MWS5 (standard & slim-line PSU)

Miniature Microwave Presence Detector (luminaire fitting)

Overview

The MWS5 series of miniature microwave presence detectors provide automatic control of lighting loads with optional manual control. As microwave radiation penetrates plastic and glass, this unit has been specifically designed to be mounted inside a luminaire.

Three models are available: premium, direct dim, and analogue dim all of which will switch incandescent, fluorescent and compact fluorescent lighting. The direct dim variant controls DALI or DSI digital dimming ballasts whilst the analogue dim variant controls 1-10V dimming ballasts.

The unit detects movement using a microwave sensor and turns the load on. When an area is no longer occupied the load will switch off after an adjustable time out period.

A selection of fixing clips to allow the unit to me mounted in or to the side of a luminaire are available.

All functionality is fully programmable using an IR handset.

Where space is at a premium the slim-line power supply is compact and suitable for luminaire mounting where a 2A relay is sufficient. This power supply does not have connections for external switches.

Detection diagram

Please note that these approximate distances will apply with the sensitivity set to maximum.

Installation

The detector should be sited so that the occupants of the room fall inside the detection pattern shown opposite). Please note that when ceiling mounting, the recommended ceiling height of the sensor head is 2.4m.

 Avoid direct sunlight entering the sensor.

 Do not site within 1m of forced air heating or ventilation.

 Do not fix to a vibrating surface.

 Avoid metallic objects directly in front of the sensor head.

 Do not fit to a suspended luminaire.

Sensor functionality

Detection mode

 Presence 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.

 Absence (standard power supply only) The load is manually switched on. When the area is no longer occupied

the load will automatically switch off after the adjustable time period has elapsed.

 Switch operation:

PRM single switch: short press turn on, long press turn off.

MWS5-DD & MWS5-AD single switch: short press turn on, short press turn off, press and hold cycles dimming.

MWS5-DD & MWS5-AD two way switch: up button short press turns on, press and hold to dims up. Down button short press turns off, press and hold dims down.

In either case, sensitivity to movement of the microwave sensor can be adjusted using the Sensitivity parameter.

HINT: To assist in setting the Sensitivity, turn on the Walk Test LED which will flash red when movement is detected.

Switch Level On/Off

Occupancy detection can be made dependant on the ambient light level using the Lux On Level and Lux Off Level parameters.

Maintained Illuminance (daylight harvesting) - DD and AD variants only

The detector measures the overall light level in the detection area and calculates the correct output for the luminaires, to achieve a preset lux level (maintained illuminance or daylight harvesting).

Burn-in - DD and AD variants only

 Overview

It is a requirement of many fluorescent lamp manufacturers to have the lamps on at maximum output for a period of time to guarantee lamp life (refer to the manufacturer’s datasheet for details). As the MWS5-DD & AD are able to dim the lamps using DALI/DSI or 1-10V, the products provide a facility to disable this for a given period of time.

 Operation

By setting the “Burn in” parameter, you can select a time during which the lamps are not allowed to deviate from

maximum output. The unit counts the time, and even remembers how long has elapsed in the event of a power failure. To cancel the burn in function, simply select a time of 0. Note that when the lamps are changed, the burn in time should be set again.

Installation

Surface mounting using the base plate

Use the base plate for surface mounting.

Side mounting with extender

Use the extender for side mounting on a luminaire.

Readback function (only with UNLCDHS handset )

The UNLCDHS has the ability to read back the settings stored in a device.

To read back individual parameters

 Navigate to the parameter and press the ‘R’ (Read) button whilst pointing at the device. The handset will click

when the parameter has been read back, the device will flash its LED, and the value will be shown against the parameter in the menu.

To read back all of the parameters in a menu

 Press and hold the ‘R’ (Read) button for more than 1 second.  The handset will click every time a parameter is received  The device will show multiple flashes of its LED  All of the values will be shown against the parameters in the menu.  The individual parameters may be edited and then saved as a ‘Macro’.

Notes

 If a parameter(s) has been missed because of a communication error, the missing value(s) is replaced by dashes.  When reading back, the Channel 1 relay (where fitted) will temporarily be switched off, and will return to it’s

normal state 2 seconds after the read back has been completed.

Power-up test procedure

When power is applied to the unit, the load will turn on immediately. Set the timeout to 10 seconds, vacate the room or remain very still and wait for the load to switch off . Check that the load switches on when movement is detected. The unit is now ready for programming.

Fault finding

What if the load does not turn ON?

