Introduction
These installation and user instructions cover
all solar variants in the 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.
Installation
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.

Fixed off between 20:30 & 01:00
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 calendar 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
center point. This center point equates to the
Greenwich Meridian (or 0
°
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
center.
To assist setting, each slot is marked with 15
minute divisions.
Locations EAST of Greenwich Meridian
– move pins ANTI-CLOCKWISE.
Locations WEST of Greenwich Meridian
– move pins 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, i.e. 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 center shaft. Refit
dial screw (B) . Turn dial in direction of the
arrow until pointer P indicates correct time.
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.
3. Models Q551.14 & Q553.14 - (DEFAULT
24:00) - Move Pin already fitted on Midnight
Bridge (S) to required setting.
4. Models Q550.13, Q551.13 & Q553.13 -
Transfer Pin (N) to Midnight Bridge (S).
Unscrew & Transfer the Operating pin (N)
from operating arm (A) onto the midnight
bridge (S), to enable a fixed off to be set as an
alternative to sunrise.
Note orientation of Operating pin prior to
transfer & ensure when re-positioned it is
securely fixed using screw and will operate
the outer lever mechanism.
5. Midnight bridge (S) is calibrated in 15
minute intervals. Set Operating Pin at any
time between 20.30 & 01.00, however see
point 6.
6. For correct unadjusted all year operation
of the Sunset operating arm (K) and the fixed
Q553
Q550
Q551
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.
