Multifunction sensor relay for brightness,

twilight, wind, rain and frost,

5 OptoMOS semiconductor outputs

50 mA/8..230 V UC. Standby loss

without multisensor MS only 0,5 watts.

DIN rail mounted device for mounting to

DIN-EN 60715 TH35.

2 modules = 36 mm wide, 58mm deep.

The Multifunction Sensor Relay MSR12

evaluates the signals from the Multi

Sensor MS once per second, and sends

appropriate control signals

to the down -

stream EGS12Z or EGS12Z2 actuators

de-

pending on the setting of the rotary switch

on the front. The OptoMOS semiconductor

outputs switch the voltage present on

the universal voltage input terminal +B1.

One multisensor MS can only be connec-

ted to a multifunction sensor relay MSR12.

However several MSR12 can be conected

to a Multi Sensor MS, e.g. for evaluating

up to three directions with the light-sensor

of the MS.

Only one single MSR12 must provide the

outer terminal resistance. It must be remo-

ved for any further MSR12.

Supply voltage 24 V DC from the power

unit SNT12-230V/24V DC. This power

unit simultaneously supplies the Multi

Sensor MS connected to the terminals

MS1, MS2, MSA and MSB, including

heating of the rain sensor surface.

After installation wait for the short automa-

tic synchronisation of approx. 1 minute.

During this process three LEDs flash in a

slow sequence.

Function rotary switches

BA = Setting of the operation modes 1 to

10 from the adjacent chart. 2 delay times

RD - for wind and twilight - each in

connection with 5 brightness ranges for

light and twilight. The LED behind the ro-

tary switch indicates Frost at an outdoor

temperature below 2°C, at this point

output 6 is closed. This output opens

again as soon as the temperature is

above 3°C for 5 minutes.

O-S-W = If the Multi Sensor MS is aligned

towards the south, the weighting for light

and twilight can be shifted towards the

east or west. lf the MS is mounted in a dif-

ferent direction, the desired point of the

compass can be set using this rotary

switch. A LED behind the rotary switch

indicates Rain detection, at this point

output 4 is closed. Once the rain sensor

surface dries out - assisted by a heating

unit - contact 4 opens immediately. This

is automatically followed by a 2-second

pulse on output 2 if the sun signal is pre-

sent at that moment.

m/s = This rotary switch is used to se-

lect the wind speed in metres per second

at which the Wind signal is triggered.

This closes output 5. This is indicated by

the LED behind the rotary switch. Opening

takes place after the delay time RD which

has been set, during which the LED flas-

hes. This is automatically followed by a

2-second pulse on output 2 if the sun

signal is present at that moment.

DSR = In this position of the wind rotary

switch the MSR12 operates like a twilight

sensor relay. The twilight signal as des-

cribed under is then continuouslyLux

present at output 3 as long as the set

twilight value is undershot. Output 3

opens with a delay of 5 minutes if the

set twilight value is exceeded. The out-

puts 4 (Rain) and 6 (Frost) remains

active as described there. Output 5

(Wind) likewise remains active, but the

wind signal is triggered at 10m/s.

TEST = As long as 'TEST' remains swit-

ched on, each switchover from the 'OFF'

position to the 'TEST' position activates

the outputs 2 to 6 in ascending order.

OFF = In the 'OFF' position the MSR12

has no function.

Lux = This rotary switch is used to

set the

brightness at which the Sun sig nal

is immediately

triggered as a 2-second

pulse on output 2. The LED behind the

rotary switch indicates when the bright-

ness value is exceeded.

Lux = This rotary switch is used for

setting the brightness at which the 2-se-

cond Twilight signal is triggered at output

3 after the set delay time RD when the va-

lue is undershot. This is indicated by the

LED behind the rotary switch. It flashes

during the delay time. If the twilight

switching threshold is set to the same

level or higher than the sun switching

threshold, then the sun switching

threshold is raised internally above the

twilight switching threshold.

Sensor function and open circuit moni-

toring

The Multi Sensor MS sends updated infor-

mation to the MSR12 every second.

If this signal is missing completely for

5 seconds, or if the individual signal

from the wind sen sor is missing for 24

hours, then an alarm is triggered: The

wind output 5 is closed for 2 second in

order to protect any awnings or win-

dows which may be connected here.

This pulse is repeated every hour. The

wind LED flashes rapidly to signal wind

alarm. 3 LEDs flash rapidly at total sig-

nal failure. The alarm is turned off auto-

matically when a signal is detected ain.
