Component

Power failure protector board assembly

Problem

When an electrical power interruption ocurrs, the platesetter turns off and then on again, according to the behavior of the power lines. An electrical power surge can cause machine components to explode or burn.

Solution

Add a power failure protector board to maintain the platesetter in an off status until the On/Off push button is toggled.

Time needed to implement

20 minutes

Parts needed

Procedure

Power Failure Protector Board Installation

1. Shut down the platesetter.
2. Remove the platestter's lower back panel.
3. Disconnect connector J4 from the distribution box.
4. Connect connector J4 (disconnected in step 3) to the male connector on the new Pwr_Fail_PROT_Brd cable.

5. Connect the other side (female connector) of the Pwr_Fail_PROT_Brd cable to connector J4 in the distribution box.

6. Replace the platesetter's lower back panel.

Testing the Power Fail Protector Board Installation

1. Restart the platesetter by releasing either of the two yellow pushbuttons at the rear of the platesetter (the pushbutton remains pushed out); then make sure:

• The platesetter monitor is ON
• The platesetter has started

2. Switch off the main power circuit breaker on the distribution box (without pressing the yellow pushbuttons).
3. After 2-3 seconds, switch on the distribution box's main power circuit breaker; then make sure:

• The monitor is off
• The platesetter is not working

4. Push in the yellow pushbutton (released in step 1); then release it. The platesetter should operate properly now.
