Note:
• Not all Finder Step relays are available with all the
possible alternative Switching functions.
• The Switching function code generally has the same
meaning for all Finder step relays, although there are
a few minor anomalies – so in practice refer
carefully to the data sheet for the specific relay.

For example:
The Switching Function code “6” (2 pole, 3-step sequence)
can be implemented with relay types 20.26 – 26.06 – 27.06,
but the latter has coil and contact circuits that are common
to each other.

Notes
1. It is good practice to try to achieve a correct installation where the light emitted from the lamp(s) does not influence the light level seen
by the sensor, although the “light feedback compensation” principle will help when this is not fully achievable. In this case it should be
appreciated that the “light feedback compensation” principle may delay slightly the time of Switch Off - beyond the ideal.
2. The compensation principle is not effective where the combined effect of the ambient light and the controlled lighting exceeds 120 lux.
3. The 10.32 and 10.41 types are compatible with gas discharge lamps that attain full output within 10 minutes, since the electronic circuit
monitors lamps’ light output over a 10 minutes period to achieve a true assessment of its contribution to the overall lighting level.

Master & Slave Dimmers - Types 15.10 and 15.11

The Master Dimmer produces a 0 -10 V signal proportional to the required

will control the voltage applied to the lamps and therefore their brightness.

External push-button

Movement

A control pulse on the push-button inverts the status of the output relay, until the timing after the last movement detected has elapsed.

Dynamic Light Compensation

By incorporating Finder’s Patented “light feedback compensation” principle, the 18.51...0040 is able to calculate the artificial light
contributed by the lamps controlled by the output relay. In effect, this means the 18.51...0040 is able to continuously monitor the
natural ambient light level, even when the output is On. As a consequence, whenever the natural light level exceeds the threshold
setting the output is forced Off.
This can significantly minimises the time the lighting is On, particularly where there is a high level of traffic - and cost savings can be
considerable. This is an advance over other types of movement detectors, which are unable to identify the natural ambient light level
when the output is On and so can only turn Off after the time delay that follows the last detected movement. In busy areas this may
mean that the movement detector is being continuously re-triggered and maintained in the On state, even though the natural light
level has long risen above the threshold.

This shows the 72.42 Priority

change relay working in
conjunction with a single 72.01
level controller. Under normal
conditions the liquid level is
expected to remain within the
range shown as Min to Max.
In this case the function of the
72.42 will be to alternate the
duty between both pumps, to
even wear across both pumps.
There is no provision to run
both pumps simultaneously.

72 Series - Level control relays for conductive liquids

(ME) Function example

This shows the 72.42 Priority

change relay working in
conjunction with two 72.01
level controllers. Under normal
conditions the liquid level is
expected to remain within the
range shown as Min to Max.
In this case the function of the
72.42 will be to alternate the
duty between both pumps, to
even wear across both pumps.
Should the liquid level rise
above the Alarm level then the
function of the 72.42 will call
for the simultaneous operation
of both pumps, by virtue of the
signal to terminal B3 from the
Alarm/Low level controller.
Note: due to the low level of
72.42 control signals, it is
suggested to use level
controller 72.01.8.240.5002

- 35 mm rail (EN 60715) mount

Functions

(MI) Outputs alternate on successive applications of supply voltage

• Application of the supply voltage to A1-A2 forces just one
output contact to close, but the contact that closes will alternate
between 11-14 and 21-24 on each successive application of
the supply – ensuring even wear across both motors.
• The other output contact can be forced closed by the closure of
either S1 or S2 - but to limit high current surges the other motor
cannot start within T seconds of the first motor.

130
72 Series - Level control relays for conductive liquids

(ME) Outputs alternate according to control signal

• The supply voltage is permanently applied to A1-A2.
When closed, S1 forces just one output contact to close. The contact that
closes will alternate between 11-14 and 21-24 on each successive S1
closure - ensuring even wear across both motors.
• If closed, S2 forces both output contacts to close (irrespective of S1).
However, to limit high current surges, both motors cannot start within
T seconds of each other.

(M2) Output 2 (21-24) only

• Supply permanently applied to A1-A2.
• Closure of either S1 or S2 will close output contact 2 (21-24).
Use when load 1 (11-14) is out of service.

(M1) Output 1 (11-14) only

• Supply permanently applied to A1-A2.
• Closure of either S1 or S2 will close output contact 1 (11-14).

which it resets; subsequent closures of Signal Switch during the delay will extend the time. If the
closure of the Signal Switch (S) is longer than the preset time (T) then the output contact resets.

(GE) Pulse delayed with control signal on

Power is permanently applied to the timer. Closing the Signal Switch (S) initiates T1 delay,
after which the output contact transfers. Reset occurs after T2 time.

(LE) Asymmetrical flasher (starting pulse on) with control signal

Power is permanently applied to the timer. Closing Signal Switch (S) causes the output contact
to transfer immediately and cycle between ON and OFF, until opened.

(PE) Asymmetrical flasher (starting pulse off ) with control signal

Power is permanently applied to the timer. Closing the Signal Switch (S) initiates delay T1 after
which the output contact transfers and continues to cycle between OFF and ON, until the Signal
Switch is opened

84 Series - SMARTimer - Digital timer with NFC programming

Function U = Supply voltage S = External Start P = Pause = Output contact

(IT) Timing step
Closing the Signal Switch (S) the output contact transfers and remains so after S opening,
for the duration of the preset delay, after which it resets. During the timing period it is
possible to immediate open the contact with a further impulse on S.

(SS) Monostable controlled by Signal switch

The output contact follows the status of Signal Switch (S).

(PS) Monostable controlled by Pause switch

The output contact follows the status of Pause Switch (P).

(SHp) “Shower” (off-delay with control signal and pause signal)

Power is permanently applied to the timer. The output contact transfers immediately on closure
of the Signal Switch (S). Opening the signal switch initiates the preset delay, after which the
output contact resets. Closure of the Pause Switch (P) will immediately halt the timing process,
but the elapsed time will be retained. During the pause, the output contact will be open. On
opening of the Pause Switch, timing resumes from the retained value and the output contact
will take the previous condition.
