Required Controller Settings
To get the car running on construction mode, verify/set the following parameters. Please refer
to “Screen Descriptions” on page 2-5.

• CONFIG02 > System Control Parameters
•Hoist Motor Speed (RPM)
• Inspection Speed (FPM)

Brake Pick and Hold Voltages (SCE-BRK board R3 and up)
Pick and hold voltages are set using the PICK, HOLD and RELEVEL potentiometers on the
SCE-BRK board.
1. Set all three potentiometers on the SCE-BRK board to their fully CCWpoints.
2. Place SCE-BRK jumper JP1 in the PICK_ONLY position. This will allow time to make
adjustment before the controller switches to HOLD mode (normally about 1.5 seconds
after PICK begins with jumper in PCK & HLD position).
3. Place a voltmeter across the brake leads where they connect to the screw terminals
labeled BR+ and BR- on the SCE-BRK board.
4. Use Inspection controls to pick the brake. Adjust PICK voltage using the PICK trim pot.
Do this quickly to avoid overheating the brake coil.
5. Release the inspection controls and allow the brake to drop.
6. Place jumper JP1 in the PCK & HLD position.
7. Pick the brake as before. The controller will first apply pick voltage, then shift to hold
mode. (LED indicators show which mode you are in.) Adjust the HOLD voltage using
the HOLD trim pot.
8. 8.The Relevel Pot may be left fully CCW if the Relevel function is not used on this sys-
tem. In this case place a shunt on the RLVL_DIS side of JP3.
9. If the Relevel function is to be used then begin by placing a shunt on the RLVL_DIS side
of JP3. This disables external control of the Relevel function. To select the manual setup
mode, place a shunt on the RLVL_ADJ side of JP2. This causes the RELEVEL pot to be
selected. In practice this should be set a little lower than the PICK pot and higher than
the HOLD pot. The exact setting can only be arrived at with a running car.
10. Move the shunt on JP2 from RLVL_ADJ to PARK.
11. Move the shunt on JP3 from RLVL_DIS to RLVL_ENA to enable normal Relevel opera-
tion mode via the controller.
If brake voltage is too high or too low and cannot be adjusted to the correct value, you can alter
the applied AC voltage at SCE-BRK terminals BRL1 and BRL2 by changing the connections to
secondary taps (X9 through X16) of transformer T1.
