teleCARE IP
Table 5. Control Circuit Board LED Diagnostics
Note:
1 Relates to the A+/A- terminals on TB4. Not used in teleCARE IP.
2 A battery fail indication can occur if there was an AC failure within the first 24 hours
after initial power-up and the battery voltage had been discharged to a voltage of
20.5Vdc or less. The BAT TRBL LED may also illuminate steady, after a certain delay
during charging, to indicate the battery was discharged and may not support full
load. The delay is based on operational conditions (time remaining in the first 24
hours and time in stand-by) and will automatically reset if the battery charging has
time to reach its full float voltage.
3 SIG4 TRBL through SIG1 TRBL associate with TB4 terminals 4L1/4L2 through 1L1/1L2
respectively.
4 The HPFF8 has Trouble Memory for the supervised outputs. This is useful as an aide in
knowing when past troubles have occurred and if intermittent problems are present
on the SIG4 through SIG1 output circuits.
5 If all four SIG TRBL LEDs are illuminated steady, check if the Reference Resistor is
missing or doesn’t match the EOL resistor used to terminate the teleCARE IP Power
Bus. Otherwise, each power circuit probably has a trouble.
6 To restore a SIG4 – SIG1 blinking LED to normal, press SW2 on the Control Circuit
Board or, power cycle the HPFF8 OFF/ON.
