C.P. Electronics MWS1A-C-PRM-LV Manual de usuario
Overview
The MWS1A-C series of microwave presence detector
switches are designed to provide automatic control of
lighting, heating or ventilation loads. The MWS1A-C
detects movement using a highly sensitive microwave
detector. This works by emitting low power microwave
signals and measuring the reflections as the signals
bounce of moving objects. The MWS1A-C is optimised for
ceiling mounting applications to give detection over long
distances.
When movement is detected the load is turned on. When
an area is no longer occupied the load will switch off after
an adjustable time out period.
The internal light sensor provides additional energy saving
in lighting applications. When an area is occupied lighting is
only switched on when the level of natural light is below a
preset level.
Three variants are available
MWS1A-C-PRM Mains voltage, switched live contact
MWS1A-C-PRM-VFC Mains voltage, isolated changeover
contact
MWS1A-C-PRM-LV Low voltage, isolated changeover
contact
Features
Microwave Sensor
Detects movement within the unit’s detection range,
allowing load control in response to changes in occupancy.
IR Receiver
Receives control and programming commands from an IR
(infrared) handset.
Light Level Sensor
An integral adjustable photocell allows the lights to be kept
off if there is sufficient ambient light.
Presence detection
When movement is detected the load will automatically turn
on. When the area is no longer occupied the load will
automatically switch off after an adjustable time period.

To switch from more than one position simply wire two or more units in parallel to achieve two way and intermediate
switching.
The detector should be sited so that the occupants of the room fall inside the detection pattern shown overleaf, at a
recommended height of 2.8m for ceiling mounted sensors. Note that the higher the sensor is installed the shorter the
detection range will be.
Do not site within 1m of any lighting or ventilation equipment.
Do not fix to a vibrating surface.
Site as far away as possible from the surface of metal objects.
Back box Compatibility Mounting
The MWS1A-C is designed to fit both UK and EU style
backboxes.

What if the load does not turn ON?
Check to see if the live supply to the circuit is good. For the MWS1A-C-PRM version only: strap across the L and
LIVE OUT terminal to turn the load on.
If the supply and wiring are good, check the LUX level setting. Increase the LUX level setting to allow the
controller to turn on at higher ambient natural light level.
What if the load does not turn OFF?
Ensure that the area is left unoccupied for a greater time period than the time out period set using the switch.
Make sure that the sensor is not adjacent to vibrating surfaces or objects (e.g. ventilation equipment).
The unit may pick up movement through thin partitions or ceilings. Reduce the sensitivity.

9 2, 5 & 7 4, 6 & 9 Lux level setting to prevent the luminaires
being switched on if the ambient light level
is sufficient (adjustable between 1

switched on at level 9.
Lux off level
(Switch

9 2, 5 & 7 4, 6 & 9 Lux level setting to switch the luminaires off
during occupancy if the ambient light level
goes above the setting (adjustable between
1 and 9). Level 9 will always keep the lights
on. This setting can be used for “window
row switching”.
Sensitivity 9 1, 5 & 9 3, 6 & 8 Sensitivity level for detecting movement.

The functionality of the MWS1A-C is controlled by a number of parameters which can be
changed or programmed by any of the following devices:
UHS5 Infrared Handset. See below for programmable functions.
UN-LCDHS Infrared Handset (with LCD). See user guide for full programming details.
For most basic programming operations the UHS5 handset can be used and the following
procedures are based on using this device.
Point the handset at the Sensor and send the required programming commands to the unit
as shown below.
Valid commands will be indicated by a red LED flash. See page 1 for details of other LED
responses.
Note: other functions on the UHS5 which are not shown below are not applicable to this
product.
