5.3.10. RED BRAKING LIGHT STAYS ON ALL THE TIME
 Make sure the Bus Discharge input is not activated. This causes the
braking module to go full on. Extended operation with this input can
cause load bank overheating and improper operation.
 System voltage is too high or high harmonic content is present. Check
main system rectifier input AC voltage. Refer to the DC Bus Trigger Level
found in Table 2-3. The undistorted main system rectifier AC input
voltage should always be less than
 Note: If the measured DC bus (in standby) is greater than the
1.414 * RMS Voltage Line
then harmonic distortion may exist. Consult the project engineer for the
appropriate corrective action.
 Setpoint too low. The DC Bus Setpoint pot on the main control board
may have been tampered with. If this is a possibility, then the module
needs to be sent in for recalibration.
 Wrong braking module installed. Check the module chassis sticker for
the part number. Refer to Section 2.2 of this manual and verify the sticker
information represents the correct part number for your application and
voltage levels. Remove and replace as required.
 Main control board has gone bad and the module needs to be sent in for
repair.
5.3.11. MASTER UNIT APPEARS TO FUNCTION PROPERLY, BUT SLAVE
UNITS DO NOT SEEM TO FOLLOW THE MASTER
Slave(s) may have missing or insufficient control voltage. Refer to Section
5.3.1 and correct as required.
Check the signal wiring between modules. The terminals should be daisy
chained as described in Section 4.2.3.1.
Make sure that only one module is selected as Master on a network. More
than one master can cause improper triggering and system damage.
5.3.12. ETHERNET/IP LINK SENSED LIGHT DOES NOT TURN ON
Check the cable running between the module and network hub. Check the
network hub port for functionality. Try another port or another cable.
5.3.13. ETHERNET/IP MODULE STATUS LED IS SOLID RED, FLASHING
RED, OR FLASHING GREEN
Make sure your EtherNet/IP scanner is active and connected to the network,
and is programmed with the appropriate EDS file and configuration for this
module.
5.3.14. ETHERNET/IP NETWORK STATUS LED IS SOLID RED
The module has detected a duplicate IP address on the network. Make sure
the address configuration switches are all in the "OFF" position, and assign
the module a new IP address using the IPconfig software.
