Note:For details of the recommended substitute products or models with substitute functions, refer to the following information.
2.The substitute product in column (1) is H3CR-A8E Solid-state Timers because digital Timers have higher integrated performance than motor Timers when there are no moving pointers.
It is recommended that the socket is changed to P2CF-08 Sockets for a surface mounting timer. If you continue to use 8PFA Sockets, it must be used with Y92F-42 Adaptors, and PL08 Sockets with Y92H-7 Hold-down Clips.
When using a flush mounting model, Y92F-73 Flush Mounting Adaptors are required because H3CR is smaller than STP.
For Timers with SPST-NO instantaneous contacts, the power supply terminal 2 and instantaneous contact terminal 1 must be externally shorted for H3CR-A8E because they are internally shorted in STP.
Otherwise, no additional wiring or wiring changes are required.
3.The substitute product in column (2) is H2C-8 Motor Timers with moving pointer because only Motor Timers can replicate the moving pointer function.
It is recommended that the sockets are changed to P2CF-08 for surface mounting Timers. If you continue to use 8PFA Sockets, they must be used with Y92F-42 Adaptors, and PL08 Sockets with Y92H-1 Hold-down Clips.
When using a flush mounting model, Y92F-70 Flush Mounting Adaptors are required because H2C is smaller than STP.
For Timers with SPST-NO’ instantaneous contacts, the power supply terminal 2 and instantaneous contact terminal 1 must be externally shorted for H2C-8 because they are internally shorted in STP.
Otherwise, no additional wiring or wiring changes are required.
4.The substitute product in column (3) is H2C-F Motor Timers with top screw terminals because Timers with socket wiring do not have a function for separate motor and clutch connection.
STP socket wiring and H2C-F top wiring are irrelevant and so a large change in wiring is required.
The mounting method also must change from STP sockets to DIN track or screw mounting.
5.The substitute product in column (4) is the electrically reset H2C-8R Motor Timers.
It is recommended that the socket is changed to P2CF-08 for a surface mounting timer. If you continue to use 8PFA Sockets, it must be used with sY92F-42 Adaptors, and sPL08 Sockets with Y92H-1 Hold-down Clips.
When using a flush mounting model, Y92F-70 Flush Mounting Adaptors are required because H2C is smaller than STP.
