Function K
Delay on de-energisation - true delay OFF
On energisation, the output changes state.
On de–energisation timing commences and
the output only returns to the
reset condition after timing.
Function L
Cyclic timing - Asymmetrical recycler
Repetitive cycle comprising 2 independent
adjustable time bases. Each time base corresponds
alternately to a different output state.
N.B. : The cycle starts with the
output in the rest position.
Function Li
Cyclic timing - Asymmetrical recycler
Repetitive cycle comprising 2 independent
adjustable time bases. Each time base corresponds
alternately to a different output state.
N.B. : The cycle starts with the output
in the operating position.
Function N
"Safe-guard"
At the first control pulse the output is energised.
To complete the timing the interval between
the two control pulses must be greater than the timing set.
Function O
"Delayed safe-guard"
On energisation, a first timing sequence
occurs and the output changes state.
With the closing of the control contact,
the output resets and the timing starts, with
the output being activated after timing.
For the timing to be completed, the interval
between the closing of two control contacts
must be greater than the timing set.
Function P
Delayed fixed-length pulse
Timing begins on energisation. At the end
of the timing period output relay R (or the load)
changes state for a period of approx. 500 milliseconds.
Our timers are designed according to international recommendations (IEC),
American (UL), Canadian (CSA) and German (VDE) standards, European
standards (EN), etc.
Proof of compliance with these standards and recommendations is
demonstrated by approval (a symbol or certificate of conformity granted by an
accredited body) or by the manufacturer's declaration of conformity (drafted in
accordance with ISO/IEC 22 guidelines).
We have indicated the principal approvals so far obtained in the table below.
Conformity to standards is indicated in the "technical characteristics".
Machine safety
Our products are compatible with standard EN 60204-1 (IEC 201-1)
concerning the safety of electrical equipment for machinery.

Function Pt
Delayed fixed length pulse (with memory)
As function P but with memory
Function Q
Star-delta
At the end of timing, the output is not
energised. It remains "open" (not conducting)
and will only change state after the fixed
time of Ti has elapsed.
Dwell time selectable
Function T
Timing on energisation with memory
a - energisation by control signal
The timer sums the times for which the
control contact is closed (C1).
Reset is by the reset signal (C2) only.
b - energisation by supply voltage
The timer sums the times for which
the supply voltage (U) is on.
Reset is by the reset signal (C2) only.
Function T
Latching relay by control contact
After energisation, closure of the control
contact causes output relay R to energise.
A second closure of control contact
de–energises the relay.
Function Tt
Timed latching relay by control contact
As function T
contact does not occur before end of time
period, the relay will de–energise at the end
of the time period.
Function W
Timing after pulse on control contact
After energisation, if the control contact
opens it causes output relay R (or the load)
to change state and timing to start.
At the end of the timing period,
relay R resets to its original state.
