**MT-W...M** time relays 

**==> picture [41 x 40] intentionally omitted <==**

## **Time functions** 

**F0 – OFF** - Constant service off. 

F0 function can be turned on at any time, during feeding the time relay with Un voltage. Turning on F0 function during carrying out any time function will cause the function to stop as well as constant operating relay R off (LED diode ”R” is off). Function F0 is activated by pressing ”F/T” button for a longer time (more than 2 seconds) and selecting F0 function. Confirm this function with red button ”OK” (after confirmation display will show digit 0). Exiting the service function needs a longer pressing of ”F/T” button - until the display stops showing F0 function symbol. Next, after a short time, display will show ”End”. Going back to the function previously carried out is done by turning off feeding voltage Un and turning it on again. If the ”T/F” button is being pressed for too long and it will cause, after turning off F0 function symbol, showing the symbols of other functions, then going back to the function previously carried out (set before F0 function) is done by turning off feeding voltage Un and turning it on again. 

## **F1 – ON** - Constant service on. 

F1 function can be turned on at any time, during feeding the time relay with Un voltage. Turning on F1 function during carrying out any time function will cause the function to stop as well as constant operating relay R on (LED diode ”R” is on). Function F1 is activated by pressing ”F/T” button for a longer time (more than 2 seconds) and selecting F1 function. Confirm this function with red button ”OK” (after confirmation display will show digit 1). Exiting the service function needs a longer pressing of ”F/T” button - until the display stops showing F1 function symbol. Next, after a short time, display will show ”End”. Going back to the function previously carried out is done by turning off feeding voltage Un and turning it on again. If the ”T/F” button is being pressed for too long and it will cause, after turning off F1 function symbol, showing the symbols of other functions, then going back to the function previously carried out (set before F1 function) is done by turning off feeding voltage Un and turning it on again. 

**F2 – Es** - ON delay with the control contact S. 

**==> picture [70 x 31] intentionally omitted <==**

Feeding voltage U has to be put onto time relay in a constant way (LED diode ”U” gives constant light). Turning off controlling contact S starts measuring the set time T1 (display shows a vertical strip spinning to the right). When T1 time is finished operating relay R turns on (display shows ”End”, LED diode ”R” is on). Such state lasts until the moment of opening control contact S. Opening the control contact S causes immediate turning off the operating relay R (display still shows ”End”, and LED diode ”R” is off). When the control contact S is open before T1 time is finished, the operating relay will not turn on and the measurement of T time will be cancelled. 

**F3 – E** - ON delay.

If during measuring T1 time control contact S is closed, measuring of T1 time is stopped for the time of closing contact S (display shows two horizontal strips). Opening of control contact S resumes measuring of T1 time (display shows a vertical strip spinning to the right). After finishing measuring T1 time the operating relay R turns on and stays in this state until feeding U is turned off (display shows ”End”, and LED diode ”R” is on). 

**F4 – E(r)** - ON delay with the Reset function. 

**==> picture [68 x 31] intentionally omitted <==**

After opening contact S T1 time is measured from the start. After measuring T1 time operating relay R turns on (display shows ”End”, and LED diode ”R” is on). and this state lasts until the moment of turning off feeding voltage U or when the control contact is closed again. 

**F5 – R** - OFF delay with the control contact S. 

**==> picture [71 x 31] intentionally omitted <==**

Time relay input is powered by voltage U in a constant way. Closing the control contact S causes immediate turning on of the operating relay R (display shows two horizontal strips, LED diode ”R” is on). Opening the control contact S starts measuring of the set T1 time (display shows vertical strip spinning to the right). After measuring T1 time the operating relay turns off (display shows ”End”, and LED diode ”R” is off).

After measuring T1 time the operating relay R turns off display shows ”End”, and LED diode ”R” is off). Opening and closing the control contact S during measuring T1 time does not affect the function being carried out. Turning on the operating relay R again is possible (after measuring T1 time) by another closing of control contact S. 

**F9 – Wa** - ON for the set interval triggered with the control contact S. 

**==> picture [70 x 31] intentionally omitted <==**

Time relay input is powered by voltage U in a constant way.

