Instruction Manual
Time Functions
E - On Delay: After supply voltage U has been switched on, the set time T is being measured. After the T time has
lapsed, the R operating relay shall start operating and remains in operating position until the supply voltage U is
switched off.
Wu - Single shot leading edge voltage controlled. After the supply voltage U has been switched on, the operating
relay R starts immediately and the set time T is being measured. After the set time T has lapsed, the operating relay
R returns to the initial position.
Bp - Flasher pause first: After the supply voltage U has been switched on, the set time T is being measured. After
the time has lapsed, the operating relay R starts operating and the T time is being measured again. After the time
has lapsed, the operating relay R returns to the initial state, and another cycle of the relay operation commences.
The relay operates until the supply voltage is switched off.
Bi - Flasher pulse first: After the supply voltage U has been switched on, the set time T is measured and the
operation relay R is switched on. After the time has lapsed, the operating relay R starts operating and the time T
is being measured again. After the time has lapsed, the operating relay R returns to the initial state, and another
cycle of the relay operation commences. The relay operates until the supply voltage is switched off.
T - generating the 0.5s pulse after the T time.
R- OFF Delay: The supply voltage U must be constantly applied to the time relay. After the control contact S has
been closed, the operating relay R starts operation immediately. After the control contact S has been opened, the set
time T is being measured. After the T time has lapsed, the operating relay R returns to the initial position. When the
control contact S is closed again, even before the T time has lapsed, the time measured thus far is reset, and when
S is opened, the set time T is being measured again.
Ws - Single shot leading edge with control contact: The supply voltage U must be constantly applied to the
time relay . After the control contact S has been closed, the operating relay R starts immediately and the set time
T is being measured. After the set time T has lapsed, the operating relay R returns to the initial position. In course
of measuring the T time, the control contact S may be closed and opened repeatedly with no impact upon the
operating relay R. Only after the T time has lapsed, closing S will make the operating relay R operate and the T
time will be measured.
Wa - Single shot trailing edge with control contact: The supply voltage U must be constantly applied to the time
relay. Closing of the control contact S does not trigger the measurement of the time delay or operation of the
operating relay R. Only opening of the control contact S causes the immediate operation of the operating relay R,
and the set time T is being measured. After the T time has lapsed, the operating relay R returns to the initial position.
In course of measuring the T time, the control contact S may be closed and opened repeatedly with no impact upon
the output relay. Only after the T time has lapsed, closing and opening of S will make the operating relay R operate
and the T time will be measured.
Esa - ON and OFF delay with control contact: The supply voltage U must be constantly applied to the time relay.
After the control contact S has been closed, the set time T is being measured and when it lapses the operating relay
R is switched on. On opening of the control contact S the set time T is measured again, and after the time has
lapsed, the operating relay R is switched off. In case the time of closing the control contact S is shorter than the set
time delay T, the operating relay R shall start operation after the set delay has lapsed, and it will continue to operate
for the T time. In course of the operation of the R relay, closing of the control contact S does not affect the function.
B - Bistable relay leading edge with control contact.
Each closing of the control contact S changes the operating relay status to the opposite one (a feature of a bi-stable
relay).
Permanent switching ON and OFF. The functions ON and OFF are selected with the TI E potentiometer. In the
ON function the normally open contacts are closed all the time whereas in the OFF function they are open. The
position of the FUNC potentiometer is of no significance when the ON / OFF function is selected.
