Generator Connections
Site Accessible
Follow these steps to remotely troubleshoot
serial port down
,
communication failures
, or missing data
(follow ATC or other vendor procedures for specific generator alarms):
1.
Launch an ssh session to the site device and enter the command
show controllers
serial
X
to verify that the serial port is enabled and correctly configured
a.
Serial port assignments on the RMM-1400 are:
Generac H100 & H100 HTS – RS232/Modbus (RMM-1400 & RMC-700 port 1)
b.
If not enabled enter the command
config controllers serial X enable
2.
To verify communication on a serial port enter the command
diag line-monitor
serial-
X
.
a.
Type the letter
m
(will not display), then hit the Enter key to start the diagnostic session
b.
Normal, showing data is being transmitted
[seria-1]T>
and received
[seria-1]R<
c.
If data is only being transmitted the controller is not responding due to a disconnected
or bad cable or a controller or software issue any of which will require a site visit
d.
Use
Ctrl-c
to stop the diagnostic process
e.
If a site visit is required
i.
Create a ticket per the
ii.
Create an
to dispatch an ATC FOT to the site to investigate further
3.
If communication is good, verify that measurement values are being reported enter the
command
show meas-table entries
4.
For details (state, originator, NE Name, and values) of a specific measurement by entering the
command
show meas-table entries
measurement_name
5.
If the measurement is offline do the following:
a.
For measurements that are configured by the module (will show as dynamic or
originated by a script):
i.
Enter the command
show site network-elements
NE_Name
to
confirm that the network element is online and configured correctly
NOTE:
Verify the NE type is correct for the system being monitored, if not the site
network element will need to be reconfigured for the correct system
ii.
If the NE state is offline check to make sure that none of the parameters is
displaying a question mark (?) in the value field, if so a correct value needs to be
entered using the command
config site network-element
cabinetDoor param
Parameter_Name Value
(look at a known good
site to find the correct values)
b.
For measurements that are manually configured (will show as static and not
originated by a script):
c.
Confirm the originator is enabled using the command
show discrete
analogs, i
f not enter the command
config discrete analog
X/X
enable
6.
