Faults; Warnings; Shutdowns; Ats Communication Errors - Kohler 14RES Manual

4.8 Faults

Fault codes and conditions are shown in the table on the
following pages, Figure 4-8.
classified as warnings or shutdowns.
4.8.1

Warnings

The controller displays a fault code but the generator set
does not shut down on a warning. The controller resets
automatically after a warning condition is corrected.
4.8.2

Shutdowns

Under a fault shutdown condition, the generator set
shuts down automatically and the controller displays a
fault code. In some cases, the engine cooldown cycle
runs before the engine shuts down.
Shutdown switches (such as the low oil pressure switch
or high engine temperature switch) on the generator set
will automatically reset when the problem is corrected.
However, the fault condition at the controller does not
clear until the controller is reset.
The generator set cannot be restarted until the fault
condition is corrected and the controller is reset. See
Section 4.8.5 to reset the controller after a fault
shutdown.
4.8.3

ATS Communication Errors

An ATS fault can be caused by the following conditions.
When a Model RRT transfer switch is used, an ATS
D
fault indicates that communication with the interface
board on the transfer switch has been lost. The
generator set shuts down. Check the connection to
the ATS interface board.
If an RRT transfer switch is connected after the
D
controller has powered up, the ATS warning is
displayed. To clear the fault, disconnect and then
reconnect battery power to the controller.

4.8.4

Fault Code NoEC

The RDC and DC controllers display the fault code
NoEC (no engine configuration setting) when the
controller parameters have been lost or reset to the
default settings. Do not replace the controller
because of a NoEC fault. Change the Ec parameter to
the setting shown in Figure 4-12 for the generator set
model. Also check the Uu setting and change it, if
necessary. See Section 4.10 and Installation Manual
TP-6733.
The controller parameters may reset to the default
settings if the power to the controller is repeatedly
connected and disconnected (for example, when the
battery is connected or disconnected during installation
or service). To prevent controller reset when connecting
or disconnecting the battery, remove controller fuse F3
before disconnecting or reconnecting the battery
cables. See Section 4.3.1.
A service replacement controller also displays NoEC
and requires this procedure to set the parameters at
installation. See TT-1568, provided with the
replacement controller, for instructions.
Models 14/20RES: Use the RDC controller keypad or
Kohlerr SiteTecht software to set the RDC controller
parameters. Follow the instructions in generator set
Installation Manual TP-6733 or see TP-6701, SiteTech
Software Operation Manual.
Models 14/20RESL: Use Kohlerr SiteTecht software
to set parameters on the DC controller. See TP-6701,
SiteTech Software Operation Manual, for instructions.
