53.
Check the SCR as described below. If it tests faulty, replace with an SCR of the proper type.
Connect a VOM set on the 1k Ohms scale; positive to SCR anode (stud), negative to SCR cathode (heavy
red lead). The VOM should read a very high impedance (near open circuit). Touch and hold the SCR gate
lead (small white lead) to the SCR anode. The VOM should read a low impedance (near short circuit).
If the SCR reads shorted before the gate is touched to the anode, the SCR is bad. If the SCR reads open
when the gate is touched to the anode, the SCR is bad (A DVM may be used if it is set to the Diode scale).
A high impedance will be indicated by an over range indication (usually OL), a low impedance will be
indicated by a low reading 1.00.
54.
Disconnect the charger from the battery and the input AC. Blow out the charger with compressed air, and allow the
unit to set unused for 1 to 2 weeks in a warm dry environment (as hot, up to 104° F) and dry as possible.
55.
Replace damaged and/or incorrect shunt with one of correct size.
56.
Reconnect transformer primary wiring to match the schematic included in this manual.
57.
Reconnect transformer secondary wiring to match the schematic included in this manual.
58.
Using a VOM or DVM, check the diode for proper operation as stated below.
Set the VOM to the 1k Ohms scale. Connect the positive VOM lead to the anode (cable lead) and the
negative VOM lead to the cathode (stud). The VOM should read a low impedance (near short circuit).
Reverse the VOM leads. The VOM should read high impedance (near open circuit). Replace any diodes
that fail with the proper part.
59.
Reconnect the input primary jumpers to match the input voltage, see the installation chapter of this manual.
Be sure to connect the control transformer primary properly
.
60.
Program the forming cycles feature of the UC2000 Control to the number of cycles required to properly form the
battery. See the Programming Your UC2000 chapter of this manual.
61.
Reprogram the fixed AH setting of the UC2000 Control to match the battery nameplate AH rating. See the
Programming Your UC2000 chapter of this manual.
62.
Program the UC2000 Control to Multi-cell mode “ON” or program the Fixed cell setting to the proper cell size for your
battery. See the Programming Your UC2000 chapter of this manual.
63.
Set the control PCB shunt size dip switch to match the shunt on the charger (1 leaf = 100A, 2 leaves = 200A,
4 leaves = 400A). Reset by pressing both Arrow keys simultaneously until the display
resets.
64.
Set the Control PCB cell size dip switches to match the charger nameplate cell size. Reset by
pressing both Arrow keys simultaneously until the display resets.
65.
Replace the ampere hour jumper with one that matches the nameplate AH rating of the charger. See the parts list
included in this manual. Reset by pressing both Arrow keys simultaneously until the display resets.