**==> picture [70 x 31] intentionally omitted <==**

Time relay input is powered by voltage U in a constant way. Closing the control contact S causes immediate turning on the operating relay R (display shows two horizontal strips, and LED diode ”R” is on). Opening the control contact S starts measuring the time T1 (display shows a vertical strip spinning to the right), and after measuring is finished the operating relay R turns off and measuring of T2 time starts (display shows a vertical strip spinning to the left, and LED diode ”R” is off) After measuring T2 time display shows ”End”, and the operating relay R - depending on the state of the control contact S - stays off when the control contact S is open or turns on when the control contact S is closed, and LED diode ”R” goes on. 

**F14 – EWu** - ON delay for the set interval. Independent settings of T1 and T2 intervals. 

**==> picture [69 x 31] intentionally omitted <==**

Turning on feeding U starts work from measuring the time T1 (display shows a vertical strip spinning to the right), and after its completion the operating relay R starts at T2 time (display shows a vertical strip spinning to the left, and LED diode ”R” is on). After measuring T2 time the operating relay turns off (display shows ”End”, and LED diode ”R” is off). 

**F15 – WsWa** - ON for the set intervals T1 and T2 with the control contact S. Independent settings of T1 and T2 intervals. 

**==> picture [71 x 31] intentionally omitted <==**

**==> picture [33 x 7] intentionally omitted <==**

Time relay input is powered by voltage U in a constant way. Closing the control contact S turns on the operating relay R for T1 time (display shows a vertical strip spinning to the right, and the LED diode ”R” is on). After measuring T1 time the operating relay R turns off (display shows two horizontal strips, and LED diode ”R” is off). Opening the control contact S causes another turning on the operating relay R for T2 time (display shows a vertical strip spinning to the left, and the LED diode ”R” is on). After measuring T2 time the operating relay turns off (display shows ”End”, and LED diode ”R” is off). 

**a/** If during measuring T1 time the control contact S is opened, then (after measuring T1 time) the operating relay will stay on until the moment of the end of measuring T2 time. After measuring T2 time the operating relay R will turn off (display shows ”End”, and LED diode ”R” turns off) - see Diagram 1. 

**b/** If during measuring T1 time the control contact S is opened, and next, during measuring T2 time, it is closed, then (after measuring T1 and T2 times) the operating relay R will turn on for the additional T1 time. After measuring additional T1 time the operating relay R will turn off (display shows two horizontal strips, and LED diode will turn off). Such state will last until the opening of the control contact S. After opening the control contact S the operating relay R will turn on again and the measuring of T2 time will start (display shows a vertical strip spinning to the left, and LED diode ”R” is on). After measuring T2 time the operating relay R will turn off (display shows ”End”, and LED diode ”R” will turn off) - see Diagram 2.

**F16 – EWf** - ON delay and OFF delay with the control contact S. Independent settings of T1 and T2 intervals. 

**==> picture [70 x 31] intentionally omitted <==**

Time relay input is powered by voltage U in a constant way. Closing the control contact S starts measuring the time T1 (display shows a vertical strip spinning to the gight). After T1 time is finished, the relay R turns on (display shows two horizontal strips, and LED diode ”R” is on). Opening the control contact S starts measuring the time T2 - delayed turning off the operating relay R (display shows a vertical strip spinning to the left). After measuring T2 time the operating relay R turns off (display shows ”End”, and LED diode ”R” is off). 

**F17 – Wt** - Monitoring of the sequence of pulses. Switching on T2 interval is extended with consecutive pulses (closing and opening of the contact S). Independent settings of T1 and T2 intervals. 

**==> picture [68 x 31] intentionally omitted <==**

Turning on the feeding voltage U causes immediate turning on of the operating relay R fot the set T1 time (display shows a vertical strip spinning to the right, and LED diode ”R” is on). After measuring T1 time measuring T2 time starts with the operating relay R still being on (display shows a vertical strip spinning to the left, and LED diode ”R” is on) In order to keep the operating relay R on, during measuring T2 time closing, and next opening of the control contact S must occur (single impulse), which will cause resetting the time measured so far and start measuring T2 time again. If before T2 time is finished the single impulse of the control contact S does not occur, the operating relay will turn off (display shows ”End”, and LED diode ”R” will turn off). Another turning on of the operating relay will be possible after turning off feeding U and turning it on again. 

**F18 – Pi** - Cyclical operation pulse first. Independent settings of T1 and T2 intervals. Possibility of turninig on or omitting T3 time. 

