TFIO module isolation test
This test will need to be performed if the unit is configured to include TFIO modules, the unit's battery pack output voltage is not
remaining consistent and no errors were found during the previous auxiliary equipment isolation test.
Step-by-step instructions
Disconnect the solar panel charger or AC charger.
Disconnect the battery pack cable from the XRC
Disconnect the TFIO module cable from the J18 I/O expansion connector, remote communications equipment and
auxiliary equipment.
Connect the current measurement troubleshooting cable (Part No. 2017350-xxx, see Figure 82) to a known good battery,
and connect to the XRC
Using the DMM, measure the average current. If equal to or greater than 80 mA at 12 Vdc, disconnect the battery pack,
reconnect TFIO module cable with one module connected, and continue to next step.
Using the DMM, measure the average current. Low power TFIO modules generally do not draw over 0.30 mA at 12 Vdc.
If the average current drops less than or equal to 0.30 mA, disconnect the battery pack and connect one additional
module. Repeat this step for additional modules until all have been connected or equipment fault has been located.
If a power drain has not been located, return to the Power troubleshooting flow chart (see Figure 80).
SLEEP mode
The SLEEP mode is a safety feature which maintains the RAM but discontinues data measurement calculations and control

functions. When the XRC
G4
below 11 Vdc, the XRC enters SLEEP mode.
If battery voltage is still below 10.9 Vdc, when disconnected locally, the XRC
G4
above 11 Vdc, the XRC remains awake.
G4
The XRC has a real-time clock which maintains time and date during SLEEP mode and writes an event record when entering
and leaving the SLEEP mode.
G4
Upon wake-up, the XRC performs the following functions:
–
Stores present calculation period accumulations in historical record.
–
Zeros present calculation period accumulations.
–
Ends current daily record and starts a new daily record.
Step-by-step instructions
Connect locally to the XRC
Check the battery pack cable. It must make a good secure electrical connection with XRC
(see Figure 77: Battery charger and battery pack connections).
If the battery pack cable is securely connected, check the battery pack voltage. If voltage is low, replace with another
battery pack.
Reset procedures
G4
The XRC operating system can be reset through either a COLD or WARM start procedure. The decision to use these
procedures should only be made by an experienced technician.
COLD start overview
A COLD start clears all the data that is stored in RAM as well as resetting all entered variables to their factory default values or
to the values last written to the tfCold drive by the Save and Restore utility. A COLD start should be used for new XRC
installations. This will ensure that all memory is clear and the operating program is at its default settings. Discretionary use of
this procedure is advised.
