9E-864C StepMetrix™ Installation Instructions 34
7.3
Fan
1. Note whether or not the status LED is flashing green
located on the front of the controller.
2. Shut off the circuit breaker to the power supply of the
controller.
3. If the status LED was flashing green wait for LED D28
to turn off, then continue to the next step. It could take
several minutes for D28 to turn off. (see Figure 14b
[BM] or 26 [ISO] ). If the status LED was not flashing
green continue to the next step.
4. Connect the discharge resistor to J44 of the power
board (see Figure 14b [BM] or 26 [ISO]).
5. Wait for all LEDs on the power board to turn off. (2-3
minutes).
6. Disconnect the discharge resistor from J44 of the
power board. The system will not restart with this
resistor connected.
7. Disconnect and the remove fan (see Figure 14).
8. Install the new fan.
9. Switch on the circuit breaker to th e StepMetrix
controller power supply.
7.4
Hard Drive
1. Note whether or not the status LED is flashing green
located on the front of the controller.
2. Shut off the circuit breaker to the power supply of the
controller.
3. If the status LED was flashing green wait for LED D28
to turn off, then continue to the next step. It could take
several minutes for D28 to turn off. (see Figure 14b
[BM] or 26 [ISO]). If the status LED was not flashing
green continue to the next step.
4. Connect the discharge resistor to J44 of the power
board. (see Figure 14b [BM] or 26 [ISO] ).
5. Wait for all LEDs on the power board to turn off. (2-3
minutes).
6. Disconnect the discharge resistor from J44 of the
power board. The system will not restart with this
resistor connected.
7. Remove the hard drive from its mou nting bracket and
disconnect the ribbon cable (see Figure 14 or 22).
8. Connect the ri bbon cable to the ne w hard drive an d
install it on the mounting bracket.
9. Switch on the circuit breaker to th e StepMetrix
controller power supplies.
7.5
Load Cell Signal Conditioning Board
1. Note whether or not the status LED, located on the
front of the controller, is flashing green.
2. Shut off the circuit break er to the po wer supply of the
controller.
3. If the status LED was flashing green, wait for LED D28
to turn off, then continue to t he next step. It could tak e
several minutes for D 28 to turn off (see F igure 14b
[BM] or 26 [IS O]). If the status LED was not flashing
green continue to the next step.
4. Connect the discharge resistor to J4 4 of t he power
board (see Figure 14b [BM] or 26 [ISO]).
5. Wait for all LEDs on the po wer board to turn off. (2-3
minutes).
6. Disconnect the discharge resistor from J44 of the
power board. The system will not restart with this
resistor connected.
7. Disconnect the load cell wires; unplug the po wer
connector and the ribbon cable.
8. Replace the load cell signal conditioning board.
9. Connect the load cell wires, power connector and
ribbon cable.
10. Switch on the circuit breaker to the StepMetrix power
supply.
11. After replacing the loa d cell signal conditioning board,
the system must be re-calibrated (see Section 2.5).
7.6
Control Assembly
1. Note whether or not the status LED is flashing green
located on the front of the controller.
2. Shut off the circuit breaker to the power supply of the
controller.
3. If the status LED was flashing green wait for LED D28
to turn off, then continue to the next step. It could take
several minutes for D28 to turn off (see Figure 14b
[BM] or 26 [ISO]). If the status LED was not flashing
green continue to the next step.
4. Connect the discharge resistor to J44 of the power
board (see Figure 14b [BM] or 26 [ISO]).
5. Wait for all LEDs on the power board to turn off. (2-3
minutes).
6. Disconnect the discharge resistor from J44 of the
power board. The system will not restart with this
resistor connected.
