To install the advance relay on hydraulic press brakes follow these
instructions:
1.
Disconnect power to the press brake.
2.
Examine the electrical schematics of the press brake to
determine the control voltage at the ram up circuits.
3.
Locate the connection points to wire the advance relay in
parallel with the up relay or solenoid on the electrical
schematics.
4.
Locate these connection points in the press brake’s power box.
5.
Install a cord-grip conduit fitting at the bottom of the press
brake’s power box by punching a 1/2" (12.7 mm) hole through
the power box.
6.
Route the two-conductor cable through the fitting into the
power box and up to the connection points.
Hint
Leave extra cable length until verifying the proper operation.
7.
Strip back the required amount of outer insulation. Do not cut
off the shield.
8.
Strip back 1/4" (6 mm) of insulation from the individual wires
and install in the connection points.
9.
Connect the shield to a ground lug or common point within
the press brake’s power box. If necessary, use a butt splice and
16- to 18-gauge stranded wire to add extra length to the shield.
Warning
Avoid locating this cable next to the
high voltage wiring.
10.
Select a relay with a coil voltage that matches the press
brake’s control voltage.
11.
Install the selected relay in the K4 socket on the Relay board
located inside the Large AB6 power cabinet (see the Relay
Board figure at the end of this section).
