3 INSTALLATION AND WIRING

FIG.2

3.1.1 It can be installed at the height of 2 - 3m, it’s recommended to
install it at the height of 2.5m to gain the optimal detection
pattern, the detection range can reach up to the diameter of
20m and cover 360

o

detection angle (See FIG.2).

3.1.2 Pay attention to the walking direction in the test proceeding.
It is more sensitive to movement across the detector and less
sensitive to movement directly toward to detector which will
reduce the detection coverage (See FIG.3).

INSTRUCTION MANUAL

Installation and assembly of electrical equipment must
be carried out by qualified electricians.
Contact a qualified electrician in the event of fault or
break down.

A circuit breaker (250VAC, 10A) type C according to
EN60898-1 of loadⅠshall be installed in the fixed wiring
for protection.
A circuit breaker (250VAC, 6A) type C according to EN60898-1
of loadⅡ(CH2) shall be installed in the fixed wiring for
protection.
Do not mount on conductive surface.
Do not open the enclosure frequently.
Turn off power when change the light sources.
High in-rush current would occure when bulbs of certain
brands burned which might damage the unit permanently.

CAUTION!

1 PACKAGE CONTENTS

PMSCF20 is a ceiling mount PIR detector. The load will be
switched on automatically when the movement is detected and
the ambient light level is below the Lux setting value; Until there
is no movement detected and the pre-set delay time has been
expired, load will be switched off automatically. User can pre-set
the desired Lux and Time values by VR setting for automatic
control lighting on / off with low initial cost and great energy
saving potential. PMSCF20 is also be used in many different
places for HVAC control. They can be widely used in home,
office, conference room, hotel, corridor, underground parking
lots, eaves, etc.

Please disconnect power completely and read the entire

3.4 Installation procedure

3.4.1 Ceiling flush mounting

3.2.2 ON / OFF delay function

According to the changeable ambient light level, detector can
postpone load’s delay time of turning on and off to avoid load’s
unnecessarily turning on or off due to rapid ambient light change:
Ambient light level changes from bright to dark: If the ambient
light level keeps be lower than the preset Lux value for 10sec, the light
will be automatically switched on after 10sec. (LED will be on 10sec
for indication)
Ambient light level changes from dark to bright: If the ambient
light level continuously exceeds the switch off Lux value for 5min, there
are different reactions according to the time setting value.
Time setting 5min, the light will be automatically switched off after
5min.
Time setting < 5min, the light will be automatically switched off when
the set time reached if no movement is detected during the 5min. But
if there is movement detected within the 5min, the time will be reset
upon detection and until 5min later, the light is switched off.

<

Under the light on status, the light can be manually switched off by
short pressing ( 1sec) the push button. During this operation mode,
once the detector is triggered by movement, the light keeps off within
the set switch off delay time. Until there is no movement detected and
the pre-set switch off delay time has reached, the detector resumes to
work according to the previous operation mode set by knobs.
To press the push button ( 1sec) during the light manual off period
will activate the manual light on function (working as the Case 2).

An additional push button can be connected between terminal R and
L for manual on / off operation (case 1: on → off; case 2: off → on).
While pressing push button ( 1sec):

3.1.3 Helpful tips for installation

Avoid aiming the detector toward the objects which may be swayed
in the wind, such as curtain, tall plants, miniature garden, etc.
Avoid aiming the detector toward the objects whose surfaces are
highly reflective, such as mirror, monitor, etc.
Avoid mounting the detector near heat sources, such as heating
vents, air conditioning, vents as dryers, lights, etc.

Since the detector is in response to temperature change, please avoid
the following conditions (See FIG.4-A & FIG.4-B):

4.3.1 PMSCF20 has provided 2 lens shields for masking the undesired
detection area. Each lens shield has 3 layers (Layer A / Layer B
/ Layer C), each layer includes 6 small segments and each small
segment can cover 30° detection angle. For example, to install
the detector at the height of 2.5m, the detection range can
reach up to 4m diameter if the complete lens shields has been
used, and up to 8m diameter if layer C has been cut, as well,
up to 14m diameter if layer B also has been cut, the detection
range can reach up to 20m diameter when no lens shield is
used.

4.3 Usage of lens shield

Problem Possible cause Suggested solution

Lighting
device
does not
turn on

1. Power does not
turn on.

2. Wired incorrectly.

3. Lux knob adjusted
incorrectly.

4. Malfunctioned
load.

1. Switch on the power.

2. Refer to wiring diagrams for
correct connection.

3. Check if Lux knob is set to
the correct position.

4. Replace the disabled load
with a new one.

Lighting
device
does not
turn off

1. Auto off time is
set too long.

2. Detector is
nuisance
triggered.

3. Wired incorrectly.

1. Set auto off time to a shorter
time and check the load is
switched off or not according
to the pre-set off time.

2. Keep away from detection
coverage to avoid activating
detector while doing the test.

3. Make sure load and wires
are connected correctly.

LED does
not turn
on

1. Time konb is not
set to Test.

2. Exceeding the
detection range.

1. Time knob must be located
to Test position.

2. Walk in the effective detection
range of 20m diameter.

Nuisance
triggered

There are heat
sources, highly
reflective objects or
any objects which
may be swayed in
the wind within the
detection coverage.

Avoid aiming the detector
towards any heat sources, such
as air conditionings, electric
fans, heaters or any highly
reflective surfaces. Make sure
there are no swaying objects
within the detection coverage.

4.3.2 Fixing lens shield: There is circular hook on the back of the
decorative frame and the lens shield is designed with a circular
groove. The lens shield can be fitted by joining the groove of
lens shield with its corresponding hook on the decorative frame
(See FIG.13).

FIG.12

FIG.14

FIG.13

4.4 Walk test

The purpose of conducting the walk test is to check and adjust the
detection coverage. Set Time knob to “Test”, then conducting a walk
test and Lux is disabled.

It takes approx. 60sec for detector to warm up after power is
supplied, then enters into normal operation to conduct a walk test.

NOTE

4.4.1 Tester must be within the detection coverage.

4.4.2 Switch power on.

4.4.3 PMSCF20 takes approx. 60sec to warm up with load and LED
on, then turns off after warming up time.

4.4.4 Walk from outside across to the detection pattern until LED
turns on for approx. 2sec then off, the next trigger should be
2sec interval (See FIG.14).

4.4.5 Adjusting lens shield for desired detection range.

4.4.6 Repeat step 4.4.4 and 4.4.5 until it meets user's demands.

NOTE

When the actual light level is out of the range 10 - 2000Lux,
detector will learning 25sec, then the red LED flashes quickly for
5sec. When the actual light level is below 10Lux, Lux value is set
to 10Lux, or is above 2000Lux, Lux value is set to

∞

(uncontrolled by lux setting).
Installer should be away from the detector to avoid affecting the
luminous flux that reaches the detector when learning Lux value.
