8.20
Turn off the power to the charger and check the tap settings of the charger transformers (See the Charger owner’s
manual). Following the guidelines in the manual, adjust the taps if necessary.
8.21
If battery electrolyte temperatures are well below 32 degrees F, the charger will not be able to adequately charge the
the battery. Battery insulation or heaters would be required to keep the battery electrolyte temperatures close to
32 degrees F.
8.22
A faulty lift interrupt on a lift truck can cause the battery to be over or under discharged. Check the interrupt voltage
of the interrupt following the procedures found in your truck and/or lift interrupt operators’ manual (s).
8.23
Repeated manual disconnecting of the battery from the charger before complete can cause long term battery damage
and lead to inefficient truck/battery operations. When it is necessary to stop the charge cycle before charge
complete,
always terminate the charge cycle by pressing the STOP key before disconnecting the battery from the
charger.
8.24
If the application requires a larger AH battery than is presently in use, the only long term solution is to replace the
battery with one of the proper AH rating.
8.25
If the control is set to perform forming cycles, DV/DT termination is disabled, and the low current shutdown is
disabled. To return to normal operation, program the control to “00” Forming Cycles (see the “Programming Your
SCR2000 Control” chapter of this manual).
8.26
Program the control to DV/DT charge termination (see the “Programming Your SCR2000 Control” chapter of this
manual).
8.27
If fully discharged batteries are desired for efficient operations, lift interrupts can be installed on the trucks to allow
the operators to recognize a fully discharged battery.
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). A delayed start can be programmed into the SCR2000 control to add a specified delay time between battery
connection and the start on the charge (see the “Programming Your SCR2000 Control” chapter of this manual).
8.29
Battery is being discharged at too high (fast) of a rate. Consult the battery manufacturer or distributor for applications
assistance.
8.30
Check and repair/reconnect connections between the last charger that is polling properly and the next charger
connected (see your CDAC Owners Manual).
8.31
Reboot computer and select “Restart CDAC after abnormal termination” menu item (see your CDAC Owners
Manual).
8.32
Check for control operation on all CDAC connected chargers down stream of the last connected charger that is polling
properly (or all CDAC connected chargers). Loss of AC power connections or proper control transformer voltage will
prevent proper CDAC operation (see CDAC Owners Manual).
8.33
The Charger I.D. function in the SCR2000 Control should be set to 0000 for proper normal (non-CDAC) operation
(see the “Programming Your SCR2000 Control” chapter in this manual).
8.34
Replace damaged and/or incorrect shunt with one of correct size.
8.35
Program the forming cycles feature of the SCR2000 Control to the number of cycles required to properly form the
battery (see the “Programming Your SCR2000 Control” chapter of this manual).
WARNING: Enabling the Finish Cell Forming feature will cause the charger to continue to run for a
period of time if the battery has been disconnected before Charge Complete or pressing the Manual
Stop key. This condition will continue until the programmed number of cycles have been completed.
The battery should never be disconnected while a charge is in progress.
