The WaveNet acts as a slave on a Modbus RS-485 network and can – on request by the master
device – remotely transmit warning, failure, and event indications. The device address and baud
rate can be set from this menu.
See Appendix B: Modbus Map for more communication interface details.
Common Fault 1
and
Common Fault 2
menus contain tables of all the events, warnings, and
failures available in the WaveNet controller and allows the user to select those to generate a trigger
when active. The trigger can be used to turn on a digital output, store the status of the trigger (active
/ inactive) to the Modbus Common Fault registers, or both. Both the common fault 1 and common
fault 2 menus generate their own independent trigger and use separate modbus registers and digital
outputs.
A digital output must be set to
Common Fault Output 1
if using the Common Fault 1 menu or
Common Fault Output 2
if using the Common Fault 2 menu to allow the trigger to turn on the digi-
tal output (see section 5.5 Digital Output Setup).
Using the PC Interface, the user can also mask the event, warning, and failure tables for each of the
common faults. For example the user can set the Common Fault 1 modbus register to respond to
events, warnings, and failures and set the Common Fault 1 digital output to respond to failures only.
This con fi guration is not available in the front panel menu system; the PC Interface must be used.
The dummy load feature allows the user to turn on an output if the AC current is below a settable
threshold (
Load On Point
). This is useful for applications where the generator must have a minimal
load to prevent damage to the generator.
Upon crank success (RUN Mode entered), if enabled, the feature waits for a con fi gurable bypass
time, then starts to monitor the AC current. If the AC current remains below the Load On Point for
6.5 seconds then the dummy load digital output is turned on. If the AC current rises and remains
above a settable threshold (
Load Off Point
) for 1.5s, the dummy load digital output is turned off.
A digital output must be set to dummy load to use this feature.
