases the voltage. Slowly turn the adjustment
knob in the desired direction, while observing the
AC voltage meter, stop when the desired voltage
is obtained. The unit is now ready to load. If the
desired voltage cannot be reached contact the
TEREX Service Department at 1-800-433-3026.
