11.12 LE3 Test lamp
The test lamp LE3 is used to test the function of all flame detectors over distances
up to 10 m. It is housed in a transportable case together with the required
accessories. In addition, the case enables the test lamp to be kept in a dust-free
condition.
The quartz-halogen lamp used creates an intense ray of light. This helps to align
the lamp on the detector which is to be tested. During the detector test, the ray of
light is modulated. The luminous intensity can be set in accordance with the
distance.
The power is supplied by a rechargeable battery. Since the color of the light
depends on the charge state of the battery, it must always be charged in buffer
mode. A special charger is available for this.
