3.3. Basic 

Troubleshooting Procedures. 

Only qualified personnel may perform troubleshooting on the TCR-HHR-02 using Table 3-3. 

Table 3-3.  TCR-HHR-02 Basic Troubleshooting Procedures. 

Symptom

Resolution

Flashing red  EXT DC LED indicator 
when powered via external 115/230 VAC 

Ensure that 115 or 230 VAC power is available at the AC 
cord plug.  There is no AC power switch and no external AC 
fuse (AC fuse is integrated into the AC power supply. 

Flashing red EXT DC LED indicator 
when powered via 12-32 VDC 

Ensure that 12-32 VDC power is available at the DC cord 
plug.  There is no external DC power switch and no external 
DC fuse (reverse polarity and overcurrent/overvoltage 
protection is provided by the DC power control module). 

Flashing Red CELL LED indicator 

Verify the state of charge of all batteries. Recharge as 
necessary and replace into the unit. 

Red CHRG/FLT LED  

Ensure the battery charger module is properly secured to the 
battery.  The CHRG/FLT LED may come on red if the 
battery under charge is fully dead.  The charger module will 
trickle charge the battery and the CHRG/FLT LED should 
change to yellow after 10-20 minutes. If the CHRG/FLT 
LED does not change to yellow replace the battery. 

CHRG ON LED OFF  

Ensure the battery charger module is properly secured to the 
battery.  Ensure the external DC power is > 22 VDC.
