    193111-047 TROUBLESHOOTING Action 8.01 Refer to the INSTALLATION chapter in the charger manual. 8.02 Disconnect AC power and replace the bad AC fuse. Reapply AC power to the charger. If the fuse (s) blows instantly, check the connections on the input side of the contactor to make sure there are no shorts between any of the input wires .
  • Page 30 Any connections that appear loose or overheated must be re-lugged and rechecked. 8.16 To check expansion board for proper operation, first make sure there is a good connection to the main SCR2000 board. Remove the control and inspect, the connector is located in the lower right of the PC boards. Check for the proper I.D.
  • Page 31 8.28 A cool down can be programmed into the SCR2000 control to add a specified cool down time between charge termination and the signaling of charge complete (see the “Programming Your SCR2000 Control” chapter of this manual).
  • Page 32 8.37 The gassing or 80% charged point may be set too low or high. Try re-adjusting, in small increments. (See the “Programming Your SCR2000 Control” chapter in this manual.) 8.38 If the charger is 3 phase, it is possible that only 1 fuse may be blown. This would cause the charger and control to look as if they function as normal, but at a reduced charging rate.
