            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.

            Cause:
            Identifying product compatibility

            Resolution:
            The CAD32BD with DC coil has built-in coil suppression protection as standard so the LA4DC1U is not needed.

            All Products

            Cause:
            Product selection

            Resolution:
            No.  The voltage code BD3 is for the CA4D Low Consumption relays only.   A 24 volt DC coil with built in transient suppression is not available on the CA3D relay.    Use the add on LA4DA1E varister style or the LA4DC1U diode style add on transient suppressors on the CA3D relays.

            No action on logical input, logical input out of order.

            Goals and Symptoms

            No action on logical input, logical input out of order.

            Facts and Changes

            Logical Input
            LI1, LI2, LI3, LI4

            Causes and Fixes

            This phenom can occur when the 24V used for the logical input is connected in some coil of relay or of electromagnet and so on.
            It's due to the overvoltage generated by Ldi/dt when you cut a continue voltage on a coil (L).
            It's possible to reduce the level of this overvoltage, use LA4KC1B or LA4DE2U.

            Will a LAD4RCE or LA4DRCU also fit a LC2D09 thru LC2D38 reversing contactors?

            Environment:
            Products sold and used in the United States

            Cause:
            Accessories used on non-reversing contactors are also needed for reversing application

            Resolution:
            Yes, the LC2D contactors are provided standard with one on the left contactor. One may be added to the right contactor.

            Resolution:
            LC1D80 and LC1D95 does not have an internal bi-directional peak limiting diode on their DC coils. LA4DC3U (Screw connection of wire to the contactor coil terminals 24–250 Vdc, 3p-4p) must be ordered separately.

            The LC1D09 to LC1D38 have an internal diode by default on their DC coils.