 Check that the live supply to the circuit is good.  Check that the load is functioning by bypassing the sensor (e.g. link terminals L and L/ Out).  If the detection range is smaller than expected, check the diagram on page 2. Rotating the sensor slightly may

improve the detection range.

HINT: The Walk Test LED function can be used to check that the unit is detecting movement in the required area.

What if the load does not turn OFF?

 Ensure that the area is left unoccupied for longer than the Time Out Period.  Ensure that the sensor is not adjacent to circulating air, heaters or lamps.  The unit may pick up movement through glass, thin partitions or walls and “false trigger”. Reduce the sensitivity

using the sensitivity settings .

Wiring diagrams - standard power supply

Wire the products as shown in the diagrams. All switches are optional, however the dimming variants can have two switch configurations. If used with Option A, a single momentary switch can be used for absence detection and dimming up/down—set switch mode 1 position switch together (see page 10). If used with Option B, a centre biased momentary switch gives the benefit of having separate switches to dim up and down—set switch mode 2 position switch together in this case.

Note. Due to the proximity to other terminals ,the low voltage supply (AC or DC) cannot be SELV if the output connections are mains (ie, non SELV).

Basic programming - PRM, DD and AD variants

The functionality of the MWS5-PRM, DD & AD are 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.  UNLCDHS 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.

When set to On this causes a red LED to flash on the sensor when it detects movement. Use this feature to check for adequate sensitivity levels.

Once the detector is turned on, this value sets how long the lights will stay on once movement has ceased. Select 0 for 10 second delay – use for commissioning only.

When a manual operation occurs, either via the switch input or the infrared, it invokes the timeout period. Example 1: a detector in presence mode has a detector timeout of 15 minutes and a manual timeout of 3 minutes. W hen the user leaves the room they press the off button. The sensor will revert to automatic after 3 minutes, and then walking back in the room will turn the lights on. Example 2: using the settings above, the user turns the lights off (say for a presentation) but stays in the room. Every time a movement is detected, the manual timeout period is re-triggered, but when it doesn’t pick up for the short timeout period, the sensor will timeout and revert to automatic. This means the lights may turn on inadvertently during the presentation, if the occupants are still for the manual timeout period, so adjust the timing carefully. Sensitivity level for detecting movement when the detector is already on. *UHS5

sets Sensitivity On and Off to the same value.

Sensitivity level for detecting movement when the detector is off. *UHS5 sets Sensitivity On and Off to the same value.

If the detector measures the lux level and decides that the output needs switching on or off as a consequence, the lux time must elapse first. If at any time during the timed delay the lux change reverses then the process is cancelled. Lux Time enables absence detection to be implemented with a lux off level set. When the button is pressed, the lights will go on, regardless of ambient light level. However, if there is sufficient ambient light, they will turn off again after the Lux Time. Note

that whenever the an external switch is pressed, whether in absence or presence mode, if the lights were out because of the lux level, they will be immediately turned on again for at least the Lux Time.

Select No for a 30 second delay on start up. If Yes is selected, there will be no delay on start up and the detector will always power up detecting.

The On Delay to allows the first channel to switch on after the second channel. A typical application for this would be where a detector is controlling lighting and air conditioning in an area. When the occupant is detected, the lighting will be turned on immediately, whereas the air conditioning may be turned on after 15 minutes. If the area is vacated and the detector times out before the delay, then the air conditioning would never go on. The delay can be set only for channel 1 using the on delay parameter.

Dimming output level when switched on (0-99).

Dimming output level when switched off (0-99). If a non-zero off value is set, then the output will toggle between this value and completely off depending on the switch level on and off values. For example, if it is light outside, the fittings will be off if there is no occupancy. If it is dark outside, they will adopt the preset off value.

This feature is only enabled if ‘Min value’ is set to 99.

Determines how long the output will be at 100% so that lamps ‘burn-in’. The ’burnin’ time is not affected by power supply interruptions.

After occupancy ceases, this dimming output level is loaded for the fade time (adjustable between 0 and 99).

This is the time period (adjustable between 0 and 99 minutes) that the luminaire will be held at the fade value before turning off. A value of 0 disables the fade function.

Determines the dimming response speed after the setup time has finished.

Determines the dimming response speed during the set up time. Measured in 0.1

sec intervals. If set to 0 will disable dimming for “Set seconds” below, used if

fittings are required to warm up before dimming.

Determines how long the dimming response set-up period lasts on power-up or on setting change. This enables the desired lux level to be achieved rapidly when the lights come on, or during setup.
