Test procedure for the BCD switch
The BCD switch controls the speed of the gathering belts. It can be checked for proper
operation by following these steps.
1. Open the main electrical enclosure.
2. Turn the disconnect switch “ON”.
3. Push the “ON” button located on the door to
engage power.
4. Locate the BCD LEDs (Light Emitting
Diode) on the Amplifier Board. The 4 BCD
LEDs are labeled (BCD 1, BCD 2, BCD 4,
and BCD 8).
5. Observe the LEDs while changing the setting of the BCD switch, located on the
operator control box. The LEDs should display in binary whatever is set on the
switch. For example if the switch is set at 11 the LEDs labeled BCD 1, BCD 2, and
BCD 8 should be on. All the BCD LEDs should be on at the setting of 15, and they
all should be off at the setting of 0.
6. If switch is not working, you can temporarily place jumpers between the BCD lines
and ground. For instance, to get a speed of 10, place a jumper from BCD8 to
ground and another from BCD2 to ground.
The following test procedures may require that tests are
made with the electrical enclosures open and power
turned “ON”. These tests should only be conducted by
authorized personnel who are aware of the electrical and
mechanical hazards present.
