Before attempting to install the
Sangamo Time Switch, please read
these instructions carefully.
Introduction
These installation and user instructions cover
ALL SOLAR VARIANTS in the S250 & Q550
series – a range of reliable and highly accurate
24-hour solar dial time switches which offer,
according to the specific model, a range of
features suited to individual applications.
See Quick Reference Chart later.
1. The installation of this time switch should be
carried out by a qualified electrician in
accordance with current IEE wiring
regulations.
2. Sangamo cannot be held responsible or
liable for circuit connection other than those
directly associated with our products.
3. To comply with safety requirements it is
recommended that the time switch be installed
with the base provided.
4. Terminals are for fixed wiring only. Provision
must be made in the fixed wiring for a means
of disconnection from the supply having a
contact separation of at least 3mm on all
poles.
5. The time switch must be earthed.
6. This product is suitable for ‘Ordinary’
conditions only. It is not protected against
dripping or moisture and so should be housed
in a suitable IP rated enclosure.
7.
DO NOT REMOVE THE 2 SCREWS AT
REAR OF SWITCH BASE
.
8. Rotate cover anticlockwise and lift clear.
9. Remove extended terminal cover (E) by
unscrewing captive screw (F).
10. Withdraw plug-in mechanism from switch
base, by grasping & pulling firmly on the dial.
11. Clear plastic from three fixing holes
provided, removing debris.
a.Use no8 wood screws or 2BA countersunk
screws for fixing.
b.Fix with suitable wall plugs for the surface
intended.
c.When mounting the time switch on a
metal surface, ensure the metal is adequately
earthed to cover the 20A rating in accordance
with IEE Regulations.
12. Strip back insulation by 6mm to ensure
satisfactory connection with terminals.
Connect switch to supply and load as in wiring
diagrams above.
13.
For S253 and Q553:
– WHERE SEPARATE MOTOR & SWITCH
CIRCUIT SUPPLIES ARE NOT AVAILABLE
– FIT A LINK BETWEEN TERMINALS 1 & 3.
14. Connect earth lead to earth connection (T).
15. Plug mechanism into base.
16. Cut & trim breakouts in the extended
terminal cover (E) as necessary if wiring
routed on the surface. Refit extended terminal
cover (E) to base using captive screw (F).
This will lock the mechanism inside the base.
17. Follow setting instructions for the time
switch then refit cover.
It is important for accuracy the correct switch
is installed for the latitude zone in the country.
(see zone map later)
This type of dial automatically adjusts, once
set, for seasonal changes in sunset and
sunrise time during the year to suit lighting
applications. Depending on the model , fixed
operations can also be set.
1. Remove dial screw (B) and pull dial free
from the mechanism. This makes adjustment
easier.
2.
DO NOT LOOSEN SERRATED CENTRE
NUT.
3. Turn date wheel (D) in either direction,
until correct calandar position is indicated in
date aperture (C). Each month is subdivided
into six equal divisions, representing 5 days.
4. Sunset On & Sunrise Off operating arms
(K) & (A) each have an operating pin at the
centre point. This centre point equates to the
Greenwich Meridan (or 0 deg Longitude)
location in the country.
5. Adjustment for longitudinal variation can be
made by moving the operating pins (N) along
the slot on BOTH operating arms (K) & (A), up
to a maximum of +/- 45mins from centre.
To assist setting, each slot is marked with 15
minute divisions.
Locations EAST of Greenwich Meridian
– move pins CLOCKWISE.
Locations WEST of Greenwich Meridian
– move pins ANTI – CLOCKWISE.
(see zone map later)
6. Further adjustment to advance the Sunset
ON and delay the Sunrise OFF settings and
increase the overall ON time to suit darker
environment applications, ie Stairwells, may
be possible.(Depending on the longitudinal
variation used). Move operating pin (N) along
each operating arm as follows.
ADVANCE – move pin ANTI -CLOCKWISE on
the Sunset ON operating arm (K).
DELAY – move pin CLOCKWISE on the
Sunrise OFF operating arm (A).
7. Refit dial onto mechanism ensuring dial hub
engages cross-pin on centre shaft. Refit dial
screw (B) . Turn dial in direction of the arrow
until pointer P indicates WINTERTIME(GMT).
8.
DIAL SHOULD RUN SET TO
WINTERTIME THROUGHOUT THE YEAR
.
1. Remove dial screw (B) and pull dial free
from the mechanism. This makes adjustment
easier.
2.
DO NOT LOOSEN SERRATED CENTRE
NUT.
