Zelio Time - timing relays
Functions and selection
Operating principle
Timing starts when the relay is energised. When the set time delay (t) has elapsed, the output contact closes. When the
relay is de-energised, the contact returns to its initial position. The output contact does not close if the duration of the
control instruction is less than the set time delay.
Timing can also be started by opening of a control contact (models with external control).
Energisation of the relay or closing of the control contact (models with external control) causes the output relay to close
instantaneously . Timing starts when the relay is de-energised or when the control contact opens. When the set time delay
(t) has elapsed, the contact returns to its initial position. If the energisation time or closing time of the control contact i s
less than the minimum time specified, the timing period does not start.
This function is a combination of the
On and Off delay functions. The timing
cycle must be controlled by an external
contact.
Energisation of the relay causes the output contact to close instantaneously and start the timing period. The contact
returns to its initial position when the set time delay (t) has elapsed or if the supply is cut off before the end of the timing
period.
De-energisation of the relay or opening of the external control contact (depending on model) causes the output contact
to close instantaneously and start the timing period. When the set time delay (t) has elapsed, the contact returns to its
initial position.
Energisation of the relay starts the
flashing period and causes the output
relay to start the flashing cycle. When
the relay is de-energised, the contact
returns to its initial position.
Energisation of the relay causes the star contactor to close instantaneously and starts the timing period. When the set
time delay (t) has elapsed, the star contactor returns to its initial position and the delta contactor closes, after a breaking
time sufficient for the changeover.
Symmetrical
Asymmetrical
The On and Off delays are adjusted by 2 different potentiometers.
Symmetrical flashing relay
The On and Off flashing phases are identical.
Asymmetrical flashing relay
The On and Off flashing phases are adjusted by 2 different potentiometers
(ta and tr).
The On and Off delays are equal.
