Elkay 374C-1 Manual

The Flush Mount PIR Timer (3 wire)
is part of the Elkay family of switches,
timers and detectors which save
energy and increase convenience in
and around your home, garden
or premises.
Rating at 220-240V ac 50Hz
• All load types 6A
• Time Delay: 30secs - 30min
• Manual Lux Sensor for daylight control
Usage
The PIR sensor has been designed to switch
lighting, heating and ventilation loads up
to 6A. The unit is switched on by the
detection of moving infra red heat within
a specied range. When infra red heat, such
as a moving body, is no longer detected,
the unit will switch o the load after the
adjustable time period has elapsed.
If infra red heat is detected again during the
timing period, the timing sequence will
restart. The unit has a lux level adjustment
which measures the ambient light levels
and prevents lighting being switched on,
when there is sucient lighting in the room.
A power factor correction capacitor of 4
microfarads may be required when
switching low wattage loads, e.g. LED loads.
The capacitor is tted across switch live
and neutral supplies of suitable Elkay
capacitors can be found at your stockist
(ref. pfcc-1).
Do not insulation resistance test this
product. Remove before testing or test
circuit prior to tting.

Positioning
Careful positioning is essential to obtain
optimum performance. Use the
detection range to determine a suitable
location for the sensor. When locating
the position of the units, ensure
the sensor is not subjected to bright or
direct sunlight or in areas with high
re ective surfaces.
Diagram 2
Do not site units on a vibrating surface, or
near forced air heating and ventilation.
They should not be placed within 1 metre
of the load. Sensors work when objects
move across their  eld of view. Position the
sensor where people will be detected
walking across the zones rather than
towards the zones identi ed in Diagram 1.

Installation Steps
IT IS ESSENTIAL THAT YOU FOLLOW
CLOSELY STEPS 1 TO 7 OF THE MOUNTING
AND INSTALLATION INSTRUCTIONS
BELOW. FAILURE TO DO SO WILL
INVALIDATE THE WARRANTY.
Step 1
Please ensure that you position the PIR in
the correct place by reading the Positioning
section of these instructions. For ush
mounting cut a clean hole measuring
64mm in diameter in the chosen area for
the sensor. Seal any large holes on ceiling
to prevent air current activation.
Step 2
Ensure that the mains power to the circuit
is switched o. Ensure terminal cover
and cable clamp are correctly tted with
screws supplied. Place the Live In into the
Terminal marked Live In and the switched
Live Out into the Live Out terminal.
Place the neutral into the connection
marked N for neutral. Please note that it is
essential that the Live In wire and the
switch Live Out and Neutral are identied
prior to commencing installation.
To connect multiple units connect the live
switch live and neutrals as shown in
Diagram 2. Turn o mains supply for
installation as live working is not
recommended and can damage the unit.
Step 3
For ush mounting fold the two arms up
into the vertical position and insert unit
into the hole. Release unit ensuring arms
are securely in place.
Step 4
Remove the fascia by turning anti-clockwise
to show the lux pot, time delay pot switches.
Please adjust the Lux Level and time delay
potentiometer gently without force as this is
a sensitive electronic part. After adjustment
please wait 30 seconds for changes to take
eect. It is recommend product is set up
initially on the minimum 30 second time
setting to enable an ecient walk test to
check PIR area coverage.
Step 5
To manually set the desired Lux level adjust
potentiometer between (+) and (–). This allows
the PIR to only switch ON ambient light
levels is below the set level. Adjustment to
the plus (+) will allow the PIR to always
switch ON when triggered. A minus - setting
will eectively switch PIR OFF completely.
Step 6
To increase the time delay turn the
potentiometer toward the High (H) and
to decrease the time delay turn the
potentiometer toward the Low (L).
Step 7
The PIR will take approximately 1 minute
to initialize and will ash occasionally after
the mains power is rst applied to allow
the sensor to learn its environment.
The load will be ON and after initializing
will then switch o if there is no
detection in the zones.

Problem Resolution
Lights will not
switch OFF
• Check terminal connections.
• Check timings.
• PIR is too close to load – Re-position away from lighting, heating and forced air ventilation.
• PIR is switching low wattage or LED loads – Fit Capacitor as stated in instructions PFCC-1.
• PIR is re triggered – Check area is left unoccupied for longer that time setting using an accurate time piece.
Lights will not
switch ON
• Check Terminal connections.
• Lux set too low – Turn UP lux level to the PLUS (+) setting and wait for
sensor to adjust.
Light switches
OFF then
immediately
comes back ON
• Check terminal connections.
• PIR is detecting normally – Find source that is triggering PIR.
• PIR is seeing infra red heat from the load- Re-position away from heat source (See Positioning).
• PIR is switching low wattage or LED loads- Fit Capacitor PFCC-1 across switch live and
neutral of load.
• PIR is switching a contactor and the contactor chatters or stays ON - Fit a PFCC-1 capacitor
across the switch live and neutral of the contactor coil.
Troubleshooting
Operation of the Unit
• In standard operation the PIR will now
sense infra red heat when a person
or source of heat passes through
the detection zone. Each time the PIR is
triggered it will reset the timer back
to the start of the timing period. The unit
will then wait 5 seconds before allowing
the PIR to sense and re trigger the
timing period again.
• If no one is present in the room or the
detection zone is not passed through,
during its set time period, the timer
will time out, turning o the lights
or appliance.
• The PIR unit will only trigger the
lights or appliance if the ambient light
level is below that set on the lux
level adjustment.
