A brand new bright 2-color back light LCD display. The easy-to-read screen in any location makes checking and setting procedures a cinch.
Seesaw buttons make operating the unit even easier than before.
With a short body, it is easy to install in even narrow control panels.
The water-proof panel keeps out water and dirt for reliable operation even in poor environments.
Also offers a black panel cover to meet your design considerations.

Changing the set time
Power failure memory
The EEPROM is used for power failure memory. It has a life of Min. 105 over-writings.
The EEPROM is overwriting with the following timing.
Output mode | Overwrite timing |
---|---|
Power ON delay (2) A2 | When power is OFF |
Addition G | Change of preset value or start, reset input When power is OFF after being ON |
Other modes | When power is OFF after changing preset value |
* | Be aware that the contents of EEPROM for all models will be overwritten when power is turned OFF during input to external lock terminals (4) to (3) and [7] to [6]. Such an action does not exist by doing lock operation from the front. |

Operation type | Explanation | Time chart |
---|---|---|
Power on delay (1) (A) |
Set the operation mode section of the DIP switches (no.'s 1, 2, and 3)
・Clears elapsed time value and starts time delay at power ON. ・After timer completion, stops at the display of the set value (addition), or stops at "0" (subtraction). ・Ignores start input. ・Stops delay time operation at stop ON. ・Restarts delay time operation at stop OFF. |
![]() |
Power on delay (2) (A2) |
Set the operation mode section of the DIP switches (no.'s 1, 2, and 3)
・Elapsed time value does not clear at power ON. (power outage countermeasure function) ・The output remains ON even after the power is cut and restarted. ・After timer completion, stops at the display of the set value (addition), or stops at "0" (subtraction). ・Ignores start input. ・Stops delay time operation at stop ON. ・Restarts delay time operation at stop OFF. |

Signal on delay (B) |
Set the operation mode section of the DIP switches (no.'s 1, 2, and 3)
・Clears elapsed time value at power ON. ・Time delay starts at start ON and elapsed time value or output resets at start OFF. ・Instantaneous time delay start at reset OFF and power ON while start is ON. ・Stops delay time operation at stop ON. Restarts delay time operation at stop OFF. ・In order to have the time delay start at power ON or reset at power OFF, short out the start input beforehand. |

Signal off delay (C) |
Set the operation mode section of the DIP switches (no.'s 1, 2, and 3)
・Clears elapsed time value at power ON. ・Output control ON at start ON and time delay start at start OFF. ・Elapsed time value clears when start goes ON again during time delay. ・Stops delay time operation at stop ON. ・Restarts delay time operation at stop OFF. |

1* | Each signal input (start, reset, stop, and lock) is applied by shorting their input terminal to the common terminal (terminal (1) for the 8-pin type, terminal (3) for the 11-pin type, and terminal [6] for the screw terminal type). |
---|---|
2* | The 8-pin type does not have a stop input or lock input. |
Operation type | Explanation | Time chart |
---|---|---|
Pulse One-shot (D) |
Set the operation mode section of the DIP switches (no.'s 1, 2, and 3)
・Clears elapsed time value at power ON. ・Time delay starts and output control ON at start ON. ・Turns output control OFF and clears elapsed time value at time-up. ・Ignores start input during time delay. ・Stops delay time operation at stop ON. ・Restarts delay time operation at stop OFF.
In order to have the time delay start at power ON or reset at power OFF, short out the start input beforehand. |

Pulse On delay (E) |
Set the operation mode section of the DIP switches (no.'s 1, 2, and 3)
・Clears elapsed time value at power ON. ・Time delay starts at start ON. ・Ignores start input during time delay. ・Stops delay time operation at stop ON. ・Restarts delay time operation at stop OFF.
In order to have the time delay start at power ON or reset at power OFF, short out the start input beforehand. |

Signal Flicker (F) |
Set the operation mode section of the DIP switches (no.'s 1, 2, and 3)
・Clears elapsed time value at power ON. ・Time delay starts at start ON. ・Ignores start input during time delay. ・Output control reverses, elapsed time value clears, and timer delay starts at timer completion. ・Stops delay time operation at stop ON. ・Restarts delay time operation at stop OFF.
In order to have the time delay start at power ON or reset at power OFF, short out the start input beforehand. |

Totalizing On delay (G) |
Set the operation mode section of the DIP switches (no.'s 1, 2, and 3)
・Elapsed time value does not clear at power ON. (power outage countermeasure function) ・The output remains ON even after the power is off and restarted. ・Stops delay time operation at stop ON. ・Restarts delay time operation at stop OFF. |

*1 | Each signal input (start, reset, stop, and lock) is applied by shorting their input terminal to the common terminal (terminal (1) for the 8-pin type, terminal 83) for the 11-pin type, and terminal [6] for the screw terminal type). |
