User Instructions

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 specic 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 qualied 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 xed wiring only.
Provision must be made in the xed 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 rmly on the dial.

11. Clear plastic from three xing holes

provided, removing debris.
a. Use no8 wood screws or 2BA countersunk

screws for xing.
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 Q553 - WHERE SEPARATE MOTOR

& SWITCH CIRCUIT SUPPLIES ARE NOT
AVAILABLE - FIT A LINK BETWEEN
TERMINALS 1 & 3.

Q553

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. Ret 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 ret cover.

Setting a Solar Dial

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 , xed

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. Ret dial onto mechanism ensuring dial
hub engages cross-pin on center shaft. Ret
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.

Fixed off between 20:30 & 01:00

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 tted 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 xed off to be set as an

alternative to sunrise.

Note orientation of Operating pin prior to

transfer & ensure when re-positioned it is

securely xed 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 xed

off on the midnight bridge (S), the xed off
should be set after 22.30. Fixed off’s set prior

to this will interfere with sunset operating

arm (K) during April – September and cause

the switch to operate for a short period when
not required.

7. Ret dial onto mechanism ensuring dial hub
engages cross-pin on centre shaft. Ret dial
screw (B) . Turn dial in direction of the arrow
until pointer (P) indicates WINTERTIME

(GMT).

8. All xed times need to be adjusted for the
winter/summer clock changes to be uniform

during the year.

March – Move time setting back, i.e. 24:00 to

23:00

October – Move time setting forward, i.e.

23:00 to 24:00

Fixed early on 03:15 & 08:30

Models Q551.14 & Q553.14 (DEFAULT
05:00)

1. The adjustment is made to the rear of the

solar dial. Remove dial screw (B) and pull dial

free from the mechanism to gain access.

2. DO NOT LOOSEN SERRATED CENTRE

NUT

3. Slacken 8BA nut on underside of sector
bridge and move spring tensioned lever 2,
along sector bridge 1, until slot 4 coincides
with time required. The Sector bridge is
calibrated in 15 minutes intervals. Tighten
8BA nut.

4. Ret dial onto mechanism ensuring dial
hub engages cross-pin on centre shaft. Ret
dial screw (B) . Turn dial in the direction
of the arrow until pointer (P) indicates

WINTERTIME(GMT).

5. Fixed operation will be obtained at the
time set except in summer where the sunrise
operating arm (A) operates earlier.

6. All xed times need to be adjusted for the
winter/summer clock changes to be uniform

during the year.

March – Move time setting back, i.e. 05:00 to

04:00

October – Move time setting forward, i.e.

04:00 to 05:00

Setting Day Omit Device

Model Q550.13

1. Day omitting device (D) prevents ‘On’

operation occurring on a chosen day or days
of the week.

2. To OMIT operations on a given day, turn
insert 1 clockwise on a given day , with a

screwdriver, until ARROWHEAD POINTS

OUTWARDS.

4. Ensure dial is showing the correct time.

Note the position of the operating arm (K)
which operates the day omitting device (D)

once every 24 hours. If this operating arm has

PASSED the Day omitting device (D)
– turn black disc so the CURRENT day is set.
If this operating arm (K) has NOT REACHED
the Day omitting device (D) – turn black disc
to the PRECEDING current day.
