EnForcer™ SCR
Service Manual
I.B. 1561
30
Since you have removed the SCR / Diode Block gate leads from the harness, take special care in reconnecting the SCR /
Diode Blocks firing lead connections making sure that:
1) Phase A is connected to phase A.
2) Phase B to phase B.
3) Phase C to phase C.
PRINTED CIRCUIT BOARD (PCB)
Removal
CAUTION:
Use an anti-static wrist strap (i.e. EnerSys part number 174-2-1) when handling, removing and replacing
circuit board assemblies.
Please follow these steps to remove a PC board. (Be sure your hands are clean before touching a PCB).
1) Turn the AC power OFF.
2) Unplug the battery.
3) Touch your finger to a ground to remove any static charge.
4) Unplug the connectors from the PCB.
5) Remove the 11/32” nuts from PEM studs that hold the PCB to charger door.
NOTE
: Handle the PCB with care. Do NOT place it on top of the battery or other acid-contaminated surfaces.
6) Place the removed PCB into the anti-static bag (or foam) that the replacement board was in.
Replacement
Please follow these steps to install a PCB:
1) Using the 11/32” nuts that held the old PCB to the PEM studs, mount the replacement board on the door.
2) Tighten the 11/32” nuts slowly and gently. Tighten nuts only enough so that the tactile switches are just able to
activate through the front decal.
Over tightening of the 11/32” nuts on the PCB will result in damage to the
tactile pushbuttons.
3) Attach the connectors to the replacement board.
Be careful to insert the connectors properly. The
connectors should be inserted so that the raised portion of the socket slips under the raised portion of
the plug on the PCB.
4) Enter USER/SERVICE parameters. Set all USER/SERVICE parameters such as cell size, amp-hours etc.
accordingly.
5) Turn AC power ON. Connect battery and insure proper charger operation.
VOLTAGE CONVERSION
These chargers are designed to operate from nominal line voltages as marked on the nameplate. The line voltage to
which the charger is to be converted must be one of the voltages shown on the charger nameplate.
DANGER:
POWER MUST BE DISCONNECTED BEFORE CHANGING AC INPUT CONNECTIONS.
AC INPUT CHANGE (STANDARD)
NOTE:
Chargers with optional Quick Tap™ please refer to AC INPUT CHANGE WITH QUICK TAP™.
1) Change AC fuses to the value of the desired line voltage available for this charger. AC fuse values can be found
on the decal inside the charge, or in charts contained in this manual.
2) Change provided jumpers, on the main transformer primary tap location, as shown on the decal inside the door of
the charger, or on the following charts. Jumpers not being used are stored in the manual envelope, inside the
charger.
3) Indicate the line voltage change on the decal inside the charger.
