3.13 Set Maintain
This menu controls the service feature that is used to alert the user of required
generator maintenance and can be enabled or disabled from this menu. If
enabled, the count interval menu allows the user to set the number of hours
until next service. The number of hours to next service is displayed in the Basic
Setup menu under Maintenance (see Table 6 on page 90).
Once the count interval reaches 0 hours it displays a service message, records
the event in the Event History Log, and continues to count down, displaying
negative hours in the Maintenance submenu, until it is reset by a technician. The
reset counter submenu is used by the technician to reset the counter after
service is performed. The service feature does not count down to the next
service until it is reset in this menu.
3.14 Set Modbus
The GSC400 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 E Modbus Map on page 123 for more communication interface
details.
3.15 Common Faults
The Common Fault 1 and Common Fault 2 menus allow the user to select
multiple warnings, failures, and events to generate a trigger when active. The
trigger can be used to turn on a configurable 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. Not all warnings,
failures, and events are supported.
A configurable 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
Output 2 menu to allow the trigger to turn on the configurable output (see section
3.10 Digital Output (Configurable Outputs) Setup on page 69).
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 configurable output to respond to failures only. This
configuration is not available in the front panel menu system; the PC Configurator
must be used. By default all failures, warnings, and events are allowed.
