Time functions

A - OFF delay without supply voltage

When the supply voltage U is supplied, the output relay R switches into on-position (green LED U illuminated). If the supply voltage is interrupted (green LED U not illuminated), the set interval T begins. After the set interval T has lapsed, the output relay R switches into off-position. If the supply voltage is reconnected before the interval T has lapsed, the interval already measured is erased and is restarted with the next cycle.

U - supply voltage; R - output state of the relay; T - measured time; t - time axis

AUTO - ON for a set interval triggered by applying the supply voltage U or closing of the control contact S

Each application of the supply voltage U or closing of the control contact S while supply voltage U is applied results in immediate switching the R contact on for an adjustable interval T. After the T interval has lapsed, the R contact remains off. Opening and closing of the control contact S within the T interval does not affect the function to be fulfilled.

U - supply voltage; R - output state of the relay; S - control contact state; T - measured time; t - time axis 

B - Cyclical operation with the control contact S.
The input of the time relay is supplied with U voltage continuously. Closing of the control contact S immediately switches on the output relay R. Each next closing of the control contact S results in a change of the status of the output relay R to an opposite one (the feature of a bistable relay).

Bi - Symmetrical cyclical operation pulse first.

Applying the supply voltage U starts the cyclical operation from switching on the output relay R for the set interval T. After the interval T has lapsed, the output relay R switches off for the interval T. The cyclical operation lasts until the supply voltage U is interrupted.

Bi(S) - Symmetrical cyclical operation pulse first, with interval T measurement stopped for the time the S contact is switched on.

Applying the supply voltage U starts cyclical operation from measurement of the interval T - switching on the output relay R. If in the course of measurement of interval T the control contact S is closed, the measurement of the time of switching off the R relay will be interrupted for the time the S contact remains closed. Opening of the control contact S triggers further measurement of the interval T. After the interval T has lapsed, the output relay R switches on for the set interval T. If during the measurement of the interval T the control contact S is closed, measurement of the time of switching off the R relay will be interrupted for the time the S contact remains closed. Opening of the control contact S triggers further measurement of the interval T. The cyclical operation lasts until the supply voltage U is interrupted.

Bp(S) - Symmetrical cyclical operation pause first, with interval T measurement stopped for the time the S contact is switched on.

Applying the supply voltage U starts the cyclical operation from the interval T - switching the output relay R off. If in the course of measurement of interval T the control contact S is closed, the measurement of the time of switching off the R relay will be interrupted for the time the S contact remains closed. Opening of the control contact S triggers further measurement of the interval T. After the interval T has lapsed, the output relay R switches on for the set interval T. If during the measurement of the interval T the control contact S is closed, measurement of the time of switching on the R relay will be interrupted for the time the S contact remains closed. Opening of the control contact S triggers further measurement of the interval T. The cyclical operation lasts until the supply voltage U is interrupted.

When the supply voltage U is applied, the set interval T begins. After the interval T has expired (green LED illuminated) the output relay R switches into on-position. This status remains until the supply voltage is interrupted.

E(R) - ON delay with the Reset function.

Turning on the feeding voltage U starts measuring set T1 time. After measuring T1 time operating relay R turns on. If control contact S is closed during measuring T1 time measuring of T1 time is stopped for the time of closing contact S. After opening contact S T1 time is measured from the start. After measuring T1 time operating relay R turns on. and this state lasts until the moment of turning off feeding voltage U or when the control contact is closed again.

E(S) - ON delay, with time measurement stopped with contact S.

Turning on the feeding voltage U starts measuring set T1 time. If during measuring T1 time control contact S is closed, measuring of T1 time is stopped for the time of closing contact S.

In case the control contact S is closed in the course of the interval T2, the measured time is reset and the output relay R remains switched on. In case the control contact S is closed for time shorter than T1, the unit will not switch the output relay R on.

Es - ON delay with the control contact S.

The input of the time relay is supplied with voltage U continuously. Closing of the control contact S starts the interval T - on-delay of the output relay R.

The interval T measurement will start after the control contact S has been closed. After the set interval T has lapsed, the output relay R switches on. Opening of the control contact S will again trigger measurement of the set interval T - OFF delay of the output relay R, and after the interval has been measured, the output relay R switches off. If the control contact S is closed during the interval T measurement, the measured time will be reset. Opening of the control contact S will again trigger measurement of the interval T.

Time relay input is powered by voltage U in a constant way. Closing the control contact starts measuring T1 time, and after its completion the operating relay R turns on for T2 time. After the T2 time the operating relay R turns off. The system is waiting for another closing of the control contact S. During measuring times T1 and T2 the state of the contact S does not matter.

EWu – ON delay and the set interval. Independent settings of T1 and T2 intervals.

When the supply voltage U is applied, the set interval T1 begins. After the interval T1 has expired, the output relay R switches into on-position and the set interval T2 begins.

After the T interval of switching the R contact off has lapsed, the R contact is switched off. Interruption of the supply voltage U while ON-delay by the set T interval is being measured for the R contact stops measurement of the T interval and switches the R contact immediately for the set T interval; after the interval has lapsed, the R contact is switched off.  Applying the supply voltage U when the T interval is being measured for the R contact to be switched off stops measurement of the interval, switches the R contact off, and starts measurement of ON-delay for the R contact.
