Det-Tronics W867 User manual

APPLICATION
The Det-Tronics W867 Ultraviolet/Infrared (UV/IR) Test
Lamp is a portable, battery operated source of
ultraviolet and infrared radiation that can be used for
periodic inspection of UV, single frequency IR and
UV/IR flame detection systems. It produces UV and IR
radiation to verify response of the flame detection
system without the need for an open flame, and is
suitable for use in hazardous (classified) areas. (Note:
Det-Tronics Dual Frequency IR detectors require the
model W868 Dual Frequency IR Test Lamp for testing.)

SAFETY PRECAUTIONS
Exposure to ultraviolet radiation from the W867
Test Lamp can be damaging to the eyes. Do not
look directly into the window of the test lamp
when it is on.
OPERATION
To operate the W867 Test Lamp, push the “ON” button
(see Figure 2) and aim the test lamp at the detector.
The UV and IR emitting lamp inside the W867 will flash
on and off at a rate of approximately 2 times per
second. This flashing operation satisfies the “flicker”
circuit in the IR detector. Response of the detection
system will depend upon the distance between the
W867 and the detector, and upon the sensitivity
programmed into the detection system. It may be
necessary to decrease the distance between the
detector and the test lamp in order to obtain a
response.
Do not operate the test lamp longer than is necessary
to actuate the detector. Each detector can be checked
with less than 30 seconds of operating time. It is
important to avoid discharging the battery to the point
where the battery charge level Indicating LED (see
Figure 2) is on steady. Refer to the Battery
Maintenance section of these instructions for further
information.
CAUTION
Do not remove the shock insulators from the lens
cap or battery storage compartment.
SYSTEM CHECKOUT
A system checkout should be performed after
installation is complete. A periodic maintenance
checkout (with minimum frequency of once every six
months) should be scheduled to ensure that the system
is in proper operating condition. Depending on the
degree of hazard and the amount of contaminants in
the atmosphere, the checkout can be scheduled more
often. Note that oil films will significantly reduce the
transmission of ultraviolet radiation through the detector
windows.
For specific system checkout instructions, see the
“Checkout Procedure” section of the instruction manual
for the flame detection system being used.
The W867 Test Lamp is a safe, portable UV/IR source
for external testing and verification of the response of
Det-Tronics UV, single frequency IR, and UV/IR
detectors. It is suitable for use in hazardous
(classified) areas, but is not a substitute for an actual
open flame test.

SERVICE PROCEDURES
BATTERY MAINTENANCE
A battery charge level indicating LED and the charger
cable connection for recharging the battery are located
beneath a removable windowed plug in front of the ON
pushbutton switch. See Figure 2. To maintain the
explosion-proof rating of the W867, the plug must be
installed whenever the battery is not being charged. To
determine the battery charge level, press the ON
pushbutton and observe the Indicating LED. When the
battery is fully charged, the red Indicating LED (viewed
through the window) is off. When the battery reaches a
marginal level, the Indicating LED will flash on and off.
The battery should be recharged at this time. If the
Indicating LED is on continuously, the battery is at a
very low level and the test lamp should not be operated
until the battery has been recharged.
WARNING
The life of the battery is significantly reduced if it
is operated when the red LED is on continuously.
RECHARGING
A 12 volt dc, 0.3 ampere battery charger is provided to
supply dc voltage from an ac outlet for recharging the
W867 battery. Battery chargers are available to
operate on either 120 vac 60 Hz or 220 vac 50 Hz
(optional). This plug-in battery charger contains a
Power On LED to indicate when the charger is plugged
in and a Fast Charge LED to indicate when the battery
is being charged.
WARNING
Do not operate the W867 Test Lamp when the
battery is charging.
Do not recharge the battery in a hazardous area.
To recharge the battery, first remove the windowed plug
to gain access to the recharge connection. Plug the
charger cable plug into the battery. Plug the battery
charger into the appropriate ac outlet. The Power On
and Fast Charge LEDs on the battery charger should
be on. When the battery is fully charged, the Fast
Charge LED will go out. This should take from 12 to 14
hours from a discharged state.
To return the W867 Test Lamp to service, unplug the
battery charger from the ac outlet. Disconnect the
charger cable from the battery. Replace the windowed
plug. Press the ON pushbutton and observe the
indicating LED on the battery. The indicating LED
should be off, which shows that the battery is fully
charged and ready to operate.
DEVICE REPAIR AND RETURN
The W867 UV/IR Test Lamp is not designed to be
repaired in the field. If the test lamp fails to operate
after fully charging the battery, return it to the factory for
repair.
Prior to returning devices, contact the nearest local
Detector Electronics office so that a Service Order
number can be assigned. A written statement
describing the malfunction must accompany the
returned device or component to expedite finding the
cause of the failure.
Pack the unit properly. Use sufficient packing material.
Return all equipment transportation prepaid to the
factory in Minneapolis.
