External MPCE Monitoring: Checking DS5 and DS6
These LEDs help diagnose problems relating to external MPCE monitoring. If you are using
external MPCE monitoring do the following:
1. Block the light curtain and look at LEDs DS5 and DS6 (see Figure 2-14 for location).
They should both light up orange.
2. If only one lights up, or if neither lights up, check the machine control circuit.
3. Verify that MPCE wiring is correct and check that MPCE jumpers J14 and J15 are both
set for “external.” See Chapter 2.
