        Frequently Asked Questions

        hide show

        Why is there a voltage present at the terminals of the open contact of an IHP digital time clock.?

        The new generation programmable time switches (CCT15720, CCT15721, CCT15722, CTT15723, CCT15850, CCT15851,CCT15852, CCT15853, CCT16650 and CCT15652) integrate the O-crossing technique. This is an electronic procedure enabling the circuit to be opened at zero current, which enables the electromechanical contact to be operated off-load.

        This is used to avoid the inrush currents of certain loads, particularly lighting.

        This solution involves a low leakage current traveling through the electronics which generates residual voltage at the contact terminals, even when open. This can cause problems when very low loads (small relays, LEDs, etc.) are operated, as the receiver may be "held on" by this spurious voltage. 

        For this type of application (low load), a conventional electromechanical programmable time switch should be used.

        Is the CCT15725 available in 24v dc

         Only available in 240v only

        Why can't I measure a voltage on the time switch output contacts.

        The time switches have a "volts free" contact which means that the contact is not connected internally to the time switch power supply.

        The contact needs to be separately fed (usually linked across from the incoming live)

        What does the plug shaped symbol on the display of a CCT15940 time switch mean?

        The plug symbol means that the timer is in power fail mode.
        This means that the mains supply of the timer is no longer present.
        The symbol will disappear as soon as the mains are reconnected.


        Is there an equivalent part for the ITM4C-6E?

        Yes the CCT15940 4 channel output.

        Instructions for Merlin Gerin timer CCT15837 or CCT15854

        See the attached installation instructions for both timers.


        Is the CCT15837 still available for Purchase?

        No, the CCT15387 has been superceeded by the CCT15838. This only has 1 N/O contact.

        Why the CCT15940 time switch does not operates again, after the electrical power has resumed?

        If the timer has been connected all the time to mains, then it seems that the timer has been damaged (maybe due to high voltage or spikes in the network).

        What is a CCT15284

        It is an IC2000 - twilight switch

        What is the new code for the CCT15837 timer?

        The new code is CCT15838, but the CCT15838 only has a N/O contact not a C/O contact like the previous version.

        What is the replacement for CCT15837 ?

        The replacement is the CCT15838 Which has higher load ratings but is a N/O contact instead of a C/O
