RPS-0146 05/01 Installation Procedures
Instruction Sheet
BMK-3 Installation
The following procedures will convert any model B2000
to the latest electrical circuit control system. Models
manufactured prior to 1993 will require a change to the
molex connectors using the jumper wires enclosed.
A BMK3 assembly consists of the entire new circuit control
mounted in a new rear handle. The Power cord and pendant
control are not included. Those items must be removed from
the bender and installed into the new BMK3 handle. Figure 1.
Figure 1. BMK-3 Assembly
WARNING:The power cord must be unplugged prior to
working on the electrical circuits of the B2000 Bender.
1. Remove the six hex head screws, which mount the handle
to the bender frame.
CAUTION: Once the mounting hardware is removed
hold the handle to prevent it from falling. If the handle falls
out of the frame it will damage the wiring harnesses.
2. Remove the four hex head bolts and two mounting
brackets, which secure the rear handle to the bender
frame.
3. Slide the handle assembly partially out of the bender
frame. Disconnect the wire harness connectors from the
printed circuit board. Units manufactured prior to 1993 will
have two rectangular connectors for the harnesses and
will require jumper wires to convert the harnesses. Units
from 1993 to 2000 will have the current square connectors
and do not require jumper wires.
4. Remove the power cord and pendant cord from the old
handle assembly. Install these items into the BMK3 handle
using the same hardware.
5. Plug the harness connectors into the correct receptacles
on the printed circuit board.
