Winco DGC-2020 - Manual (Page 213)

SECTION 7
 MAINTENANCE AND
TROUBLESHOOTING
MAINTENANCE
Preventative maintenance consists of periodic replacement of the backup battery (optional) and
periodically checking that the connections between the DGC-2020 and the system are clean and tight.
DGC-2020 units are manufactured using state-of-the-art, surface-mount technology. As such, Basler
Electric recommends that no repair procedures be attempted by anyone other than Basler Electric
personnel.
Backup Battery for the Real Time Clock
The backup battery for the real time clock is an option available for the DGC-2020 Digital Genset
Controller. A 3.0 Vdc, 195-mAh lithium battery (type Rayovac BR2032) is used to maintain clock function
during loss of power supply voltage. In mobile substation and generator applications, the primary battery
system that supplies the DGC-2020 power supply may be disconnected for extended periods (weeks,
months) between uses. Without battery backup for the real time clock, clock functions will cease if battery
input power is removed.
The backup battery has a life expectancy of approximately 10 years. After this time, you should contact
Basler Electric to order a new battery, Basler Electric P/N 38526.
Battery access is located on the rear side of the DGC-2020.
CAUTION
Replacement of the backup battery for the real-time clock should be performed
only by qualified personnel.
Do not short-circuit the battery, reverse battery polarity, or attempt to recharge
the battery. Observe polarity markings on the battery socket while inserting a
new battery. The battery polarity must be correct in order to provide backup for
the real-time clock.
It is recommended that the battery be removed if the DGC-2020 is to be operated
in a salt-fog environment. Salt fog is known to be conductive and may short-
circuit the battery.
NOTE
Failure to replace the battery with Basler Electric P/N 38526 may void the
warranty.
TROUBLESHOOTING
If you do not get the results that you expect from the DGC-2020, first check the programmable settings for
the appropriate function. Use the following troubleshooting procedures when difficulties are encountered
in the operation of your genset control system.
Communications
Ethernet Port Does Not Operate Properly
Step 1. Verify that the proper port of your computer is being used. For more information, refer to
Section 4, BESTCOMSPlus Software, Communication.
Step 2. Verify the network configuration of the LSM-2020 and DGC-2020 are set up properly. For more
information, refer to Section 4, BESTCOMSPlus Software, Communication.
