                        What is the replacement for a LA6DK10B

                         Part code is LAD6K10B

                        Why does my other equiptment trip when my contactor releases?

                        The colapsing coil voltage on DC is causing a Back EMF (electro magnetic field) issue. This is solved with either a varistor LA4SKE1E or a Diode LA4SKC1U on the LP1K09 contactor.

                        How can I cable to the process PNP and NPN type detectors?

                        PNP and NPN type outputs are available as 3-wire sensors with a DC voltage power supply (the voltage limits are dependent on the specific sensor):
                         
                        PNP type: switching on the positive voltage load
                        NPN type: switching on the negative voltage load
                        These outputs are typical of photoelectric detectors, inductive proximity or other sensors.
                         
                        PNP output
                        The load (relay coil, contactor relay input, PLC input) must be connected between the - and the midpoint.
                        The corresponding PLC input is Sink.

                        Work-around for Missed Alarms Notification Bug in Lotus Notes

                        Goals and Symptoms

                        In Lotus Notes alarms on recurring calendar entries may not clearing. The alarm may have been acknowledged, but the next time Lotus Notes starts up the "you missed alarms" popup appears. Clicking "Done" on the alarms will close the popup, but it will reappear next time Lotus Notes starts. To one's bewilderment, the "missed" alarms can accumulate in the list this way.

                        Causes and Fixes

                        This is a bug known by IBM. A work-around is to switch the welcome screen or home page to the default "Basics" view. Then, restart the application twice.

                          There is also an APAR LO14110 that has a less invasive fix:


                          One observation from this customer: the clients experiencing the
                          problem are all users that have a Welcome Page option that
                          accesses the user's mail file, e.g. Basics Plus Calendar,
                          Workplace, etc... They workaround the problem temporarily by
                          switching to the Basics welcome page, and restarting the client
                          twice. The 1st restart shows the alarms again, but the
                          following restart does not and the CalendarSettings profile doc
                          has a correct LastAlarmDate datetime ( gAlarmLastSentTime in
                          debug output ).
