- control for lighting system in locations with large
areas of accessable metal

Description:
By pressing button S1 it is possible to switch-on and
switch-off the light fitting E1 through the electronic step List of components:
relay K1. K1 = electronic step relay
Unlike electromechanical step relays, if the supply type 13.01.8.230.0000
voltage is lost then the contact of relay K1 opens. With
the supply restored, a further press of the S1
push-button is required to re-operate the light.
This step relay is provided with a separated extra low E1 = light fitting
voltage (SELV) control circuit that is electrically isolated S1 = push-button, normally open
from the supply circuit and from the power contact (Ui
4000 V). This is thanks to a high security transformer
inside the relay, built in accordance with norm EN
61558. This feature makes this product useful for the
installation of control push-buttons in areas or rooms
exposed to a high risk of electrical shock - in
accordance with limitations of norm EN 60364

Description: List of components:

As soon as the 24v control circuit powers up, timer K1
K1-K5 = relay type 40.31.8.024.0000 +
(set for DI function) energises and in turn applies a short
socket type 95.03 +
pulse to the coil of step relay K2 (equal to the time
timer module
setting for K1). This changes the state of step relay K2
type 86.30.0.024.0000
contacts, so that the motor now ready for duty is the one
that was previously off duty.
K2 = step relay
Timer K5 is set for “On Delay” (AI) and inhibits either
type 20.23.8.024.4000
motor being started during a short time period
following powering up the control circuit (K5 time must
be set slightly greater than K1). K3-K4 = miniature power relay
After the expiry of K5 set time, the motors are turned on type 56.34.8.024.0000 +
and off by miniature power relays K3 and K4, which socket type 96.04 +
are under the On/Off control of S1, with the duty being LED module/varistor
determined by the state of the contacts of K2. type 99.02.0.024.98
Every time S1 opens, the supply to K3 and K4 is cut
and the supply to the motor on duty is removed. At the M1-M2 = three-phase motors
same time, power is re-applied to timer K1 which
repeats the timing cycle that pulses the step relay K2,
which in turn changes the motor duty ready for the next
closure of S1.

Description: List of elements:

When contact S1 closes it energises the timer K1 set for K1-K2 = modular timer
cyclic function (SW). This applies power to the light type 80.01.0.240.0000
dependent relay K3, and energises the electric valve
Y3 such that the water jets associated with Y3 are now
perminantly playing.
During it’s “on” time, K1 applies power to timer K2 K3 = modular light dependent relay
which is also set for cyclic function, but for a time type 11.71.0.024.0000
approximately 25% of that for K1.
The cycling CO contact of K2 ensures that, additional
to Y3, the water jets associated with valves Y1 and Y2 E1-E2 = light fittings
play cyclically during the “on” time of K1. S1 = switch
At dusk the light dependent relay K3 causes the Y1-Y2-Y3 = electric valves
introduction of the illumination of E1 and E2.

Control of lighting by time switch and light dependent relay.

Examples of applications:
- energy saving lighting system

Description: List of components:

The light fitting E1 switches on under the control of a K1 = modular light dependent relay
contact of time switch P1. At dusk the light dependent type 11.01.8.230.0000
relay K1 switches on lighting fitting E2.
At the end of the time set by time switch P1, both
lighting fittings E1 and E2 will switch off.
P1 = digital electronic weekly time switch
type 12.21.8.230.0000

Control of lighting using a PIR movement detector.

Examples of applications:
- garage, junctions, entrances

Description: List of components:

When movement detector SP1 detects movement in a SP1 = movement detector
room, it will close it’s output contact and activate light type 18.01.8.230.0000
E1.
A light dependent sensor in the movement detector can
be adjusted to detect movement only when the ambient
light intensity is below a specific level. E1 = light
The light will be switched on only for the duration of the
time set on the movement detector – after which it resets
ready for the next detection of movement.

Control of light dimmer by push-button or remote control.

Examples of applications:
- lighting in homes

Description: List of components:

A Short press of the remote control CR, or switch S1, D1 = regulatable step relay – dimmer
will alternately switch the Dimmer D1 On or Off – type 15.51.8.230.0400
changing the state of the light E1.
Longer operation of CR or S1 will ensure that the light
level is progressively raised or lowered through a CR = remote control contact
maximum of 10 steps.
E1 = light
It is important to note that lights must conform to the
S1 = push-button
technical requirements for the dimmer, as detailed in
the Instruction manual for the dimmer.

Control of mechanized roller shutter by push-button or remote control.

Examples of applications:
- homes
- shops

Description: List of components:

Momentarily pressing the remote control causes contact
K1 = step relay
CR1 to momentarily close - pulsing the coil of step relay
type 26.08.8.230.0000
K1. The contacts of K1 control the power to motor M1.
Successive pulses to K1 will result in the contacts of K1
changing in a sequence that will drive the roller shutter
CR = remote control M1
sequentially; Up – Stop – Down – Stop - Up and so
M1 = single-phase reversing motor
forth.
S1 = push-button
The motor/shutter mechanism should be fitted with
internal end of travel limit switches to disconnect the
power to the motor when the fully Up or fully Down
positions have been reached.
However, pressing the remote whilst the shutter is
moving allows the shutter to be stopped at any desired
intermediate position.
Push-button S1 may be used to perform the same
function as the remote control.

Control of lighting using a movement detector and a timer.

Examples of applications: List of components:

- lighting of premises, classrooms K1 = modular timer
type 80.41.0.240.0000
Description:
When detector (SP) senses movement within the room it
triggers timer K1 (set for signal Off delay – BE) which
switches on light E1. SP = movement detector
The light will switch off only after; movement ceases to type 18.01.8.230.0000
be detected, the time set for SP has elapsed, and the E1 = light
time set for K1 has elapsed.
If the detector re-registers movement before the total
time delay has expired, then E1 will remain switched
on and the time will be reset.
Note: the Off delay incorporated in the 18.01 can be
set to 12 minutes maximum. Consequently for a total
time of 12 minutes or less, it is possible to utilize just the
18.01 detector.

Control for manual or automatic operation of a hydraulic pump using a

level control relay.

Examples of applications:
- house heating systems, plumbing

Description: List of components:

Pressing button S1, pulses relay coil K1, changing the K1 = modular step relay
status of its contacts; powering up level control relay K4 type 20.23.8.230.0000
and time-switch P1. In this situation, automatic control
of pumps C1 and C2 is achieved according to the level
of the hydraulic liquid, and the time of day. K2 = modular step relay
By pressing S1 again, K1 changes the status of its type 20.28.8.230.0000
contacts and switches on K3; a contact of which
powers indicator light E1 which indicates “manual
operation”. The other contact of K1 enables a feed to

the coil of K2, via push-button S2.
type 48.52.8.230.0060
Consequently, successive pushes of S2 will alternately
turn pumps C3 and C4 On or Off - via the
contacts of K2. K4 = level control relay
