Introduction
This product combines a 7-day time switch with a daylight sensor
controller, in one unit. The time switch will accept up to eight
programme pictures for time control. Each picture is a complete LCD
display of a switching cycle, i.e. a command for the output relays to be
switched on at a set time, on one or more days, and off at a different
set time, on one or more days. The on days need not be the same as
the off days.
Figure 2 shows an example of a programme picture.This example
demonstrates overnight programmes, typical for this type of product.
Besides switching in accordance with the eight programme pictures,
the unit can be manually overridden, either temporarily until the next
opposite command, or continuously switched on or off.
A summer/wintertime changeover (±1hr) button is also available.
Additionally, a Holiday Programme facility is incorporated permitting the
unit to be switched continuously on or off for up to ninety nine days. A
3-position, manual override switch is also incorporated to provide:
Ι
output relay continuously off
output relay follows set programme
ΙΙ
output relay continuously on
The daylight sensor is housed in an all-insulated, weather resistant
enclosure (IP55) for external mounting, if required.
The main advantages of this time switch/daylight sensor combination
are:
●
All controls easily accessed, including the setting of the daylight
switching levels.
●
Single pair, low voltage wiring between the sensor and
the time switch/controller.
Installation
The time switch/controller may be snap-fitted on symmetrical DIN
mounting rail to BS 5584: 1978 (EN 50 002, DIN 46227-3) or housed in
a suitable enclosure.
Modular enclosures, permitting access to the front of the time
switch/controller, are available (see RS catalogue main index under
'DIN 43 880 equipment - housing/enclosures"). The unit must be
connected in accordance with the diagrams displayed near the
terminals.
Safety instructions
Electrical equipment must only be fitted by qualified
personnel. Ensure that the available supply voltage is within the
unit's nominal range. The output relay contacts must not be
directly used to switch low voltages (24V
and 12-24V
)
according to DIN 57 100 pt 410/VDE 0100 pt 410 section 4.1, i.e.
Safety Extra Low Voltage.
