5. Installation

The ELU5620 may be mounted in three different ways
– wall, panel or rail. The unit is normally wall mounted
on the base plate provided. For panel mounting
you will require the panel mounting bracket AK.305
enclosed with the ELU5620. For rail mounting you will
require a quick fixing device Part No. 907-0-071.

5a Wall or Surface Mounting

1. Remove the transparent front cover from the unit.

2. Unscrew the fixing screws in the recessed holes in
the face of the switch. Note that these are captive
screws and cannot be removed.

3. Pull the timeswitch from the base plate.

4. Secure the base plate to the wall or flat surface.

5. For mains switching (230V AC 50Hz) connect the
supply to the terminals according to the wiring
diagram, noting that a link is required between
terminals 2 and 8, this is due to the option

of having voltage free contacts (see fig 2). Refer to

(fig 3) for voltage free contacts wiring. Ensure that
all bare conductors are sleeved and that correct
polarity is observed.

6. Refit the terminal cover and plug the timeswitch
into the base plate.

7. Re-tighten the fixing screws attached to the face
of the unit to the base plate.

8. Switch on the power from the supply line.

9. The programmes and clock time can now be set.

If display was blank prior to switching on power,
allow the battery to charge for at least 2 to 4
hours prior to programming.

10. Replace transparent front cover.

5b Panel Mounting

1. Remove the base plate and terminal cover as

described for wall mounting.

2. Install the timeswitch in a 68mm square hole

previously cut in the panel.

3. Lock the timeswitch in position using the panel

6 7

mounting bracket supplied.

4. For mains switching (230V AC 50Hz) connect the

supply to the terminals according to the wiring
diagram noting that a link is required between
terminals 2 and 8, this is due to the option of
having voltage free contacts (see fig 2). Refer to
(fig 3) for voltage free contacts wiring. Ensure that
all bare conductors are sleeved and that correct
polarity is observed.

5. Re-tighten the fixing screws attached to the face

of the unit to the base plate.

6. Switch on the power from the supply line.

7. The programmes and clock time can now be set.
If display was blank prior to switching on power,
allow the battery to charge for at least 2 to 4 hours
prior to programming.

8. Replace transparent front cover.

Rail Mounting

For rail mounting use the quick fixing Part No. 907-0-071
which can be supplied as an optional extra.

6. Programming

• Five setting buttons are on the face of the unit.

• The Set button is used to sequence the module

7 8

in programming mode.

• The Day, Hrs and Mins buttons are used to set
the days, hours and minutes required.

• ON/OFF programmes can also be overridden
till the third subsequent programme change by
using the O’ride button.

• To prepare the module for programming clear the
memory by pressing both the Set and Day buttons
simultaneously until the display disappears.
On releasing the buttons the display will show
0:00 INT with the colon flashing.

6a Setting the Clock Time

• To set the clock time press the Set button briefly
and release, the display will show
flashing at the right of the display.

• Press the Day button until the black indicator
shows the desired day of the week (1-7)
i.e. Monday-Sunday.

• Use the Hrs button to set the hours followed by
the Mins button to set the minutes to the actual
clock time. Holding down the either the Hrs or Mins
buttons will achieve a rapid selection.

• If the Set button is now pressed briefly and then

8

released, the display will return to the correct time
of day with the colon flashing.

• The module is now in its operating condition
and will switch “ON” and “OFF” according to
the programmes set. To alter the clock setting
subsequently there is no need to clear the
memory first.

• Note: Pauses of 15 seconds or more during setting
the clock will result in an automatic return to the
operating condition.

0:00

with “C”

INT

• Important: After setting a clock time which falls
within a programmed “ON” period, the unit will
not switch “ON” The programmed time must
be after the current time on the clock for the
programme to be switched on. If you require
the programme to be “ON” and clock time falls
within the programmed time use the override
button which will turn on the unit until the next
programmed “OFF” sequence.

6b Planning The programmes

• A programme is a pair of ON/OFF settings which

9 10

will dictate when the load will switch “ON”
and “OFF”.

• Programmes can be set before or after setting
the clock time.

• Programmes can be carried over midnight
by programming the required “ON” time
and then “OFF” at 0:00 for the first day,
followed by an “ON” at 0:00 and the required
“OFF” time for the second day. Please refer to
the table on page 10 for the setting a programme
using this method.

10 11

3 seconds until the display shows
a flashing “1” (indicating programme 1) appearing
underneath the “ON” indicator and the day
indicator will point to day 1.

• To programme the first ON/OFF times for day 1
set the “ON” time required by pressing the Hrs
and Mins buttons separately until the desired time
is displayed. Press the Set button briefly and the
display will show
underneath the flashing “1”.
Note: INT = Interrupt and means “OFF”.

Note: Pauses of 15 seconds or more during
programming will result in an automatic return
to the operating condition.

• Programming the module for day 1 should continue
in this way up to programme eight if so desired.
Note: It is not necessary to enter all eight programmes

11 12

available to you on this day, those not required
should be left blank
by not programming any ON/OFF times on the day
you require no switching on the unit.

6d Setting Programmes – Day 2, 3 etc.

• If the display still shows a day 1 “ON” or “OFF”
programme press the Day button and the day
indicator will move above day 2. If, instead, the
display shows the clock time with the colon
flashing press the Set button and hold down for
about 3 seconds until the display shows the first
programme “ON” time for day 1.

and the programme 2 “ON” time

(––:– –). You can also day omit

• Press the Day button again briefly and the day
indicator will move above day 2. In either case the
display will change to with a flashing 1
(indicating programme 1 on day 2) appearing
underneath the “ON” indicator.

• The required programmes can now be set for day
2 in the same way as for day 1. Days 3 to 7 can be
programmed in the same way as for days 1 and 2.

• Once the programming is complete press the Set
button and hold down for about 3 seconds until
the display returns to the correct time of day

12 13

with the colon flashing. The module is now in its
operating condition.

6e Suspending programmes

• Press and hold down the Set button for about
3 seconds until the first “ON” programme,
day 1 is displayed.

• Press the Day button repeatedly until the day
indicator points to the day on which you wish
to suspend the ON/OFF time.

• Press the Set button repeatedly until the “ON”
or “OFF” time of the programme you wish to
suspend is displayed.

• Press the O’ride button. A black “X” will appear
indicating that both the “ON” and “OFF” times
for this programme have been suspended until
reinstatement by the user. There is no limit to the
number of programmes you can suspend.

• To reinstate a suspended programme return to
either the “ON” or “OFF” time of the programme
which has been suspended and cancel the black
“X” by pressing the O’ride button. The ON/OFF
programme will now operate on the selected day.

7. Overriding The Module

13 14

To override the programme in operation, and to
immediately switch the device ON or OFF, simply
press the O’ride button. The display will change from
“ON” to flashing “INT” or vice versa. The override
automatically cancels when the third subsequent
programme change occurs.