**==> picture [68 x 31] intentionally omitted <==**

**==> picture [33 x 8] intentionally omitted <==**

Turning on feeding voltage U starts cyclic work from turning on the operating relay R for the T1 time (display shows a vertical strip spinning to the right, and LED diode ”R” is on), after which occurs turning off of the operating relay R for T2 time (display shows a vertical strip spinning to the left, and LED diode ”R” is off). Cyclic work lasts until the moment of turning off feeding voltage - see Diagram 1. 

**==> picture [73 x 31] intentionally omitted <==**

**==> picture [33 x 8] intentionally omitted <==**

**Note:** it is possible **to turn on T3 time** (i.e. the time of cyclic work) during programming the relay (when the LED T3 diode is flashing) by confirming it with the OK button, or omitting the T3 time by pressing ”F/T” button. When T3 time has been turned on and set, during cyclic work green LED diode T3 is flashing. After T3 time is finished display shows ”End”, LED diode T3 is off, and operating relay R remains in the state which it was in at the moment of the end of T3 time. If T3 time finishes during measuring T1 time, the operating relay R will remain on (LED ”R” is on), and if it finishes during measuring T2 time, the operating relay R will remain off (LED diode ”R” is off). Another turning on the function of cyclic work will be possible after turning off feeding U and turning it on again - see Diagram 2.

Turning on the feeding voltage U starts cyclic work from turning on the operating relay R for the T1 time (display shows a vertical strip spinning to the right, and LED diode ”R” is on), after which the operating relay turns off for T2 time (display shows a vertical strip spinning to the left, and LED diode ”R” is off). Cyclic work lasts until the moment of turning off feeding voltage U. 

**Note** : it is possible **to turn on T3 time** (i.e. the time of cyclic work) during programming the relay (when the LED T3 diode is flashing) by confirming it with the OK button, or omitting the T3 time by pressing ”F/T” button. When T3 time has been turned on and set, during cyclic work green LED diode T3 is flashing. After T3 time is finished display shows ”End”, LED diode T3 is off, and operating relay R remains in the state which it was in at the moment of the end of T3 time. If T3 time finishes during measuring T1 time, the operating relay R will remain on (LED ”R” is on), and if it finishes during measuring T2 time, the operating relay R will remain off (LED diode ”R” is off). Another turning on the function of cyclic work will be possible after turning off feeding U and turning it on again. **Operation of contact S** : closing control contact S immediately stops measuring times. Opening control contact S resumes measuring times. The break in carrying out the function Pi(S) (by the period of closing contact S) is included in T3. 

**F19 – Pp** - Cyclical operation pause first. Independent settings of T1 and T2 intervals. Possibility of turninig on or omitting T3 time.

Turning on feeding voltage U starts cyclic work from measuring the time of break T1 - the time of turning off the operating relay R (display shows a vertical strip spinning to the right), after which occurs turning off of the operating relay R for the T2 time (Display shows a vertical strip spinning to the left, and LED diode ”R” is on). Cyclic work lasts until the moment of turning off feeding voltage U - see Diagram 1.

Turning on feeding voltage U starts cyclic work from measuring break time T1 - time of turning off the operating relay R (display shows a vertical strip spinning to the right), after which occurs turning on the operating relay R for the T2 time (display shows a vertical strip spinning to the left, and LED diode ”R” is on). Cyclic work lasts until the moment of turning off feeding voltage U.

The input of the time relay is supplied with voltage U continuously. Closing of the control contact S for a shorter time than T1 time starts the T1 time, and after the T1 time has lapsed, the output relay R switches on and remains in this position until the control contact S is closed again or until the supply voltage U is interrupted. Closing of the control contact S resets the thus far measured time and starts the new T1 time. 

**F21 – Esp** - ON delay - one cycle, with closing of the control contact S.

The input of the time relay is supplied with voltage U continuously. Closing of the control contact S starts the T1 time, and after the T1 time has lapsed, the output relay R switches on and remains in this position until the supply voltage U is interrupted. When the output relay R is on, opening or closing of the control contact S does not affect its status. 

**U** - supply voltage; **R** - output state of the relay; **S** - control contact state; **T1, T2, T3** - measured times; **Ts** - pause in function performance - time measurement stop period (applies to F18 and F19); **t** - time axis
