          Frequently Asked Questions

          hide show

          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.

          For further information please visit https://www.clipsal.com/Trade
           

          What is the LA4DE1U alternative?

          LA4DE1U TeSys D - suppressor module - varistor - 110...250 V AC/DC

          to suit D40-D115 (3P) and D65-115 (4P):
          LA4DE2U TeSys D - suppressor module - varistor - 110...250 V AC
          OR
          LA4DE3U TeSys D - suppressor module - varistor - 110...250 V DC
           

          Why will LA1SK11 adder deck not fit on CA2SK11 relay?

          Issue:
          Why will LA1SK11 adder deck not fit on CA2SK11 relay?

          Product Line:
          Tesys Relays

          Environment:
          All Products

          Cause:
          Product Features

          Resolution:
          No, LA1SK11 mounts only on the CA2SK20 relay.




          CTA-ID : 2014524

          What is the part number for a diode for a CA3KN relay?

          Issue:
          What is  the part number for a diode for a CA3KN relay?

          Product Line:
          Tesys Relays

          Environment:
          All Products

          Cause:
          Product selection

          Resolution:
          LA4KC1B or LA4KC1E is the diode and zener diode for the CA3KN relay.


          CTA-ID : 2015604

          Will the LA4DC1U work with the new CAD32BD relay?

          Issue:
          Will the LA4DC1U work on the CAd32BD relay

          Product Line:
          IEC relays and accessories

          Environment:
          Products sold and used in the United States

          Cause:
          Identifying product compatibility

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


          CTA-ID : 2031917

          Will the LA4DC1U diode suppressor mount to current Tesys D DC coils?

          Issue:
          Will the LA4DC1U diode suppressor mount to current Tesys D DC coils?
          Product Line:
          IEC contactors and starters

          Environment:
          Products sold and used in the United States

          Resolution:
          No. The LA4DC1U diode unit will only fit the older TeSys D contactors. Tesys D DC coils include suppression automatically, it`s not needed.

          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

          ATV31
          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.

          Is the voltage code BD3 valid for a CA3DN40 relay?

          Issue:
          Is the voltage code BD3 valid for a CA3DN40 relay?

          Product Line:
          Tesys Relays

          Environment:
          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.
